|
||
* @description
|
||
*
|
||
* The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives.
|
||
*
|
||
* <div doc-module-components="ngAnimate"></div>
|
||
*
|
||
* # Usage
|
||
*
|
||
* To see animations in action, all that is required is to define the appropriate CSS classes
|
||
* or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are:
|
||
* `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
|
||
* by using the `$animate` service.
|
||
*
|
||
* Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
|
||
*
|
||
* | Directive | Supported Animations |
|
||
* |-----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
|
||
* | {@link ng.directive:ngRepeat#usage_animations ngRepeat} | enter, leave and move |
|
||
* | {@link ngRoute.directive:ngView#usage_animations ngView} | enter and leave |
|
||
* | {@link ng.directive:ngInclude#usage_animations ngInclude} | enter and leave |
|
||
* | {@link ng.directive:ngSwitch#usage_animations ngSwitch} | enter and leave |
|
||
* | {@link ng.directive:ngIf#usage_animations ngIf} | enter and leave |
|
||
* | {@link ng.directive:ngClass#usage_animations ngClass} | add and remove (the CSS class(es) present) |
|
||
* | {@link ng.directive:ngShow#usage_animations ngShow} & {@link ng.directive:ngHide#usage_animations ngHide} | add and remove (the ng-hide class value) |
|
||
* | {@link ng.directive:form#usage_animations form} & {@link ng.directive:ngModel#usage_animations ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) |
|
||
* | {@link ngMessages.directive:ngMessage#usage_animations ngMessages} | add and remove (ng-active & ng-inactive) |
|
||
* | {@link ngMessages.directive:ngMessage#usage_animations ngMessage} | enter and leave |
|
||
*
|
||
* You can find out more information about animations upon visiting each directive page.
|
||
*
|
||
* Below is an example of how to apply animations to a directive that supports animation hooks:
|
||
*
|
||
* ```html
|
||
* <style type="text/css">
|
||
* .slide.ng-enter, .slide.ng-leave {
|
||
* -webkit-transition:0.5s linear all;
|
||
* transition:0.5s linear all;
|
||
* }
|
||
*
|
||
* .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>
|
||
*
|
||
* <!--
|
||
* 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>
|
||
* ```
|
||
*
|
||
* 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.
|
||
*
|
||
* ```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>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* 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.
|
||
*
|
||
* ## 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.
|
||
*
|
||
* <h2>CSS-defined Animations</h2>
|
||
* 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;
|
||
* }
|
||
*
|
||
* /*
|
||
* 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>
|
||
*
|
||
* <div class="view-container">
|
||
* <div ng-view class="reveal-animation"></div>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* The following code below demonstrates how to perform animations using **CSS animations** with Angular:
|
||
*
|
||
* ```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>
|
||
*
|
||
* <div class="view-container">
|
||
* <div ng-view class="reveal-animation"></div>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* 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.
|
||
*
|
||
* ```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;
|
||
* }
|
||
* ```
|
||
*
|
||
* 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:
|
||
*
|
||
* ```css
|
||
* .fade {
|
||
* /* this works as expected */
|
||
* transition:1s linear all;
|
||
* opacity:0;
|
||
* }
|
||
* ```
|
||
*
|
||
* 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.
|
||
*
|
||
* ### 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, as of 1.2.0, 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;
|
||
* }
|
||
* .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;
|
||
* }
|
||
* .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 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);
|
||
* ```
|
||
*
|
||
* Stagger animations are currently only supported within CSS-defined animations.
|
||
*
|
||
* ## 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.
|
||
*
|
||
* ```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) { }
|
||
* };
|
||
* });
|
||
* ```
|
||
*
|
||
* 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).

* @ngdoc service
|

* @name $animate
|
||
* @kind object
|
||
*
|
||
* @description
|
||
* The `$animate` service provides animation detection support while performing DOM operations (enter, leave and move) as well as during addClass and removeClass operations.
|
||
* When any of these operations are run, the $animate service
|
||
* will examine any JavaScript-defined animations (which are defined by using the $animateProvider provider object)
|
||
* as well as any CSS-defined animations against the CSS classes present on the element once the DOM operation is run.
|
||
*
|
||
* The `$animate` service is used behind the scenes with pre-existing directives and animation with these directives
|
||
* will work out of the box without any extra configuration.
|
||
*
|
||
* Requires the {@link ngAnimate `ngAnimate`} module to be installed.
|
||
*
|
||
* Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application.
|
||
* ## Callback Promises
|
||
* With AngularJS 1.3, each of the animation methods, on the `$animate` service, return a promise when called. The
|
||
* promise itself is then resolved once the animation has completed itself, has been cancelled or has been
|
||
* skipped due to animations being disabled. (Note that even if the animation is cancelled it will still
|
||
* call the resolve function of the animation.)
|
||
*
|
||
* ```js
|
||
* $animate.enter(element, container).then(function() {
|
||
* //...this is called once the animation is complete...
|
||
* });
|
||
* ```
|
||
*
|
||
* Also note that, due to the nature of the callback promise, if any Angular-specific code (like changing the scope,
|
||
* location of the page, etc...) is executed within the callback promise then be sure to wrap the code using
|
||
* `$scope.$apply(...)`;
|
||
*
|
||
* ```js
|
||
* $animate.leave(element).then(function() {
|
||
* $scope.$apply(function() {
|
||
* $location.path('/new-page');
|
||
* });
|
||
* });
|
||
* ```
|
||
*
|
||
* An animation can also be cancelled by calling the `$animate.cancel(promise)` method with the provided
|
||
* promise that was returned when the animation was started.
|
||
*
|
||
* ```js
|
||
* var promise = $animate.addClass(element, 'super-long-animation').then(function() {
|
||
* //this will still be called even if cancelled
|
||
* });
|
||
*
|
||
* element.on('click', function() {
|
||
* //tooo lazy to wait for the animation to end
|
||
* $animate.cancel(promise);
|
||
* });
|
||
* ```
|
||
*
|
||
* (Keep in mind that the promise cancellation is unique to `$animate` since promises in
|
||
* general cannot be cancelled.)
