[edit] Summary

Returns the deepest Node that contains the startContainer and endContainer Nodes.

[edit] Syntax

rangeAncestor = range.commonAncestorContainer;

[edit] Example

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

[edit] Notes

Returns the deepest, or further down the document tree, Node that contains both the startContainer and endContainer nodes. Since a Range need not be continuous, and may also partially select Nodes, this is a convenient way to find a Node which encloses a Range.

This property is read-only. To change the ancestor container of a Node, consider using the various methods to set the start and end positions of the Range.
