Editing PubSubJS vs. jQuery custom events This edit will create a new revision. Your details (optional) Name Email (won’t be displayed; might be used for Gravatar) URL Test case details Title * Published (uncheck if you want to fiddle around before making the page public) Description (in case you feel further explanation is needed)(Markdown syntax is allowed) An attempt at showing that [PubSubJS](http://roderick.dk/blog/2010/10/12/introducing-pubsubjs-a-library-for-doing-publish-subscribe-in-javascript/) is faster than using jQuery custom evens for [publish/subscribe](http://en.wikipedia.org/wiki/Publish/subscribe) style messaging. It's certainly not as rich in features, and I am happy with that. [Introducing PubSubJS](http://roderick.dk/blog/2010/10/12/introducing-pubsubjs-a-library-for-doing-publish-subscribe-in-javascript/) Are you a spammer? (just answer the question) Preparation code Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries) <script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script src="https://raw.github.com/mroderick/PubSubJS/master/src/pubsub.js"></script> <script> var callback1 = function() {}; var callback2 = function() {}; var payload = { somekey: 'some value' }; var body; // 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.on('my-event', callback1); // subscribe our callback2 function to the message for PubSub PubSub.subscribe('my-event', callback2) }); </script> Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script> Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ) Define teardown for all tests (runs after each clocked test loop, outside of the timed code region) (see FAQ) Code snippets to compare Test 1 Title Async (check if this is an asynchronous test) Code body.trigger('my-event', payload); Test 2 Title Async (check if this is an asynchronous test) Code PubSub.publish('my-event', payload); Test 3 Title Async (check if this is an asynchronous test) Code PubSub.publish('my-event', payload, true);
