jQuery-based outbound link tracking with cases for new window as well as same window locations

Hi,

onmousedown worked great for me

<a href="#" onmousedown="_gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']);">My Link</a>

Better the than the Google code: Outbound links https://support.google.com/analytics/answer/1136920?hl=en.

There is a bit of a setback in the last script. If the address is using relative domain it will be counted as externel. We can do a simpe check:

jQuery(function($){
  $('a:not([href*="' + document.domain + '"])').mousedown(function(event){
    // Just in case, be safe and don't do anything
    if (typeof _gat == 'undefined') {
      return;
    }

    var link = $(this);
    var href = link.attr('href');
    if (href.charAt(0) != '.' && href.charAt(0) != '#' && href.charAt(0) != '/) {
       var noProtocol = href.replace(/http[s]?:\/\//, '');

       // Track the event
       _gat._getTrackerByName()._trackEvent('Outbound Links', noProtocol);
    }
   });
});

This will check if the first char is a part of a relative domain name.

mousedown doesn't mean they clicked the link. You could get false data if they click on the element and drag away (not finishing the mouseup on the element).
