This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The timeline
readonly property of the Document
interface represents the default timeline of the current document. This timeline is a special instance of DocumentTimeline
that is automatically created on page load.
This timeline is unique to each document
and persists for the lifetime of the document
including calls to Document.open()
.
The time values for this timeline are calculated as a fixed offset from the global clock such that the zero time corresponds to the navigationStart
moment plus a signed delta known as the origin time. Prior to establishing the navigationStart
moment, the document timeline is inactive.
Note: A document timeline that is associated with a non-active document is also considered to be inactive.
Syntax
var pageTimeline = document.timeline; var thisMoment = pageTimeline.currentTime;
Value
A DocumentTimeline
object.
