"jqPlot is a plotting and charting plugin for the jQuery Javascript framework." Ooh, nice; another one for the collection.

"Chosen is a JavaScript plugin that makes long, unwieldy select boxes much more user-friendly. It is currently available in both jQuery and Prototype flavors." Nice, elegant.

"pjax loads HTML from your server into the current page without a full reload. It's ajax with real permalinks, page titles, and a working back button that fully degrades." ooh, interesting.

"The jQuery Cycle Plugin is a slideshow plugin that supports many different types of transition effects. It supports pause-on-hover, auto-stop, auto-fit, before/after callbacks, click triggers and much more." It's efficient and well-documented, too. Thumbs up.

This is very good: well explained, the right way around of doing things, and some neat tricks to boot.

"So you want a facebox that shows a form which does an asynchronous submission and updates the facebox with the results of the submission showing error or success messages." Yes, I do. This worked. Thanks, Wes Gibbs.

"Lazy loader is a jQuery plugin written in JavaScript. It delays loading of images in (long) web pages. Images outside of viewport (visible part of web page) wont be loaded before user scrolls to them." Handy.

"Jcrop is the quick and easy way to add image cropping functionality to your web application. It combines the ease-of-use of a typical jQuery plugin with a powerful cross-platform DHTML cropping engine that is faithful to familiar desktop graphics applications." Wow - snappy, well-made, and very impressive.

"slideViewer (a jQuery image slider built on a single unordered list)". Which looks nifty.

"This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript." Nifty.

This was actually a pretty good tutorial for the jQuery UI Slider control, if only for illustrating how much code - notably markup/styles - you have to provide before the slider works.

Very good - some good stuff around how the library works, but also lots of basics around how to optimise Javascript.

A nice approach to doing some of the typical monitoring you'd want to do with Google Analytics, eg monitoring PDF downloads. I'm not totally convinced by some of his syntax, but the functionality is good, and the regex trick is nice.

Getting around the issues with Rails' authenticity tokens and trying to perform Ajax requests in jQuery.

Some really nice code to make decent sliders in jQuery without compromising the underlying HTML.

"I've come up with a plugin that you can inject into a jQuery site that you own and see how the performance breaks down method-by-method." Once again, John is awesome.

"markItUp! is a JavaScript plugin built on the jQuery library. It allows you to turn any textarea into a markup editor. Html, Textile, Wiki Syntax, Markdown, BBcode or even your own Markup system can be easily implemented."

"I thought, why not build a relational database in HTML? So I did. I even got inner joins working." This is insane. Great, but insane.

An up-to-date cheatsheet for jQuery. Nicely laid-out, and nicely dense.

New release of jQuery: as usual, it's a blend of rather impressive performance boosts and some neat new functionality.

"tablesorter is a jQuery plugin for turning a standard HTML table with THEAD and TBODY tags into a sortable table without page refreshes. tablesorter can successfully parse and sort many types of data including linked data in a cell."

"Something to note: as of writing (1.2.2), jQuery doesn’t play nicely with Rails’ respond_to. But, hold the phone, it’s okay: a simple fix." Neat fix. And good to see people working in a similar fashion to me: Rails, jQuery, write the JS by hand.

"Drawing on inspiration from Plotr and PlotKit, software developer Ole Laursen wanted to bring the same plotting functionality to jQuery. So he built his own jQuery plugin and called it Flot." That looks rather nifty.

"In a nutshell, this JavaScript adjusts the line-height of a container (such as a div) in proportion to it’s width, relative to the font size." Nicely implemented typographic jQuery plugin

"I wrote a tiny jQuery extension that logs the current jQuery selection to the firebug console... The nice thing about logging to firebug is that each node becomes clickable in the console, so you can immediately see the context." Excellent!

Awesome jQuery color-picker. Works exactly as it says on the tin. Makes me very happy.

"Most introductions to jQuery focus on designers and inexperienced developers. I’m going to try to explain why jQuery should be of interest to experienced programmers as well." Excellent introduction to jQuery from Simon.

jCodeViewer is a jQuery plugin which allows you to turn any div, textarea or pre tag into a simple Code viewer in an inobtrusive manner.

jQuery plugins, really, but probably worth a look.

When you're manipulating image sizes, you need the image to be fully loaded - so it's worth waiting for the document (rather than just the DOM) to be loaded
