Dummy callback example

var Foo = {
  
  init : function() {
    Foo.getLocation(Foo.showLocation, this);
  },


  showLocation : function(data) {
    console.log("In showLocation callback => " + JSON.stringify(data));
  },


  getLocation : function (callback){
    console.log("fetch guest data from server");
    $j.ajax({
      url: 'http://jsonip.com/',
      type: 'post',
      dataType: 'json',
      success: callback
    });
  },
  
};


Foo.init();
