This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The Selection.anchorOffset read-only property returns the number of characters that the selection's anchor is offset within the Selection.anchorNode.
This number is zero-based. If the selection begins with the first character in the Selection.anchorNode, 0 is returned.
Syntax
number = sel.anchorOffset
