Please don't top-post. I've corrected it above.
Also, Javascripting a critical part of a website is always a Bad
Idea. Many people, such as myself, have browsers that don't support
Javascript. Many people disable Javascript in their browsers to
avoid popups, ads, etc.
A better solution to this would be to create a confirmation page
for the credit card purchase which has an additional submit button
that goes only to the credit card company.
The confirmation page can be the invoice page, except that it checks
which button was clicked and either displays an invoice or a
confirmation (or both).
