IntersectionObserverEntry

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The IntersectionObserverEntry interface of the the Intersection Observer API provides information about the intersection of a particular target with the observers root element at a particular time. Instances of this interface cannot be created, but a list of them is returned by IntersectionObserver.takeRecords().

Properties

IntersectionObserverEntry.boundingClientRect Read only: Returns a DOMRectReadOnly for the intersection observer's target.
IntersectionObserverEntry.intersectionRatio Read only: Returns the ratio of the intersectionRect to the boundingClientRect.
IntersectionObserverEntry.intersectionRect Read only: Returns a DOMRectReadOnly for the visible portion of the intersection observer's target.
IntersectionObserverEntry.rootBounds Read only: Returns a DOMRectReadOnly for the intersection observer's root.
IntersectionObserverEntry.time Read only: Returns a DOMHightResTimeStamp indicating when the intersection occurred.
