+ * **Note:** This document is an in-depth reference of all directive options. + * For a gentle introduction to directives with examples of common use cases, + * see the {@link guide/directive directive guide}. + *
+ * + * ## Comprehensive Directive API + * + * There are many different options for a directive. + * + * The difference resides in the return value of the factory function. + * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)} + * that defines the directive properties, or just the `postLink` function (all other properties will have + * the default values). + * + *
+ * **Best Practice:** It's recommended to use the "directive definition object" form. + *
+ * + * Here's an example directive declared with a Directive Definition Object: + * + * ```js + * var myModule = angular.module(...); + * + * myModule.directive('directiveName', function factory(injectables) { + * var directiveDefinitionObject = { + * {@link $compile#-priority- priority}: 0, + * {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... }, + * // or + * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... }, + * {@link $compile#-transclude- transclude}: false, + * {@link $compile#-restrict- restrict}: 'A', + * {@link $compile#-templatenamespace- templateNamespace}: 'html', + * {@link $compile#-scope- scope}: false, + * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, + * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier', + * {@link $compile#-bindtocontroller- bindToController}: false, + * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], + * {@link $compile#-multielement- multiElement}: false, + * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) { + * return { + * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, + * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } + * } + * // or + * // return function postLink( ... ) { ... } + * }, + * // or + * // {@link $compile#-link- link}: { + * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, + * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } + * // } + * // or + * // {@link $compile#-link- link}: function postLink( ... ) { ... } + * }; + * return directiveDefinitionObject; + * }); + * ``` + * + *
+ * **Note:** Any unspecified options will use the default value. You can see the default values below. + *
+ * + * Therefore the above can be simplified as: + * + * ```js + * var myModule = angular.module(...); + * + * myModule.directive('directiveName', function factory(injectables) { + * var directiveDefinitionObject = { + * link: function postLink(scope, iElement, iAttrs) { ... } + * }; + * return directiveDefinitionObject; + * // or + * // return function postLink(scope, iElement, iAttrs) { ... } + * }); + * ``` + * + * ### Life-cycle hooks + * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the + * directive: + * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and + * had their bindings initialized (and before the pre & post linking functions for the directives on + * this element). This is a good place to put initialization code for your controller. + * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The + * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an + * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a + * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will + * also be called when your bindings are initialized. + * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on + * changes. Any actions that you wish to take in response to the changes that you detect must be + * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook + * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not + * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; + * if detecting changes, you must store the previous value(s) for comparison to the current values. + * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing + * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in + * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent + * components will have their `$onDestroy()` hook called before child components. + * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link + * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. + * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since + * they are waiting for their template to load asynchronously and their own compilation and linking has been + * suspended until that occurs. + * + * #### Comparison with life-cycle hooks in the new Angular + * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are + * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular: + * + * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`. + * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor. + * In Angular you can only define hooks on the prototype of the Component class. + * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to + * `ngDoCheck` in Angular. + * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be + * propagated throughout the application. + * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an + * error or do nothing depending upon the state of `enableProdMode()`. + * + * #### Life-cycle hook examples + * + * This example shows how you can check for mutations to a Date object even though the identity of the object + * has not changed. + * + * + * + * angular.module('do-check-module', []) + * .component('app', { + * template: + * 'Month: ' + + * 'Date: {{ $ctrl.date }}' + + * '', + * controller: function() { + * this.date = new Date(); + * this.month = this.date.getMonth(); + * this.updateDate = function() { + * this.date.setMonth(this.month); + * }; + * } + * }) + * .component('test', { + * bindings: { date: '<' }, + * template: + * '
{{ $ctrl.log | json }}
', + * controller: function() { + * var previousValue; + * this.log = []; + * this.$doCheck = function() { + * var currentValue = this.date && this.date.valueOf(); + * if (previousValue !== currentValue) { + * this.log.push('doCheck: date mutated: ' + this.date); + * previousValue = currentValue; + * } + * }; + * } + * }); + * + * + * + * + * + * + * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the + * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large + * arrays or objects can have a negative impact on your application performance.) + * + * + * + *
+ * + * + * 
{{ items }}
+ * + *
+ * + * + * angular.module('do-check-module', []) + * .component('test', { + * bindings: { items: '<' }, + * template: + * '
{{ $ctrl.log | json }}
', + * controller: function() { + * this.log = []; + * + * this.$doCheck = function() { + * if (this.items_ref !== this.items) { + * this.log.push('doCheck: items changed'); + * this.items_ref = this.items; + * } + * if (!angular.equals(this.items_clone, this.items)) { + * this.log.push('doCheck: items mutated'); + * this.items_clone = angular.copy(this.items); + * } + * }; + * } + * }); + * + * + * + * + * ### Directive Definition Object + * + * The directive definition object provides instructions to the {@link ng.$compile + * compiler}. The attributes are: + * + * #### `multiElement` + * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recommended that this feature be used on directives + * which are not strictly behavioral (such as {@link ngClick}), and which + * do not manipulate or replace child nodes (such as {@link ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). Note that expressions + * and other directives used in the directive's template will also be excluded from execution. + * + * #### `scope` + * The scope property can be `false`, `true`, or an object: + * + * * **`false` (default):** No scope will be created for the directive. The directive will use its + * parent's scope. + * + * * **`true`:** A new child scope that prototypically inherits from its parent will be created for + * the directive's element. If multiple directives on the same element request a new scope, + * only one new scope is created. + * + * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template. + * The 'isolate' scope differs from normal scope in that it does not prototypically + * inherit from its parent scope. This is useful when creating reusable components, which should not + * accidentally read or modify data in the parent scope. Note that an isolate scope + * directive without a `template` or `templateUrl` will not apply the isolate scope + * to its children elements. + * + * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the + * directive's element. These local properties are useful for aliasing values for templates. The keys in + * the object hash map to the name of the property on the isolate scope; the values define how the property + * is bound to the parent scope, via matching attributes on the directive's element: + * + * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is + * always a string since DOM attributes are strings. If no `attr` name is specified then the + * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`, + * the directive's scope property `localName` will reflect the interpolated value of `hello + * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's + * scope. The `name` is read from the parent scope (not the directive's scope). + * + * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression + * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. + * If no `attr` name is specified then the attribute name is assumed to be the same as the local + * name. Given `` and the isolate scope definition `scope: { + * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the + * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in + * `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute + * isn't optional and doesn't exist, an exception + * ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes + * to the local value, since it will be impossible to sync them back to the parent scope. + * + * By default, the {@link ng.$rootScope.Scope#$watch `$watch`} + * method is used for tracking changes, and the equality check is based on object identity. + * However, if an object literal or an array literal is passed as the binding expression, the + * equality check is done by value (using the {@link angular.equals} function). It's also possible + * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection + * `$watchCollection`}: use `=*` or `=*attr` + * + * * `<` or `` and directive definition of + * `scope: { localModel:'` and the isolate scope definition `scope: { + * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for + * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope + * via an expression to the parent scope. This can be done by passing a map of local variable names + * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` + * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. + * + * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression. + * The marker must come after the mode and before the attribute name. + * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples. + * This is useful to refine the interface directives provide. + * One subtle difference between optional and non-optional happens **when the binding attribute is not + * set**: + * - the binding is optional: the property will not be defined + * - the binding is not optional: the property is defined + * + * ```js + *app.directive('testDir', function() { + return { + scope: { + notoptional: '=', + optional: '=?', + }, + bindToController: true, + controller: function() { + this.$onInit = function() { + console.log(this.hasOwnProperty('notoptional')) // true + console.log(this.hasOwnProperty('optional')) // false } + } } - - this.$$compose(); - return this; - }, - - /** - * @ngdoc method - * @name $location#hash - * - * @description - * This method is getter / setter. - * - * Returns the hash fragment when called without any parameters. - * - * Changes the hash fragment when called with a parameter and returns `$location`. - * - * - * ```js - * // given URL http://example.com/#/some/path?foo=bar&baz=xoxo#hashValue - * var hash = $location.hash(); - * // => "hashValue" - * ``` - * - * @param {(string|number)=} hash New hash fragment - * @return {string} hash - */ - hash: locationGetterSetter('$$hash', function(hash) { - return hash !== null ? hash.toString() : ''; - }), - - /** - * @ngdoc method - * @name $location#replace - * - * @description - * If called, all changes to $location during the current `$digest` will replace the current history - * record, instead of adding a new one. - */ - replace: function() { - this.$$replace = true; - return this; - } -}; - -forEach([LocationHashbangInHtml5Url, LocationHashbangUrl, LocationHtml5Url], function(Location) { - Location.prototype = Object.create(locationPrototype); - - /** - * @ngdoc method - * @name $location#state - * - * @description - * This method is getter / setter. - * - * Return the history state object when called without any parameter. - * - * Change the history state object when called with one parameter and return `$location`. - * The state object is later passed to `pushState` or `replaceState`. - * - * NOTE: This method is supported only in HTML5 mode and only in browsers supporting - * the HTML5 History API (i.e. methods `pushState` and `replaceState`).

The following points will help explain these limitations. + * For simplicity only two directives are taken into account, but it is also applicable for several directives: + * + * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope + * * **child scope** + **no scope** => Both directives will share one single child scope + * * **child scope** + **child scope** => Both directives will share one single child scope + * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use + * its parent's scope + * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot + * be applied to the same element. + * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives + * cannot be applied to the same element. + * + * + * #### `bindToController` + * This property is used to bind scope properties directly to the controller. It can be either + * `true` or an object hash with the same format as the `scope` property. + * + * When an isolate scope is used for a directive (see above), `bindToController: true` will + * allow a component to have its properties bound to the controller, rather than to scope. + * + * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller + * properties. You can access these bindings once they have been initialized by providing a controller method called + * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings + * initialized. + * + * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. + * This will set up the scope bindings to the controller directly. Note that `scope` can still be used + * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate + * scope (useful for component directives). + * + * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. + * + * + * #### `controller` + * Controller constructor function. The controller is instantiated before the + * pre-linking phase and can be accessed by other directives (see + * `require` attribute). This allows the directives to communicate with each other and augment + * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: + * + * * `$scope` - Current scope associated with the element + * * `$element` - Current element + * * `$attrs` - Current attributes object for the element + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: + * * `scope`: (optional) override the scope. + * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. + * * `futureParentElement` (optional): + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkingFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like ``). + * * See also the `directive.templateNamespace` property. + * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) + * then the default transclusion is provided. + * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns + * `true` if the specified slot contains content (i.e. one or more DOM nodes). + * + * #### `require` + * Require another directive and inject its controller as the fourth argument to the linking function. The + * `require` property can be a string, an array or an object: + * * a **string** containing the name of the directive to pass to the linking function + * * an **array** containing the names of directives to pass to the linking function. The argument passed to the + * linking function will be an array of controllers in the same order as the names in the `require` property + * * an **object** whose property values are the names of the directives to pass to the linking function. The argument + * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding + * controllers. + * + * If the `require` property is an object and `bindToController` is truthy, then the required controllers are + * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers + * have been constructed but before `$onInit` is called. + * If the name of the required controller is the same as the local name (the key), the name can be + * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. + * See the {@link $compileProvider#component} helper for an example of how this can be used. + * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is + * raised (unless no link function is specified and the required controllers are not being bound to the directive + * controller, in which case error checking is skipped). The name can be prefixed with: + * + * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. + * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. + * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. + * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. + * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass + * `null` to the `link` fn if not found. + * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass + * `null` to the `link` fn if not found. + * + * + * #### `controllerAs` + * Identifier name for a reference to the controller in the directive's scope. + * This allows the controller to be referenced from the directive template. This is especially + * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible + * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the + * `controllerAs` reference might overwrite a property that already exists on the parent scope. + * + * + * #### `restrict` + * String of subset of `EACM` which restricts the directive to a specific directive + * declaration style. If omitted, the defaults (elements and attributes) are used. + * + * * `E` - Element name (default): `` + * * `A` - Attribute (default): `
` + * * `C` - Class: `
` + * * `M` - Comment: `` + * + * + * #### `templateNamespace` + * String representing the document type used by the markup in the template. + * AngularJS needs this information as those elements need to be created and cloned + * in a special way when they are defined outside their usual containers like `` and ``. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `` or ``. + * * `svg` - The root nodes in the template are SVG elements (excluding ``). + * * `math` - The root nodes in the template are MathML elements (excluding ``). + * + * If no `templateNamespace` is specified, then the namespace is considered to be `html`. + * + * #### `template` + * HTML markup that may: + * * Replace the contents of the directive's element (default). + * * Replace the directive's element itself (if `replace` is true - DEPRECATED). + * * Wrap the contents of the directive's element (if `transclude` is true). + * + * Value may be: + * + * * A string. For example `
{{delete_str}}
`. + * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` + * function api below) and returns a string value. + * + * + * #### `templateUrl` + * This is similar to `template` but the template is loaded from the specified URL, asynchronously. + * + * Because template loading is asynchronous the compiler will suspend compilation of directives on that element + * for later when the template has been resolved. In the meantime it will continue to compile and link + * sibling and parent elements as though this element had not contained any directives. + * + * The compiler does not suspend the entire compilation to wait for templates to be loaded because this + * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the + * case when only one deeply nested directive has `templateUrl`. + * + * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}. + * + * You can specify `templateUrl` as a string representing the URL or as a function which takes two + * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns + * a string value representing the url. In either case, the template URL is passed through {@link + * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. + * + * + * #### `replace` + *
+ * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+). + *

The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared.

+ * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + *

The exact value depends on the directive's `require` property: + * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one + * * `string`: the controller instance + * * `array`: array of controller instances + * + * If a required controller cannot be found, and it is optional, the instance is `null`, + * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. + * + * Note that you can also require the directive's own controller - it will be made available like + * any other controller. + * + * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. + * This is the same as the `$transclude` parameter of directive controllers, + * see {@link ng.$compile#-controller- the controller section for details}. + * `function([scope], cloneLinkingFn, futureParentElement)`. + * + * #### Pre-linking function + * + * Executed before the child elements are linked. Not safe to do DOM transformation since the + * compiler linking function will fail to locate the correct elements for linking. + * + * #### Post-linking function + * + * Executed after the child elements are linked. + * + * Note that child elements that contain `templateUrl` directives will not have been compiled + * and linked since they are waiting for their template to load asynchronously and their own + * compilation and linking has been suspended until that occurs. + * + * It is safe to do DOM transformation in the post-linking function on elements that are not waiting + * for their async templates to be resolved. + * + * + * ### Transclusion + * + * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and + * copying them to another part of the DOM, while maintaining their connection to the original AngularJS + * scope from where they were taken. + * + * Transclusion is used (often with {@link ngTransclude}) to insert the + * original contents of a directive's element into a specified place in the template of the directive. + * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded + * content has access to the properties on the scope from which it was taken, even if the directive + * has isolated scope. + * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. + * + * This makes it possible for the widget to have private state for its template, while the transcluded + * content has access to its originating scope. + * + *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + *
+ * + * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the + * directive's element, the entire element or multiple parts of the element contents: + * + * * `true` - transclude the content (i.e. the child nodes) of the directive's element. + * * `'element'` - transclude the whole of the directive's element including any directives on this + * element that are defined at a lower priority than this directive. When used, the `template` + * property is ignored. + * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. + * + * **Multi-slot transclusion** is declared by providing an object for the `transclude` property. + * + * This object is a map where the keys are the name of the slot to fill and the value is an element selector + * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) + * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). + * + * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}. + * + * If the element selector is prefixed with a `?` then that slot is optional. + * + * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to + * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. + * + * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements + * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call + * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and + * injectable into the directive's controller. + * + * + * #### Transclusion Functions + * + * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion + * function** to the directive's `link` function and `controller`. This transclusion function is a special + * **linking function** that will return the compiled contents linked to a new transclusion scope. + * + *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since + * ngTransclude will deal with it for us. + *
+ * + * If you want to manually control the insertion and removal of the transcluded content in your directive + * then you must use this transclude function. When you call a transclude function it returns a jqLite/JQuery + * object that contains the compiled DOM, which is linked to the correct transclusion scope. + * + * When you call a transclusion function you can pass in a **clone attach function**. This function accepts + * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded + * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. + * + *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function + * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. + *
+ * + * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone + * attach function**: + * + * ```js + * var transcludedContent, transclusionScope; + * + * $transclude(function(clone, scope) { + * element.append(clone); + * transcludedContent = clone; + * transclusionScope = scope; + * }); + * ``` + * + * Later, if you want to remove the transcluded content from your DOM then you should also destroy the + * associated transclusion scope: + * + * ```js + * transcludedContent.remove(); + * transclusionScope.$destroy(); + * ``` + * + *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive + * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), + * then you are also responsible for calling `$destroy` on the transclusion scope. + *
+ * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transcluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + *
+ *
+ *
+ *
+ *
+ *
+ * ``` + * + * The `$parent` scope hierarchy will look like this: + * + ``` + - $rootScope + - isolate + - transclusion + ``` + * + * but the scopes will inherit prototypically from different scopes to their `$parent`. + * + ``` + - $rootScope + - transclusion + - isolate + ``` + * + * + * ### Attributes + * + * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the + * `link()` or `compile()` functions. It has a variety of uses. + * + * * *Accessing normalized attribute names:* Directives like `ngBind` can be expressed in many ways: + * `ng:bind`, `data-ng-bind`, or `x-ng-bind`. The attributes object allows for normalized access + * to the attributes. + * + * * *Directive inter-communication:* All directives share the same instance of the attributes + * object which allows the directives to use the attributes object as inter directive + * communication. + * + * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object + * allowing other directives to read the interpolated value. + * + * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes + * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also + * the only way to easily get the actual value because during the linking phase the interpolation + * hasn't been evaluated yet and so the value is at this time set to `undefined`. + * + * ```js + * function linkingFn(scope, elm, attrs, ctrl) { + * // get the attribute value + * console.log(attrs.ngModel); + * + * // change the attribute + * attrs.$set('ngModel', 'new value'); + * + * // observe changes to interpolated attribute + * attrs.$observe('ngModel', function(value) { + * console.log('ngModel has changed value to ' + value); + * }); + * } + * ``` + * + * ## Example + * + *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is + * to illustrate how `$compile` works. + *
+ * + + + +
+

The `cloneAttachFn` is + * called as:
`cloneAttachFn(clonedElement, scope)` where: + * + * * `clonedElement` - is a clone of the original `element` passed into the compiler. + * * `scope` - is the current scope with which the linking function is working with. + * + * * `options` - An optional object hash with linking options. If `options` is provided, then the following + * keys may be used to control linking behavior: + * + * * `parentBoundTranscludeFn` - the transclude function made available to + * directives; if given, it will be passed through to the link functions of + * directives found in `element` during compilation. + * * `transcludeControllers` - an object hash with keys that map controller names + * to a hash with the key `instance`, which maps to the controller instance; + * if given, it will make the controllers available to directives on the compileNode: + * ``` + * { + * parent: { + * instance: parentControllerInstance + * } + * } + * ``` + * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add + * the cloned elements; only needed for transcludes that are allowed to contain non HTML + * elements (e.g. SVG elements). See also the `directive.controller` property. + * + * Calling the linking function returns the element of the template. It is either the original + * element passed in, or the clone of the element if the `cloneAttachFn` is provided. + * + * After linking the view is not updated until after a call to `$digest`, which typically is done by + * AngularJS automatically. + * + * If you need access to the bound view, there are two ways to do it: + * + * - If you are not asking the linking function to clone the template, create the DOM element(s) + * before you send them to the compiler and keep this reference around. + * ```js + * var element = angular.element('

{{total}}

'); + * $compile(element)(scope); + * ``` + * + * - if on the other hand, you need the element to be cloned, the view reference from the original + * example would not point to the clone, but rather to the original template that was cloned. In + * this case, you can access the clone either via the `cloneAttachFn` or the value returned by the + * linking function: + * ```js + * var templateElement = angular.element('

{{total}}

'); + * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { + * // Attach the clone to DOM document at the right place. + * }); + * + * // Now we have reference to the cloned DOM via `clonedElement`. + * // NOTE: The `clonedElement` returned by the linking function is the same as the + * // `clonedElement` passed to `cloneAttachFn`. + * ``` + * + * + * For information on how the compiler works, see the + * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide. + * + * @knownIssue + * + * ### Double Compilation + * + Double compilation occurs when an already compiled part of the DOM gets + compiled again.

+ * **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use, + * mainly due to the issues listed here. It has been completely removed in the new Angular. + *
+ * + * #### Attribute values are not merged + * + * When a `replace` directive encounters the same attribute on the original and the replace node, + * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of + * the `style` attribute. + * ```html + * Original Node: + * Replace Template: + * Result: + * ``` + * + * That means attributes that contain AngularJS expressions will not be merged correctly, e.g. + * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error: + * + * ```html + * Original Node: + * Replace Template: + * Result: + * ``` + * + * See issue [#5695](https://github.com/angular/angular.js/issues/5695). + * + * #### Directives are not deduplicated before compilation + * + * When the original node and the replace template declare the same directive(s), they will be + * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler + * does not deduplicate them. In many cases, this is not noticeable, but e.g. {@link ngModel} will + * attach `$formatters` and `$parsers` twice. + * + * See issue [#2573](https://github.com/angular/angular.js/issues/2573). + * + * #### `transclude: element` in the replace template root can have unexpected effects + * + * When the replace template has a directive at the root node that uses + * {@link $compile#-transclude- `transclude: element`}, e.g. + * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect. + * See the following issues: + * + * - Incorrect scope on replaced element: + * [#9837](https://github.com/angular/angular.js/issues/9837) + * - Different DOM between `template` and `templateUrl`: + * [#10612](https://github.com/angular/angular.js/issues/14326) + * + */ -var OPERATORS = createMap(); -forEach('+ - * / % === !== == != < > <= >= && || ! = |'.split(' '), function(operator) { OPERATORS[operator] = true; }); -var ESCAPE = {'n':'\n', 'f':'\f', 'r':'\r', 't':'\t', 'v':'\v', '\'':'\'', '"':'"'}; +/** + * @ngdoc directive + * @name ngProp + * @restrict A + * @element ANY + * + * @usage + * + * ```html + * + * + * ``` + * + * or with uppercase letters in property (e.g. "propName"): + * + * + * ```html + * + * + * ``` + * + * + * @description + * The `ngProp` directive binds an expression to a DOM element property. + * `ngProp` allows writing to arbitrary properties by including + * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to + * the `value` property. + * + * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives + * handle the most common use cases (instead of the above example, you would use {@link ngValue}). + * + * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements) + * often use custom properties to hold data, and `ngProp` can be used to provide input to these + * custom elements. + * + * ## Binding to camelCase properties + * + * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped. + * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so + * `innerHTML` must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an + * example, and for binding HTML {@link ngBindHtml} should be used. + * + * ## Security + * + * Binding expressions to arbitrary properties poses a security risk, as properties like `innerHTML` + * can insert potentially dangerous HTML into the application, e.g. script tags that execute + * malicious code. + * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}. + * This means vulnerable properties require their content to be "trusted", based on the + * context of the property. For example, the `innerHTML` is in the `HTML` context, and the + * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to + * this property are trusted as a `RESOURCE_URL`. + * + * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is + * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for + * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al. + * + * In some cases you can also rely upon automatic sanitization of untrusted values - see below. + * + * Based on the context, other options may exist to mark a value as trusted / configure the behavior + * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use + * the {@link $sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList()} + * and {@link $sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList()}. + * + * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}. + * + * ### HTML Sanitization + * + * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the + * content. + * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the + * potentially dangerous HTML, e.g. strip non-trusted tags and attributes when binding to + * `innerHTML`. + * + * @example + * ### Binding to different contexts + * + * + * + * angular.module('exampleNgProp', []) + * .component('main', { + * templateUrl: 'main.html', + * controller: function($sce) { + * this.safeContent = 'Safe content'; + * this.unsafeContent = ''; + * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent); + * } + * }); + * + * + *

This is similar to the native Promise implementation from ES6, - * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by + * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing. * - * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are - * available yet. + * ## Example: * - * It can be used like so: + * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught + * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead + * of `$log.error()`. * * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). - * - * function asyncGreet(name) { - * // perform some asynchronous operation, resolve or reject the promise when appropriate. - * return $q(function(resolve, reject) { - * setTimeout(function() { - * if (okToGreet(name)) { - * resolve('Hello, ' + name + '!'); - * } else { - * reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * }); - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }); + * angular. + * module('exceptionOverwrite', []). + * factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) { + * return function myExceptionHandler(exception, cause) { + * logErrorsToBackend(exception, cause); + * $log.warn(exception, cause); + * }; + * }]); * ``` * - * Note: progress/notify callbacks are not currently supported via the ES6-style interface. - * - * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. - * - * However, the more traditional CommonJS-style usage is still available, and documented below. - * - * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an - * interface for interacting with an object that represents the result of an action that is - * performed asynchronously, and may or may not be finished at any given point in time. - * - * From the perspective of dealing with error handling, deferred and promise APIs are to - * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + *
+ * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind` + * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler} + * (unless executed during a digest). * - * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). + * If you wish, you can manually delegate exceptions, e.g. + * `try { ... } catch(e) { $exceptionHandler(e); }` * - * function asyncGreet(name) { - * var deferred = $q.defer(); + * @param {Error} exception Exception associated with the error. + * @param {string=} cause Optional information about the context in which + * the error was thrown. * - * setTimeout(function() { - * deferred.notify('About to greet ' + name + '.'); - * - * if (okToGreet(name)) { - * deferred.resolve('Hello, ' + name + '!'); - * } else { - * deferred.reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * - * return deferred.promise; - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }, function(update) { - * alert('Got notification: ' + update); - * }); - * ``` - * - * At first it might not be obvious why this extra complexity is worth the trouble. The payoff - * comes in the way of guarantees that promise and deferred APIs make, see - * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. - * - * Additionally the promise api allows for composition that is very hard to do with the - * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. - * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the - * section on serial or parallel joining of promises. - * - * ## The Deferred API - * - * A new instance of deferred is constructed by calling `$q.defer()`. - * - * The purpose of the deferred object is to expose the associated Promise instance as well as APIs - * that can be used for signaling the successful or unsuccessful completion, as well as the status - * of the task. - * - * **Methods** - * - * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection - * constructed via `$q.reject`, the promise will be rejected instead. - * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to - * resolving it with a rejection constructed via `$q.reject`. - * - `notify(value)` - provides updates on the status of the promise's execution. This may be called - * multiple times before the promise is either resolved or rejected. - * - * **Properties** - * - * - promise – `{Promise}` – promise object associated with this deferred. - * - * - * ## The Promise API - * - * A new promise instance is created when a deferred instance is created and can be retrieved by - * calling `deferred.promise`. - * - * The purpose of the promise object is to allow for interested parties to get access to the result - * of the deferred task when it completes. - * - * **Methods** - * - * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or - * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously - * as soon as the result is available. The callbacks are called with a single argument: the result - * or rejection reason. Additionally, the notify callback may be called zero or more times to - * provide a progress indication, before the promise is resolved or rejected. - * - * This method *returns a new promise* which is resolved or rejected via the return value of the - * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved - * with the value which is resolved in that promise using - * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). - * It also notifies via the return value of the `notifyCallback` method. The promise cannot be - * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback - * arguments are optional. - * - * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` - * - * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, - * but to do so without modifying the final value. This is useful to release resources or do some - * clean-up that needs to be done whether the promise was rejected or resolved. See the [full - * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for - * more information. - * - * ## Chaining promises - * - * Because calling the `then` method of a promise returns a new derived promise, it is easily - * possible to create a chain of promises: - * - * ```js - * promiseB = promiseA.then(function(result) { - * return result + 1; - * }); - * - * // promiseB will be resolved immediately after promiseA is resolved and its value - * // will be the result of promiseA incremented by 1 - * ``` - * - * It is possible to create chains of any length and since a promise can be resolved with another - * promise (which will defer its resolution further), it is possible to pause/defer resolution of - * the promises at any point in the chain. This makes it possible to implement powerful APIs like - * $http's response interceptors. - * - * - * ## Differences between Kris Kowal's Q and $q - * - * There are two main differences: - * - * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation - * mechanism in AngularJS, which means faster propagation of resolution or rejection into your - * models and avoiding unnecessary browser repaints, which would result in flickering UI. - * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains - * all the important functionality needed for common async tasks. - * - * ## Testing - * - * ```js - * it('should simulate promise', inject(function($q, $rootScope) { - * var deferred = $q.defer(); - * var promise = deferred.promise; - * var resolvedValue; - * - * promise.then(function(value) { resolvedValue = value; }); - * expect(resolvedValue).toBeUndefined(); - * - * // Simulate resolving of promise - * deferred.resolve(123); - * // Note that the 'then' function does not get called synchronously. - * // This is because we want the promise API to always be async, whether or not - * // it got called synchronously or asynchronously. - * expect(resolvedValue).toBeUndefined(); - * - * // Propagate promise resolution to 'then' functions using $apply(). - * $rootScope.$apply(); - * expect(resolvedValue).toEqual(123); - * })); - * ``` - * - * @param {function(function, function)} resolver Function which is responsible for resolving or - * rejecting the newly created promise. The first parameter is a function which resolves the - * promise, the second parameter is a function which rejects the promise. - * - * @returns {Promise} The newly created promise. - */ -/** - * @ngdoc provider - * @name $qProvider - * @this - * - * @description */ -function $QProvider() { - var errorOnUnhandledRejections = true; - this.$get = ['$rootScope', '$exceptionHandler', function($rootScope, $exceptionHandler) { - return qFactory(function(callback) { - $rootScope.$evalAsync(callback); - }, $exceptionHandler, errorOnUnhandledRejections); +function $ExceptionHandlerProvider() { + this.$get = ['$log', function($log) { + return function(exception, cause) { + $log.error.apply($log, arguments); + }; + }]; +} + +var $$ForceReflowProvider = /** @this */ function() { + this.$get = ['$document', function($document) { + return function(domNode) { + //the line below will force the browser to perform a repaint so + //that all the animated elements within the animation frame will + //be properly updated and drawn on screen.

These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - Accept: application/json, text/plain, \*/\* + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. For example: + * + * ``` + * module.run(function($http) { + * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; + * }); + * ``` + * + * In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, + * Use the `headers` property, setting the desired header to `undefined`. For example: + * + * ```js + * var req = { + * method: 'POST', + * url: 'http://example.com', + * headers: { + * 'Content-Type': undefined + * }, + * data: { test: 'test' } + * } + * + * $http(req).then(function(){...}, function(){...}); + * ``` + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + *
+ * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. + * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). + * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest + * function will be reflected on the scope and in any templates where the object is data-bound. + * To prevent this, transform functions should have no side-effects. + * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. + *
+ * + * ### Default Transformations + * + * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and + * `defaults.transformResponse` properties. If a request does not provide its own transformations + * then these will be applied. + * + * You can augment or replace the default transformations by modifying these properties by adding to or + * replacing the array. + * + * AngularJS provides the following default transformations: + * + * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is + * an array with one function that does the following: + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is + * an array with one function that does the following: + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If the `Content-Type` is `application/json` or the response looks like JSON, + * deserialize it using a JSON parser. + * + * + * ### Overriding the Default Transformations Per Request + * + * If you wish to override the request/response transformations only for a single request then provide + * `transformRequest` and/or `transformResponse` properties on the configuration object passed + * into `$http`. + * + * Note that if you provide these properties on the config object the default transformations will be + * overwritten. If you wish to augment the default transformations then you must include them in your + * local transformation array. + * + * The following code demonstrates adding a new response transformation to be run after the default response + * transformations have been run. + * + * ```js + * function appendTransform(defaults, transform) { + * + * // We can't guarantee that the default transformation is an array + * defaults = angular.isArray(defaults) ? defaults : [defaults]; + * + * // Append the new transformation to the defaults + * return defaults.concat(transform); + * } + * + * $http({ + * url: '...', + * method: 'GET', + * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { + * return doTransform(value); + * }) + * }); + * ``` + * + * + * ## Caching + * + * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must + * set the config.cache value or the default cache value to TRUE or to a cache object (created + * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes + * precedence over the default cache value. + * + * In order to: + * * cache all responses - set the default cache value to TRUE or to a cache object + * * cache a specific response - set config.cache value to TRUE or to a cache object + * + * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, + * then the default `$cacheFactory("$http")` object is used. + * + * The default cache value can be set by updating the + * {@link ng.$http#defaults `$http.defaults.cache`} property or the + * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. + * + * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using + * the relevant cache object. The next time the same request is made, the response is returned + * from the cache without sending a request to the server. + * + * Take note that: + * + * * Only GET and JSONP requests are cached. + * * The cache key is the request URL including search parameters; headers are not considered. + * * Cached responses are returned asynchronously, in the same way as responses from the server. + * * If multiple identical requests are made using the same cache, which is not yet populated, + * one request will be made to the server and remaining requests will return the same response. + * * A cache-control header on the response does not affect if or how responses are cached. + * + * + * ## Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests. The interceptors leverage the {@link ng.$q + * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * AngularJS will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * AngularJS will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by + * which the attacker can trick an authenticated user into unknowingly executing actions on your + * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the + * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP + * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read + * the cookie, your server can be assured that the XHR came from JavaScript running on your + * domain. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be + * sure that only JavaScript running on your domain could have sent the request. The token must + * be unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The header will — by default — **not** be set for cross-domain requests. This + * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining + * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you + * want to, you can trust additional origins to also receive the XSRF token, by adding them + * to {@link ng.$httpProvider#xsrfTrustedOrigins xsrfTrustedOrigins}. This might be + * useful, for example, if your application, served from `example.com`, needs to access your API + * at `api.example.com`. + * See {@link ng.$httpProvider#xsrfTrustedOrigins $httpProvider.xsrfTrustedOrigins} for + * more details. + * + *
+ * **Warning**

For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e. + * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string. + * + * @knownIssue + * All directives and components must use the standard `{{` `}}` interpolation symbols + * in their templates. If you change the application interpolation symbols the {@link $compile} + * service will attempt to denormalize the standard symbols to the custom symbols. + * The denormalization process is not clever enough to know not to replace instances of the standard + * symbols where they would not normally be treated as interpolation symbols. For example in the following + * code snippet the closing braces of the literal object will get incorrectly denormalized: + * + * ``` + *

- * - * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of - * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is - * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to - * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things - * work because `$sce` delegates to `$sceDelegate` for these operations. - * - * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service. + * - Exposes the current URL in the browser address bar, so you can + * - Watch and observe the URL. + * - Change the URL. + * - Synchronizes the URL with the browser when the user + * - Changes the address bar. + * - Clicks the back or forward button (or clicks a History link). + * - Clicks on a link. + * - Represents the URL object as a set of methods (protocol, host, port, path, search, hash). * - * The default instance of `$sceDelegate` should work out of the box with little pain. While you - * can override it completely to change the behavior of `$sce`, the common case would - * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting - * your own trusted and banned resource lists for trusting URLs used for loading AngularJS resources - * such as templates.

Default implementation safely writes the message + * into the browser's console (if present). * - * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS. - * - * ## Strict Contextual Escaping - * - * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render - * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and - * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. - * - * ### Overview - * - * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in - * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically - * run security checks on them (sanitizations, trusted URL resource, depending on context), or throw - * when it cannot guarantee the security of the result. That behavior depends strongly on contexts: - * HTML can be sanitized, but template URLs cannot, for instance. - * - * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: - * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it - * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and - * render the input as-is, you will need to mark it as trusted for that context before attempting - * to bind it. - * - * As of version 1.2, AngularJS ships with SCE enabled by default. - * - * ### In practice - * - * Here's an example of a binding in a privileged context: - * - * ``` - * - *
- * ``` - * - * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE - * disabled, this application allows the user to render arbitrary HTML into the DIV, which would - * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog - * articles, etc. via bindings. (HTML is just one example of a context where rendering user - * controlled input creates security vulnerabilities.) - * - * For the case of HTML, you might use a library, either on the client side, or on the server side, - * to sanitize unsafe HTML before binding to the value and rendering it in the document. - * - * How would you ensure that every place that used these types of bindings was bound to a value that - * was sanitized by your library (or returned as safe for rendering by your server?) How can you - * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some - * properties/fields and forgot to update the binding to the sanitized value? - * - * To be secure by default, AngularJS makes sure bindings go through that sanitization, or - * any similar validation process, unless there's a good reason to trust the given value in this - * context. That trust is formalized with a function call. This means that as a developer, you - * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, - * you just need to ensure the values you mark as trusted indeed are safe - because they were - * received from your server, sanitized by your library, etc. You can organize your codebase to - * help with this - perhaps allowing only the files in a specific directory to do this. - * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then - * becomes a more manageable task. - * - * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} - * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to - * build the trusted versions of your values. - * - * ### How does it work? - * - * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted - * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as - * a way to enforce the required security context in your data sink. Directives use {@link - * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs - * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, - * when binding without directives, AngularJS will understand the context of your bindings - * automatically. + * The main purpose of this service is to simplify debugging and troubleshooting. * - * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link - * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly - * simplified): + * To reveal the location of the calls to `$log` in the JavaScript console, + * you can "blackbox" the AngularJS source in your browser: * - * ``` - * var ngBindHtmlDirective = ['$sce', function($sce) { - * return function(scope, element, attr) { - * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { - * element.html(value || ''); - * }); - * }; - * }]; - * ``` + * [Mozilla description of blackboxing](https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Black_box_a_source). + * [Chrome description of blackboxing](https://developer.chrome.com/devtools/docs/blackboxing). * - * ### Impact on loading templates + * Note: Not all browsers support blackboxing. * - * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as - * `templateUrl`'s specified by {@link guide/directive directives}. + * The default is to log `debug` messages. You can use + * {@link ng.$logProvider ng.$logProvider#debugEnabled} to change this. * - * By default, AngularJS only loads templates from the same domain and protocol as the application - * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl - * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or - * protocols, you may either add them to the {@link ng.$sceDelegateProvider#trustedResourceUrlList - * trustedResourceUrlList} or {@link ng.$sce#trustAsResourceUrl wrap them} into trusted values. - * - * *Please note*: - * The browser's - * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) - * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) - * policy apply in addition to this and may further restrict whether the template is successfully - * loaded. This means that without the right CORS policy, loading templates from a different domain - * won't work on all browsers. Also, loading templates from `file://` URL does not work on some - * browsers. - * - * ### This feels like too much overhead - * - * It's important to remember that SCE only applies to interpolation expressions. - * - * If your expressions are constant literals, they're automatically trusted and you don't need to - * call `$sce.trustAs` on them (e.g. - * `
`) just works (remember to include the - * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available - * when binding untrusted values to `$sce.HTML` context. - * AngularJS provides an implementation in `angular-sanitize.js`, and if you - * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in - * your application. - * - * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load - * templates in `ng-include` from your application's domain without having to even know about SCE. - * It blocks loading templates from other domains or loading templates over http from an https - * served document. You can change these by setting your own custom {@link - * ng.$sceDelegateProvider#trustedResourceUrlList trusted resource URL list} and {@link - * ng.$sceDelegateProvider#bannedResourceUrlList banned resource URL list} for matching such URLs. - * - * This significantly reduces the overhead. It is far easier to pay the small overhead and have an - * application that's secure and can be audited to verify that with much more ease than bolting - * security onto an application later. - * - * - * ### What trusted context types are supported? - * - * | Context | Notes | - * |---------------------|----------------| - * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | - * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | - * | `$sce.MEDIA_URL` | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. | - * | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.| - * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required.

The {@link $sceDelegateProvider#trustedResourceUrlList $sceDelegateProvider#trustedResourceUrlList()} and {@link $sceDelegateProvider#bannedResourceUrlList $sceDelegateProvider#bannedResourceUrlList()} can be used to restrict trusted origins for `RESOURCE_URL` | - * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | - * - * - *
- * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their - * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}. - * - * **As of 1.7.0, this is no longer the case.** - * - * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL` - * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate` - * service evaluates the expressions. - *
- * - * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs` - * functions aren't useful yet. This might evolve. - * - * ### Format of items in {@link ng.$sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList}/{@link ng.$sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList} - * - * Each element in these arrays must be one of the following: - * - * - **'self'** - * - The special **string**, `'self'`, can be used to match against all URLs of the **same - * domain** as the application document using the **same protocol**. - * - **String** (except the special value `'self'`) - * - The string is matched against the full *normalized / absolute URL* of the resource - * being tested (substring matches are not good enough.) - * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters - * match themselves. - * - `*`: matches zero or more occurrences of any character other than one of the following 6 - * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use - * for matching resource URL lists. - * - `**`: matches zero or more occurrences of *any* character. As such, it's not - * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. - * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might - * not have been the intention.) Its usage at the very end of the path is ok. (e.g. - * http://foo.example.com/templates/**). - * - **RegExp** (*see caveat below*) - * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax - * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to - * accidentally introduce a bug when one updates a complex expression (imho, all regexes should - * have good test coverage). For instance, the use of `.` in the regex is correct only in a - * small number of cases. A `.` character in the regex used when matching the scheme or a - * subdomain could be matched against a `:` or literal `.` that was likely not intended. It - * is highly recommended to use the string patterns and only fall back to regular expressions - * as a last resort. - * - The regular expression must be an instance of RegExp (i.e. not a string.) It is - * matched against the **entire** *normalized / absolute URL* of the resource being tested - * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags - * present on the RegExp (such as multiline, global, ignoreCase) are ignored. - * - If you are generating your JavaScript from some other templating engine (not - * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), - * remember to escape your regular expression (and be aware that you might need more than - * one level of escaping depending on your templating engine and the way you interpolated - * the value.) Do make use of your platform's escaping mechanism as it might be good - * enough before coding your own. E.g. Ruby has - * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) - * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). - * Javascript lacks a similar built in function for escaping. Take a look at Google - * Closure library's [goog.string.regExpEscape(s)]( - * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). - * - * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. - * - * ### Show me an example using SCE. - * - * - * - *

However, this is strongly discouraged. SCE gives you a lot of security benefits - * for little coding overhead. It will be much harder to take an SCE disabled application and - * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE - * for cases where you have a lot of existing code that was written before SCE was introduced and - * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if - * you are writing a library, you will cause security bugs applications using it. - * - * That said, here's how you can completely disable SCE: - * - * ``` - * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { - * // Completely disable SCE. For demonstration purposes only! - * // Do not use in new projects or libraries. - * $sceProvider.enabled(false); - * }); - * ``` + * @example + + + angular.module('logExample', []) + .controller('LogController', ['$scope', '$log', function($scope, $log) { + $scope.$log = $log; + $scope.message = 'Hello World!'; + }]); + + +

- * **Note**: If the array contains objects that reference themselves, filtering is not possible. - *
- * @param {string|Object|function()} expression The predicate to be used for selecting items from - * `array`. - * - * Can be one of: - * - * - `string`: The string is used for matching against the contents of the `array`. All strings or - * objects with string properties in `array` that match this string will be returned. This also - * applies to nested object properties. - * The predicate can be negated by prefixing the string with `!`. - * - * - `Object`: A pattern object can be used to filter specific properties on objects contained - * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items - * which have property `name` containing "M" and property `phone` containing "1". A special - * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match - * against any property of the object or its nested object properties. That's equivalent to the - * simple substring match with a `string` as described above. The special property name can be - * overwritten, using the `anyPropertyKey` parameter. - * The predicate can be negated by prefixing the string with `!`. - * For example `{name: "!M"}` predicate will return an array of items which have property `name` - * not containing "M". - * - * Note that a named property will match properties on the same level only, while the special - * `$` property will match properties on the same level or deeper. E.g. an array item like - * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but - * **will** be matched by `{$: 'John'}`. - * - * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters. - * The function is called for each element of the array, with the element, its index, and - * the entire array itself as arguments. - * - * The final result is an array of those elements that the predicate returned true for. - * - * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in - * determining if values retrieved using `expression` (when it is not a function) should be - * considered a match based on the expected value (from the filter expression) and actual - * value (from the object in the array). - * - * Can be one of: - * - * - `function(actual, expected)`: - * The function will be given the object value and the predicate value to compare and - * should return true if both values should be considered equal. - * - * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. - * This is essentially strict comparison of expected and actual. - * - * - `false`: A short hand for a function which will look for a substring match in a case - * insensitive way. Primitive values are converted to strings. Objects are not compared against - * primitives, unless they have a custom `toString` method (e.g. `Date` objects). - * - * - * Defaults to `false`. - * - * @param {string} [anyPropertyKey] The special property name that matches against any property. - * By default `$`. - * - * @example - - -

This is similar to the native Promise implementation from ES6, + * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * + * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are + * available yet. + * + * It can be used like so: + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * // perform some asynchronous operation, resolve or reject the promise when appropriate. + * return $q(function(resolve, reject) { + * setTimeout(function() { + * if (okToGreet(name)) { + * resolve('Hello, ' + name + '!'); + * } else { + * reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * }); + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }); + * ``` + * + * Note: progress/notify callbacks are not currently supported via the ES6-style interface. + * + * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. + * + * However, the more traditional CommonJS-style usage is still available, and documented below. + * + * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an + * interface for interacting with an object that represents the result of an action that is + * performed asynchronously, and may or may not be finished at any given point in time. + * + * From the perspective of dealing with error handling, deferred and promise APIs are to + * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * var deferred = $q.defer(); + * + * setTimeout(function() { + * deferred.notify('About to greet ' + name + '.'); + * + * if (okToGreet(name)) { + * deferred.resolve('Hello, ' + name + '!'); + * } else { + * deferred.reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * + * return deferred.promise; + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }, function(update) { + * alert('Got notification: ' + update); + * }); + * ``` + * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * ## The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * ## The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved + * with the value which is resolved in that promise using + * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). + * It also notifies via the return value of the `notifyCallback` method. The promise cannot be + * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback + * arguments are optional. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * ## Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * ## Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in AngularJS, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * ## Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

Its goal is to assist in writing code in a way that (a) is secure by default, and + * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * ### Overview + * + * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in + * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically + * run security checks on them (sanitizations, trusted URL resource, depending on context), or throw + * when it cannot guarantee the security of the result. That behavior depends strongly on contexts: + * HTML can be sanitized, but template URLs cannot, for instance. + * + * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: + * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it + * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and + * render the input as-is, you will need to mark it as trusted for that context before attempting + * to bind it. + * + * As of version 1.2, AngularJS ships with SCE enabled by default. + * + * ### In practice + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + *
+ * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV, which would + * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog + * articles, etc. via bindings. (HTML is just one example of a context where rendering user + * controlled input creates security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, AngularJS makes sure bindings go through that sanitization, or + * any similar validation process, unless there's a good reason to trust the given value in this + * context. That trust is formalized with a function call. This means that as a developer, you + * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, + * you just need to ensure the values you mark as trusted indeed are safe - because they were + * received from your server, sanitized by your library, etc. You can organize your codebase to + * help with this - perhaps allowing only the files in a specific directory to do this. + * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then + * becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * build the trusted versions of your values. + * + * ### How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as + * a way to enforce the required security context in your data sink. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs + * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, + * when binding without directives, AngularJS will understand the context of your bindings + * automatically. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ### Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, AngularJS only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either add them to the {@link ng.$sceDelegateProvider#trustedResourceUrlList + * trustedResourceUrlList} or {@link ng.$sce#trustAsResourceUrl wrap them} into trusted values. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ### This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (e.g. + * `
`) just works (remember to include the + * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available + * when binding untrusted values to `$sce.HTML` context. + * AngularJS provides an implementation in `angular-sanitize.js`, and if you + * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in + * your application. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#trustedResourceUrlList trusted resource URL list} and {@link + * ng.$sceDelegateProvider#bannedResourceUrlList banned resource URL list} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ### What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.MEDIA_URL` | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. | + * | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.| + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required.

The {@link $sceDelegateProvider#trustedResourceUrlList $sceDelegateProvider#trustedResourceUrlList()} and {@link $sceDelegateProvider#bannedResourceUrlList $sceDelegateProvider#bannedResourceUrlList()} can be used to restrict trusted origins for `RESOURCE_URL` | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * + *
+ * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their + * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}. + * + * **As of 1.7.0, this is no longer the case.** + * + * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL` + * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate` + * service evaluates the expressions. + *
+ * + * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs` + * functions aren't useful yet. This might evolve. + * + * ### Format of items in {@link ng.$sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList}/{@link ng.$sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList} + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * for matching resource URL lists. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ### Show me an example using SCE. + * + * + * + *

For demonstration purposes only! + * // Do not use in new projects or libraries. + * $sceProvider.enabled(false); + * }); + * ``` + * + */ + +function $SceProvider() { + var enabled = true; + + /** + * @ngdoc method + * @name $sceProvider#enabled + * @kind function + * + * @param {boolean=} value If provided, then enables/disables SCE application-wide. + * @return {boolean} True if SCE is enabled, false otherwise. + * + * @description + * Enables/disables SCE and returns the current value. + */ + this.enabled = function(value) { + if (arguments.length) { + enabled = !!value; + } + return enabled; + }; + + + /* Design notes on the default implementation for SCE. + * + * The API contract for the SCE delegate + * ------------------------------------- + * The SCE delegate object must provide the following 3 methods: + * + * - trustAs(contextEnum, value) + * This method is used to tell the SCE service that the provided value is OK to use in the + * contexts specified by contextEnum. It must return an object that will be accepted by + * getTrusted() for a compatible contextEnum and return this value. + * + * - valueOf(value) + * For values that were not produced by trustAs(), return them as is. For values that were + * produced by trustAs(), return the corresponding input value to trustAs. Basically, if + * trustAs is wrapping the given values into some type, this operation unwraps it when given + * such a value. + * + * - getTrusted(contextEnum, value) + * This function should return the value that is safe to use in the context specified by + * contextEnum or throw and exception otherwise. + * + * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be + * opaque or wrapped in some holder object.

In + * such a case, trustAs() would return the same object that was passed in. getTrusted() would + * return the same object passed in if it was found in the registry under a compatible context or + * throw an exception otherwise. An implementation might only wrap values some of the time based + * on some criteria. getTrusted() might return a value and not throw an exception for special + * constants or objects even if not wrapped. All such implementations fulfill this contract. + * + * + * A note on the inheritance model for SCE contexts + * ------------------------------------------------ + * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This + * is purely an implementation details. + * + * The contract is simply this: + * + * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) + * will also succeed. + * + * Inheritance happens to capture this in a natural way.

+ * **Note**: If the array contains objects that reference themselves, filtering is not possible. + *
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from + * `array`. + * + * Can be one of: + * + * - `string`: The string is used for matching against the contents of the `array`. All strings or + * objects with string properties in `array` that match this string will be returned. This also + * applies to nested object properties. + * The predicate can be negated by prefixing the string with `!`. + * + * - `Object`: A pattern object can be used to filter specific properties on objects contained + * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items + * which have property `name` containing "M" and property `phone` containing "1". A special + * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match + * against any property of the object or its nested object properties. That's equivalent to the + * simple substring match with a `string` as described above. The special property name can be + * overwritten, using the `anyPropertyKey` parameter. + * The predicate can be negated by prefixing the string with `!`. + * For example `{name: "!M"}` predicate will return an array of items which have property `name` + * not containing "M". + * + * Note that a named property will match properties on the same level only, while the special + * `$` property will match properties on the same level or deeper. E.g. an array item like + * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but + * **will** be matched by `{$: 'John'}`. + * + * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters. + * The function is called for each element of the array, with the element, its index, and + * the entire array itself as arguments. + * + * The final result is an array of those elements that the predicate returned true for. + * + * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in + * determining if values retrieved using `expression` (when it is not a function) should be + * considered a match based on the expected value (from the filter expression) and actual + * value (from the object in the array). + * + * Can be one of: + * + * - `function(actual, expected)`: + * The function will be given the object value and the predicate value to compare and + * should return true if both values should be considered equal. + * + * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. + * This is essentially strict comparison of expected and actual. + * + * - `false`: A short hand for a function which will look for a substring match in a case + * insensitive way. Primitive values are converted to strings. Objects are not compared against + * primitives, unless they have a custom `toString` method (e.g. `Date` objects). + * + * + * Defaults to `false`. + * + * @param {string} [anyPropertyKey] The special property name that matches against any property. + * By default `$`. + * + * @example + + +

The `expression` is evaluated against each item and the output is used + * for comparing with other items. + * + * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in + * ascending order. + * + * The comparison is done using the `comparator` function. If none is specified, a default, built-in + * comparator is used (see below for details - in a nutshell, it compares numbers numerically and + * strings alphabetically). + * + * ### Under the hood + * + * Ordering the specified `collection` happens in two phases: + * + * 1. All items are passed through the predicate (or predicates), and the returned values are saved + * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed + * through a predicate that extracts the value of the `label` property, would be transformed to: + * ``` + * { + * value: 'foo', + * type: 'string', + * index: ... + * } + * ``` + * **Note:** `null` values use `'null'` as their type. + * 2. The comparator function is used to sort the items, based on the derived values, types and + * indices. + * + * If you use a custom comparator, it will be called with pairs of objects of the form + * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal + * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the + * second, or `1` otherwise. + * + * In order to ensure that the sorting will be deterministic across platforms, if none of the + * specified predicates can distinguish between two items, `orderBy` will automatically introduce a + * dummy predicate that returns the item's index as `value`. + * (If you are using a custom comparator, make sure it can handle this predicate as well.) + * + * If a custom comparator still can't distinguish between two items, then they will be sorted based + * on their index using the built-in comparator. + * + * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted + * value for an item, `orderBy` will try to convert that object to a primitive value, before passing + * it to the comparator. The following rules govern the conversion: + * + * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be + * used instead.
+ * (If the object has a `valueOf()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that + * returns a primitive, its return value will be used instead.
+ * (If the object has a `toString()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 3. No conversion; the object itself is used. + * + * ### The default comparator + * + * The default, built-in comparator should be sufficient for most usecases. In short, it compares + * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to + * using their index in the original collection, sorts values of different types by type and puts + * `undefined` and `null` values at the end of the sorted list. + * + * More specifically, it follows these steps to determine the relative order of items: + * + * 1. If the compared values are of different types: + * - If one of the values is undefined, consider it "greater than" the other. + * - Else if one of the values is null, consider it "greater than" the other. + * - Else compare the types themselves alphabetically. + * 2. If both values are of type `string`, compare them alphabetically in a case- and + * locale-insensitive way. + * 3. If both values are objects, compare their indices instead. + * 4. Otherwise, return: + * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). + * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). + * - `1`, otherwise. + * + * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being + * saved as numbers and not strings. + * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than" + * any other value (with undefined "greater than" null). This effectively means that `null` + * and `undefined` values end up at the end of a list sorted in ascending order. + * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects. + * + * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. + * @param {(Function|string|Array.)=} expression - A predicate (or list of + * predicates) to be used by the comparator to determine the order of elements. + * + * Can be one of: + * + * - `Function`: A getter function. This function will be called with each item as argument and + * the return value will be used for sorting. + * - `string`: An AngularJS expression. This expression will be evaluated against each item and the + * result will be used for sorting. For example, use `'label'` to sort by a property called + * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` + * property.
+ * (The result of a constant expression is interpreted as a property name to be used for + * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a + * property called `special name`.)
+ * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, + * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, + * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. + * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the + * relative order of two items, the next predicate is used as a tie-breaker. + * + * **Note:** If the predicate is missing or empty then it defaults to `'+'`. + * + * @param {boolean=} reverse - If `true`, reverse the sorting order. + * @param {(Function)=} comparator - The comparator function used to determine the relative order of + * value pairs. If omitted, the built-in comparator will be used. + * + * @returns {Array} - The sorted array. + * + * + * @example + * ### Ordering a table with `ngRepeat` + * + * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by + * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means + * it defaults to the built-in comparator. + * + + +

Instead some javascript logic should be triggered + * to handle the form submission in an application-specific way. * - * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale - * (e.g. Sep 3, 2010 12:05:08 PM) - * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM) - * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale - * (e.g. Friday, September 3, 2010) - * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010) - * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010) - * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10) - * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM) - * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM) + * For this reason, AngularJS prevents the default action (form submission to the server) unless the + * `` element has an `action` attribute specified. * - * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g. - * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence - * (e.g. `"h 'o''clock'"`). + * You can use one of the following two ways to specify what javascript method should be called when + * a form is submitted: * - * Any other characters in the `format` string will be output as-is. + * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element + * - {@link ng.directive:ngClick ngClick} directive on the first + * button or input field of type submit (input[type=submit]) * - * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or - * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its - * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is - * specified in the string input, the time is considered to be in the local timezone. - * @param {string=} format Formatting rules (see Description). If not specified, - * `mediumDate` is used. - * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the - * continental US time zone abbreviations, but for general use, use a time zone offset, for - * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian) - * If not specified, the timezone of the browser will be used. - * @returns {string} Formatted string or the input if input is not recognized as date/millis. + * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} + * or {@link ng.directive:ngClick ngClick} directives. + * This is because of the following form submission rules in the HTML specification: + * + * - If a form has only one input field then hitting enter in this field triggers form submit + * (`ngSubmit`) + * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter + * doesn't trigger submit + * - if a form has one or more input fields and one or more buttons or input[type=submit] then + * hitting enter in any of the input fields will trigger the click handler on the *first* button or + * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) + * + * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is + * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * @animations + * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. + * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any + * other validations that are performed within the form. Animations in ngForm are similar to how + * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well + * as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style a form element + * that has been rendered as invalid after it has been validated: + * + * 
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-form {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-form.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }

The `expression` is evaluated against each item and the output is used - * for comparing with other items. - * - * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in - * ascending order. - * - * The comparison is done using the `comparator` function. If none is specified, a default, built-in - * comparator is used (see below for details - in a nutshell, it compares numbers numerically and - * strings alphabetically). - * - * ### Under the hood - * - * Ordering the specified `collection` happens in two phases: - * - * 1. All items are passed through the predicate (or predicates), and the returned values are saved - * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed - * through a predicate that extracts the value of the `label` property, would be transformed to: - * ``` - * { - * value: 'foo', - * type: 'string', - * index: ... - * } - * ``` - * **Note:** `null` values use `'null'` as their type. - * 2. The comparator function is used to sort the items, based on the derived values, types and - * indices. - * - * If you use a custom comparator, it will be called with pairs of objects of the form - * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal - * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the - * second, or `1` otherwise. - * - * In order to ensure that the sorting will be deterministic across platforms, if none of the - * specified predicates can distinguish between two items, `orderBy` will automatically introduce a - * dummy predicate that returns the item's index as `value`. - * (If you are using a custom comparator, make sure it can handle this predicate as well.) - * - * If a custom comparator still can't distinguish between two items, then they will be sorted based - * on their index using the built-in comparator. - * - * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted - * value for an item, `orderBy` will try to convert that object to a primitive value, before passing - * it to the comparator. The following rules govern the conversion: - * - * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be - * used instead.
- * (If the object has a `valueOf()` method that returns another object, then the returned object - * will be used in subsequent steps.) - * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that - * returns a primitive, its return value will be used instead.
- * (If the object has a `toString()` method that returns another object, then the returned object - * will be used in subsequent steps.) - * 3. No conversion; the object itself is used. - * - * ### The default comparator - * - * The default, built-in comparator should be sufficient for most usecases. In short, it compares - * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to - * using their index in the original collection, sorts values of different types by type and puts - * `undefined` and `null` values at the end of the sorted list. - * - * More specifically, it follows these steps to determine the relative order of items: - * - * 1. If the compared values are of different types: - * - If one of the values is undefined, consider it "greater than" the other. - * - Else if one of the values is null, consider it "greater than" the other. - * - Else compare the types themselves alphabetically. - * 2. If both values are of type `string`, compare them alphabetically in a case- and - * locale-insensitive way. - * 3. If both values are objects, compare their indices instead. - * 4. Otherwise, return: - * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). - * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). - * - `1`, otherwise. - * - * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being - * saved as numbers and not strings. - * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than" - * any other value (with undefined "greater than" null). This effectively means that `null` - * and `undefined` values end up at the end of a list sorted in ascending order. - * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects. - * - * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. - * @param {(Function|string|Array.)=} expression - A predicate (or list of - * predicates) to be used by the comparator to determine the order of elements. - * - * Can be one of: - * - * - `Function`: A getter function. This function will be called with each item as argument and - * the return value will be used for sorting. - * - `string`: An AngularJS expression. This expression will be evaluated against each item and the - * result will be used for sorting. For example, use `'label'` to sort by a property called - * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` - * property.
- * (The result of a constant expression is interpreted as a property name to be used for - * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a - * property called `special name`.)
- * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, - * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, - * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. - * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the - * relative order of two items, the next predicate is used as a tie-breaker. - * - * **Note:** If the predicate is missing or empty then it defaults to `'+'`. - * - * @param {boolean=} reverse - If `true`, reverse the sorting order. - * @param {(Function)=} comparator - The comparator function used to determine the relative order of - * value pairs. If omitted, the built-in comparator will be used. - * - * @returns {Array} - The sorted array. - * - * - * @example - * ### Ordering a table with `ngRepeat` - * - * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by - * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means - * it defaults to the built-in comparator. - * - - -

+ * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the + * value of their `name` attribute to determine the property under which their + * {@link ngModel.NgModelController NgModelController} will be published on the parent + * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple + * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be + * published on the parent `FormController` under that name. The rest of the controllers will + * continue to work as expected, but you won't be able to access them as properties on the parent + * `FormController`. + * + *
+ *

+ * In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so + * that the browser can manage their state (checked/unchecked) based on the state of other + * inputs in the same group. + *

+ *

+ * In AngularJS forms, this is not necessary. The input's state will be updated based on the + * value of the underlying model data. + *

+ *

Model binding, + * validation and number parsing are nevertheless supported. + * + * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]` + * in a way that never allows the input to hold an invalid value. That means: + * - any non-numerical value is set to `(max + min) / 2`. + * - any numerical value that is less than the current min val, or greater than the current max val + * is set to the min / max val respectively. + * - additionally, the current `step` is respected, so the nearest value that satisfies a step + * is used. + * + * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range)) + * for more info. + * + * This has the following consequences for AngularJS: + * + * Since the element value should always reflect the current model value, a range input + * will set the bound ngModel expression to the value that the browser has set for the + * input element. For example, in the following input ``, + * if the application sets `model.value = null`, the browser will set the input to `'50'`. + * AngularJS will then set the model to `50`, to prevent input and model value being out of sync. + * + * That means the model for range will immediately be set to `50` after `ngModel` has been + * initialized. It also means a range input can never have the required error. + * + * This does not only affect changes to the model value, but also to the values of the `min`, + * `max`, and `step` attributes. When these change in a way that will cause the browser to modify + * the input value, AngularJS will also update the model value. + * + * Automatic value adjustment also means that a range input element can never have the `required`, + * `min`, or `max` errors. + * + * However, `step` is currently only fully implemented by Firefox. Other browsers have problems + * when the step value changes dynamically - they do not adjust the element value correctly, but + * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step` + * error on the input, and set the model to `undefined`. + * + * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do + * not set the `min` and `max` attributes, which means that the browser won't automatically adjust + * the input value based on their values, and will always assume min = 0, max = 100, and step = 1. + * + * @param {string} ngModel Assignable AngularJS expression to data-bind to. + * @param {string=} name Property name of the form under which the control is published. + * @param {string=} min Sets the `min` validation to ensure that the value entered is greater + * than `min`.
