AnimationEffectTimingReadOnly

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The AnimationEffectTimingReadOnly interface of the Web Animations API is comprised of timing properties.

This object is returned by the timing attribute of a KeyframeEffectReadOnly and AnimationEffectReadOnly interfaces. 

While this object is read-only, it is inherited by the mutable AnimationEffectTiming interface associated with KeyframeEffect.

Properties

AnimationEffectTimingReadOnly.delayRead only
The number of milliseconds to delay the start of the animation. Defaults to 0.
AnimationEffectTimingReadOnly.directionRead only
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 to normal.
AnimationEffectTimingReadOnly.durationRead only
The number of milliseconds each iteration of the animation takes to complete. Defaults to 0.
AnimationEffectTimingReadOnly.easingRead only
The rate of the animation's change over time. Accepts the pre-defined values linear, ease, ease-in, ease-out, and ease-in-out, or a custom cubic-bezier value like cubic-bezier(0.42, 0, 0.58, 1). Defaults to linear.
AnimationEffectTimingReadOnly.endDelayRead only
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.
AnimationEffectTimingReadOnly.fillRead only
Dictates whether the animation's effects should be reflected by the element(s) state prior to playing (backwards), retained after the animation has completed playing (forwards), or both. Defaults to none.
AnimationEffectTimingReadOnly.iterationStartRead only
A number representing which repetition the animation begins at and its progress through it.
AnimationEffectTimingReadOnly.iterationsRead only
The number of times the animation should repeat. Defaults to 1, and can also take a value of infinity to make it repeat infinitely.

1. The preference is set to true by default on Firefox Nightly and on Firefox Developer Edition, but not on the official release.

2. From version 45: this feature is behind the dom.animations-api.core-enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.

3. From version 48: this feature is behind the dom.animations-api.core-enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.
