Question

I’d like to track clicks on links that already have javascript onclick event. I’m using analytics but I have no idea how to track these clicks with it.

Answer 1

You can track it with custom message, to distinguish local from others:

 $('.local-link').click(function () {
     _gaq.push(['_trackEvent', 'Local link', 'click', 'some extra message here']);
 });

You can read more about google custom events on google page http://code.google.com/apis/analytics/docs/tracking/eventTrackerGuide.html
