This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
direction property of the
AnimationEffectTimingReadOnly dictionary object represents the direction of the animation's playback along its timeline and its behavior after completing each iteration.
// Getting the direction of the animation var animationPlaybackDirection = animation.effect.timing.direction; // Setting the direction of the animation animation.effect.timing.direction = reverse;
DOMString representing the direction of the animation's playback. It can take one of the following values (defaults to
- The animation runs forwards, from beginning to end, in the way we experience the flow of time.
- The animation runs backwards, or "rewinds."
- The animation switches direction after each iteration, going from forwards to backwards then back again every two iterations.
- The reverse of the above: the animation switches direction after each iteration, going from backwards to forwards then back again every two iterations.
In the Red Queen's Race example, we can inspect the Red Queen and Alice's animation to discover a production secret:
// Returns "reverse" because the sprite was created upside down! return redQueen_alice.effect.timing.direction;
The definition of 'AnimationEffectTimingReadOnly.direction' in that specification.
