Animation: Animation() constructor

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 Animation() constructor of the Web Animations API returns a new Animation object instance.

Syntax

js
new Animation()
new Animation(effect)
new Animation(effect, timeline)

Parameters

effect Optional

The target effect, as an object based on the AnimationEffect interface, to assign to the animation. Although in the future other effects such as SequenceEffects or GroupEffects might be possible, the only kind of effect currently available is KeyframeEffect. This can be null (which is the default) to indicate that there should be no effect applied.

timeline Optional

Specifies the timeline with which to associate the animation, as an object of a type based on the AnimationTimeline interface. The default value is Document.timeline, but this can be set to null as well.

Examples

In the Follow the White Rabbit example, we can use the Animation() constructor to create an Animation for the rabbitDownKeyframes using the document's timeline:

js
const whiteRabbit = document.getElementById("rabbit");

const rabbitDownKeyframes = new KeyframeEffect(
  whiteRabbit,
  [{ transform: "translateY(0%)" }, { transform: "translateY(100%)" }],
  { duration: 3000, fill: "forwards" },
);

const rabbitDownAnimation = new Animation(rabbitDownKeyframes);
