Passing data back to Parent from IFrame

[NeeNee]

I need to validate a customer number on a Purchase requisition form. I am trying to use an IFrame to retrieve the vendor info and pass it back to the parent form. I can get the IFrame source ASP page to get the record, but I can seem to access the parent object from within the IFrame. I tried parent.parent, parent.top and parent.document, but they all say they can't find the object.

What am I missing? Is it no possible to access the parent from an Iframe? Is there security involved?

Thanks

You can reference the Parent through an iframe with window.opener I'm pretty sure (not 100% sure).

Are the two pages coming from different (according to the browser) domains? If your parent page URL is

http://intranet.mycompany.com/mywebapp.html

and your iframe is loading up

http://192.168.200.50/customerinfo.asp,

then regardless of whether the two addresses actually point to the same box or not, the browser will interpret it as an attempt at cross-domain scripting.

Both pages are in the same directory. The main page passes the vendor number through the iFrame ulr. The iFrame ASP page takes the vendor number from the querystring and retreives the vendor record if there is one. My page currently displays the vendor record correctly. I am just trying to find a way to pass the information back to the main page. I will then hide the iframe page and make the validation transparent to the user.
