iframe's DOM

Need help on manipulating the DOM of a document within an iframe

[paul411]

Hi,

What i basically want to do is to manipulate or access the DOM of a document within an iframe.

So far, I've tried this on orkut's homepage (to access the iframe containing the Google Accounts Login)

As entered in FireFox's address bar:

javascript:alert(window.frames[0].document.getElementById('t').innerHTML); void(0);

If I try this, I get the following error (in the Error Console):

Error: uncaught exception: Permission denied to get property HTMLDocument.getElementById

How can I access and modify the DOM of an iframe?

The IFRAME src has to be of the same domain as the parent for JS to work across frames. Same with framesets.
