This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The IntersectionObserverEntry
interface's read-only target
property indicates which targeted Element
has changed its amount of intersection with the intersection root.
Syntax
var target = IntersectionObserverEntry.target;
Value
The IntersectionObserverEntry
's target
property specifies which Element
previously targeted by calling IntersectionObserver.observe()
experienced a change in intersection with the root.
Example
In this simple example, each targeted element's opacity
is set to its intersectionRatio
.
function intersectionCallback(entries) {
entries.forEach(function(entry) {
entry.target.opacity = entry.intersectionRatio;
});
}
To see a more concrete example, take a look at Handling intersection changes in Timing element visibility with the Intersection Observer API.
