ウェブアニメーション API の Animation() コンストラクタは新たに Animation オブジェクトのインスタンスを返します。

Syntax

var animation = new Animation([effect][, timeline]);

Parameters

effect 省略可
The target effect, as an object based on the AnimationEffectReadOnly (en-US) 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 (en-US). This can be null (which is the default) to indicate that there should be no effect applied.
timeline 省略可
Specifies the timeline with which to associate the animation, as an object of a type based on the AnimationTimeline (en-US) interface. Currently the only timeline type available is DocumentTimeline (en-US), but in the future there my be timelines associated with gestures or scrolling, for example. The default value is Document.timeline (en-US), but this can be set to null as well.

Examples

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

var rabbitDownAnimation = new Animation(rabbitDownKeyframes, document.timeline);
