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.
The DocumentTimeline()
constructor of the Web Animations API creates a new instance of the DocumentTimeline
object associated with the active document of the current browsing context.
Syntax
var sharedTimeline = new DocumentTimeline(originTime);
Parameters
- originTime
- The zero time for the
documentTimeline
specified as a real number of milliseconds relative to thenavigationStart
moment of the active document for the current browsing context.
Examples
We could share a single documentTimeline
among multiple animations, thus allowing us to manipulate just that group of animations via their shared timeline. This bit of code would start all the cats animating 500 milliseconds into their animations:
var cats = document.querySelectorAll('.sharedTimelineCat'); cats = Array.prototype.slice.call(cats); var sharedTimeline = new DocumentTimeline(500); cats.forEach(function(cat) { var catKeyframes = new KeyframeEffect(cat, keyframes, timing); var catAnimation = new Animation(catKeyframes, sharedTimeline); catAnimation.play(); });
