how to refer to an iframe's parent doc?

[Govinda]

Hi all

How can I make a form submission inside an iframe (iframe submitting
to itself) cause it's wrapper a <div>, in the iframe's *parent doc*,
to get its CSS display: set to 'none'? Is there a way to refer to an
iframe's parent with JS or HTML?

Or how would you approach this? I want to use an iframe rather than a
JS popup window if possible.. but will relent if utterly necessary.

thanks

now I know I can call a JS function in the parent doc with:
parent.functionName
(in case anyone was curios how it got solved.)
wishing you well
