jQuery Austin Speaker Lineup

Posted on by
jQuery Conference Portland logo

With just over a month until jQuery Austin starts, I wanted to take a few minutes to point out the highlight of our conference program: our talks! With a single-track conference, it’s our job to select individual talks that will appeal to the entire conference audience. At the same time, we want to make sure we cover a broad range of subjects related to jQuery and front-end engineering so that every attendee can take home something that will make a difference in their day-to-day development. Those were our goals with our Call for Papers, and we hope you’ll agree our 20 selections fit the bill.


One of the main focuses of #jqcon is to bring you the latest on what’s going on in the jQuery libraries, and there’s no one better for that than keynote speakers Dave Methvin and Scott González, development leads for jQuery and jQuery UI. Dave will be talking about more than just recent changes to jQuery core; he’ll be delving into how to diagnose what does (and doesn’t) cause performance woes in modern web apps. And with the jQuery UI and jQuery Mobile projects merging, you’ll want to be sure to hear Scott tell what the future has in store.

As increased modularity comes to jQuery, Timmy Willison will describe how and why we’re making the switch to AMD in core, and how to leverage these forthcoming changes in your apps. Julian Aubourg is going to take a dive into Deferreds and Promises, which have been proven to be a useful tool for managing asynchronous code, even since before their incorporation into jQuery a few years ago.


We’re excited to have a number of talks on taming the burgeoning beast that is mobile development. Alex Schmitz will be reviewing the results of the Mobile team’s serious look at the performance of jQuery Mobile for the upcoming 1.4 release, and outline new features that have been added with performance in mind, and Asta Gindulyte will examine how to use jQuery Mobile across a wide variety of screen sizes, from phones right on up to televisions.

Figuring out how to serve the right images to your application’s users across devices and bandwidths has been one of the more interesting discussions in web development for the last year or two, and that’s why we’ve brought Christopher Schmitt to help you make sense of it all. Building applications that work offline is another challenge, and Seth Hallem will explain how to persist, search, update, and display data in HTML5 mobile apps.

Application Development

Debugging is the constant task of software development, and Brian Arnold will be walking us through the constantly-improving tools that can help improve your skills in this dark art. Sometimes, apps appear to work fine until they get into the hands of users who require a screenreader, so Jörn Zaefferer will be giving a primer on the important subject of how to make your web application accessible to all users.

Client-side MVC frameworks are certainly all the rage these days; after having talks on Backbone and Ember at jQuery Portland, we’re thrilled to bring AngularJS into the mix, with Burke Holland bringing you up to speed on directives, one of the framework’s coolest features. If you’ve been using MVC frameworks, one question that you’ve likely wrangled with is where to draw the line between reusable UI widgets and custom application code – which just happens to be one of the subjects Richard Lindsey will be presenting in his discussion of the jQuery UI Widget Factory.

Front-End Ops

Web applications are continuously becoming more JavaScript-centric, bringing increased rigor to the client-side. Grunt has taken off as a popular tool for building and minifying code, and Aaron Stacy‘s talk will explore how to use this JS task runner for even more. Many more developers are recognizing the importance of writing unit tests, and Travis Tidwell will be in Austin to help you incorporate running tests into your deployment process with PhantomJS.

All the technology in the world doesn’t change the fact that web applications are still written by human beings, and Monika Piotrowicz will analyze how we can improve our workflows to better accommodate all the different people who are involved and perhaps even build better products! The jQuery Foundation itself is one organization where we’ve made significant changes to how we work in order to get more developers involved in the project, and Anne-Gaelle Colom will be on hand to detail her experiences as she’s grown to become the Documentation lead for jQuery Mobile.

mind === blown

The open web platform continues to evolve and bring with it exciting new possibilities for what we can do in the browser. Jenn Schiffer will enlighten you on the canvas tag and how it can let you use your coding abilities to be creative and make art, and Vlad Filippov will bring this discussion into a full three dimensions as he shows off voxel.js, a WebGL-based toolkit for creating Minecraft-like worlds and interactive visualizations.

If you’ve got pockets and a phone that vibrates, then you’re surely aware of the utility of push notifications, and Kris Borchers will explain the finer points of their journey to the web platform. Web Components are another emerging spec that have the potential to change how we develop and share reusable widgets, and Juan Pablo Buritica will illuminate the current state of affairs and show tools that will let developers get started writing more modular code today.

Join Us

With so much in store, we hope you’ll head deep in the heart of Texas with us on September 10 and 11! Head on over to the conference site to read more about the program and buy your tickets today. In fact, we’re celebrating the renaissance of our RSS feed with $25 off coupon for anyone who uses the coupon code JQBLOG until we run out of tickets!

If you’re able to attend #jqcon, you’ll probably want to stay within walking distance of the Austin Convention Center in our room blocks at the Hyatt Place and Radisson hotels, especially if you want to be able to explore downtown Austin and rub elbows with your fellow attendees.

If you have any questions, always feel free to get in touch with us on Twitter or via e-mail. If not…see you there!

jQuery Heads to Austin

Posted on by
jQuery Conference Austin logo

This year, we’re happy to be able to resume our tradition of throwing two jQuery Conferences and announce that we’re headed for the first time to Austin, Texas! jQuery Austin is set for Tuesday, September 10 and Wednesday, September 11 at the Austin Convention Center, and we’re planning to host a discussion of the latest developments in jQuery, as well as other tools and techniques from around the world of front end development.

Call for Proposals

We’re looking for speakers who can bring a broad array of perspectives on subjects that cross the spectrum of technologies that are used in tandem with jQuery every day. We love listening to ideas about jQuery, jQuery UI, and jQuery Mobile, but we know there’s a lot more out there. JavaScript, HTML5, CSS, mobile, testing, deployment, and growing as a developer are all subjects jQuery users are eager to hear more about, so if you’ve got something you want to share with the community, we’d love to hear from you.

Our Call for Proposals will be open through July 14th, so we’re hoping to hear from you soon! We’re returning to a single-track format for jQuery Austin, so we’re expecting to have to make some tough decisions once we’ve reviewed the proposals; nevertheless, the only way to be considered is to submit in the first place!

Pre-Conference Training

If you’re looking to understand how to become a better developer and leverage newer features in jQuery, Bocoup‘s jQuery Essentials course on Monday, September 9 is just such an opportunity. The class is taught by Query plugin auteur extraordinaire and Grunt creator Ben Alman, and it’s a great chance to bone up on your skills before the conference begins.

Tickets and Accommodations

Tickets are on sale now, with early-bird pricing available through July 16. You can buy a single ticket for both events, or you can choose to attend only the conference or the training.

We’ve reserved blocks of rooms at the nearby Hyatt Place and Radisson hotels, both of which will leave you just steps from the convention center and downtown Austin.

See You There!

We’re thrilled to be adding some southwestern flavor to #jqcon. The city offers a great backdrop for a few days of learning and connecting with the of the jQuery community while enjoying the BBQ and music. As the saying* goes, “You’ll always remember an Austin September!” Follow @jqcon for news and updates as we have them, we look forward to having you join us in Austin! In the meantime, consider submitting a talk and polishing your cowboy boots!

* This is not actually a saying.

jQuery 1.10.2 and 2.0.3 Released

Posted on by

It’s nearly Independence Day here in the USA, so we’re delivering something fresh off the grill: jQuery 1.10.2 and 2.0.3. These releases fix a few pesky bugs that have been reported over the past month, but the list is refreshingly small. Since some of the bugs spanned both the 1.x and 2.x branches we’re releasing new versions of both to keep them in sync.

You can get the latest files from the jQuery download page, including sourcemap files and links to helpful tools such as jQuery Migrate. If you’re upgrading from a version of jQuery before 1.9, please do read through that page carefully to make your migration as pain-free as possible. Remember that it may take a few days for the CDNs at Google, Microsoft, and CDNJS to respond to the rocket’s red glare and post the latest versions. In the meantime, use the copy on the jQuery CDN.

We’re pretty optimistic that these latest bug-fix releases should be free of surprises. If you drop the new files into your site and see fireworks, please do your patriotic duty and report a bug with a test case (preferably using jsFiddle) at our bug tracker.

These releases wouldn’t have happened without the contributions of Jason Bedard, Jason Merino, Jörn Zaefferer, Michał Gołębiowski, Nguyen Phuc Lam, Oleg Gaidarenko, Richard Gibson, Rick Waldron, Terry Jones, and Timmy Willison.

Live From Portland, It’s jQuery!

Posted on by

Later this week, jQuery Conference is returning stateside for the first time in 2013, and we’re excited to announce another first: inspired by the mighty Willamette River running through Portland, we’re bringing you our first-ever live stream! No matter where you are in the world, you’ll be able to take in both days of #jqcon and the pre-conference Bocoup training. Doing a live stream comes with its own challenges and complexities, so we are selling tickets for each stream, and wanted to take a moment to walk you through your options.

Conference Live Stream

A ticket for the conference live stream costs $149, which entitles you to both tracks on June 13th and 14th. However, jQuery Foundation members get free tickets to the live stream. Membership in the foundation is as little as $100 annually (and you get a t-shirt!), so now’s a great time to join the foundation, show your support for jQuery and learn a whole lot! If a bunch of folks at your company would all like to attend, we’re also selling Group tickets for $749.

Training Live Stream

In addition, live streaming tickets are available for the one-day Bocoup trainings on June 12th for $299, with an additional $50 discount for jQuery Foundation members. You can choose to attend either the Advanced jQuery or Front-end Fundamentals classes. Group tickets are available for $999.

How It Works

Once you buy your live stream tickets, the morning of each event you’ll receive an e-mail with your unique link to the stream. Click on it! (Or simulate a mouse click using the whole document.createEvent song and dance, if you’re so inclined.)

Odds and Ends

We still have a few late-bird tickets remaining, and we’ve just announced we’ll be hosting a party on June 13th thanks to our friends at Jive Software, so if you’re still on the fence, hopefully you just fell off (gently)! Whether you’re joining us in person or on the stream, we’re looking forward to three days of fun and learning, and hope you are too.

As always, follow @jqcon for detailed conference updates, and join us in the #jqcon channel on Freenode to chat with fellow attendees around the room, and around the world.

jQuery 1.10.1 and 2.0.2 released

Posted on by

A new release already? It’s only been a week! Yes, because you deserve it. We’re greatly encouraged by all the people who upgraded and found our well-hidden “we completely hosed relative animations” easter egg. This release restores += animations and friends to their former glory, plus it fixes a few smaller bugs that were reported. Since the bug affected both the 1.x and 2.x branches, we’re doing new releases for both.

As always, you can get the latest files from the jQuery download page, including sourcemap files and links to helpful tools such as jQuery Migrate. Thank you Tom Byrer for pointing out that the sourcemap files weren’t listed on the download page, and also for contacting the CDNJS folks to have them host the sourcemap files.

Many thanks to jQuery team members Corey Frang, Oleg Gaidarenko, and Richard Gibson for quickly jumping on these issues and creating unit tests to prevent future regressions. This ensures we never make the same mistake twice, but instead deliver fresh and unique bugs with each release. If you find any of those, please report them with a test case (preferably using jsFiddle) at our bug tracker.

I hope that we’ll see many of you at the jQuery Conference Portland, coming up just two weeks from now!

jQuery 1.10.1 and 2.0.2 Changelog



jQuery 1.10.0 and 2.0.1 Released

Posted on by

It’s a wonderful day for a software release. Such a wonderful day, we’re doing two software releases! Today it’s jQuery 1.10.0 and jQuery 2.0.1 making their debut — five years to the day after jQuery 1.2.6 was released.

A simultaneous release isn’t always easy, but it can be very satisfying. The team is certainly satisfied with this duo of deliveries; those of you who have already upgraded to the 1.9/2.0 level should have an easy time with these versions. If you’re upgrading older code, the advice in the jQuery 1.9 upgrade guide still applies to these two releases as well. Also don’t forget that jQuery. 2.0 doesn’t support IE 6, 7, or 8 since we’re leaving that work to the 1.x branch. If you need some help updating or keeping older pre-1.9 jQuery code going, don’t forget about the jQuery Migrate plugin.

As always, the latest versions are all available on our download page.

What’s new? Our main goal with these two releases is to synchronize the features and behavior of the 1.x and 2.x lines, as we pledged a year ago when jQuery 2.0 was announced. Going forward, we’ll try to keep the two in sync so that 1.11 and 2.1 are feature-equivalent for example. We don’t anticipate you’ll find any of these to be disruptive changes. Here are a few highlights:

Relaxed HTML parsing: You can once again have leading spaces or newlines before tags in $(htmlString). We still strongly advise that you use $.parseHTML() when parsing HTML obtained from external sources, and may be making further changes to HTML parsing in the future.

Increased modularity: In either version, you now can do a custom build that excludes the .wrap(), .wrapAll(), .wrapInner() and .unwrap() methods. If all your code is using the newer .on() event methods introduced in jQuery 1.7, you can also exclude .bind() and .delegate() as well. The builds available on the jQuery, Google, and Microsoft CDNs continue to include all methods to provide maximum compatibility.

No more IE9 focus of death: If a page inside an iframe attempts to focus an element or even tries to read document.activeElement before the page is ready, it causes an error. We now work around this issue.

Cordova bug fix in 2.0.1: The Cordova deviceready event doesn’t properly set an event target, so we work around the problem by setting the target to document.

Many thanks to the people who contributed work to jQuery 1.10.0 or jQuery 2.0.1: Brandon Johnson, Chris Talkington, Dmitry Gusev, James Burke, Jason Bedard, Julian Aubourg, Kyle Robinson Young, Mark Raddatz, Michał Gołębiowski, Nguyen Phuc Lam, Oleg Gaidarenko, Renato Oliveira dos Santos, Richard Gibson, Rick Waldron, Scott González, Timmy Willison, Timo Tijhof, and Tom H Fuertes.

jQuery Portland Update

Posted on by
jQuery Conference Portland logo

With just over a month remaining until the jQuery Foundation heads to the Pacific Northwest for jQuery Portland, the first U.S. jQuery Conference of 2013, we thought we’d take a moment to bring you up to speed on what we’ve been preparing for when we set up camp on Thursday, June 13 and Friday, June 14 at the Oregon Convention Center.

What’s In Store

We had such a great response to our Call For Papers that picking “only” 31 talks was a real challenge! Our goal was to put together a program that has something for developers with all levels of experience across the entire spectrum of front-end development, and we’re really proud of the results (and our amazing speakers, most of whom are presenting at their first jQuery conference). We’ve put together a Twitter list of all our speakers if you want to connect with them in advance.

If you’re out for the latest and greatest, you’ll probably want to spend a lot of your time in Track A, where we’ll be covering (amongst other things) how and when to use native HTML5 and CSS3 solutions to problems often solved with jQuery, mobile and A/B testing strategies, new technologies like WebRTC and Web Components, as well as future plans for selectors and indeed, JavaScript itself.

Track B, on the other hand, is a great place to shore up your foundations and learn where to take your next steps as a developer. We’ll be covering a whole lot, including JavaScript fundamentals, code organization, unit testing, single page applications (and the frameworks often used to build them), Node.js, and avoiding the kinds of small mistakes that can turn into big problems later.

Of course, you’re free to go to whichever sessions you like in either track, and there’s a lot more on offer, including a few sessions on how to learn and teach yourself and your colleagues, as well as keynotes from project leads on the latest developments in the jQuery ecosystem. Take a look at the full program to see all the talks and read the full abstracts.

Tickets & Accommodations

We’ll be selling regular conference tickets until the end of May, at which point we’ll only be selling “late-bird” tickets, which will cost $50 more, so if you’re planning to join us in Portland, you’ll probably want to act now before the price goes up!

jQuery Foundation members will always be able to buy a ticket for the discounted price of $399, so now’s a great time consider joining the jQuery Foundation to show your support and save a bit as well!

There are still hotel rooms available in our room block at the DoubleTree Portland, but the group rate of $144 per night is only guaranteed for reservations made by May 27th.

If you’re looking to bone up on your jQuery skills before the conference begins, we’ve teamed up with Bocoup to hold beginner and advanced training classes on Wednesday, June 12, for which separate tickets (and similar membership discounts) are available.


We’re happy to have the support of the sponsors who have already joined us to help bring jQuery Portland to life, including Splunk, Intel, AppNexus, Automattic, Infragistics, Act-On Software, and Bocoup.

There are still ways to get involved in making jQuery Portland even better, so take a look at our prospectus and get in touch if you (or your company) are interested.

See You There?

We’re really excited about the way jQuery Portland is shaping up and believe that there’s a little bit of something for everyone. (Everyone who reads the jQuery blog, that is!) Follow @jqcon on Twitter for more updates, and hopefully, we’ll see you in a month!

jQuery 1.10 Beta 1 Released

Posted on by

Today the team is releasing jQuery 1.10 Beta 1. This release should be a relatively easy upgrade for any code that has already been updated for jQuery 1.9/2.0, and it doesn’t introduce a lot of breaking changes–at least not that we know of! That’s why we do beta releases. You tell us.

It may seem like only yesterday that jQuery 1.9 was released, but it was actually all the way back in January. In the meantime, we’ve also delivered jQuery 2.0, the first version of jQuery to leave behind the nightmarish workarounds needed by older versions of Internet Explorer. jQuery 1.10 includes some minor tweaks that we originally introduced in jQuery 2.0, plus bug fixes for issues reported since jQuery 1.9.1.

The biggest change you’re likely to see is that we’ve loosened up the criteria for HTML processing in $(), allowing leading spaces and newlines as we did before version 1.9. We still recommend the use of $.parseHTML() for any HTML coming from external sources. Future versions of jQuery may place tighter restrictions on the kind of markup that $(string) will process, to help you to avoid the ever-present threat of cross-site scripting (XSS) issues.

If you haven’t yet upgraded to the 1.9/2.0 versions yet, catch up by reading the previous blog announcements for jQuery 1.9 and jQuery 2.0. Be sure to check out the jQuery 1.9 Upgrade Guide and the jQuery Migrate plugin.

You can get the beta file here: http://code.jquery.com/jquery-1.10.0-beta1.js

Try this beta code with your most treasured projects and let us know how it works. If you find problems, even when using jQuery Migrate, please report them along with a test case demonstrating the bug at bugs.jquery.com. Please don’t report bugs or ask for help in the blog comments below.

It’s our goal to keep the 1.x and 2.x lines in sync functionally so that 1.10 and 2.0 are equal, followed by 1.11 and 2.1, then 1.12 and 2.2 … well, you see the pattern. Any feature additions or functional changes will happen on these major-point releases. Patch releases will simply fix bugs or bring the two further into sync.

Many thanks to the people who contributed work since 1.9.1 was released: Brandon Johnson, Dmitry Gusev, James Burke, Jason Bedard, Julian Aubourg, Kyle Robinson Young, Mark Raddatz, Michal Golebiowski, Nguyen Phuc Lam, Oleg Gaidarenko, Richard Gibson, Rick Waldron, Scott González, Timmy Willison, Timo Tijhof, and Tom H Fuertes.

jQuery 1.10 Beta 1 Changelog








jQuery Migrate 1.2.1 Released

Posted on by

They say there are no second acts in software … well, there are always second acts in software. Especially when the first act bombs. With that in mind, version 1.2.1 of the jQuery Migrate plugin has arrived. It can be used with either jQuery 1.9 or jQuery 2.0.

This minor update addresses regressions created by the security fix in the 1.2.0 release that rejected some valid HTML strings. Many thanks to GitHub users gerrod, basc, Leonya, krzyko, and lorddefinitia for reporting these issues.

You can find this latest version of the jQuery Migrate plugin on jQuery’s CDN:

Complete instructions and a complete list of the diagnostics given by the plugin are located in the plugin project’s README file.

A full list of all changes are in the issue tracker.

jQuery Migrate 1.2.0 Released

Posted on by

The latest version 1.2 of the jQuery Migrate plugin is here! It can be used with either jQuery 1.9 or jQuery 2.0 to provide diagnostics and remedial help for plugins that haven’t been updated since jQuery 1.9 was released earlier this year. Believe me, this plugin can really make your life easier; if you’ve been afraid of upgrading jQuery, this plugin can cure that irrational software phobia.

The major change in this version is that we’ve re-closed a cross-site-scripting (XSS) hole that was fixed in jQuery 1.7 and reintroduced by the plugin. Essentially, any use of $("#... <tag>") will now always be interpreted as a selector and not as HTML. This is due to some developers using $(window.location.hash) and not realizing that an attacker can often control the contents of the hash on the URL to run code. Always assume that any data you get from an external source may contain harmful content!

You can find this latest version of the jQuery Migrate plugin on jQuery’s CDN:

Using the plugin is as easy as including it right after the version of jQuery you are using, for example:

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.0.js"></script>

Complete instructions and a complete list of the diagnostics given by the plugin are located in the plugin project’s README file.

A full list of all changes are in the issue tracker. Many thanks to Igor Kalashnikov and Max Riviero for their help on this plugin!
