What's New for Microsoft® Internet Explorer 6
This method applies to the
Syntax
oClone = object.cloneNode( [bCloneChildren])Parameters
bCloneChildren Optional. Boolean爐hat specifies one of the following values:
false Default. Cloned objects do not include childNodes. true Cloned objects include childNodes.
Return Value
Returns燼 reference to the newly created node.
Remarks
The cloneNode method copies an object, attributes, and, if specified, the childNodes.
A collection is returned when referring to the ID of a cloned element.
The cloneNode method will not work on an IFRAME directly. You must call it through the all collection. The following example demonstrates how to call cloneNode on an IFRAME.
<HTML> <SCRIPT> function fnBegin(){ var fr = document.all.oFrame.cloneNode(); alert(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>
Example
<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()">Standards Information
