startOffset

---

Returns a number representing where in the startContainer the Range starts.

Syntax

startRangeOffset = range.startOffset;

Parameters

startRangeOffset is the number characters or a child Node index where the Range starts in the startContainer

Example

range = document.createRange(); range.setStart(startNode,startOffset); range.setEnd(endNode,endOffset); startRangeOffset = range.startOffset;

Notes

startOffset has two meanings. If the startContainer is a Node of type Text, Comment, or CDATASection, then the offset is the number of characters from the start of the startContainer to the boundary point of the Range. For other Node types, the startOffset is the number of child nodes between the start of the startContainer and the boundary point of the Range. This property is read-only. To change the startOffset of a Range, use one of the setStart methods.
