Zen Cart 1.3.8a
Patch: 1::
Database Patch Level: 1.3.8
New Install-no addons

I searched posts, not able to find anything on "unload"

I am wanting to put a "last chance" to buy pop-up window. It would pop-up when the user leaves the web site, not individual pages.

I have a script from an online site, I can make the pop-up appear when moving between pages in my web site, but I only want it to appear when they are leaving the web site.

My script requires a <body onunload> tag, I can insert an "onload" tag by inserting a on_load_*.js file. But Zen Cart wont recognize an "onunload". I only want the pop-up when unloading.

Anyway of doing this? I am not a whiz at scripting.

Thanks in advance for any direction on this.
