getComputedTiming() 方法在 AnimationEffect interface returns the calculated timing properties for this animation effect.

Although many of the attributes of the returned object are common to the EffectTiming contained in the object returned by the AnimationEffect.getTiming() method, the values returned by this object differ in the following ways:

duration

Returns the calculated value of the iteration duration. If EffectTiming.duration is the string auto , this attribute will return 0 .

fill

auto value is replaced with the appropriate EffectTiming.fill 值。

These values are comparable to the computed styles of an Element returned using window.getComputedStyle(elem) .

句法

var currentTimeValues = animation.getComputedTiming();
					

参数

None.

返回值

A ComputedEffectTiming dictionary object, which contains the following properties:

endTime

The end time of the animation in milliseconds from the animation's start (if the KeyframeEffect is associated with an 动画 ). (Also includes EffectTiming.endDelay in that calculation.)

activeDuration

The length of time in milliseconds that the animation's effects will run. This is equal to the iteration duration multiplied by the iteration count .

localTime

current time of the animation in milliseconds. If the KeyframeEffect is not associated with an 动画 , its value is null .

progress

Indicates how far along the animation is through its current iteration with values between 0 and 1 。返回 null if the animation is not running or its KeyframeEffect isn't associated with an 动画 .

currentIteration

The number of times this animation has looped, starting from 0 . Returns null if the animation is not running or its KeyframeEffect isn't associated with an 动画 .
