Complete javascript after call to PayPal

What is the best way to implement a call to PayPal so that after a customer completes the payment process, they are then directed back to the original site where the rest of the javascript can continue?

Perhaps I am not even thinking of this problem in the right terms Basically I want some javascript code to run, but only after a successful PayPal payment has been completed.

Here is the code for the call to PayPal:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
  <input type="hidden" name="cmd" value="_s-xclick">
  <input type="hidden" name="hosted_button_id" value="123456789">
  <input type="image"
      src="https://www.paypalobjects.com/en_US/i/btn/btn_paynow_SM.gif"
      border="0" name="submit"
      alt="PayPal - The safer, easier way to pay online!">
  <img alt="" border="0"
      src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1"
      height="1">
</form>

Open in new window

Any ideas or best practices for me to consider? Thanks.

when you create your form(button) with paypal, you have the possibility to set this URL in the step two.
You can use the same url/page and add a parameter in the url
or use a different page

Great points angelleye. I hadn't thought about the possibility of the user not making it to the return URL. In my particular use-case, I absolutely need my javascript code to run at the moment the payment is processed on PayPal. I will start reading-up on IPN.
Thanks.
