Node.ownerDocument

The Node.ownerDocument read-only property returns the top-level document object for this node.

Syntax

document = element.ownerDocument

document is the document object parent of the current element.

Example

// given a node "p", get the top-level HTML child 
// of the document object

var d = p.ownerDocument; 
var html = d.documentElement;

Notes

The document object returned by this property is the main object with which all the child nodes in the actual HTML document are created. If this property is used on a node that is itself a document, the result is null.
