How to make 2 windows open up when form submit button is pressed?

Question

I need to make it so when someone clicks the 'Pay' button on my form 2 windows open up.
I need this as when they click 'Pay' it should goto a paypal payment form, which it does. But i also need them to see a window they says "Payment complete, thankyou" from my site as well as paypal.
Help?

Use javascript. Intercept the form submit and call a function. The function will look like this:

function submitRequest() {
window.open("http://webaddress/pagetopopopen");
document.forms[0].submit();
}

The submit will handle the processing; the thank you will pop up whether it sucessfully processes or not.
