How to track a Google Adwords conversion onclick?

Question

Google Adwords offers no code to add to your page to count a conversion if somebody clicks on a link. But as it's Javascript, I am sure there is a way to do this.

Here's the code (unaltered) Google gives you to include in the page, that should count as a conversion (most of the time a thank you page):

<!-- Google Code for Klick Conversion Page -->
<script type="text/javascript">
<!--
var google_conversion_id = 1062751462;
var google_conversion_language = "de";
var google_conversion_format = "1";
var google_conversion_color = "ffffff";
var google_conversion_label = "dKXuCODvugEQ5pnh-gM";
var google_conversion_value = 0;
//-->
</script>
<script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
<div style="display:inline;">
<img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/1062751462/?label=dKXuCODvugEQ5pnh-gM&amp;guid=ON&amp;script=0"/>
</div>
</noscript>

With other conversion tracking scripts some function has to be executed to count the conversion. Here, just adding the JS-File to your page can be enough to trigger the conversion-tracking, as conversion.js calls a function on load (download it and look at it after running it through a code beatuifier, it's really quite nice work!).

Any idea how to tackle this?

Don't know if you've already found it... I mention it anyway for future surfers...

I was looking for the same, and found this piece of code :

<script type="text/javascript"> 
    function trackConv(google_conversion_id, google_conversion_label) {
        var image = new Image(1, 1); 
        image.src = "//www.googleadservices.com/pagead/conversion/" + google_conversion_id + "/?label=" + google_conversion_label + "&script=0";  
    }
 </script>

Then for links which you want to track just do this :

<a onclick="trackConv(1234567890, 'LQV8CNq6RxCKlPbvAw');" href="http://www.example.com">Link</a>
