AnimationEvent.initAnimationEvent() - Web APIs 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Summary

The AnimationEvent.initAnimationEvent() method Initializes an animation event created using the deprecated Document.createEvent("AnimationEvent") method.

AnimationEvent created this way are untrusted.

Note: During the standardization process, this method was removed from the specification. It has been deprecated and is in the progress of being removed from most implementations. Do not use this method; instead, use the standard constructor, AnimationEvent(), to create a synthetic AnimationEvent.

Syntax

animationEvent.initAnimationEvent(typeArg, canBubbleArg, cancelableArg, animationNameArg, elapsedTimeArg);

Parameters

typeArg

A DOMString identifying the specific type of animation event that occurred. The following values are allowed:

Value	Meaning
animationstart	The animation has started.
animationend	The animation completed.
animationiteration	The current iteration just completed.

canBubbleArg

A Boolean flag indicating if the event can bubble (true) or not (false).

cancelableArg

A Boolean flag indicating if the event associated action can be avoided (true) or not (false).

animationNameArg

A DOMString containing the value of the animation-name CSS property associated with the transition.

elapsedTimeArg

A float indicating the amount of time the animation has been running, in seconds, as of the time the event was fired, excluding any time the animation was paused. For an "animationstart" event, elapsedTime is 0.0 unless there was a negative value for animation-delay, in which case the event will be fired with elapsedTime containing  (-1 *delay).
