This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The IntersectionObserverEntry
interface's read-only time
property is a DOMHighResTimeStamp
that indicates the time at which the intersection change occurred relative to the time at which the document was created.
Syntax
var time =
IntersectionObserverEntry.time;
Value
A DOMHighResTimeStamp
which indicates the time at which the target
element experienced the intersection change described by the IntersectionObserverEntry
. The time is specified in milliseconds since the creation of the containing document.
Example
See Timing element visibility with the Intersection Observer API for a complete example which uses the time
property to track how long elements are visible to the user.
