{{ SeeCompatTable() }} {{ APIRef("Web Animations API") }}
The AnimationEffectTiming
interface of the Web Animations API is a dictionary object of timing properties returned by the timing
attribute of a {{domxref("KeyframeEffect")}}. It inherits its properties from {{domxref("AnimationEffectTimingReadOnly")}}. The difference being that these aren't read only.
Syntax
var animationDuration = animation.effect.timing.duration;
Properties
_This interface inherits its property from its parent, {{domxref("AnimationEffectTimingReadOnly")}}._
- {{domxref("AnimationEffectTimingReadOnly.delay")}} {{readonlyInline}}
- The number of milliseconds to delay the start of the animation. Defaults to
0
. - {{domxref("AnimationEffectTimingReadOnly.endDelay")}} {{readonlyInline}}
- The number of milliseconds to delay after the end of an animation. This is primarily of use when sequencing animations based on the end time of another animation. Defaults to
0
. - {{domxref("AnimationEffectTimingReadOnly.fill")}} {{readonlyInline}}
- Dictates whether the animation's effects should be reflected by the element(s) prior to playing (
backwards
), retained after the animation has completed playing (forwards
), orboth
. Defaults tonone
. - {{domxref("AnimationEffectTimingReadOnly.iterationStart")}} {{readonlyInline}}
- Dictates whether the animation's effects should be reflected by the element(s) prior to playing (
backwards
), retained after the animation has completed playing (forwards
), orboth
. Defaults tonone
. - {{domxref("AnimationEffectTimingReadOnly.iterations")}} {{readonlyInline}}
- The number of times the animation should repeat. Defaults to
1
, and can also take a value of infinity to make it repeat infinitely. - {{domxref("AnimationEffectTimingReadOnly.duration")}} {{readonlyInline}}
- The number of milliseconds each iteration of the animation takes to complete. Defaults to
0
. - {{domxref("AnimationEffectReadOnly.direction")}} {{readonlyInline}}
- Whether the animation runs forwards (
normal
), backwards (reverse
), switches direction after each iteration (alternate
), or runs backwards and switches direction after each iteration (alternate-reverse
). Defaults tonormal
. - {{domxref("AnimationEffectTimingReadOnly.easing")}} {{readonlyInline}}
- The rate of the animation's change over time. Accepts the pre-defined values
linear
,ease
,ease-in
,ease-out
, andease-in-out
, or a custom cubic-bezier value likecubic-bezier(0.42, 0, 0.58, 1)
. Defaults tolinear
.
Examples
In the Growing and Shrinking Alice example, we set Alice's animation, aliceChange
at halfway complete by getting the duration of its effect
's timing
attribute, which is an AnimationEffectTiming
object:
aliceChange.currentTime = aliceChange.effect.timing.duration / 2 ;
