Javascript running in facebox window

I'开发者_JAVA技巧m modifying a website to have a pop up box appear when a user rates something prompting the user to login. Unfortunately the login process is something that I don't control and it uses a whole heap of javascript and redirects to do it and it seems that the javascript is failing.

Can javascript run in the modal box or is there a way around this?

You could try isolating the JavaScript by putting it in an inline frame [iFrame] on a separate html document

Just a thought. Haven't tested it.
