The conference will be held September 12th and 13th at Microsoft Cambridge in Boston, MA.

This will be a 2 day conference with multiple tracks on each day. We’re in the process of planning out the schedule, talking with speakers, and setting up the conference web site.

Watch the jQuery blog or jQuery Twitter feed for notification when registration opens.

While this venue is larger than those that we’ve had in the past (Harvard Law School in ‘07 and the MIT Stata Center in ‘08) we do expect to sell out all the available seats, as has happened every year so far. That being said, the venue is quite incredible, easily one of the best spaces available for a conference:

A brief synopsis of some of the content that you’ll be able to expect:

The annual conference of jQuery users and developers. There will be talks on jQuery, jQuery UI, plugins, complex application development, and more - all from the top jQuery developers. Case studies from some of the leading users of jQuery will be included along with a 3 hour tutorial for those just getting started.

You can see the schedules from past jQuery conferences here: 2008, 2007. There will be a nominal fee (likely around $100-$150) to help us cover to cost of food for both days and shirts.

Looking forward to seeing everyone in Boston this fall!

Note: If you are interested in sponsoring the conference, please contact John Resig.

Update: There have been a lot of questions asking if there will be a conference on the west coast (San Francisco) or in Europe. While we don’t have any immediate plans to hold conferences in those locations, this year, we would like to hold them in the future. In the meantime I recommend checking out Full Frontal (UK, November) and Fronteers (Amsterdam, November) - both of which should shape up to be excellent JavaScript conferences.

Update: Thanks to Jeff for adding the event to Upcoming.

If you have ever used a regular expression tool to highlight character matches in real time, then you’ll jump for joy when I tell you about the Interactive jQuery selector tester written by Samuli Kärkkäinen. You enter a selector expression, and in real time you get to see the elements in the DOM structure that have been selected. I can see this being very handy for complex expressions or for optimizing expressions down to the simplest solution.

Also, in case you didn’t notice, the second maintenance release for jQuery UI 1.7 is out.

jQuery Quote of the Week

“You can save a tremendous amount of time and effort by using the browser-independent framework that JQuery has spent untold man-hours testing, debugging, and proving in the field. While there’s nothing wrong with writing JavaScript, why not speed your development time by writing to the library instead? As I’ve always said, don’t reinvent the wheel, unless you plan on learning more about wheels. ” - Jeff Atwood

jQuery Updates

Brandon Aaron has been writing a series called “jQuery Edge” on his blog, detailing some of the cool enhancements in store for the next version of jQuery. His most recent, New Special Event Hooks, describes the four “hooks” that make up the new custom event API: setup, teardown, add, and remove. It’s a must-read for anyone working with event-driven jQuery scripts.

Plugins

Ben Alman describes his jQuery iff plugin: a chainable “if” statement.

Pete Higgins of Dojo fame has written a jQuery pub/sub plugin, “loosely based on the Dojo publish/subscribe API.” His plugin joins other publish/subscribe plugins such as Fling and jQuery Subscribe/Publish.

Paul Irish has ported a YUI3 script to jQuery for his idleTimer plugin. The plugin detects when a user has become idle.

Jonathan Sharp released an XMLDom plugin, which “takes a string of XML and converts it into an XML DOM object for use with jQuery.”

jQuery + Server-Side Solutions

A common complaint in the earlier days of jQuery was that there wasn’t enough information on how to integrate jQuery with server-side languages (or frameworks), so it’s nice to see a proliferation of tutorials in this area. Here are a few of the recent ones:

• ColdFusion: Validating Common Email Domain Misspellings using ColdFusion and jQuery. Incorporates the Autocomplete plugin.
• ASP.NET: Walkthrough: full example of using MvcContrib grid with jQuery datatable
• Ruby on Rails: Add jQuery datagrids to your Rails applications
• PHP: PHP Contact Form with JQuery Validation

Plugins

• Eric Garside’s jStore plugin “allows users to access a number of different client-side storage engines through a single, convenient interface.”
• Inspired by James Padolsey’s article Introducing: JSHTML, Ben Nadel put together a jQuery Comments() Plug-in To Access HTML Comments For DOM Templating.
• Horizontal Accordion: Just released 2.0 Alpha version.
• jqPlot now joins the popular Flot plugin as a fully client-side charting solution.
• jCart: a free jQuery/PHP-based shopping cart.

Fun Stuff

Chris Barr used jQuery to create a fun little game, Guessr: Guess the Flickr Tag, which also takes advantage of the jQuery UI ThemeRoller.

Featured jQuery App

The folks at Carsonified have just released a beta of Twiggy, an app that searches Twitter from Nokia’s widget-enabled phones Opera as a widget. Widget apps are built in HTML, CSS and Javascript, and are stored and executed locally. Twiggy lets you search Twitter and save favorites.
Elliott Kember, who along with Mike Kus is responsible for creating Twiggy, describes their use of jQuery in the app:

Twiggy uses jQuery for all the Javascript animations and layout changes. There are a few small widget-only APIs that interface with the phone, but I’ve used jQuery for the user interaction bits. I didn’t end up using anything very complex or tricky due to the limited time frame, but I found that the phone handled animations really well. It’d be very interesting to design a much bigger app and take the phone to its limits.

I used a Twitter jQuery plugin from http://tweet.seaofclouds.com/ and it worked just fine. I didn’t use jQuery UI - but I’d be interested to see whether it worked on such a limited platform.

I chose to use jQuery because it’s familiar, reliable and fast. I didn’t want to use custom little libraries and functions which might not work so well. I was really pleased to find that the N96, for one, runs jQuery really well in this runtime. I half-expected the rendering engine to be slow, or buggy, and shoe-horned into the phone somehow, but it’s quite happily running a full, packed jQuery 1.3.2.

Upcoming Conference

jQuery Project Team members Yehuda Katz and Brandon Aaron will be presenting jQuery on Rails on May 4 at RailsConf 2009 in Las Vegas.

Free Book Chapter

Packt Publishing has posted a sample chapter of the new Learning jQuery 1.3 book. You can download the free PDF.

Don’t forget to check out This Week in jQuery UI

Book

Jonathan Chaffer and I (Karl Swedberg) just had our book Learning jQuery 1.3 published by Packt Publishing. It’s an update of the popular Learning jQuery book, which was released nearly two years ago. The new one features additions to the library (event namespacing, JSONP, new effects methods, etc.) introduced since the release of the first book, improved and extended examples, expanded plugins chapters, and a quick reference to all methods and selectors. It’s available on the Packt website and on amazon.com.

Magazine

JSMag, a promising new magazine for JavaScript developers, just published their first issue. The magazine’s goal is to provide “quality JavaScript content to educate, motivate and inspire you in your work with JavaScript.” PDF-only issues are US$4.99 each, with bulk licensing discounts starting at 30% off the individual price. Contents of the first issue include:

• Debugging JavaScript without alert()
• Introduction to ExtJS
• Community News
• Unit testing with YUI
• What’s new in jQuery 1.3
• Functional Programming in JavaScript

Check out a sample (PDF) from the first issue.

Plugins

Among the ever-growing selection of jQuery plugins, a few perennial favorites were updated this week. Ariel Flesler released version 1.2.7 of his LocalScroll plugin, which animates anchor navigation within a web page. Mika Tuupola updated his Jeditable plugin, for seamless in-place editing, with a number of “callback hooks” and a few bug fixes. Josh Bush’s new version of Masked Input includes bug fixes and a few feature enhancements as well.

After looking for a simple, fast and flexible grid/spreadsheet component, Michael Liebman decided to roll his own. This week he put out a call for contributors, seeking “experienced developers who can pick this up and turn it into something that everybody can use,” perhaps by converting it into a plugin. The code can be found at http://code.google.com/p/slickgrid/.

Tutorials

Steve Reynolds has posted a tutorial on how to create OS X Dashboard Widgets with jQuery. For those who want to know “What in the heck is JSONP and why would you use it?” Raymond Camden gives you the answers on the O’Reilly Inside RIA blog (hint: cross-domain ajax).

Quick Tip

We often see questions posted in the jQuery Google Group about why a jQuery script is “broken” in Internet Explorer when it works in all other tested browsers. By far the most common solution in these cases is to search for and then remove a trailing comma from the last key-value pair in an object literal:

var foo = {
  bar: 'ice cream',
  baz: 'luhrmann', // <-- get rid of that comma!
}

This can especially trip up developers who are used to other languages such as PHP, in which including the trailing comma is considered a “best practice.” JSLint is a great tool to run your JavaScript through periodically, as it does a great job of flagging these kinds of errors and warnings for you. If you use TextMate, the JavaScript Tools bundle runs a “quick JSLint” every time you save your JavaScript file and runs the full JSLint, along with a number of other conveniences, from the bundle’s menu.

Well, that’s it for this week. Be sure to check out This Week in jQuery UI, too!

Full details of this new & exciting release can be found on the new jQuery UI blog.
