How do I get javascript passed through an iframe to call a method loaded from an ajax response?

Hey experts,

First off, let me say that my code uses the Mootools 1.2 framework, and I'm still pretty green with JS so this might be a simple thing to fix...

Pretty much, I have a profile page where users can edit their data by clicking a link in the section, and it populates the form into a div with AJAX via Request.HTML.  Some of the forms are multiple pages, but they are all contained in that div.  The issue I am having is on one of the pages, there is a photo upload part that makes use of AJAX and an iframe.  The uploading part works fine in all browsers, but the javascript passed through the iframe on the response doesn't play well with IE(7 for sure) but FF is ok with it.  Visual Studio debugs it as "Object doesn't support this property or method" while Google Chrome says "Object [object global] has no method 'setPhoto'".  I'm thinking it has to do with the scope of it, and the fact that the js in the ajax was loaded after the dom was loaded. The code I am passing from the iframe is :

window.parent.setPhoto('6FB2A38DC107EACB');

I've tried window.top.window.setPhoto() parent.setPhoto(), but I can't get any of them to access that method that is loaded in the ajax.  Could someone please get me pointed in the right direction?

Thanks a bunch!

you mean there is a script in the response you want to execute?
If you do, you need to eval it since dropping it into some div's innerHTML does not execute it.
Alternatively try to add the script to the DOM - there are quite a few examples on the net on
ondemand script dom

With using mootools 1.2 Request.HTML can and will automatically eval your scripts.  The issue is that the scope of the first script with the function definition doesn't seem to be loaded in the same scope as the second script that loads in the ajax windo where the function call is placed.  The way I fixed it was to place the function def in the DOM, so it was global and accessible for all subsequential requests.  Thanks for the help!

Placing the function in the dom fixed the issue.
