Javascript help

[Kieran G]

I want to put an iframe in a HTA file, I want is so that when someone clicks a link inside the iframe that isn't pointing to somewhere on my site a javascript prompt will pop up asking for a password, I know that it's not secure to use a JS prompt but I just need help doing the script, anyone?
