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


<var>document</var> = <var>element</var>.ownerDocument
  • document is the document object parent of the current element.


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

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


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.

[1] Starting in Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6), the ownerDocument of doctype nodes (that is, nodes for which Node.nodeType is Node.DOCUMENT_TYPE_NODE or 10) is no longer null. Instead, the ownerDocument is the document on which document.implementation.createDocumentType() was called.
