Simple tracker code for GA

track.jquery.js

$.fn.track = function(event) {
  event = typeof event !== 'undefined' ? event : 'click';
  if(!window.console){ window.console = {log: function(){} }; }
  $(this).on(event, function(e) {
    var category = $(this).data('category');
    var action = $(this).data('action');
    var label = $(this).data('label');
    try {
      if (category && action && label) {
        console.log('ga track event: ', category, action, label);
        ga('send', 'event', category, action, label);
      } else if (category && action) {
        console.log('ga track event: ', category, action);
        ga('send', 'event', category, action);
      }
    }
    catch(e) {
      console.log(e.name, e.message);
    }
  })
};
