IntersectionObserver.thresholds

The IntersectionObserver interface's read-only thresholds property returns the list of intersection thresholds that was specified when the observer was instantiated with IntersectionObserver(). If only one threshold ratio was provided when instanitating the object, this will be an array containing that single value.

See Thresholds in Intersection Observer API to learn how thresholds work.

Syntax

var thresholds = IntersectionObserver.thresholds;

Value

An array of intersection thresholds, originally specified using the threshold property when instantiating the observer. If only one observer was specified, without being in an array, this value is a one-entry array containing that threshold. Regardless of the order your original threshold array was in, this one is always sorted in numerically increasing order.

If no threshold option was included when IntersectionObserver() was used to instantiate the observer, the value of thresholds is simply [0].
