Report feedback
The
endOffset
property of the
AbstractRange
interface returns the offset into the end node of the range's end position.
To change the end position, use the
Range.setEnd()
method or a similar one.
Value
An integer value indicating the number of characters into the
Node
indicated by
endContainer
at which the final character of the range is located.
If the
endContainer
is a
Node
of type
Text
Comment
, or
CDATASection
, then the offset is the number of characters from the start of the
endContainer
to the boundary point of the range. For other
Node
types, the
endOffset
is the number of child nodes between the start of the
endContainer
and the boundary point of the range.
Example
js
const range = document.createRange();
range.setStart(startNode, startOffset);
range.setEnd(endNode, endOffset);

const endRangeOffset = range.endOffset;
