« DOM Reference « Range

The Range.setEnd() method sets the end position of a Range.

If the endNode is a Node of type Text, Comment, or CDATASection, then endOffset is the number of characters from the start of endNode. For other Node types, endOffset is the number of child nodes between the start of the endNode.

Setting the end point above (higher in the document) the start point will throw an ERROR_ILLEGAL_VALUE DOMException.


range.setEnd(endNode, endOffset);


The Node where the Range should end.
An integer greater than or equal to zero representing the offset for the end of the Range from the start of endNode.


range = document.createRange();
endNode = document.getElementsByTagName("p").item(3);
endOffset = document.getElementsByTagName("p").item(3).childNodes.length;
