Pop up blocked or not?

[sali63m]

Let me ask my question as an example:

 

I have a site named mysite.com

I give you a code to place on your site and when a visitor sees your site, a pop up appears (which is a page defined in mysite.com/popup.php)

your code is : <script language=JavaScript src=http://www.mysite.com/popup.php?id=x></script>

 

and for each unique visitos you get 1 point by me.

 

The problem is this: when someone that has popup blocker visits your site he doesnt see the popup but you get 1 point.

 

How can i prevent this? and how can i define whether popup executed or not?

I think this question is more Javascript, or even AJAX related then plain PHP.
