This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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(options);
Parameters
- options
- An object specifying options for the new timeline. Currently the only supported option is the
originTime
member which specifies the zero time for thedocumentTimeline
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({ originTime: 500 }); cats.forEach(function(cat) { var catKeyframes = new KeyframeEffect(cat, keyframes, timing); var catAnimation = new Animation(catKeyframes, sharedTimeline); catAnimation.play(); });
