Animation: finish event

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2020.

The finish event of the Animation interface is fired when the animation finishes playing, either when the animation completes naturally, or when the Animation.finish() method is called to immediately cause the animation to finish up.

Note: The "paused" play state supersedes the "finished" play state; if the animation is both paused and finished, the "paused" state is the one that will be reported. You can force the animation into the "finished" state by setting its startTime to document.timeline.currentTime - (Animation.currentTime * Animation.playbackRate).

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

js
addEventListener("finish", (event) => { })
onfinish = (event) => { }

Event type

An AnimationPlaybackEvent. Inherits from Event.

Event AnimationPlaybackEvent

Event properties

In addition to the properties listed below, properties from the parent interface, Event, are available.

AnimationPlaybackEvent.currentTime Read only

The current time of the animation that generated the event.

AnimationPlaybackEvent.timelineTime Read only

The time value of the timeline of the animation that generated the event.

Examples

Animation.onfinish is used several times in the Alice in Web Animations API Land Growing/Shrinking Alice Game. Here is one instance where we add pointer events back to an element after its opacity animation has faded it in:

js
// Add an animation to the game's ending credits
const endingUI = document.getElementById("ending-ui");
const bringUI = endingUI.animate(keysFade, timingFade);

// Pause said animation's credits
bringUI.pause();

// This function removes pointer events on the credits.
hide(endingUI);

// When the credits are later faded in,
// we re-add the pointer events when they're done
bringUI.onfinish = (event) => {
  endingUI.style.pointerEvents = "auto";
};
