The purpose of `$animateCss` is NOT + * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or + * directives to create more complex animations that can be purely driven using CSS code. * - * .slide.ng-enter { } /* starting animations for enter */ - * .slide.ng-enter.ng-enter-active { } /* terminal animations for enter */ - * .slide.ng-leave { } /* starting animations for leave */ - * .slide.ng-leave.ng-leave-active { } /* terminal animations for leave */ - * </style> + * Note that only browsers that support CSS transitions and/or keyframe animations are capable of + * rendering animations triggered via `$animateCss` (bad news for IE9 and lower). * - * <!-- - * the animate service will automatically add .ng-enter and .ng-leave to the element - * to trigger the CSS transition/animations - * --> - * <ANY class="slide" ng-include="..."></ANY> - * ``` + * ## Usage + * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that + * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however, + * any automatic control over cancelling animations and/or preventing animations from being run on + * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to + * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger + * the CSS animation. * - * Keep in mind that, by default, if an animation is running, any child elements cannot be animated - * until the parent element's animation has completed. This blocking feature can be overridden by - * placing the `ng-animate-children` attribute on a parent container tag. + * The example below shows how we can create a folding animation on an element using `ng-if`: * * ```html - * <div class="slide-animation" ng-if="on" ng-animate-children> - * <div class="fade-animation" ng-if="on"> - * <div class="explode-animation" ng-if="on"> - * ... - * </div> - * </div> + * <!-- notice the `fold-animation` CSS class --> + * <div ng-if="onOff" class="fold-animation"> + * This element will go BOOM * </div> + * <button ng-click="onOff=true">Fold In</button> * ``` * - * When the `on` expression value changes and an animation is triggered then each of the elements within - * will all animate without the block being applied to child elements. + * Now we create the **JavaScript animation** that will trigger the CSS transition: * - * ## Are animations run when the application starts? - * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid - * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work, - * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering - * layout changes in the application will trigger animations as normal. - * - * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular - * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests - * are complete. - * - * ## CSS-defined Animations - * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes - * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported - * and can be used to play along with this naming structure. - * - * The following code below demonstrates how to perform animations using **CSS transitions** with Angular: - * - * ```html - * <style type="text/css"> - * /* - * The animate class is apart of the element and the ng-enter class - * is attached to the element once the enter animation event is triggered - * */ - * .reveal-animation.ng-enter { - * -webkit-transition: 1s linear all; /* Safari/Chrome */ - * transition: 1s linear all; /* All other modern browsers and IE10+ */ - * - * /* The animation preparation code */ - * opacity: 0; - * } + * ```js + * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { + * return { + * enter: function(element, doneFn) { + * var height = element[0].offsetHeight; + * return $animateCss(element, { + * from: { height:'0px' }, + * to: { height:height + 'px' }, + * duration: 1 // one second + * }); + * } + * } + * }]); + * ``` * - * /* - * Keep in mind that you want to combine both CSS - * classes together to avoid any CSS-specificity - * conflicts - * */ - * .reveal-animation.ng-enter.ng-enter-active { - * /* The animation code itself */ - * opacity: 1; - * } - * </style> + * ## More Advanced Uses * - * <div class="view-container"> - * <div ng-view class="reveal-animation"></div> - * </div> - * ``` + * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks + * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code. * - * The following code below demonstrates how to perform animations using **CSS animations** with Angular: + * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation, + * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with + * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order + * to provide a working animation that will run in CSS. * - * ```html - * <style type="text/css"> - * .reveal-animation.ng-enter { - * -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */ - * animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */ - * } - * @-webkit-keyframes enter_sequence { - * from { opacity:0; } - * to { opacity:1; } - * } - * @keyframes enter_sequence { - * from { opacity:0; } - * to { opacity:1; } - * } - * </style> + * The example below showcases a more advanced version of the `.fold-animation` from the example above: * - * <div class="view-container"> - * <div ng-view class="reveal-animation"></div> - * </div> + * ```js + * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { + * return { + * enter: function(element, doneFn) { + * var height = element[0].offsetHeight; + * return $animateCss(element, { + * addClass: 'red large-text pulse-twice', + * easing: 'ease-out', + * from: { height:'0px' }, + * to: { height:height + 'px' }, + * duration: 1 // one second + * }); + * } + * } + * }]); * ``` * - * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing. - * - * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add - * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically - * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be - * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end - * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element - * has no CSS transition/animation classes applied to it. - * - * ### Structural transition animations - * - * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition - * value to force the browser into rendering the styles defined in the setup (`.ng-enter`, `.ng-leave` - * or `.ng-move`) class. This means that any active transition animations operating on the element - * will be cut off to make way for the enter, leave or move animation. - * - * ### Class-based transition animations - * - * Class-based transitions refer to transition animations that are triggered when a CSS class is - * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`, - * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`). - * They are different when compared to structural animations since they **do not cancel existing - * animations** nor do they **block successive transitions** from rendering on the same element. - * This distinction allows for **multiple class-based transitions** to be performed on the same element. - * - * In addition to ngAnimate supporting the default (natural) functionality of class-based transition - * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the - * developer in further styling the element throughout the transition animation. Earlier versions - * of ngAnimate may have caused natural CSS transitions to break and not render properly due to - * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class - * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of - * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS - * class transitions are compatible with ngAnimate. - * - * There is, however, one special case when dealing with class-based transitions in ngAnimate. - * When rendering class-based transitions that make use of the setup and active CSS classes - * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define - * the transition value **on the active CSS class** and not the setup class. + * Since we're adding/removing CSS classes then the CSS transition will also pick those up: * * ```css - * .fade-add { - * /* remember to place a 0s transition here - * to ensure that the styles are applied instantly - * even if the element already has a transition style */ - * transition:0s linear all; - * - * /* starting CSS styles */ - * opacity:1; - * } - * .fade-add.fade-add-active { - * /* this will be the length of the animation */ - * transition:1s linear all; - * opacity:0; + * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code, + * the CSS classes below will be transitioned despite them being defined as regular CSS classes */ + * .red { background:red; } + * .large-text { font-size:20px; } + * + * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */ + * .pulse-twice { + * animation: 0.5s pulse linear 2; + * -webkit-animation: 0.5s pulse linear 2; * } - * ``` - * - * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it - * has a duration of zero. This may not be required, however, incase the browser is unable to render - * the styling present in this CSS class instantly then it could be that the browser is attempting - * to perform an unnecessary transition. * - * This workaround, however, does not apply to standard class-based transitions that are rendered - * when a CSS class containing a transition is applied to an element: + * @keyframes pulse { + * from { transform: scale(0.5); } + * to { transform: scale(1.5); } + * } * - * ```css - * /* this works as expected */ - * .fade { - * transition:1s linear all; - * opacity:0; + * @-webkit-keyframes pulse { + * from { -webkit-transform: scale(0.5); } + * to { -webkit-transform: scale(1.5); } * } * ``` * - * Please keep this in mind when coding the CSS markup that will be used within class-based transitions. - * Also, try not to mix the two class-based animation flavors together since the CSS code may become - * overly complex. - * - * - * ### Preventing Collisions With Third Party Libraries - * - * Some third-party frameworks place animation duration defaults across many element or className - * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which - * is expecting actual animations on these elements and has to wait for their completion. + * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen. * - * You can prevent this unwanted behavior by using a prefix on all your animation classes: - * - * ```css - * /* prefixed with animate- */ - * .animate-fade-add.animate-fade-add-active { - * transition:1s linear all; - * opacity:0; - * } - * ``` + * ## How the Options are handled * - * You then configure `$animate` to enforce this prefix: + * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation + * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline + * styles using the `from` and `to` properties. * * ```js - * $animateProvider.classNameFilter(/animate-/); + * var animator = $animateCss(element, { + * from: { background:'red' }, + * to: { background:'blue' } + * }); + * animator.start(); * ``` - * </div> - * - * ### CSS Staggering Animations - * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a - * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be - * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for - * the animation. The style property expected within the stagger class can either be a **transition-delay** or an - * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). * * ```css - * .my-animation.ng-enter { - * /* standard transition code */ - * -webkit-transition: 1s linear all; - * transition: 1s linear all; - * opacity:0; + * .rotating-animation { + * animation:0.5s rotate linear; + * -webkit-animation:0.5s rotate linear; * } - * .my-animation.ng-enter-stagger { - * /* this will have a 100ms delay between each successive leave animation */ - * -webkit-transition-delay: 0.1s; - * transition-delay: 0.1s; * - * /* in case the stagger doesn't work then these two values - * must be set to 0 to avoid an accidental CSS inheritance */ - * -webkit-transition-duration: 0s; - * transition-duration: 0s; + * @keyframes rotate { + * from { transform: rotate(0deg); } + * to { transform: rotate(360deg); } * } - * .my-animation.ng-enter.ng-enter-active { - * /* standard transition styles */ - * opacity:1; + * + * @-webkit-keyframes rotate { + * from { -webkit-transform: rotate(0deg); } + * to { -webkit-transform: rotate(360deg); } * } * ``` * - * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations - * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this - * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation - * will also be reset if more than 10ms has passed after the last animation has been fired. - * - * The following code will issue the **ng-leave-stagger** event on the element provided: - * - * ```js - * var kids = parent.children(); - * - * $animate.leave(kids[0]); //stagger index=0 - * $animate.leave(kids[1]); //stagger index=1 - * $animate.leave(kids[2]); //stagger index=2 - * $animate.leave(kids[3]); //stagger index=3 - * $animate.leave(kids[4]); //stagger index=4 - * - * $timeout(function() { - * //stagger has reset itself - * $animate.leave(kids[5]); //stagger index=0 - * $animate.leave(kids[6]); //stagger index=1 - * }, 100, false); - * ``` + * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is + * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition + * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition + * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied + * and spread across the transition and keyframe animation. * - * Stagger animations are currently only supported within CSS-defined animations. + * ## What is returned * - * ## JavaScript-defined Animations - * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not - * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module. + * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually + * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are + * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties: * * ```js - * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application. - * var ngModule = angular.module('YourApp', ['ngAnimate']); - * ngModule.animation('.my-crazy-animation', function() { - * return { - * enter: function(element, done) { - * //run the animation here and call done when the animation is complete - * return function(cancelled) { - * //this (optional) function will be called when the animation - * //completes or when the animation is cancelled (the cancelled - * //flag will be set to true if cancelled). - * }; - * }, - * leave: function(element, done) { }, - * move: function(element, done) { }, - * - * //animation that can be triggered before the class is added - * beforeAddClass: function(element, className, done) { }, - * - * //animation that can be triggered after the class is added - * addClass: function(element, className, done) { }, - * - * //animation that can be triggered before the class is removed - * beforeRemoveClass: function(element, className, done) { }, - * - * //animation that can be triggered after the class is removed - * removeClass: function(element, className, done) { } - * }; - * }); + * var animator = $animateCss(element, { ... }); * ``` * - * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run - * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits - * the element's CSS class attribute value and then run the matching animation event function (if found). - * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will - * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported). - * - * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned. - * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run, - * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation - * or transition code that is defined via a stylesheet). - * - * - * ### Applying Directive-specific Styles to an Animation - * In some cases a directive or service may want to provide `$animate` with extra details that the animation will - * include into its animation. Let's say for example we wanted to render an animation that animates an element - * towards the mouse coordinates as to where the user clicked last. By collecting the X/Y coordinates of the click - * (via the event parameter) we can set the `top` and `left` styles into an object and pass that into our function - * call to `$animate.addClass`. + * Now what do the contents of our `animator` variable look like: * * ```js - * canvas.on('click', function(e) { - * $animate.addClass(element, 'on', { - * to: { - * left : e.client.x + 'px', - * top : e.client.y + 'px' - * } - * }): - * }); - * ``` + * { + * // starts the animation + * start: Function, * - * Now when the animation runs, and a transition or keyframe animation is picked up, then the animation itself will - * also include and transition the styling of the `left` and `top` properties into its running animation. If we want - * to provide some starting animation values then we can do so by placing the starting animations styles into an object - * called `from` in the same object as the `to` animations. - * - * ```js - * canvas.on('click', function(e) { - * $animate.addClass(element, 'on', { - * from: { - * position: 'absolute', - * left: '0px', - * top: '0px' - * }, - * to: { - * left : e.client.x + 'px', - * top : e.client.y + 'px' - * } - * }): - * }); + * // ends (aborts) the animation + * end: Function + * } * ``` * - * Once the animation is complete or cancelled then the union of both the before and after styles are applied to the - * element. If `ngAnimate` is not present then the styles will be applied immediately. - * + * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends. + * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and stlyes may have been + * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties + * and that changing them will not reconfigure the parameters of the animation. + * + * ### runner.done() vs runner.then() + * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the + * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**. + * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()` + * unless you really need a digest to kick off afterwards. + * + * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss + * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code). + * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works. + * + * @param {DOMElement} element the element that will be animated + * @param {object} options the animation-related options that will be applied during the animation + * + * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied + * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.) + * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and + * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted. + * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both). + * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`). + * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`). + * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation. + * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition. + * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation. + * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation. + * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0` + * is provided then the animation will be skipped entirely. + * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is + * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value + * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same + * CSS delay value. + * * `stagger` - A numeric time value representing the delay between successively animated elements + * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.}) + * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a + * * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`) + * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occuring on the classes being added and removed.) + * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once + * the animation is closed. This is useful for when the styles are used purely for the sake of + * the animation and do not have a lasting visual effect on the element (e.g. a colapse and open animation). + * By default this value is set to `false`. + * + * @return {object} an object with start and end methods and details about the animation. + * + * * `start` - The method to start the animation. This will return a `Promise` when called. + * * `end` - This method will cancel the animation and remove all applied CSS classes and styles. */ +var ONE_SECOND = 1000; +var BASE_TEN = 10; + +var ELAPSED_TIME_MAX_DECIMAL_PLACES = 3; +var CLOSING_TIME_BUFFER = 1.5; + +var DETECT_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + transitionProperty: TRANSITION_PROP + PROPERTY_KEY, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP, + animationIterationCount: ANIMATION_PROP + ANIMATION_ITERATION_COUNT_KEY +}; + +var DETECT_STAGGER_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP +}; + +function getCssKeyframeDurationStyle(duration) { + return [ANIMATION_DURATION_PROP, duration + 's']; +} + +function getCssDelayStyle(delay, isKeyframeAnimation) { + var prop = isKeyframeAnimation ?

Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app. + * + * <div doc-module-components="ngAnimate"></div> + * + * # Usage + * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based + * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For + * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within + * the HTML element that the animation will be triggered on. + * + * ## Directive Support + * The following directives are "animation aware": + * + * | Directive | Supported Animations | + * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------| + * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move | + * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave | + * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave | + * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave | + * | {@link ng.directive:ngIf#animations ngIf} | enter and leave | + * | {@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) | + * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) | + * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) | + * | {@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) | + * | {@link module:ngMessages#animations ngMessage} | enter and leave | + * + * (More information can be found by visiting each the documentation associated with each directive.) + * + * ## CSS-based Animations + * + * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML + * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation. + * + * The example below shows how an `enter` animation can be made possible on an element using `ng-if`: + * + * ```html + * <div ng-if="bool" class="fade"> + * Fade me in out + * </div> + * <button ng-click="bool=true">Fade In!</button> + * <button ng-click="bool=false">Fade Out!</button> + * ``` + * + * Notice the CSS class **fade**? We can now create the CSS transition code that references this class: + * + * ```css + * /* The starting CSS styles for the enter animation */ + * .fade.ng-enter { + * transition:0.5s linear all; + * opacity:0; + * } + * + * /* The finishing CSS styles for the enter animation */ + * .fade.ng-enter.ng-enter-active { + * opacity:1; + * } + * ``` + * + * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two + * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition + * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards. + * + * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions: + * + * ```css + * /* now the element will fade out before it is removed from the DOM */ + * .fade.ng-leave { + * transition:0.5s linear all; + * opacity:1; + * } + * .fade.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class: + * + * ```css + * /* there is no need to define anything inside of the destination + * CSS class since the keyframe will take charge of the animation */ + * .fade.ng-leave { + * animation: my_fade_animation 0.5s linear; + * -webkit-animation: my_fade_animation 0.5s linear; + * } + * + * @keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * + * @-webkit-keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * ``` + * + * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element. + * + * ### CSS Class-based Animations + * + * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different + * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added + * and removed. + * + * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class: + * + * ```html + * <div ng-show="bool" class="fade"> + * Show and hide me + * </div> + * <button ng-click="bool=true">Toggle</button> + * + * <style> + * .fade.ng-hide { + * transition:0.5s linear all; + * opacity:0; + * } + * </style> + * ``` + * + * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since + * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest. + * + * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation + * with CSS styles. + * + * ```html + * <div ng-class="{on:onOff}" class="highlight"> + * Highlight this box + * </div> + * <button ng-click="onOff=!onOff">Toggle</button> + * + * <style> + * .highlight { + * transition:0.5s linear all; + * } + * .highlight.on-add { + * background:white; + * } + * .highlight.on { + * background:yellow; + * } + * .highlight.on-remove { + * background:black; + * } + * </style> + * ``` + * + * We can also make use of CSS keyframes by placing them within the CSS classes. + * + * + * ### CSS Staggering Animations + * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a + * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be + * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for + * the animation. The style property expected within the stagger class can either be a **transition-delay** or an + * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). + * + * ```css + * .my-animation.ng-enter { + * /* standard transition code */ + * transition: 1s linear all; + * opacity:0; + * } + * .my-animation.ng-enter-stagger { + * /* this will have a 100ms delay between each successive leave animation */ + * transition-delay: 0.1s; + * + * /* As of 1.4.4, this must always be set: it signals ngAnimate + * to not accidentally inherit a delay property from another CSS class */ + * transition-duration: 0s; + * } + * .my-animation.ng-enter.ng-enter-active { + * /* standard transition styles */ + * opacity:1; + * } + * ``` + * + * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations + * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this + * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation + * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired. + * + * The following code will issue the **ng-leave-stagger** event on the element provided: + * + * ```js + * var kids = parent.children(); + * + * $animate.leave(kids[0]); //stagger index=0 + * $animate.leave(kids[1]); //stagger index=1 + * $animate.leave(kids[2]); //stagger index=2 + * $animate.leave(kids[3]); //stagger index=3 + * $animate.leave(kids[4]); //stagger index=4 + * + * window.requestAnimationFrame(function() { + * //stagger has reset itself + * $animate.leave(kids[5]); //stagger index=0 + * $animate.leave(kids[6]); //stagger index=1 + * + * $scope.$digest(); + * }); + * ``` + * + * Stagger animations are currently only supported within CSS-defined animations. + * + * ### The `ng-animate` CSS class + * + * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation. + * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations). + * + * Therefore, animations can be applied to an element using this temporary class directly via CSS. + * + * ```css + * .zipper.ng-animate { + * transition:0.5s linear all; + * } + * .zipper.ng-enter { + * opacity:0; + * } + * .zipper.ng-enter.ng-enter-active { + * opacity:1; + * } + * .zipper.ng-leave { + * opacity:1; + * } + * .zipper.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove + * the CSS class once an animation has completed.) + * + * + * ### The `ng-[event]-prepare` class + * + * This is a special class that can be used to prevent unwanted flickering / flash of content before + * the actual animation starts. The class is added as soon as an animation is initialized, but removed + * before the actual animation starts (after waiting for a $digest). + * It is also only added for *structural* animations (`enter`, `move`, and `leave`). + * + * In practice, flickering can appear when nesting elements with structural animations such as `ngIf` + * into elements that have class-based animations such as `ngClass`. + * + * ```html + * <div ng-class="{red: myProp}"> + * <div ng-class="{blue: myProp}"> + * <div class="message" ng-if="myProp"></div> + * </div> + * </div> + * ``` + * + * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating. + * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts: + * + * ```css + * .message.ng-enter-prepare { + * opacity: 0; + * } + * + * ``` + * + * ## JavaScript-based Animations + * + * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared + * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the + * `module.animation()` module function we can register the ainmation. + * + * Let's see an example of a enter/leave animation using `ngRepeat`: + * + * ```html + * <div ng-repeat="item in items" class="slide"> + * {{ item }} + * </div> + * ``` + * + * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`: + * + * ```js + * myModule.animation('.slide', [function() { + * return { + * // make note that other events (like addClass/removeClass) + * // have different function input parameters + * enter: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); + * + * // remember to call doneFn so that angular + * // knows that the animation has concluded + * }, + * + * move: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); + * }, + * + * leave: function(element, doneFn) { + * jQuery(element).fadeOut(1000, doneFn); + * } + * } + * }]); + * ``` + * + * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as + * greensock.js and velocity.js. + * + * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define + * our animations inside of the same registered animation, however, the function input arguments are a bit different: + * + * ```html + * <div ng-class="color" class="colorful"> + * this box is moody + * </div> + * <button ng-click="color='red'">Change to red</button> + * <button ng-click="color='blue'">Change to blue</button> + * <button ng-click="color='green'">Change to green</button> + * ``` + * + * ```js + * myModule.animation('.colorful', [function() { + * return { + * addClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * removeClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * setClass: function(element, addedClass, removedClass, doneFn) { + * // do some cool animation and call the doneFn + * } + * } + * }]); + * ``` + * + * ## CSS + JS Animations Together + * + * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular, + * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking + * charge of the animation**: + * + * ```html + * <div ng-if="bool" class="slide"> + * Slide in and out + * </div> + * ``` + * + * ```js + * myModule.animation('.slide', [function() { + * return { + * enter: function(element, doneFn) { + * jQuery(element).slideIn(1000, doneFn); + * } + * } + * }]); + * ``` + * + * ```css + * .slide.ng-enter { + * transition:0.5s linear all; + * transform:translateY(-100px); + * } + * .slide.ng-enter.ng-enter-active { + * transform:translateY(0); + * } + * ``` + * + * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the + * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from + * our own JS-based animation code: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { +* // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`. + * return $animateCss(element, { + * event: 'enter', + * structural: true + * }); + * } + * } + * }]); + * ``` + * + * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework. + * + * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or + * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that + * data into `$animateCss` directly: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { + * return $animateCss(element, { + * event: 'enter', + * structural: true, + * addClass: 'maroon-setting', + * from: { height:0 }, + * to: { height: 200 } + * }); + * } + * } + * }]); + * ``` + * + * Now we can fill in the rest via our transition CSS code: + * + * ```css + * /* the transition tells ngAnimate to make the animation happen */ + * .slide.ng-enter { transition:0.5s linear all; } + * + * /* this extra CSS class will be absorbed into the transition + * since the $animateCss code is adding the class */ + * .maroon-setting { background:red; } + * ``` + * + * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over. + * + * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}. + * + * ## Animation Anchoring (via `ng-animate-ref`) + * + * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between + * structural areas of an application (like views) by pairing up elements using an attribute + * called `ng-animate-ref`. + * + * Let's say for example we have two views that are managed by `ng-view` and we want to show + * that there is a relationship between two components situated in within these views. By using the + * `ng-animate-ref` attribute we can identify that the two components are paired together and we + * can then attach an animation, which is triggered when the view changes. + * + * Say for example we have the following template code: + * + * ```html + * <!-- index.html --> + * <div ng-view class="view-animation"> + * </div> + * + * <!-- home.html --> + * <a href="#/banner-page"> + * <img src="./banner.jpg" class="banner" ng-animate-ref="banner"> + * </a> + * + * <!-- banner-page.html --> + * <img src="./banner.jpg" class="banner" ng-animate-ref="banner"> + * ``` + * + * Now, when the view changes (once the link is clicked), ngAnimate will examine the + * HTML contents to see if there is a match reference between any components in the view + * that is leaving and the view that is entering. It will scan both the view which is being + * removed (leave) and inserted (enter) to see if there are any paired DOM elements that + * contain a matching ref value. + * + * The two images match since they share the same ref value. ngAnimate will now create a + * transport element (which is a clone of the first image element) and it will then attempt + * to animate to the position of the second image element in the next view. For the animation to + * work a special CSS class called `ng-anchor` will be added to the transported element. + * + * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then + * ngAnimate will handle the entire transition for us as well as the addition and removal of + * any changes of CSS classes between the elements: + * + * ```css + * .banner.ng-anchor { + * /* this animation will last for 1 second since there are + * two phases to the animation (an `in` and an `out` phase) */ + * transition:0.5s linear all; + * } + * ``` + * + * We also **must** include animations for the views that are being entered and removed + * (otherwise anchoring wouldn't be possible since the new view would be inserted right away). + * + * ```css + * .view-animation.ng-enter, .view-animation.ng-leave { + * transition:0.5s linear all; + * position:fixed; + * left:0; + * top:0; + * width:100%; + * } + * .view-animation.ng-enter { + * transform:translateX(100%); + * } + * .view-animation.ng-leave, + * .view-animation.ng-enter.ng-enter-active { + * transform:translateX(0%); + * } + * .view-animation.ng-leave.ng-leave-active { + * transform:translateX(-100%); + * } + * ``` + * + * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur: + * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away + * from its origin. Once that animation is over then the `in` stage occurs which animates the + * element to its destination. The reason why there are two animations is to give enough time + * for the enter animation on the new element to be ready. + * + * The example above sets up a transition for both the in and out phases, but we can also target the out or + * in phases directly via `ng-anchor-out` and `ng-anchor-in`. + * + * ```css + * .banner.ng-anchor-out { + * transition: 0.5s linear all; + * + * /* the scale will be applied during the out animation, + * but will be animated away when the in animation runs */ + * transform: scale(1.2); + * } + * + * .banner.ng-anchor-in { + * transition: 1s linear all; + * } + * ``` + * + * + * + * + * ### Anchoring Demo + * + <example module="anchoringExample" + name="anchoringExample" + id="anchoringExample" + deps="angular-animate.js;angular-route.js" + animations="true"> + <file name="index.html"> + <a href="#/">Home</a> + <hr /> + <div class="view-container"> + <div ng-view class="view"></div> + </div> + </file> + <file name="script.js"> + angular.module('anchoringExample', ['ngAnimate', 'ngRoute']) + .config(['$routeProvider', function($routeProvider) { + $routeProvider.when('/', { + templateUrl: 'home.html', + controller: 'HomeController as home' + }); + $routeProvider.when('/profile/:id', { + templateUrl: 'profile.html', + controller: 'ProfileController as profile' + }); + }]) + .run(['$rootScope', function($rootScope) { + $rootScope.records = [ + { id:1, title: "Miss Beulah Roob" }, + { id:2, title: "Trent Morissette" }, + { id:3, title: "Miss Ava Pouros" }, + { id:4, title: "Rod Pouros" }, + { id:5, title: "Abdul Rice" }, + { id:6, title: "Laurie Rutherford Sr." }, + { id:7, title: "Nakia McLaughlin" }, + { id:8, title: "Jordon Blanda DVM" }, + { id:9, title: "Rhoda Hand" }, + { id:10, title: "Alexandrea Sauer" } + ]; + }]) + .controller('HomeController', [function() { + //empty + }]) + .controller('ProfileController', ['$rootScope', '$routeParams', function($rootScope, $routeParams) { + var index = parseInt($routeParams.id, 10); + var record = $rootScope.records[index - 1]; + + this.title = record.title; + this.id = record.id; + }]); + </file> + <file name="home.html"> + <h2>Welcome to the home page</h1> + <p>Please click on an element</p> + <a class="record" + ng-href="#/profile/{{ record.id }}" + ng-animate-ref="{{ record.id }}" + ng-repeat="record in records"> + {{ record.title }} + </a> + </file> + <file name="profile.html"> + <div class="profile record" ng-animate-ref="{{ profile.id }}"> + {{ profile.title }} + </div> + </file> + <file name="animations.css"> + .record { + display:block; + font-size:20px; + } + .profile { + background:black; + color:white; + font-size:100px; } - }]); - }]); + .view-container { + position:relative; + } + .view-container > .view.ng-animate { + position:absolute; + top:0; + left:0; + width:100%; + min-height:500px; + } + .view.ng-enter, .view.ng-leave, + .record.ng-anchor { + transition:0.5s linear all; + } + .view.ng-enter { + transform:translateX(100%); + } + .view.ng-enter.ng-enter-active, .view.ng-leave { + transform:translateX(0%); + } + .view.ng-leave.ng-leave-active { + transform:translateX(-100%); + } + .record.ng-anchor-out { + background:red; + } + </file> + </example> + * + * ### How is the element transported? + * + * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting + * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element + * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The + * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match + * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied + * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class + * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element + * will become visible since the shim class will be removed. + * + * ### How is the morphing handled? + * + * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out + * what CSS classes differ between the starting element and the destination element. These different CSS classes + * will be added/removed on the anchor element and a transition will be applied (the transition that is provided + * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will + * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that + * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since + * the cloned element is placed inside of root element which is likely close to the body element). + * + * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body. + * + * + * ## Using $animate in your directive code + * + * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application? + * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's + * imagine we have a greeting box that shows and hides itself when the data changes + * + * ```html + * <greeting-box active="onOrOff">Hi there</greeting-box> + * ``` + * + * ```js + * ngModule.directive('greetingBox', ['$animate', function($animate) { + * return function(scope, element, attrs) { + * attrs.$observe('active', function(value) { + * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on'); + * }); + * }); + * }]); + * ``` + * + * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element + * in our HTML code then we can trigger a CSS or JS animation to happen. + * + * ```css + * /* normally we would create a CSS class to reference on the element */ + * greeting-box.on { transition:0.5s linear all; background:green; color:white; } + * ``` + * + * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's + * possible be sure to visit the {@link ng.$animate $animate service API page}. + * + * + * ### Preventing Collisions With Third Party Libraries + * + * Some third-party frameworks place animation duration defaults across many element or className + * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which + * is expecting actual animations on these elements and has to wait for their completion. + * + * You can prevent this unwanted behavior by using a prefix on all your animation classes: + * + * ```css + * /* prefixed with animate- */ + * .animate-fade-add.animate-fade-add-active { + * transition:1s linear all; + * opacity:0; + * } + * ``` + * + * You then configure `$animate` to enforce this prefix: + * + * ```js + * $animateProvider.classNameFilter(/animate-/); + * ``` + * + * This also may provide your application with a speed boost since only specific elements containing CSS class prefix + * will be evaluated for animation when any DOM changes occur in the application. + * + * ## Callbacks and Promises + * + * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger + * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has + * ended by chaining onto the returned promise that animation method returns. + * + * ```js + * // somewhere within the depths of the directive + * $animate.enter(element, parent).then(function() { + * //the animation has completed + * }); + * ``` + * + * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case + * anymore.) + * + * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering + * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view + * routing controller to hook into that: + * + * ```js + * ngModule.controller('HomePageController', ['$animate', function($animate) { + * $animate.on('enter', ngViewElement, function(element) { + * // the animation for this route has completed + * }]); + * }]) + * ``` + * + * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.) + */ + +/** + * @ngdoc service + * @name $animate + * @kind object + * + * @description + * The ngAnimate `$animate` service documentation is the same for the core `$animate` service. + * + * Click here {@link ng.$animate to learn more about animations with `$animate`}. + */ +angular.module('ngAnimate', []) + .directive('ngAnimateChildren', $$AnimateChildrenDirective) + .factory('$$rAFScheduler', $$rAFSchedulerFactory) + + .provider('$$animateQueue', $$AnimateQueueProvider) + .provider('$$animation', $$AnimationProvider) + + .provider('$animateCss', $AnimateCssProvider) + .provider('$$animateCssDriver', $$AnimateCssDriverProvider) + + .provider('$$animateJs', $$AnimateJsProvider) + .provider('$$animateJsDriver', $$AnimateJsDriverProvider); })(window, window.angular); |
