omniture Utilities:

• events: provides the track_event method for sending a simple or complex data payload in response to an event.
  
  
• storage: methods for storing omiture-related data in localStorage
  
  
• utilities: data transformation and eVar/prop setup tools
  
  
• userdata: specific user  data handling for CMG metrics; also, it is the browserify entry point

• track_event takes a variable number of arguments
• Examples
  

  var track_event = cmg.s_coxnews.utilities.track_event;
  // The simple scenario
  $('.myLink').click(function () {
      track_event(42, this,
          ['eVar61', 'prop61', 'a bit of data'],
          'Clicked my link'
      );
  });
  

  // A more complex situation
  $('.myLink').click(function () {
      var args = [42, this];
      args.push(['eVar61', 'prop61', 'a bit of data']);
      if ($(this).parent().is('.feature')) {
          args.push(['eVar63', 'prop72', 'featured']);
      }
      args.push('Clicked my link');
      track_event.apply(null, args);
  });
  

• Used primarily to cache data from Janrain currently
  
  
• Automatically namespaces keys to cmg_sc to indicate they are for SiteCatalyst data and JSON [de]serializes them for you
  
  
• Could be used to cache data from any third-party provider or from Medley data
  
  
• store and restore methods
  

• store('userdata', {…my user data …});
  
  var userdata = restore('userdata');
  // OR
  restore('userdata', function (data) { …do stuff with userdata… });

• Provides tools for complex data transformation and eVar/prop setup
  
• transformer: generates configurable transform functions 

var transform_config = [
    ['user.gender', 'gender'],
    ['user.birthday', 'age', function (birthday) {
        var ts = Date.parse(birthday + 'T00:00:00'),
            now = Date.now();
        return Math.floor((now - ts) / (365.25*86400000));
    }],
    ['user.primaryAddress.zip', 'zip']
];
var userdata_transform = transformer(transform_config);

var transformed = userdata_transform({
    user: {
        gender: 'm',
        birthday: '1974-07-03',
        primaryAddress: { street: '123 Main St.', zip: 30303 }
    }
});
// returns { gender: 'm', age: 39, zip: 30303 }

// returns a function that given a data object
// (typically a transformed one), will iterate the var_config,
// perform any additional transforms, mappings or data gathering
// and return an object containing eVar/prop values
// to be (programmatically) set on cmg.s_coxnews via ($||_).extend.
// eVar7 and prop7 will be set per the data function in var_config's
// first entry, and so on, when userdata_setup is called

// returns "eVar7,prop7,eVar3,prop3,eVar4,prop4,eVar5,prop5"
var userdataTrackVars = track_vars(var_config);
