elsewhere home of a .NET geek

I was facing an strange error (Grrrrr!! I can't say it is an error!!) while testing an page with IE and FF. The deal is i have an IFRAME sitting a Page and i have to read the values of the textboxes present in the IFRAME from the page. The following code worked fine in IE but not in FF

        var _email  = document.frames[0].document.getElementById('emailAddress');

I got pissed off for a while to identify the proper code, the solution is as below which worked in both IE and FF,

var iFrame = parent.frames[0]; //Get the IFRAME         

var _email  = iFrame.document.forms[0].elements['emailAddress']; 
// then, locate the textbox using the 'element' object

Let me see, if any body can post more better script :)
