DHTML exit pop script

I have a sales page and when a customer leaves the page? before purchasing, I want a DHTML window to display darkening out the rest of the page so the customer's focus turns to the DHTML window.? The DHTML window should not display if the user submits the payment form.? I want it to behave just like [[login to view URL]][1] (see demo on the page) but I don't need the dynamic chat features in the popup, just static content. This should not be a [login to view URL]() popup, but a layer that is not displayed until the page unloads.? ? Also, the DHTML popup will need to have a link in it to make the page click over another page - the page? from which the DHTML layer is displayed will need to change to the target of the ahref in the link in the DHTML layer. ## Deliverables I am looking for this to be completely quickly.
