这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

getKeyframes() method of a KeyframeEffect returns an Array of the computed keyframes that make up this animation along with their computed offsets.

句法

var keyframes = keyframeEffect.getKeyframes();
					

参数

None.

返回值

Returns a sequence of objects with the following format:

property value pairs

As many property value pairs as are contained in each keyframe of the animation.

offset

The offset of the keyframe specified as a number between 0.0 and 1.0 inclusive or null . This is equivalent to specifying start and end states in percentages in CSS stylesheets using @keyframes . This will be null if the keyframe is automatically spaced using KeyframeEffect.spacing .

computedOffset

The computed offset for this keyframe, calculated when the list of computed keyframes was produced according to KeyframeEffect.spacing . Unlike offset , above, the computedOffset is never null .

easing

timing function used from this keyframe until the next keyframe in the series.

composite

KeyframeEffect.composite operation used to combine the values specified in this keyframe with the underlying value. This will be absent if the composite operation specified on the effect is being used.

范例

在 Red Queen Race example, we can inspect Alice and the RedQueen's animation to see its individual keyframes like so:

// Return the array of keyframes
redQueen_alice.effect.getKeyframes();
