How to find a form element inside multiple frames using jquery
===

I am working on a website that currently uses the old style frames. I want to go through a replace some javascript DOM calls because I am running into cross-browser issues. This is what I would like to replace. 

    window.parent.frames['topdisplay'].document.FORMSV2DISPLAY.action = 'what ever action';

In the above code my problem is that the 'document.FORMSV2DISPLAY' part doesn't work in IE I have to replace that part with document.form(0) and then of course neither of those work correctly in Chrome or Safari. 

I would like to use jquery to find the form named FORMSV2DISPLAY and then perform my usual actions and submits.

I have tried things like 
    $(this).find('FORMSV2DISPLAY').action
    $(parent).find('FORMSV2DISPLAY').action
    $('topdisplay').find('FORMSV2DISPLAY').action

none of these return the same thing as the javascript DOM calls I am trying to replace. I am very new to jquery and help or understanding is greatly appreciated.
