pubsub.js library

Preparation code

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="https://raw.github.com/Sahadar/pubsub.js/master/pubsub.js"></script>
<script>
  var callback1 = function(event) {
    return false;
  };
  var callback2 = function() {};
  var payload = {
   somekey: 'some value'
  };
  var body;
  var someJqueryObject = $({});
 
  // let's use jQuery.ready to make sure that the DOM is ready,
  // before trying to work with it
  jQuery(function() {
   // we'll use the body element to exchange messages for jQuery
   // if using deeper nested elements, jQuery will be slower, as custom events bubble
   body = $('body');
 
   // subscribe our callback1 function to the custom event for jQuery, only once
   body.bind('my-event', callback1);
 
   // subscribe our callback1 function to the custom event for the plain jQuery object (non-DOM)
   someJqueryObject.bind('my-event', callback1);
 
   // subscribe our callback2 function to the message for PubSub
   pubsub.subscribe('my-event', callback2)
 
   // Use document instead of 'body' as the anchor for custom events
   doc = $(document)
  });
</script>
