The Selection.focusOffset read-only property returns the number of characters that the selection's focus is offset within the Selection.focusNode if said node is of type Text, CDATASection or Comment.

In the case of Selection.focusNode being another type of node, Selection.focusOffset returns the number of Node.childNodes the selection's focus is offset within the Selection.focusNode.

This number is zero-based. If the selection ends with the first character in the Selection.focusNode, 0 is returned.

Value
