Iframe question

[mike]

I have a document lets call it a.cfm that looks like:

<iframe src="" id="test" name="test"></iframe>

<div>
<form name="myform">
... many elements here
</form>
</div>

I open up a.cfm and my js changes the src of the iframe on the fly
between a couple different scripts lets call them x.cfm and y.cfm

2 questions:

1) In x.cfm I want to access the form elements in "myform".
Of course neither of these work:
if ( self.opener.document.myform.elements[] )
if ( document.myform.elements[] )

2) In x.cfm I want to see what parent iframe I opened up.
This doesn't work:
if (document.getElementByID('test') )

Can I not point inside either document I open up?

Yes, you can. This thread should help:

Of course not as test isn't in x.cfm

parent.document........

That depends on what you are calling "point insided either document".
