range.commonAncestorContainer Redirect 1

« DOM Reference « Range

The Range.commonAncestorContainer read-only property returns the deepest, or further down the document tree, Node that contains both the Range.startContainer and Range.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.


rangeAncestor = range.commonAncestorContainer;


var range = document.createRange();

rangeAncestor = range.commonAncestorContainer;
