Standards information

Remarks

The IHTMLDOMNode::cloneNode method copies an object, attributes, and, if specified, the childNodes.

When you refer to the IHTMLElement::id of a cloned element, a collection is returned.

IHTMLDOMNode::cloneNode does not work on an IFRAME directly. You must call IHTMLDOMNode::cloneNodethrough the all collection. The following example demonstrates how to call IHTMLDOMNode::cloneNode on an IFRAME.

<!DOCTYPE html>
<html>

<head>
  <title>&lt;iframe&gt;</title>
</head>

<body onload="fnBegin()">
  <iframe id="oFrame" src="about:blank" style="border: 1px solid black; position: absolute; top: 20px; left: 30px; width: 350px; height: 300px;"></iframe>
  <script>
    function fnBegin() {
      var fr = document.all.oFrame.cloneNode();
      console.log(document.body.innerHTML);
    }
  </script>
</body>

</html>

If the object being cloned is an element and that element has expandos defined on it, the expandos are copied to the clone when IHTMLDOMNode::cloneNode is called. Other browsers might handle this differently.

In Microsoft Internet Explorer 6, this method applies to the attribute object.
