|
|
*
|
|
* @usageNotes
|
|
* Define an animation trigger in the `animations` section of `@Component` metadata.
|
|
* In the template, reference the trigger by name and bind it to a trigger expression that
|
|
* evaluates to a defined animation state, using the following format:
|
|
*
|
|
* `[@triggerName]="expression"`
|
|
*
|
|
* Animation trigger bindings convert all values to strings, and then match the
|
|
* previous and current values against any linked transitions.
|
|
* Booleans can be specified as `1` or `true` and `0` or `false`.
|
|
*
|
|
* ### Usage Example
|
|
*
|
|
* The following example creates an animation trigger reference based on the provided
|
|
* name value.
|
|
* The provided animation value is expected to be an array consisting of state and
|
|
* transition declarations.
|
|
*
|
|
* ```typescript
|
|
* @Component({
|
|
* selector: "my-component",
|
|
* templateUrl: "my-component-tpl.html",
|
|
* animations: [
|
|
* trigger("myAnimationTrigger", [
|
|
* state(...),
|
|
* state(...),
|
|
* transition(...),
|
|
* transition(...)
|
|
* ])
|
|
* ]
|
|
* })
|
|
* class MyComponent {
|
|
* myStatusExp = "something";
|
|
* }
|
|
* ```
|
|
*
|
|
* The template associated with this component makes use of the defined trigger
|
|
* by binding to an element within its template code.
|
|
*
|
|
* ```html
|
|
* <!-- somewhere inside of my-component-tpl.html -->
|
|
* <div [@myAnimationTrigger]="myStatusExp">...</div>
|
|
* ```
|
|
*
|
|
* ### Using an inline function
|
|
* The `transition` animation method also supports reading an inline function which can decide
|
|
* if its associated animation should be run.
|
|
*
|
|
* ```typescript
|
|
* // this method is run each time the `myAnimationTrigger` trigger value changes.
|
|
* function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
|
|
string]: any}): boolean {
|
|
* // notice that `element` and `params` are also available here
|
|
* return toState == 'yes-please-animate';
|
|
* }
|
|
*
|
|
* @Component({
|
|
* selector: 'my-component',
|
|
* templateUrl: 'my-component-tpl.html',
|
|
* animations: [
|
|
* trigger('myAnimationTrigger', [
|
|
* transition(myInlineMatcherFn, [
|
|
* // the animation sequence code
|
|
* ]),
|
|
* ])
|
|
* ]
|
|
* })
|
|
* class MyComponent {
|
|
* myStatusExp = "yes-please-animate";
|
|
* }
|
|
* ```
|
|
*
|
|
* ### Disabling Animations
|
|
* When true, the special animation control binding `@.disabled` binding prevents
|
|
* all animations from rendering.
|
|
* Place the `@.disabled` binding on an element to disable
|
|
* animations on the element itself, as well as any inner animation triggers
|
|
* within the element.
|
|
*
|
|
* The following example shows how to use this feature:
|
|
*
|
|
* ```typescript
|
|
* @Component({
|
|
* selector: 'my-component',
|
|
* template: `
|
|
* <div [@.disabled]="isDisabled">
|
|
* <div [@childAnimation]="exp"></div>
|
|
* </div>
|
|
* `,
|
|
* animations: [
|
|
* trigger("childAnimation", [
|
|
* // ...
|
|
* ])
|
|
* ]
|
|
* })
|
|
* class MyComponent {
|
|
* isDisabled = true;
|
|
* exp = '...';
|
|
* }
|
|
* ```
|
|
*
|
|
* When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,
|
|
* along with any inner animations.
|
|
*
|
|
* ### Disable animations application-wide
|
|
* When an area of the template is set to have animations disabled,
|
|
* **all** inner components have their animations disabled as well.
|
|
* This means that you can disable all animations for an app
|
|
* by placing a host binding set on `@.disabled` on the topmost Angular component.
|
|
*
|
|
* ```typescript
|
|
* import {Component, HostBinding} from '@angular/core';
|
|
*
|
|
* @Component({
|
|
* selector: 'app-component',
|
|
* templateUrl: 'app.component.html',
|
|
* })
|
|
* class AppComponent {
|
|
* @HostBinding('@.disabled')
|
|
* public animationsDisabled = true;
|
|
* }
|
|
* ```
|
|
*
|
|
* ### Overriding disablement of inner animations
|
|
* Despite inner animations being disabled, a parent animation can `query()`
|
|
* for inner elements located in disabled areas of the template and still animate
|
|
* them if needed. This is also the case for when a sub animation is
|
|
* queried by a parent and then later animated using `animateChild()`.
|
|
*
|
|
* ### Detecting when an animation is disabled
|
|
* If a region of the DOM (or the entire application) has its animations disabled, the animation
|
|
* trigger callbacks still fire, but for zero seconds. When the callback fires, it provides
|
|
* an instance of an `AnimationEvent`. If animations are disabled,
|
|
* the `.disabled` flag on the event is true.
|
|
*

|
|
*
|
|
* @param timings Sets `AnimateTimings` for the parent animation.
|

* A string in the format "duration [delay] [easing]".
|
|
* - Duration and delay are expressed as a number and optional time unit,

|
* such as "1s" or "10ms" for one second and 10 milliseconds, respectively.
|
|
* The default unit is milliseconds.
|
|
* - The easing value controls how the animation accelerates and decelerates
|
|
* during its runtime. Value is one of `ease`, `ease-in`, `ease-out`,
|
|
* `ease-in-out`, or a `cubic-bezier()` function call.
|
|
* If not supplied, no easing is applied.
|
|
*
|

|
|
*
|
|
* ### Syntax Examples
|
|
* **Timing examples**
|
|
*
|
|
* The following examples show various `timings` specifications.
|
|
* - `animate(500)` : Duration is 500 milliseconds.
|
|
* - `animate("1s")` : Duration is 1000 milliseconds.
|
|
* - `animate("100ms 0.5s")` : Duration is 100 milliseconds, delay is 500 milliseconds.
|
|
* - `animate("5s ease-in")` : Duration is 5000 milliseconds, easing in.
|
|
* - `animate("5s 10ms cubic-bezier(.17,.67,.88,.1)")` : Duration is 5000 milliseconds, delay is 10
|
|
* milliseconds, easing according to a bezier curve.
|
|
*
|
|
* **Style examples**
|
|
*
|
|
* The following example calls `style()` to set a single CSS style.
|
|
* ```typescript
|
|
* animate(500, style({ background: "red" }))
|
|
* ```
|
|
* The following example calls `keyframes()` to set a CSS style
|
|
* to different values for successive keyframes.
|
|
* ```typescript
|
|
* animate(500, keyframes(
|
|
* [
|
|
* style({ background: "blue" }),
|
|
* style({ background: "red" })
|
|
* ])

|

|
* blue when 20% of the total time has elapsed.
|
|
*
|

* ```typescript
|
|
* // the provided offset values
|
|
* animate("5s", keyframes([
|
|
* style({ backgroundColor: "red", offset: 0 }),
|
|
* style({ backgroundColor: "blue", offset: 0.2 }),
|
|
* style({ backgroundColor: "orange", offset: 0.3 }),
|
|
* style({ backgroundColor: "black", offset: 1 })
|
|
* ]))
|
|
* ```
|
|
*
|
|
* If there are no `offset` values specified in the style entries, the offsets
|
|
* are calculated automatically.
|
|
*
|
|
* ```typescript
|
|
* animate("5s", keyframes([
|
|
* style({ backgroundColor: "red" }) // offset = 0
|
|
* style({ backgroundColor: "blue" }) // offset = 0.33
|
|
* style({ backgroundColor: "orange" }) // offset = 0.66
|
|
* style({ backgroundColor: "black" }) // offset = 1

|
* ### State Change Expression
|
|
*
|
|
* The State Change Expression instructs Angular when to run the transition's animations, it can
|
|
*either be
|
|
* - a string with a specific syntax
|
|
* - or a function that compares the previous and current state (value of the expression bound to
|
|
* the element's trigger) and returns `true` if the transition should occur or `false` otherwise
|
|
*
|
|
* The string format can be:
|
|
* - `fromState => toState`, which indicates that the transition's animations should occur then the
|
|
* expression bound to the trigger's element goes from `fromState` to `toState`
|
|
*
|
|
* _Example:_
|
|
* ```typescript
|
|
* transition('open => closed', animate('.5s ease-out', style({ height: 0 }) ))
|
|
* ```
|
|
*
|
|
* - `fromState <=> toState`, which indicates that the transition's animations should occur then
|
|
* the expression bound to the trigger's element goes from `fromState` to `toState` or vice versa
|
|
*
|
|
* _Example:_
|
|
* ```typescript
|
|
* transition('enabled <=> disabled', animate('1s cubic-bezier(0.8,0.3,0,1)'))
|
|
* ```
|
|
*
|
|
* - `:enter`/`:leave`, which indicates that the transition's animations should occur when the
|
|
* element enters or exists the DOM
|
|
*
|
|
* _Example:_
|
|
* ```typescript
|
|
* transition(':enter', [
|
|
* style({ opacity: 0 }),
|
|
* animate('500ms', style({ opacity: 1 }))
|
|
* ])
|
|
* ```
|
|
*
|
|
* - `:increment`/`:decrement`, which indicates that the transition's animations should occur when
|
|
* the numerical expression bound to the trigger's element has increased in value or decreased
|
|
*
|
|
* _Example:_
|
|
* ```typescript
|
|
* transition(':increment', query('@counter', animateChild()))
|
|
* ```
|
|
*
|
|
* - a sequence of any of the above divided by commas, which indicates that transition's animations
|
|
* should occur whenever one of the state change expressions matches
|
|
*
|
|
* _Example:_
|
|
* ```typescript
|
|
* transition(':increment, * => enabled, :enter', animate('1s ease', keyframes([
|
|
* style({ transform: 'scale(1)', offset: 0}),
|
|
* style({ transform: 'scale(1.1)', offset: 0.7}),
|
|
* style({ transform: 'scale(1)', offset: 1})
|
|
* ]))),
|
|
* ```
|
|
*
|
|
* Also note that in such context:
|
|
* - `void` can be used to indicate the absence of the element
|
|
* - asterisks can be used as wildcards that match any state
|
|
* - (as a consequence of the above, `void => *` is equivalent to `:enter` and `* => void` is
|
|
* equivalent to `:leave`)
|
|
* - `true` and `false` also match expression values of `1` and `0` respectively (but do not match
|
|
* _truthy_ and _falsy_ values)
|
|
*
|
|
* <div class="alert is-helpful">
|
|
*
|
|
* Be careful about entering end leaving elements as their transitions present a common
|
|
* pitfall for developers.
|
|
*
|
|
* Note that when an element with a trigger enters the DOM its `:enter` transition always
|
|
* gets executed, but its `:leave` transition will not be executed if the element is removed
|
|
* alongside its parent (as it will be removed "without warning" before its transition has
|
|
* a chance to be executed, the only way that such transition can occur is if the element
|
|
* is exiting the DOM on its own).
|
|
*
|
|
*
|
|
* </div>
|
|
*
|
|
* ### Animating to a Final State
|
|
*
|
|
* If the final step in a transition is a call to `animate()` that uses a timing value
|
|
* with no `style` data, that step is automatically considered the final animation arc,
|
|
* for the element to reach the final state, in such case Angular automatically adds or removes
|
|
* CSS styles to ensure that the element is in the correct final state.
|
|
*
|
|
*
|
|
* ### Usage Examples
|
|
*
|
|
* - Transition animations applied based on
|
|
* the trigger's expression value
|
|
*
|
|
* ```HTML
|
|
* <div [@myAnimationTrigger]="myStatusExp">
|
|
* ...
|
|
* </div>
|
|
* ```
|
|
*
|
|
* ```typescript
|
|
* trigger("myAnimationTrigger", [
|
|
* ..., // states
|
|
* transition("on => off, open => closed", animate(500)),
|
|
* transition("* <=> error", query('.indicator', animateChild()))
|
|
* ])
|
|
* ```
|
|
*
|
|
* - Transition animations applied based on custom logic dependent
|
|
* on the trigger's expression value and provided parameters
|
|
*
|
|
* ```HTML
|
|
* <div [@myAnimationTrigger]="{
|
|
* value: stepName,
|
|
* params: { target: currentTarget }
|
|
* }">
|
|
* ...
|
|
* </div>
|
|
* ```
|
|
*
|
|
* ```typescript
|
|
* trigger("myAnimationTrigger", [
|
|
* ..., // states
|
|
* transition(
|
|
* (fromState, toState, _element, params) =>
|
|
* ['firststep', 'laststep'].includes(fromState.toLowerCase())
|
|
* && toState === params?.['target'],
|
|
* animate('1s')
|
|
* )
|

|
|
*
|
|
* @usageNotes
|
|
*
|
|
* ### Multiple Tokens
|
|
*
|
|
* Tokens can be merged into a combined query selector string. For example:
|
|
*
|
|
* ```typescript
|
|
* query(':self, .record:enter, .record:leave, @subTrigger', [...])
|
|
* ```
|
|
*
|
|
* The `query()` function collects multiple elements and works internally by using
|
|
* `element.querySelectorAll`. Use the `limit` field of an options object to limit
|
|
* the total number of items to be collected. For example:
|
|
*
|
|
* ```js
|
|
* query('div', [
|
|
* animate(...),
|
|
* animate(...)
|
|
* ], { limit: 1 })
|
|
* ```
|
|
*
|
|
* By default, throws an error when zero items are found. Set the
|
|
* `optional` flag to ignore this error. For example:
|
|
*
|
|
* ```js
|
|
* query('.some-element-that-may-not-be-there', [
|
|
* animate(...),
|
|
* animate(...)
|
|
* ], { optional: true })
|
|
* ```
|
|
*
|
|
* ### Entering and Leaving Elements
|
|
*
|
|
* Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones
|
|
* that can are those that Angular assumes can enter/leave based on their own logic
|
|
* (if their insertion/removal is simply a consequence of that of their parent they
|
|
* should be queried via a different token in their parent's `:enter`/`:leave` transitions).
|
|
*
|
|
* The only elements Angular assumes can enter/leave based on their own logic (thus the only
|
|
* ones that can be queried via the `:enter` and `:leave` tokens) are:
|
|
* - Those inserted dynamically (via `ViewContainerRef`)
|
|
* - Those that have a structural directive (which, under the hood, are a subset of the above ones)
|
|
*
|
|
* <div class="alert is-helpful">
|
|
*
|
|
* Note that elements will be successfully queried via `:enter`/`:leave` even if their
|
|
* insertion/removal is not done manually via `ViewContainerRef`or caused by their structural
|
|
* directive (e.g. they enter/exit alongside their parent).
|
|
*
|
|
* </div>
|
|
*
|
|
* <div class="alert is-important">
|
|
*
|
|
* There is an exception to what previously mentioned, besides elements entering/leaving based on
|
|
* their own logic, elements with an animation trigger can always be queried via `:leave` when
|
|
* their parent is also leaving.
|
|
*
|
|
* </div>
|
|
*
|
|
* ### Usage Example
|
|
*
|
|
* The following example queries for inner elements and animates them
|
|
* individually using `animate()`.
|
|
*
|
|
* ```typescript
|
|
* @Component({
|
|
* selector: 'inner',
|
|
* template: `
|
|
* <div [@queryAnimation]="exp">
|
|
* <h1>Title</h1>
|
|
* <div class="content">
|
|
* Blah blah blah
|
|
* </div>
|
|
* </div>
|
|
* `,
|
|
* animations: [
|
|
* trigger('queryAnimation', [
|
|
* transition('* => goAnimate', [
|
|
* // hide the inner elements
|
|
* query('h1', style({ opacity: 0 })),
|
|
* query('.content', style({ opacity: 0 })),
|
|
*
|
|
* // animate the inner elements in, one by one
|
|
* query('h1', animate(1000, style({ opacity: 1 }))),
|
|
* query('.content', animate(1000, style({ opacity: 1 }))),
|
|
* ])
|
|
* ])
|
|
* ]
|
|
* })
|
|
* class Cmp {
|
|
* exp = '';
|
|
*
|
|
* goAnimate() {
|
|
* this.exp = 'goAnimate';
|
|
* }
|
|
* }

* ```
