blocking ad blocker software

[mmatthew]

Customers using our site are complaining that parts of it, such as pop up windows, do not work when they use ad blocker software. I would like to be able to detect this software and display a message to turn it off when using our site.

any other info on how to deal with site problems caused by ad blocker software is appreciated.

Ad blockers block the window.open function, so what you need to make is a script on the first page of your site which tries to open a window. When this window opens, it needs to define a variable which it will return to the original window. The script can then prompt the user to disable ad-blockers if that variable is never returned. I'm a bit busy to script that, but maybe someone else could?

It's the responsibility of the web author to follow the standards and make pages that work when pop-ups are blocked or when scripting is disabled. And it's easily done. If you use the following method to open your pop-ups you will stop getting those complaints.

Thanks Charles, but what if I am not doing an anchor tag?

What are you doing?

[mmatthew]

our site automatically pops up windows under certain conditions. an example
<script language="JavaScript">
var url = "http://www.goinghere.com/thispage";
window.open(url,"win");
top.location.href ="#system##linkString#";
</script>

I need a little more to go on than that, but there's always a way. You just have to get creative. Sometimes the best way to work is to start with a site that works without JavaScript and then add. Flashing to people who know that they're blocking your pop-ups a notice that they're blocking your pop-ups is only going to anger the people who are currently annoyed.
