Selection: anchorOffset property

{{ ApiRef("DOM") }}

The Selection.anchorOffset read-only property returns the number of characters that the selection's anchor is offset within the {{domxref("Selection.anchorNode")}} if said node is of type {{domxref("Text")}}, {{domxref("CDATASection")}} or {{domxref("Comment")}}.

In the case of {{domxref("Selection.anchorNode")}} being another type of node, Selection.anchorOffset returns the number of {{domxref("Node.childNodes")}} the selection's anchor is offset within the {{domxref("Selection.anchorNode")}}.

This number is zero-based. If the selection begins with the first character in the {{domxref("Selection.anchorNode")}}, 0 is returned.

Value

A number.
