Problem:

I was working on an international website for Le Pain Quotidien.
Depending on which country is chosen on the homepage, an other Google Analytics Tracker had to be used.

Solution:

I wrote a class which allows to create trackers at Runtime, and send tracking information to a specific tracker.

How it works:

The system consists of 2 classes:
- An AnalyticsManager class, which allows to add or remove trackers at runtime.
- An AnalyticsTracker class, which uses ExternalInterface to send the tracking-information to it’s associated tracker.

Code in AS3:

var analytics:AnalyticsManager = new AnalyticsManager ();
analytics.addTracker ("pageTracker1");
analytics.addTracker ("pageTracker2");

analytics.getTracker ("pageTracker1").track ( "tag_for_tracker_1" );
analytics.getTracker ("pageTracker2").track ( "tag_for_tracker_2" );

Code in HTML:

<script type="text/javascript">
   var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
   document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
   var pageTracker1 = _gat._getTracker("UA-xxxxxxx-1");
   var pageTracker2 = _gat._getTracker("UA-xxxxxxx-2");

   pageTracker1 ._trackPageview("/home");
</script>

Files:

You can download the files here:
AnalyticsManager.zip

The class uses a HashMap to save the trackers.
The HashMap classes are included in the zip-file.
