Report feedback
The read-only
collapsed
property of the
AbstractRange
interface returns
true
if the range's start position and end position are the same.
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 value which is
true
if the range is
collapsed
. A collapsed range is one in which the start and end positions are the same, resulting in a zero-character-long range.
Example
js
const range = document.createRange();
range.setStart(startNode, startOffset);
range.setEnd(endNode, endOffset);

const isCollapsed = range.collapsed;
