OK. I posted this in another thread a few days ago, but didn't get any reaction. Can a javascript guru take a look at this and see if (s)he can get this baby purring???

*******

In the header, I've put:

function nocj() {
document.images.nocjroute = new Image();
document.images.nocjroute.src ="http://example.com/images/nocj.gif";
}
// End -->
</script>

In one of the qksrv.net img tags on the page, I've added:

onError="nocj()"

So theoretically, if their browser can't contact qksrv.net, the javascript error routine is called, and the browser attempts to load the 'nocj.gif" image from my webserver, and I get a log entry recording that someone can't reach qksrv.net


I've tested it, and the error code, is called, but I can't get the image request to appear in my log file.

It's probably a simple error. Any suggestions?

If we can get this to work, we can get some fairly reliable stats about just how many surfers out there have a poisoned hosts file that is blocking affiliate networks.

If you know a javascript guru that can help, please send them to this thread!!!

Looks like a complete infuctuation to me....

!You didn't declare variable Image and you do nothing with it

document.images.nocjroute.src ="http://example.com/images/nocj.gif";

!See above...
}
// End -->

Thanks for that.

Now, can you posts a corrected version of the script?

Would it help if I added "name=nocjroute" to the image tag as well as the onerror() bit?

Well, what do you know?

I've been testing it in Netscape 7 all this time and could never get it to work.

Tried it in IE5.2/Mac and it appears to work fine.

I've set it up on a site, and it's reliably telling me when a surfer using IE cannot load qksrv.net images.

This should tell us - in general - that they have a poisoned hosts file that is blocking qksrv.net.

I'll let it run for 24 hours and then we'll see what the results are.

In the few minutes I've had it running, it's already detected 3 surfers that couldn't access Commission Junction.

Wow!
Nice work, Drewbert! This is exactly what I was hoping someone could figure out. Powerful stuff.
The other suggestion made in that thread earlier, to call an advisory page providing instructions for restoration of an unaltered hosts file would be the next step.
I know Andrew Clover's parasite advisory page has been invaluable to me.
Big Thanks to all who have worked on this one!

It would be great if someone could post the complete script as we have it now. Just for us newbies to javascript.
