The IntersectionObserverEntry
interface of the Intersection Observer API describes the intersection between the target element and its root container at a specific moment of transition. Instances of IntersectionObserverEntry
are delivered to an IntersectionObserver
callback in its entries
parameter; otherwise, these objects can only be obtained by calling IntersectionObserver.takeRecords()
.
Properties
IntersectionObserverEntry.boundingClientRect
Read only- Returns the bounds rectangle of the target element as a
DOMRectReadOnly
. The bounds are computed as described in the documentation forElement.getBoundingClientRect()
. IntersectionObserverEntry.intersectionRatio
Read only- Returns the ratio of the
intersectionRect
to theboundingClientRect
. IntersectionObserverEntry.intersectionRect
Read only- Returns a
DOMRectReadOnly
representing the target's visible area. IntersectionObserverEntry.isIntersecting
Read only- A Boolean value which is
true
if the target element intersects with the intersection observer's root. If this istrue
, then, theIntersectionObserverEntry
describes a transition into a state of intersection; if it'sfalse
, then you know the transition is from intersecting to not-intersecting. IntersectionObserverEntry.rootBounds
Read only- Returns a
DOMRectReadOnly
for the intersection observer's root. IntersectionObserverEntry.target
Read only- The
Element
whose intersection with the root changed. IntersectionObserverEntry.time
Read only- A
DOMHighResTimeStamp
indicating the time at which the intersection was recorded, relative to theIntersectionObserver
's time origin.
