The Animation interface of the Web Animations API represents a single animation player and provides playback controls and a timeline for an animation node or source.

Properties

currentTime: CSSNumberish | null

The Animation.currentTime property of the Web Animations API returns and sets the current time value of the animation in milliseconds, whether running or paused.

MDN Reference

effect: AnimationEffect | null

The Animation.effect property of the Web Animations API gets and sets the target effect of an animation.

MDN Reference

finished: Promise<Animation>

The Animation.finished read-only property of the Web Animations API returns a Promise which resolves once the animation has finished playing.

MDN Reference

id: string

The Animation.id property of the Web Animations API returns or sets a string used to identify the animation.

MDN Reference

oncancel: ((this: Animation, ev: AnimationPlaybackEvent) => any) | null
onfinish: ((this: Animation, ev: AnimationPlaybackEvent) => any) | null
onremove: ((this: Animation, ev: AnimationPlaybackEvent) => any) | null
pending: boolean

The read-only Animation.pending property of the Web Animations API indicates whether the animation is currently waiting for an asynchronous operation such as initiating playback or pausing a running animation.

MDN Reference

playbackRate: number

The Animation.playbackRate property of the Web Animations API returns or sets the playback rate of the animation.

MDN Reference

The read-only Animation.playState property of the Web Animations API returns an enumerated value describing the playback state of an animation.

MDN Reference

ready: Promise<Animation>

The read-only Animation.ready property of the Web Animations API returns a Promise which resolves when the animation is ready to play.

MDN Reference

replaceState: AnimationReplaceState

The read-only Animation.replaceState property of the Web Animations API indicates whether the animation has been removed by the browser automatically after being replaced by another animation.

MDN Reference

startTime: CSSNumberish | null

The Animation.startTime property of the Animation interface is a double-precision floating-point value which indicates the scheduled time when an animation's playback should begin.

MDN Reference

timeline: AnimationTimeline | null

The Animation.timeline property of the Animation interface returns or sets the AnimationTimeline associated with this animation.

Methods

  • The Web Animations API's cancel() method of the Animation interface clears all KeyframeEffects caused by this animation and aborts its playback.

    MDN Reference

    Returns void

  • The commitStyles() method of the Web Animations API's Animation interface writes the computed values of the animation's current styles into its target element's style attribute.

    MDN Reference

    Returns void

  • The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order.

    MDN Reference

    Parameters

    • event: Event

    Returns boolean

  • The finish() method of the Web Animations API's Animation Interface sets the current playback time to the end of the animation corresponding to the current playback direction.

    MDN Reference

    Returns void

  • The pause() method of the Web Animations API's Animation interface suspends playback of the animation.

    MDN Reference

    Returns void

  • The persist() method of the Web Animations API's Animation interface explicitly persists an animation, preventing it from being automatically removed when it is replaced by another animation.

    MDN Reference

    Returns void

  • The play() method of the Web Animations API's Animation Interface starts or resumes playing of an animation.

    MDN Reference

    Returns void

  • The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target.

    MDN Reference

    Type Parameters

    Parameters

    Returns void

  • The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target.

    MDN Reference

    Parameters

    Returns void

  • The Animation.reverse() method of the Animation Interface reverses the playback direction, meaning the animation ends at its beginning.

    MDN Reference

    Returns void

  • The updatePlaybackRate() method of the Web Animations API's synchronizing its playback position.

    MDN Reference

    Parameters

    • playbackRate: number

    Returns void
