Copying the contents of an i-frame

[jovialjonny]

hi,
I have got an iframe that is being targeted by a form. So the form submits to a servlet and the resulting page loads in this iframe.

What I want to do is create another iframe containing exactly the same thing (So the data in the form can be analysed by users in a split screen). I have had no problem duplicating the iframe for regular web pages like so:

var ifrm = document.createElement("IFRAME");
ifrm.id = "f"+reverseId;
ifrm.scrolling = "Auto";
//THE FRAME I AM COPYING
var origIfrm = document.getElementById("f"+tabId);
//SET THE SRC TO BE THE SAME
ifrm.src = origIfrm.src;
document.body.appendChild(ifrm);

If the iframe contained, say google, this works fine but when I try it with the data returned from the form I just get a blank page.

The iframe containing the form seems to have no 'src' or 'location' or 'innerHTML' that I can reference. Does anyone know how can I get the content of the iframe and put it into this new iframe I have created?

Post a link...
If the servlet returning values is served fromt he same server where your pages are then thene should be no problem

I can't post a link because I only have intranet access right now but I am holding all my files...the HTML, JavaScript and Servlet class files in the same directory on my local machine which is using a Microsoft IIS server.

I don't really know too much about servers to be honest because I'm a bit of a newbie but you think that by just setting the 'src' attribute of the new frame to be the same as the old that should work?

Im using JRun 4 to run the servlets, I have it configured to work with IIS. To be honest I didn't do it myself so I'm unsure what the exact setup is but they do run on the same server as far as I am aware. Have you any idea what could be wrong? The 'src' and 'innerHTML' are empty and the 'location' comes back as undefined so I am running out of ideas for getting the content to display in the new frame.

Oh ok..I know JRun can be configured with an array of http webservers..

Ok when this page comes back from the servlet,can you view the src?

[jovialjonny]

No I can't view the'src', if I put an alert on it it comes up blank, I tried setting the location to be the same (newFrame.location = oldFrame.location) and a few other things but have had no luck as yet.
