Remarks

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

When you refer to the ID of a cloned element, a collection is returned.

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


<HTML>
<SCRIPT>
function fnBegin(){
    var fr = document.all.oFrame.cloneNode();
    console.log(document.body.innerHTML);
}    
</SCRIPT>
<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>
</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 cloneNode is called. Other browsers might handle this differently.

Examples


<SCRIPT>
function fnClone(){
   /* the 'true' possible value specifies to clone
      the childNodes as well.
   */
   var oCloneNode = oList.cloneNode(true);
   /* When the cloned node is added,
   'oList' becomes a collection.
   */
   document.body.insertBefore(oCloneNode);
}
</SCRIPT>
<UL ID="oList">
<LI>List node 1
<LI>List node 2
<LI>List node 3
<LI>List node 4
</UL>
<INPUT type="button" value="Clone List" onclick="fnClone()">
