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. + * + * <example name="doCheckDateExample" module="do-check-module"> + * <file name="app.js"> + * angular.module('do-check-module', []) + * .component('app', { + * template: + * 'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' + + * 'Date: {{ $ctrl.date }}' + + * '<test date="$ctrl.date"></test>', + * controller: function() { + * this.date = new Date(); + * this.month = this.date.getMonth(); + * this.updateDate = function() { + * this.date.setMonth(this.month); + * }; + * } + * }) + * .component('test', { + * bindings: { date: '<' }, + * template: + * '<pre>{{ $ctrl.log | json }}</pre>', + * controller: function() { + * var previousValue; + * this.log = []; + * this.$doCheck = function() { + * var currentValue = this.date && this.date.valueOf(); + * if (previousValue !== currentValue) { + * this.log.push('doCheck: date mutated: ' + this.date); + * previousValue = currentValue; + * } + * }; + * } + * }); + * </file> + * <file name="index.html"> + * <app></app> + * </file> + * </example> + * + * 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.) + * + * <example name="doCheckArrayExample" module="do-check-module"> + * <file name="index.html"> + * <div ng-init="items = []"> + * <button ng-click="items.push(items.length)">Add Item</button> + * <button ng-click="items = []">Reset Items</button> + * <pre>{{ items }}</pre> + * <test items="items"></test> + * </div> + * </file> + * <file name="app.js"> + * angular.module('do-check-module', []) + * .component('test', { + * bindings: { items: '<' }, + * template: + * '<pre>{{ $ctrl.log | json }}</pre>', + * controller: function() { + * this.log = []; + * + * this.$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); + * } + * }; + * } + * }); + * </file> + * </example> + * + * + * ### 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 `<my-component + * my-attr="hello {{name}}">` 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 `<my-component my-attr="parentModel">` 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 + * `$watchCollection`}: use `=*` or `=*attr` + * + * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an + * expression passed via the attribute `attr`. The expression is evaluated in the context of the + * parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the + * local name. + * + * For example, given `<my-component my-attr="parentModel">` and directive definition of + * `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the + * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected + * in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however + * two caveats: + * 1. one-way binding does not copy the value from the parent to the isolate scope, it simply + * sets the same value. That means if your bound value is an object, changes to its properties + * in the isolated scope will be reflected in the parent scope (because both reference the same object). + * 2. one-way binding watches changes to the **identity** of the parent value. That means the + * {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference + * to the value has changed. In most cases, this should not be of concern, but can be important + * to know if you one-way bind to an object, and then replace that object in the isolated scope. + * If you now change a property of the object in your parent scope, the change will not be + * propagated to the isolated scope, because the identity of the object on the parent scope + * has not changed. Instead you must assign a new object. + * + * One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings + * back to the parent. However, it does not make this completely impossible. + * + * By default, the {@link ng.$rootScope.Scope#$watch `$watch`} + * method is used for tracking changes, and the equality check is based on object identity. + * It's also possible to watch the evaluated value shallowly with + * {@link ng.$rootScope.Scope#$watchCollection `$watchCollection`}: use `<*` or `<*attr` + * + * * `&` or `&attr` - provides a way to execute an expression 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 `<my-component my-attr="count = count + value">` 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 + } + } + } + }) + *``` + * + * + * ##### Combining directives with different scope defintions + * + * In general it's possible to apply more than one directive to one element, but there might be limitations + * depending on the type of scope required by the directives. 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. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkingFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like `<svg>`). + * * See also the `directive.templateNamespace` property. + * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) + * then the default transclusion is provided. + * The `$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): `<my-directive></my-directive>` + * * `A` - Attribute (default): `<div my-directive="exp"></div>` + * * `C` - Class: `<div class="my-directive: exp;"></div>` + * * `M` - Comment: `<!-- directive: my-directive exp -->` + * + * + * #### `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 `<svg>` and `<math>`. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `<svg>` or `<math>`. + * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`). + * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`). + * + * 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 `<div red-on-hover>{{delete_str}}</div>`. + * * 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` + * <div class="alert alert-danger"> + * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+). + * </div> + * + * Specifies what the template should replace. Defaults to `false`. + * + * * `true` - the template will replace the directive's element. + * * `false` - the template will replace the contents of the directive's element. + * + * The replacement process migrates all of the attributes / classes from the old element to the new + * one. See the {@link guide/directive#template-expanding-directive + * Directives Guide} for an example. + * + * There are very few scenarios where element replacement is required for the application function, + * the main one being reusable custom components that are used within SVG contexts + * (because SVG doesn't work with custom elements in the DOM tree). + * + * #### `transclude` + * Extract the contents of the element where the directive appears and make it available to the directive. + * The contents are compiled and provided to the directive as a **transclusion function**. See the + * {@link $compile#transclusion Transclusion} section below. + * + * + * #### `compile` + * + * ```js + * function compile(tElement, tAttrs, transclude) { ... } + * ``` + * + * The compile function deals with transforming the template DOM. Since most directives do not do + * template transformation, it is not used often. The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared. It is + * safe to do template transformation on the element and child elements only. + * + * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared + * between all directive compile functions. + * + * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` + * + * <div class="alert alert-warning"> + * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + * </div> + + * <div class="alert alert-warning"> + * **Note:** The compile function cannot handle directives that recursively use themselves in their + * own templates or compile functions. Compiling these directives results in an infinite loop and + * stack overflow errors. + * + * This can be avoided by manually using `$compile` in the postLink function to imperatively compile + * a directive's template instead of relying on automatic template compilation via `template` or + * `templateUrl` declaration or manual compilation inside the compile function. + * </div> + * + * <div class="alert alert-danger"> + * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it + * e.g. does not know about the right outer scope. Please use the transclude function that is passed + * to the link function instead. + * </div> + + * A compile function can have a return value which can be either a function or an object. + * + * * returning a (post-link) function - is equivalent to registering the linking function via the + * `link` property of the config object when the compile function is empty. + * + * * returning an object with function(s) registered via `pre` and `post` properties - allows you to + * control when a linking function should be called during the linking phase. See info about + * pre-linking and post-linking functions below. + * + * + * #### `link` + * This property is used only if the `compile` property is not defined. + * + * ```js + * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } + * ``` + * + * The link function is responsible for registering DOM listeners as well as updating the DOM. It is + * executed after the template has been cloned. This is where most of the directive logic will be + * put. + * + * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the + * directive for registering {@link ng.$rootScope.Scope#$watch watches}. + * + * * `iElement` - instance element - The element where the directive is to be used. It is safe to + * manipulate the children of the element only in `postLink` function since the children have + * already been linked. + * + * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared + * between all directive linking functions. + * + * * `controller` - the directive's required controller instance(s) - Instances are shared + * among all directives, which allows the directives to use the controllers as a communication + * channel. The exact value depends on the directive's `require` property: + * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one + * * `string`: the controller instance + * * `array`: array of controller instances + * + * If a required controller cannot be found, and it is optional, the instance is `null`, + * otherwise the {@link error:$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. + * + * <div class="alert alert-warning"> + * **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}. + * </div> + * + * 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 `<my-custom-element>` 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. + * + * <div class="alert alert-info"> + * 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. + * </div> + * + * 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. + * + * <div class="alert alert-info"> + * **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. + * </div> + * + * 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(); + * ``` + * + * <div class="alert alert-info"> + * **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 `$destroy` on the transclusion scope. + * </div> + * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transcluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + * <div ng-app> + * <div isolate> + * <div transclusion> + * </div> + * </div> + * </div> + * ``` + * + * The `$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.$observe('ngModel', function(value) { + * console.log('ngModel has changed value to ' + value); + * }); + * } + * ``` + * + * ## Example + * + * <div class="alert alert-warning"> + * **Note**: Typically directives are registered with `module.directive`. The example below is + * to illustrate how `$compile` works. + * </div> + * + <example module="compileExample" name="compile"> + <file name="index.html"> + <script> + angular.module('compileExample', [], function($compileProvider) { + // Configure new 'compile' directive by passing a directive + // factory function.

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('<p>{{total}}</p>'); + * 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.

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}.

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): + * - <code>Accept: application/json, text/plain, \*/\*</code> + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$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' } + * } + * + * $http(req).then(function(){...}, function(){...}); + * ``` + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + * <div class="alert alert-warning"> + * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. + * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). + * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest + * function will be reflected on the scope and in any templates where the object is data-bound. + * To prevent this, transform functions should have no side-effects. + * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. + * </div> + * + * ### Default Transformations + * + * The `$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 $httpProvider.xsrfTrustedOrigins} for + * more details. + * + * <div class="alert alert-danger"> + * **Warning**<br /> + * Only trusted origins that you have control over and make sure you understand the + * implications of doing so. + * </div> + * + * The name of the cookie and the header can be specified using the `xsrfCookieName` and + * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time, + * `$http.defaults` at run-time, or the per-request config object. + * + * In order to prevent collisions in environments where multiple AngularJS apps share the + * same domain or subdomain, we recommend that each application uses a unique cookie name. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested; + * or an object created by a call to `$sce.trustAsResourceUrl(url)`. + * - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized + * with the `paramSerializer` and appended as GET parameters. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server.

Start and end markers + * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash). + * It will be rendered as a regular start/end marker, and will not be interpreted as an expression + * or binding. + * + * This enables web-servers to prevent script injection attacks and defacing attacks, to some + * degree, while also enabling code examples to work without relying on the + * {@link ng.directive:ngNonBindable ngNonBindable} directive. + * + * **For security purposes, it is strongly encouraged that web servers escape user-supplied data, + * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all + * interpolation start/end markers with their escaped counterparts.** + * + * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered + * output when the $interpolate service processes the text. So, for HTML elements interpolated + * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter + * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, + * this is typically useful only when user-data is used in rendering a template from the server, or + * when otherwise untrusted data is used by a directive. + * + * <example name="interpolation"> + * <file name="index.html"> + * <div ng-init="username='A user'"> + * <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\} + * </p> + * <p><strong>{{username}}</strong> attempts to inject code which will deface the + * application, but fails to accomplish their task, because the server has correctly + * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash) + * characters.</p> + * <p>Instead, the result of the attempted script injection is visible, and can be removed + * from the database by an administrator.</p> + * </div> + * </file> + * </example> + * + * @knownIssue + * It is currently not possible for an interpolated expression to contain the interpolation end + * symbol. 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: + * + * ``` + * <div data-context='{"context":{"id":3,"type":"page"}}"> + * ``` + * + * The workaround is to ensure that such instances are separated by whitespace: + * ``` + * <div data-context='{"context":{"id":3,"type":"page"} }"> + * ``` + * + * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information. + * + * @param {string} text The text with markup to interpolate. + * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have + * embedded expression in order to return an interpolation function.

AngularJS makes use of this in the {@link $parse} service to + * provide a 30% increase in the speed of evaluating AngularJS expressions. (This CSP rule can be + * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would + * weaken the protections offered by CSP.) + * + * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden. + * This prevents apps from injecting custom styles directly into the document. AngularJS makes use of + * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these + * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css` + * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but + * it is generally not recommended as it would weaken the protections offered by CSP.) + * + * If you do not provide `ngCsp` then AngularJS tries to autodetect if CSP is blocking dynamic code + * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically + * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a + * CSP error to be logged in the console: + * + * ``` + * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of + * script in the following Content Security Policy directive: "default-src 'self'". Note that + * 'script-src' was not explicitly set, so 'default-src' is used as a fallback. + * ``` + * + * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp` + * directive on an element of the HTML document that appears before the `<script>` tag that loads + * the `angular.js` file. + * + * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.* + * + * You can specify which of the CSP related AngularJS features should be deactivated by providing + * a value for the `ng-csp` attribute. The options are as follows: + * + * * no-inline-style: this stops AngularJS from injecting CSS styles into the DOM + * + * * no-unsafe-eval: this stops AngularJS from optimizing $parse with unsafe eval of strings + * + * You can use these values in the following combinations: + * + * + * * No declaration means that AngularJS will assume that you can do inline styles, but it will do + * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous + * versions of AngularJS. + * + * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell AngularJS to deactivate both inline + * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous + * versions of AngularJS. + * + * * Specifying only `no-unsafe-eval` tells AngularJS that we must not use eval, but that we can + * inject inline styles.

If the expression assigned to `ngIf` evaluates to a false + * value then the element is removed from the DOM, otherwise a clone of the + * element is reinserted into the DOM. + * + * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the + * element in the DOM rather than changing its visibility via the `display` css property. A common + * case when this difference is significant is when using css selectors that rely on an element's + * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes. + * + * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope + * is created when the element is restored. The scope created within `ngIf` inherits from + * its parent scope using + * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance). + * An important implication of this is if `ngModel` is used within `ngIf` to bind to + * a javascript primitive defined in the parent scope. In this case any modifications made to the + * variable within the child scope will override (hide) the value in the parent scope. + * + * Also, `ngIf` recreates elements using their compiled state. An example of this behavior + * is if an element's class attribute is directly modified after it's compiled, using something like + * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element + * the added class will be lost because the original compiled state is used to regenerate the element. + * + * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter` + * and `leave` effects. + * + * @animations + * | Animation | Occurs | + * |----------------------------------|-------------------------------------| + * | {@link ng.$animate#enter enter} | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container | + * | {@link ng.$animate#leave leave} | just before the `ngIf` contents are removed from the DOM | + * + * @element ANY + * @scope + * @priority 600 + * @param {expression} ngIf If the {@link guide/expression expression} is falsy then + * the element is removed from the DOM tree.

This is important to know when + * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the + * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered. + * + * The model must be assigned an entirely new object or collection before a re-rendering will occur. + * + * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression + * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or + * if the select is given the `multiple` attribute. + * + * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the + * first level of the object (or only changing the properties of an item in the collection if it's an array) will still + * not trigger a re-rendering of the model. + * + * ## CSS classes + * The following CSS classes are added and removed on the associated input/select/textarea element + * depending on the validity of the model. + * + * - `ng-valid`: the model is valid + * - `ng-invalid`: the model is invalid + * - `ng-valid-[key]`: for each valid key added by `$setValidity` + * - `ng-invalid-[key]`: for each invalid key added by `$setValidity` + * - `ng-pristine`: the control hasn't been interacted with yet + * - `ng-dirty`: the control has been interacted with + * - `ng-touched`: the control has been blurred + * - `ng-untouched`: the control hasn't been blurred + * - `ng-pending`: any `$asyncValidators` are unfulfilled + * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined + * by the {@link ngModel.NgModelController#$isEmpty} method + * - `ng-not-empty`: the view contains a non-empty value + * + * Keep in mind that ngAnimate can detect each of these classes when added and removed. + * + * @animations + * Animations within models are triggered when any of the associated CSS classes are added and removed + * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`, + * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself. + * The animations that are triggered within ngModel 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 an input element + * that has been rendered as invalid after it has been validated: + * + * <pre> + * //be sure to include ngAnimate as a module to hook into more + * //advanced animations + * .my-input { + * transition:0.5s linear all; + * background: white; + * } + * .my-input.ng-invalid { + * background: red; + * color:white; + * } + * </pre> + * + * @example + * ### Basic Usage + * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model"> + <file name="index.html"> + <script> + angular.module('inputExample', []) + .controller('ExampleController', ['$scope', function($scope) { + $scope.val = '1'; + }]); + </script> + <style> + .my-input { + transition:all linear 0.5s; + background: transparent; + } + .my-input.ng-invalid { + color:white; + background: red; + } + </style> + <p id="inputDescription"> + Update input to see transitions when valid/invalid. + Integer is a valid value. + </p> + <form name="testForm" ng-controller="ExampleController"> + <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input" + aria-describedby="inputDescription" /> + </form> + </file> + * </example> + * + * @example + * ### Binding to a getter/setter + * + * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a + * function that returns a representation of the model when called with zero arguments, and sets + * the internal state of a model when called with an argument.

You can specify an `ngModelOptions` directive on any element. All {@link ngModel} + * directives will use the options of their nearest `ngModelOptions` ancestor. + * + * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as + * an AngularJS expression. This expression should evaluate to an object, whose properties contain + * the settings. For example: `<div ng-model-options="{ debounce: 100 }"`. + * + * ## Inheriting Options + * + * You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions` + * directive by giving it the value of `"$inherit"`. + * Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the + * DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings + * will be used. + * + * For example given the following fragment of HTML + * + * + * ```html + * <div ng-model-options="{ allowInvalid: true, debounce: 200 }"> + * <form ng-model-options="{ updateOn: 'blur', allowInvalid: '$inherit' }"> + * <input ng-model-options="{ updateOn: 'default', allowInvalid: '$inherit' }" /> + * </form> + * </div> + * ``` + * + * the `input` element will have the following settings + * + * ```js + * { allowInvalid: true, updateOn: 'default', debounce: 0 } + * ``` + * + * Notice that the `debounce` setting was not inherited and used the default value instead. + * + * You can specify that all undefined settings are automatically inherited from an ancestor by + * including a property with key of `"*"` and value of `"$inherit"`. + * + * For example given the following fragment of HTML + * + * + * ```html + * <div ng-model-options="{ allowInvalid: true, debounce: 200 }"> + * <form ng-model-options="{ updateOn: 'blur', "*": '$inherit' }"> + * <input ng-model-options="{ updateOn: 'default', "*": '$inherit' }" /> + * </form> + * </div> + * ``` + * + * the `input` element will have the following settings + * + * ```js + * { allowInvalid: true, updateOn: 'default', debounce: 200 } + * ``` + * + * Notice that the `debounce` setting now inherits the value from the outer `<div>` element. + * + * If you are creating a reusable component then you should be careful when using `"*": "$inherit"` + * since you may inadvertently inherit a setting in the future that changes the behavior of your component. + * + * + * ## Triggering and debouncing model updates + * + * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will + * trigger a model update and/or a debouncing delay so that the actual update only takes place when + * a timer expires; this timer will be reset after another change takes place. + * + * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might + * be different from the value in the actual model. This means that if you update the model you + * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in + * order to make sure it is synchronized with the model and that any debounced action is canceled. + * + * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue} + * method is by making sure the input is placed inside a form that has a `name` attribute. This is + * important because `form` controllers are published to the related scope under the name in their + * `name` attribute. + * + * Any pending changes will take place immediately when an enclosing form is submitted via the + * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * ### Overriding immediate updates + * + * The following example shows how to override immediate updates. Changes on the inputs within the + * form will update the model only when the control loses focus (blur event). If `escape` key is + * pressed while the input field is focused, the value is reset to the value in the current model. + * + * <example name="ngModelOptions-directive-blur" module="optionsExample"> + * <file name="index.html"> + * <div ng-controller="ExampleController"> + * <form name="userForm"> + * <label> + * Name: + * <input type="text" name="userName" + * ng-model="user.name" + * ng-model-options="{ updateOn: 'blur' }" + * ng-keyup="cancel($event)" /> + * </label><br /> + * <label> + * Other data: + * <input type="text" ng-model="user.data" /> + * </label><br /> + * </form> + * <pre>user.name = <span ng-bind="user.name"></span></pre> + * </div> + * </file> + * <file name="app.js"> + * angular.module('optionsExample', []) + * .controller('ExampleController', ['$scope', function($scope) { + * $scope.user = { name: 'say', data: '' }; + * + * $scope.cancel = function(e) { + * if (e.keyCode === 27) { + * $scope.userForm.userName.$rollbackViewValue(); + * } + * }; + * }]); + * </file> + * <file name="protractor.js" type="protractor"> + * var model = element(by.binding('user.name')); + * var input = element(by.model('user.name')); + * var other = element(by.model('user.data')); + * + * it('should allow custom events', function() { + * input.sendKeys(' hello'); + * input.click(); + * expect(model.getText()).toEqual('say'); + * other.click(); + * expect(model.getText()).toEqual('say hello'); + * }); + * + * it('should $rollbackViewValue when model changes', function() { + * input.sendKeys(' hello'); + * expect(input.getAttribute('value')).toEqual('say hello'); + * input.sendKeys(protractor.Key.ESCAPE); + * expect(input.getAttribute('value')).toEqual('say'); + * other.click(); + * expect(model.getText()).toEqual('say'); + * }); + * </file> + * </example> + * + * ### Debouncing updates + * + * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change. + * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty. + * + * <example name="ngModelOptions-directive-debounce" module="optionsExample"> + * <file name="index.html"> + * <div ng-controller="ExampleController"> + * <form name="userForm"> + * Name: + * <input type="text" name="userName" + * ng-model="user.name" + * ng-model-options="{ debounce: 1000 }" /> + * <button ng-click="userForm.userName.$rollbackViewValue(); user.name=''">Clear</button><br /> + * </form> + * <pre>user.name = <span ng-bind="user.name"></span></pre> + * </div> + * </file> + * <file name="app.js"> + * angular.module('optionsExample', []) + * .controller('ExampleController', ['$scope', function($scope) { + * $scope.user = { name: 'say' }; + * }]); + * </file> + * </example> + * + * ### Default events, extra triggers, and catch-all debounce values + * + * This example shows the relationship between "default" update events and + * additional `updateOn` triggers. + * + * `default` events are those that are bound to the control, and when fired, update the `$viewValue` + * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed + * in `updateOn` is considered a "default" event, since different control types have different + * default events. + * + * The control in this example updates by "default", "click", and "blur", with different `debounce` + * values. You can see that "click" doesn't have an individual `debounce` value - + * therefore it uses the `*` debounce value. + * + * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue} + * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list, + * it is considered a "default" event and will update the + * control if "default" is defined in `updateOn`, and will receive the "default" debounce value. + * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`. + * + * You can change the `updateOn` and `debounce` configuration to test different scenarios. This + * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}. + * + <example name="ngModelOptions-advanced" module="optionsExample"> + <file name="index.html"> + <model-update-demo></model-update-demo> + </file> + <file name="app.js"> + angular.module('optionsExample', []) + .component('modelUpdateDemo', { + templateUrl: 'template.html', + controller: function() { + this.name = 'Chinua'; + + this.options = { + updateOn: 'default blur click', + debounce: { + default: 2000, + blur: 0, + '*': 1000 + } + }; + + this.updateEvents = function() { + var eventList = this.options.updateOn.split(' '); + eventList.push('*'); + var events = {}; + + for (var i = 0; i < eventList.length; i++) { + events[eventList[i]] = this.options.debounce[eventList[i]]; + } + + this.events = events; + }; + + this.updateOptions = function() { + var options = angular.extend(this.options, { + updateOn: Object.keys(this.events).join(' ').replace('*', ''), + debounce: this.events + }); + + this.form.input.$overrideModelOptions(options); + }; + + // Initialize the event form + this.updateEvents(); + } + }); + </file> + <file name="template.html"> + <form name="$ctrl.form"> + Input: <input type="text" name="input" ng-model="$ctrl.name" ng-model-options="$ctrl.options" /> + </form> + Model: <tt>{{$ctrl.name}}</tt> + <hr> + <button ng-click="$ctrl.form.input.$setViewValue('some value', 'custom')">Trigger setViewValue with 'some value' and 'custom' event</button> + + <hr> + <form ng-submit="$ctrl.updateOptions()"> + <b>updateOn</b><br> + <input type="text" ng-model="$ctrl.options.updateOn" ng-change="$ctrl.updateEvents()" ng-model-options="{debounce: 500}"> + + <table> + <tr> + <th>Option</th> + <th>Debounce value</th> + </tr> + <tr ng-repeat="(key, value) in $ctrl.events"> + <td>{{key}}</td> + <td><input type="number" ng-model="$ctrl.events[key]" /></td> + </tr> + </table> + + <br> + <input type="submit" value="Update options"> + </form> + </file> + </example> + * + * + * ## Model updates and validation + * + * The default behaviour in `ngModel` is that the model value is set to `undefined` when the + * validation determines that the value is invalid. By setting the `allowInvalid` property to true, + * the model will still be updated even if the value is invalid. + * + * + * ## Connecting to the scope + * + * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression + * on the scope refers to a "getter/setter" function rather than the value itself. + * + * The following example shows how to bind to getter/setters: + * + * <example name="ngModelOptions-directive-getter-setter" module="getterSetterExample"> + * <file name="index.html"> + * <div ng-controller="ExampleController"> + * <form name="userForm"> + * <label> + * Name: + * <input type="text" name="userName" + * ng-model="user.name" + * ng-model-options="{ getterSetter: true }" /> + * </label> + * </form> + * <pre>user.name = <span ng-bind="user.name()"></span></pre> + * </div> + * </file> + * <file name="app.js"> + * angular.module('getterSetterExample', []) + * .controller('ExampleController', ['$scope', function($scope) { + * var _name = 'Brian'; + * $scope.user = { + * name: function(newName) { + * return angular.isDefined(newName) ? (_name = newName) : _name; + * } + * }; + * }]); + * </file> + * </example> + * + * + * ## Programmatically changing options + * + * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not + * watched for changes. However, it is possible to override the options on a single + * {@link ngModel.NgModelController} instance with + * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}. + * See also the example for + * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values + * Default events, extra triggers, and catch-all debounce values}. + * + * + * ## Specifying timezones + * + * You can specify the timezone that date/time input directives expect by providing its name in the + * `timezone` property. + * + * + * ## Formatting the value of `time` and `datetime-local` + * + * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value + * that is displayed in the control. Note that browsers may apply their own formatting + * in the user interface. + * + <example name="ngModelOptions-time-format" module="timeExample"> + <file name="index.html"> + <time-example></time-example> + </file> + <file name="script.js"> + angular.module('timeExample', []) + .component('timeExample', { + templateUrl: 'timeExample.html', + controller: function() { + this.time = new Date(1970, 0, 1, 14, 57, 0); + + this.options = { + timeSecondsFormat: 'ss', + timeStripZeroSeconds: true + }; + + this.optionChange = function() { + this.timeForm.timeFormatted.$overrideModelOptions(this.options); + this.time = new Date(this.time); + }; + } + }); + </file> + <file name="timeExample.html"> + <form name="$ctrl.timeForm"> + <strong>Default</strong>: + <input type="time" ng-model="$ctrl.time" step="any" /><br> + <strong>With options</strong>: + <input type="time" name="timeFormatted" ng-model="$ctrl.time" step="any" ng-model-options="$ctrl.options" /> + <br> + + Options:<br> + <code>timeSecondsFormat</code>: + <input + type="text" + ng-model="$ctrl.options.timeSecondsFormat" + ng-change="$ctrl.optionChange()"> + <br> + <code>timeStripZeroSeconds</code>: + <input + type="checkbox" + ng-model="$ctrl.options.timeStripZeroSeconds" + ng-change="$ctrl.optionChange()"> + </form> + </file> + * </example> + * + * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and + * and its descendents. + * + * **General options**: + * + * - `updateOn`: string specifying which event should the input be bound to. You can set several + * events using an space delimited list. There is a special event called `default` that + * matches the default events belonging to the control. These are the events that are bound to + * the control, and when fired, update the `$viewValue` via `$setViewValue`. + * + * `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event, + * since different control types use different default events. + * + * See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates + * Triggering and debouncing model updates}. + * + * - `debounce`: integer value which contains the debounce model update value in milliseconds. A + * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a + * custom value for each event. For example: + * ``` + * ng-model-options="{ + * updateOn: 'default blur', + * debounce: { 'default': 500, 'blur': 0 } + * }" + * ``` + * You can use the `*` key to specify a debounce value that applies to all events that are not + * specifically listed. In the following example, `mouseup` would have a debounce delay of 1000: + * ``` + * ng-model-options="{ + * updateOn: 'default blur mouseup', + * debounce: { 'default': 500, 'blur': 0, '*': 1000 } + * }" + * ``` + * - `allowInvalid`: boolean value which indicates that the model can be set with values that did + * not validate correctly instead of the default behavior of setting the model to undefined. + * - `getterSetter`: boolean value which determines whether or not to treat functions bound to + * `ngModel` as getters/setters. + * + * + * **Input-type specific options**: + * + * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for + * `<input type="date" />`, `<input type="time" />`, ... . 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. + * Note that changing the timezone will have no effect on the current date, and is only applied after + * the next input / model change. + * + * - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and + * milliseconds. The option follows the format string of {@link date date filter}. + * By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds). + * The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both + * seconds and milliseconds. + * Note that browsers that support `time` and `datetime-local` require the hour and minutes + * part of the time string, and may show the value differently in the user interface. + * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}. + * + * - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the + * seconds and milliseconds from the formatted value if they are zero. This option is applied + * after `timeSecondsFormat`. + * This option can be used to make the formatting consistent over different browsers, as some + * browsers with support for `time` will natively hide the milliseconds and + * seconds if they are zero, but others won't, and browsers that don't implement these input + * types will always show the full string. + * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}. + * + */ +var ngModelOptionsDirective = function() { + NgModelOptionsController.$inject = ['$attrs', '$scope']; + function NgModelOptionsController($attrs, $scope) { + this.$$attrs = $attrs; + this.$$scope = $scope; + } + NgModelOptionsController.prototype = { + $onInit: function() { + var parentOptions = this.parentCtrl ? this.parentCtrl.$options : defaultModelOptions; + var modelOptionsDefinition = this.$$scope.$eval(this.$$attrs.ngModelOptions); + + this.$options = parentOptions.createChild(modelOptionsDefinition); + } + }; + + return { + restrict: 'A', + // ngModelOptions needs to run before ngModel and input directives + priority: 10, + require: {parentCtrl: '?^^ngModelOptions'}, + bindToController: true, + controller: NgModelOptionsController + }; +}; + + +// shallow copy over values from `src` that are not already specified on `dst` +function defaults(dst, src) { + forEach(src, function(value, key) { + if (!isDefined(dst[key])) { + dst[key] = value; + } + }); } /** @@ -20643,6 +33148,301 @@ var ngPluralizeDirective = ['$locale', '$interpolate', '$log', function($locale, }; }]; +/** + * @ngdoc directive + * @name ngRef + * @restrict A + * + * @description + * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive) + * to the given property in the current scope.
