I have a site using JQuery and a PrettyPhoto lightbox to create a pop-up box with an iFrame to display a form on a different page on the site. You can see a screenshot here: http://174.132.166.253/~sharedgr/GeneralGraphics/2012-02-07_1324.png I want to be sure visitors submit the form before closing the box. I need to detect what page is loaded in the PrettyPhoto iFrame and if the "thank you" page is not loaded, clicking on the close button will display a JavaScript confirmation box telling them they have not submitted their info and ask if they really want to close it. I can add code to the Thank You page if needed. If the Thank You page is loaded, I do not want the alertbox to pop up. It is a modified version of PrettyPhoto and JQuery which was provided with my site template. I need for this to work really well in both IE and FireFox. I need it done today. It should be an easy job for someone good at JavaScript. I will give you the source js files and you can send them back. I don't want to give FTP access for this project.
