How to apply "cloneNode()" on NS7?

**Lotfi Abdolhal** · 09-22-2004, 03:52 AM

Hello every body!
The following script works OK for ie6, but I do not know how to modified to make it work on ns7.
In other words, how may I cloneNode an IFRAME object with ns7?

PHP Code:


<HTML>

<SCRIPT>

function Begin(){

   FR= document.all.IFRM.cloneNode(); attribs="";

   for(at=0; at < FR.attributes.length; at++)

     if(FR.attributes[at].specified == true) attribs+= FR.attributes[at].name+"\n";

   alert(attribs);

}    

</SCRIPT>

<BODY onload="Begin()">

   <IFRAME id="IFRM" src="about:blank" style="border:1px solid black; position:absolute; top:20px; left:30px; width:350px; height:300px;">

</IFRAME>

</BODY>    

</HTML>

your code fails because Moz doesn't support IE's proprietory document.all collection!

to access the iframe, you need to use the document.getElementById method, which, as of version 5+ browsers, is cross-browser compatible.

Thanks Dear jbot for trying to help.

What you have noted is correct and I know it, but by changing the statement:
"FR= document.all.IFRM.cloneNode();"
to:
"FR= document.getElementById("IFRM").cloneNode();"
the script still fails on NS7, giving me the following error message - which I am not able to benefit thereof:
Error: uncaught exception: [Exception... "Not enough arguments [nsIDOMHTMLIFrameElement.cloneNode]"!

Do you know what should I do accordingly?
Thanks.

that's because you probably can't clone a frame, iframe or otherwise. what exactly are you trying to achieve - it may be better to use a full CSS layout instead.

Thank you very much indeed Dear jbot!

I will try again utilizing your advice.
have a good day.
