[thelist] JAVASCRIPT and IFRAMEs [solved i think]

[Tom Dell'Aringa]

I believe Jeff got me in the right direction here.

With my little document set I made up to mimic yours, turns out the
iframe document itself is the opener. (Using opener.location.href to
find this out, kudos to jeff.)

So, I just did:

var x = window.opener.document.getElementById("sometext").value;

where "sometext" was a FIELD in my FORM (which is what you want
right?) and the value came over perfectly.

So as long as the link that is opening the popup is INSIDE the iframe
(and i thought you said it was) the opener is the Iframe - not the
document that holds it.

HTH.
