js
getKeyframes()
None.
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
The easing function used from this keyframe until the next keyframe in the series.
composite
The 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.
In the Red Queen Race example, we can inspect Alice and the RedQueen's animation to see its individual keyframes like so:
js
// Return the array of keyframes redQueen_alice.effect.getKeyframes();
