jQuery source viewer. A neat way of browsing the source code of jQuery itself, complete with hyperlinks to other jQuery methods. Kind of a single-purpose IDE. I can see myself using this a lot.

HTML 5 audio player demo. Scott Andrew’s experiments with the HTML5 audio element (and jQuery)—straight forward and works a treat in Safari, but Firefox doesn’t support MP3. Presumably it’s not too hard to set up a fallback for Ogg. 1st February 2010, 9:58 am
Dojo 1.4.1 vs jQuery 1.4.2pre on Taskspeed. John Resig’s reponse. When JavaScript libraries compete on performance, everybody wins. 29th January 2010, 2:19 pm
Dojo: Still Twice As Fast When It Matters Most. Alex Russell shows how Dojo out-performs jQuery on the TaskSpeed benchmark, which attempts to represent common tasks in real-world applications and has had code that have been optimised by the development teams behind each of the libraries.

jQuery 1.4 Released. With comprehensive release notes. Huge performance improvements and a ton of very sensible enhancements to the API—far too many to summarise. 14th January 2010, 10:37 pm
qTip. Advanced tooltip plugin for jQuery, including borders and pointers created using CSS. Very flexible (we used this for the latest MP expenses application) but a little on the heavy side, weighing in at 38KB when minified. 
30th December 2009, 6:23 pm
tipsy. Simple Facebook-style tooltip plugin for jQuery. 30th December 2009, 6:21 pm
jQuery.require() implementation. John Resig has added a new jQuery.require() function to a jQuery development branch, for release as part of jQuery 1.4. The commit on GitHub has an extensive discussion attached to it (scroll to the bottom). 17th December 2009, 11:24 am
jQuery 1.4 Alpha 1 Released. Impressively the new version contains no new features at all (correct me if I’m wrong), instead focusing on significant performance improvements to the existing API. 5th December 2009, 5:31 pm
jQSlickWrap. Clever jQuery plugin which allows text to wrap around irregularly shaped images, by processing the image with canvas and rewriting it as a sequence of floated horizontal bars of different widths. It’s a a modern variant of the the ragged float trick first introduced by Eric Meyer. 23rd November 2009, 7:44 am
Underscore.js. A new library of functional programming primitives for JavaScript—each, map, all, any, inject, detect etc. Unlike some similar libraries this one doesn’t extend the built-in objects, instead opting to bind the new functions to the underscore symbol. A jQuery-style noConflict() option is available if even that is too much namespace pollution for you. 28th October 2009, 5:08 pm
BBC: Glow (via) The BBC have released Glow, their jQuery-like JavaScript library developed in house over the past few years. It’s open source under the Apache license. 8th July 2009, 3:25 pm
SWFUpload jQuery Plugin. Nice looking plugin around an invisible Flash shim that provides multiple file uploads and client-side progress indicators. 
16th June 2009, 11:46 am
Dojo 1.3 now available. Looks like an excellent release. dojo.create is particularly nice—I’d be interested to know why something similar has never shipped with jQuery (presumably there’s a reason) as it feels a lot more elegant than gluing together an HTML-style string. Also interesting: you can swap between Dojo’s Acme selector engine and John Resig’s sizzle.

Special Events in jQuery. How to add a custom “tripleclick” event to jQuery, using the jQuery.event.special extension hook. 30th March 2009, 10:15 am
A few notes on the Guardian Open Platform
This morning we launched the Guardian Open Platform at a well attended event in our new offices in Kings Place. This is one of the main projects I’ve been helping out with since joining the Guardian last year, and it’s fantastic to finally have it out in the open. [... 839 words]

Combine JSONP and jQuery to quickly build powerful mashups. jQuery’s JSONP support is one of my favourite little-known features of the library. 3rd March 2009, 3:17 pm
jQuery Sparklines. Delightful Sparklines implementation, using canvas or VML in IE. A neat nod towards unobtrusiveness as well: you can specify your data as comma separated values inside a span, then use a single jQuery method call to convert the span in to a sparkline image. 27th February 2009, 8:43 pm
Oscars 2009: the interactive results | guardian.co.uk. My latest project for the Guardian, put together on very short notice. Updates live as the results are announced, and allows Twitter users to vote on their favourite for each category by sending a specially formatted message to @guardianfilm—jQuery and Ajax polling against S3 under the hood. 23rd February 2009, 2:19 am
I think you overstate the usefulness of the [jQuery Rules] plugin. Using this plugin, users are now limited by what selectors that can use (they can only use what the browsers provide—and are at the mercy of the cross-browser bugs that are there) which is a huge problem. Not to mention that it encourages the un-separation of markup/css/js.
— John Resig 22nd February 2009, 11:11 pm
jQuery.Rule (via) jQuery plugin for manipulating stylesheet rules. For me, this is the single most important piece of functionality currently missing from the core jQuery API. The ability to add new CSS rules makes an excellent complement to the .live() method added in jQuery 1.3. 
22nd February 2009, 5:53 pm
jQuery 1.3.2 release notes. Not just a bug fix—there are a number of subtle behaviour changes, including to the :visible/:hidden selectors and the appendTo/prependTo/*To family of methods. I strongly recommend testing and reviewing those changes before upgrading. 21st February 2009, 4:42 pm
jQuery 1.3.1 Released. Bug fix for 1.3, mainly browser compatibility issues. Of interest: jQuery no longer ship a packed version (where JS is used to further decompress a string), as their tests show that this reduces performance due to the overhead of the extra decompression. They still provide a YUI Compressor minified version. 22nd January 2009, 10:41 am
jQuery queue method. New in jQuery 1.3, but quite far down the release notes. This finally allows low-level control over the jQuery animation queue without needing an extra plugin. 14th January 2009, 6:09 pm
jQuery 1.3 release notes. Sizzle (new selector engine, available separately), Live Events (a variant of event delegation), Feature Detection (instead of user agent sniffing), faster HTML injection and more. 14th January 2009, 6 pm
jQuery 1.3 and the jQuery Foundation. The IP for jQuery and jQuery UI now rests with the Software Freedom Conservancy (a smart alternative to setting up a brand new foundation), while Sizzle is a separate project looked after by the Dojo Foundation. 14th January 2009, 5:59 pm
jQuery: Changeset 5990. “Added a new liveQuery/event delegation hybrid method”. Lets you add events that continue to work as new elements are dynamically appended to the DOM, e.g. $(’div p.foo’).live(’click’, fn). Works by adding an event handler to the root document element itself and relying on event bubbling. I have to admit I preferred the earlier proposal of $(’div’).delegate(’p.foo’..), which feels like it should have much better performance—anyone know of a good plugin that supports this? 
23rd December 2008, 12:22 pm
jQuery changeset 5985 (via) jQuery trunk has ditched browser sniffing in favour of feature testing, where a small suite of unit-test-like code blocks is used to detect whether a browser supports specific idioms. If the tests fail jQuery still makes assumptions about what the fix is, but it’s not hard to imagine the library eventually using code tests to ensure the fix will work as well. 22nd December 2008, 10:58 am
husk.org. a flickr machine tag browser (via) Flickr recently added API methods for exploring the machine tags used by the community. Paul Mison has built a neat OS X Finder style interface for exploring them, using JSONP and jQuery. 15th December 2008, 11:24 pm
Extending jQuery’s selector capabilities. I already knew this was possible, but the examples James Padolsey provides are eye-opening—I especially like his clever :data selector extension which lets you write CSS selectors that query against jQuery’s custom “data” DOM element storage in a manner similar to CSS2 attribute selectors. 12th December 2008, 6:05 pm
Visual Event. External code loading bookmarklet that visualises the JavaScript events hooked up to the current page, and lets you view the source code of the event handling function for each one. Only works for events added by jQuery, YUI or MooTools since those libraries maintain a cache of event handlers that they add, to work around the standard DOM’s omission of handler introspection. 10th December 2008, 3:38 pm
pyquery. “A jQuery-like library for Python”—implemented on top of lxml, providing jQuery style methods for manipulating an HTML or XML document. 6th December 2008, 9:53 am
jQuery history plugin. I used this plugin to add back button support to a small Ajax app today, with great results. I tried it a while ago and it didn’t work in Safari, but someone has updated it since and now it works perfectly. 7th November 2008, 5:32 pm
freebase-suggest (via) A jQuery plugin that performs auto-completion against the Freebase JSONP API, and allows the results to be limited to specific categories or subsets. 24th September 2008, 11:58 pm
Django snippets: Orderable inlines using drag and drop with jQuery UI. Code example from my PyCon tutorial on customising the Django admin interface. 13th September 2008, 12:19 pm
jeresig’s sizzle. Sizzle is a new selector engine (work in progress, no IE support yet) from John Resig, designed to be small, standalone, library agnostic and ridiculously fast. It should eventually replace jQuery’s current selector engine, but if it stays around 4KB it’s also going to be really useful for projects that don’t need the overhead of a full library. 24th August 2008, 11:41 pm
Making queries faster isn’t in the critical path for improving the real-world performance of any Dojo apps I know of, and I bet the same is true for JQuery users. Reducing the size of the libraries, on the other hand, is still important. Now that we’re all fast enough, it’s time that we stopped beating on this particular drum lest we lose the plot and the JavaScript community continue to subject itself to endless rounds of benchmarketing.

querySelectorAll in Firefox 3.1. John Resig benchmarks the various JavaScript libraries’ support for querySelelectorAll, and finds an impressive 2-6x performance improvement over native DOM traversal. It’s worth clicking through to John’s experimental plugin for adding support to jQuery, which does a clever trick using __proto__ to convert the collection returned by querySelectorAll in to a jQuery object in browsers that support it. 21st August 2008, 9:50 am
Table Drag and Drop jQuery plugin. Drag and drop of table rows is a special case (jQuery UI doesn’t seem to support it)—this plugin works pretty well though. 4th July 2008, 12:04 pm
When Bugs Collide: Fixing Text Dimming in Firefox 2. Handy tips from Drew on fixing the glitchy text rendering in Firefox 2 when you animate opacity without breaking alpha-transparent PNGs in IE6. 19th June 2008, 6:09 pm
Deep Profiling jQuery Apps. Neat plugin from John Resig that monkey-patches most (all?) of the jQuery methods to build up a detailed profile of which methods are being used by a given page. 16th June 2008, 10:20 am
Updated jQuery Bookmarklet. Nicer than my own “Inject jQuery” bookmarklet because it drops in a temporary message confirming that jQuery has been imported (or telling you that jQuery was already present). 8th June 2008, 8:46 pm
Google AJAX Libraries API (via) Google are hosting copies of jQuery, Prototype, mooTools and Dojo on their CDN, with a promise to permanently host different versions and an optional JavaScript API to dynamically load the most recent version of a library. I wish they’d stop capitalising Ajax though. 
27th May 2008, 5:56 pm
QUnit. The jQuery unit testing framework is now documented and supported as a separate project. 26th May 2008, 5:31 pm
Cubescape. Beautiful isometric cube building tool by Cameron Adams, written in JavaScript and jQuery. 15th May 2008, 8:40 am
Doctype: /trunk/goog. Google’s newly released JavaScript library (pure JavaScript, so more along the lines of YUI and jQuery than GWT). I haven’t found the documentation for it yet, but the code is extremely well commented. UPDATE: The documentation is spread throughout Doctype. 14th May 2008, 9:12 pm
Unobtrusive JavaScript with jQuery. The online handout for the tutorial I gave this morning at XTech. 
6th May 2008, 6:53 pm
jQuery style chaining with the Django ORM
Django’s ORM is, in my opinion, the unsung gem of the framework. For the subset of SQL that’s used in most web applications it’s very hard to beat. It’s a beautiful piece of API design, and I tip my hat to the people who designed and built it. [... 820 words]
Classy Query. Beautifully implemented parody of class-based JavaScript and verbose namespacing as a jQuery extension, from John Resig. The source code has some neat tricks in it, in particular the buildClass() function. 1st April 2008, 9:48 am
“Why doesn’t jQuery have an XPath CSS Selector implementation?” For now, my answer is: I don’t want two selector implementations—it makes the code base significantly harder to maintain, increases the number of possible cross-browser bugs, and drastically increases the filesize of the resulting download.
— John Resig 11th February 2008, 5:31 am
jQuery 1.2 Cheat Sheet. Handy. It helps that most of jQuery’s method names are pretty much self explanatory once you’ve been using the library for a couple of weeks. 10th February 2008, 9:12 pm
Event Delegation Made Easy. Dan Webb demonstrates a neat trick for event delegation in jQuery, using CSS selectors and the jQuery .is() method to dispatch to different callbacks from a single event handler based on the target of the event. 10th February 2008, 3:13 pm
Low Pro For jQuery? Dan Webb on why he prefers Prototype over jQuery: “The one big reason was that, while jQuery was super simple and concise when working on smaller projects, it offered no help in structuring larger applications”. 3rd February 2008, 10:16 pm
jQuery.ScrollTo (via) Neat jQuery plugin for animated scrolling of both windows and overflow elements. 21st January 2008, 9:53 pm
.first() and .last() methods for jQuery. I got fed up of expecting these to exist, so I wrote them as a couple of one-liner plugins. 16th January 2008, 9:41 pm
jQuery 1.2.2: 2nd Birthday Present. The API stays the same, but there are some healthy speed improvements, a new way of adding custom events and (most importantly) .ready() now waits for the CSS to be ready in addition to the DOM. 15th January 2008, 8:59 am
$.comet (via) The first Comet (with Bayeux) plugin I’ve seen for jQuery—currently only handles long-polling over XMLHttpRequest, but still a promising start. 9th January 2008, 8:31 am
Two-Faced Django. Excellent Django tutorial by Will Larson that shows how to build a polling application with an interface both on the Web and in Facebook. Also touches on unit testing and Ajax using jQuery. 14th December 2007, 2:44 pm
Unobtrusively Mapping Microformats with jQuery. My contribution to 24 ways: using Mapstraction to geocode hCards (extracted with jQuery) and plot them on a Google Map. 12th December 2007, 12:28 am
dojo.NodeList API docs. Support in Dojo for jQuery-style chaining operations. 8th November 2007, 11:16 am
Upgrading to Prototype 1.6: real world examples. I still don’t find Prototype as intuitive as jQuery, but the API improvements between 1.5 and 1.6 are very impressive. 24th October 2007, 7:19 pm
jQuery Logging (via) Brilliant four line jQuery plugin that lets you insert Firebug console.log() calls directly in to chains. 19th October 2007, 12:52 pm
Using the jQuery test suite for your own projects. jQuery’s test suite has clever start(), stop() and expect() methods for running assertions within asynchronous code. 12th October 2007, 12:56 pm
Roll out your own JavaScript Interfaces. Dustin shows how to build a tiny jQuery-style (chainable) library that contains your own JavaScript convenience functions. 6th October 2007, 12:20 am
I have another technique [...] that I’ll be switching jQuery to. If you attempt to insert into the document.body before the document is fully loaded, an exception is thrown. I take advantage of that to determine when the document is fully loaded.
— John Resig 26th September 2007, 12:21 pm
jQuery 1.2. Lots of neat new stuff; my favourite new feature is “Partial .load()” which lets you pull in HTML with Ajax and then use a CSS selector to grab a subset of that page and inject it in to the DOM. 11th September 2007, 8:44 am
Protoscript (via) JavaScript tool designed for easy prototyping of JS interactions; powered by YUI and jQuery. 7th September 2007, 10:55 pm
jQuery 1.1.4: Faster, More Tests, Ready for 1.2. The backwards compatibility policy for 1.2 is pretty clever: provide a plugin that restores removed functionality (such as XPath selectors). 24th August 2007, 4:22 pm
Building a JavaScript Library. Slides from John Resig’s Google Tech Talk. Some great tips in here, including: make your APIs orthogonal, look for common patterns, keep things extensible and write the documentation yourself. 24th August 2007, 4:02 pm
Live Query jQuery plugin. Ingenious plugin that lets you register jQuery event bindings to be executed when a new element matching the provided selector is added to the DOM. Performance is kept snappy by only running the check after a jQuery DOM manipulation method has been executed (append, prepend, attr etc); it won’t notice elements added using regular DOM methods. 22nd August 2007, 10:01 pm
Learning jQuery. An entire year’s worth of jQuery tutorials, split in to beginner, intermediate and advanced. 17th August 2007, 11:50 am
jQuery for JavaScript programmers
When jQuery came out back in January 2006, my first impression was that it was a cute hack. Basing everything around CSS selectors was a neat idea (see getElementsBySelector) but the chaining stuff looked like a bit of a gimmick and the library as a whole didn’t look like it would cover all of the bases. I wrote jQuery off as a passing fad. [... 2608 words]
Background Iframe (bgiframe). jQuery plugin that inserts an iframe shim behind an element in IE, allowing the element to be positioned overlapping a select box without the select box showing through. 9th August 2007, 2:54 pm
jQuery in 15 minutes. A quick introduction I put together. Much more interesting in conjunction with Firebug powered demos. 7th August 2007, 2:57 pm
jQuery Taconite Plugin. Lets you serialize jQuery DOM manipulation commands as an XML document for retrieval via Ajax. 2nd July 2007, 6:29 pm
jQuery plugin: Validation. Pretty clever way of attacking the client-side form validation problem; supports both configuration object literals and custom attributes on the form fields themselves. 30th June 2007, 10:26 pm
The website to web application gradient. Jeremy snapped this cunning illustration at my JavaScript Libraries panel at the Web 2.0 Expo. 20th April 2007, 12:30 am
Ext JS. Jack Slocum is building a business around his excellent Ext JavaScript library (which can now run on top of YUI, jQuery or Prototype). The library itself is LGPL, but you can pay for a commercial license and support. 3rd April 2007, 10:11 pm
DED|Chain JavaScript Library (via) Dustin’s new JavaScript library, which puts a JQuery style chained API on top of YUI. 20th March 2007, 10:36 am
Microformats Bookmarklet. Microformats bookmarklet, targetted at Safari. Uses jQuery CSS selectors for parsing, and generates .vcf vCard files using data: uris. 27th February 2007, 11:43 pm
John Resig: Thoughts on OpenAjax. I hadn’t looked in to OpenAjax—from John’s analysis it seems like they need to make it easier for open-source projects to participate and do a bunch of work to modernise their core library. 22nd February 2007, 10:20 pm
jQuery 1.1. jQuery is one year old. The latest release features API improvements and some significant optimisations. 15th January 2007, 5:13 pm
