Range: collapsed property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.

The Range.collapsed read-only property returns a boolean flag indicating whether the start and end points of the Range are at the same position. It returns true if the start and end boundary points of the Range are the same point in the DOM, false if not.

A collapsed Range is empty (containing no content), and specifies a single point in a DOM tree. To collapse a range, see the Range.collapse() method.

Value

A boolean.

Examples

js
let range = document.createRange();

range.setStart(startNode, startOffset);
range.setEnd(endNode, endOffset);
isCollapsed = range.collapsed;
