这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

DocumentTimeline() constructor of the Web 动画 API creates a new instance of the DocumentTimeline object associated with the active document of the current browsing context.

句法

var sharedTimeline = new DocumentTimeline(options);
					

参数

选项

An object specifying options for the new timeline. Currently the only supported option is the originTime member which specifies the zero time for the documentTimeline as a real number of milliseconds relative to the navigationStart moment of the active document for the current browsing context.

范例

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();
});
