jQuery 1.7 Beta 1 Released

Posted on by

If you hadn’t heard, jQuery Conference 2011 is taking place in Boston later this week. We’ve put together a little something we like to call jQuery 1.7 Beta 1 that we’ll be talking a lot more about at the conference. It’s got a lovely bunch of new features and significant bug fixes–more than 50 of them at last count.

You can get the beta from the jQuery CDN:

Please help us by dropping this code into your existing application and letting us know if anything no longer works. Please file a bug ticket and be sure to mention that you’re testing against jQuery 1.7 BETA 1.

Also be sure to explore all the new features and see if your favorite pet-peeve bug has been fixed. If you wait until the final release to do your testing it will be too late!

As always, we want to encourage everyone from the community to try and get involved in contributing back to jQuery core. We’ve set up a full page of information dedicated towards becoming more involved with the team. The team is here and ready to help you help us!

Oh, you probably want to know what changed, right? Addy Osmani has made a great start with his recent post, so let’s cover the stuff that isn’t on his list.

New Event APIs: .on() and .off()

Over time, jQuery has evolved three ways to attach events to elements: .bind() , .live(), and .delegate(). Underneath it all, though, the three event APIs call the browser’s event system; that can lead to surprising interactions. For example, $(document).unbind("click") will remove all .live("click", ...) events, since those delegated events are attached to document. (This is also why you should use event namespaces.)

Our current event APIs aren’t going away soon, but to address the inconsistencies we’ve introduced a new and simple pair of event methods that can do the work of all three:

    $(elems).on(events, selector, data, fn);
    $(elems).off(events, selector, fn);

If a selector is provided, it’s a delegated event; otherwise it’s directly bound. All the features of the old APIs are there; for example events can be a space-separated string of event names and/or namespaces, or it can be an object where the keys are events and the values are event handler functions. Here are some examples of how the old methods map into the new ones:

Old API New API
$(elems).bind(events, fn) $(elems).on(events, fn)
$(elems).bind(events, { mydata: 42 }, fn) $(elems).on(events, { mydata: 42 }, fn)
$(elems).unbind(events, fn) $(elems).off(events, fn)
$(elems).delegate(selector, events, fn) $(elems).on(events, selector, fn)
$(elems).undelegate(selector, events, fn) $(elems).off(events, selector, fn)
$(selector).live(events, fn) $(document).on(events, selector, fn)
$(selector).die(events, fn) $(document).off(events, selector, fn)

Form Change and Submit Events in IE 6/7/8

These old Internet Explorer versions are likely to be haunting us for some time, so we’ve spent a while trying to improve their behavior. Event delivery performance has been greatly improved for them, but the biggest change is that we are using a different approach to fix their non-bubbling and broken form events. As a result we were able to greatly simplify and shorten the special events code. These events should work without any problems–even better than before, since we closed about a half-dozen related bugs–but please keep your eyes open for any unusual behavior.

Animation Improvements

Before version 1.7, if you stopped an animation before it completed it could create a situation where the element being animated would never return to its full size; it would essentially be stuck at the height that it was when the animation was stopped. We’ve fixed that by remembering the original dimensions before the animation starts so that they can be used later. This eliminates a major annoyance in using certain animations, particularly toggling ones.

.removeData() Enhancements

Addy mentioned this one as well, but the .removeData() API now lets you pass either a space-separated string of names or an array of names to be removed. Since spaces were previously allowed in data names, the code first checks for the exact name as you specified it before splitting the string on spaces. That way, no existing code should break as a result of this enhancement.

Just Added: HTML5 Training at jQuery Conference Boston!

Posted on by

Update: For the first time ever, we have a conference signage sponsor. Thanks to custom signs shop Signazon for your support.


The Boston conference is sold out (thanks everyone!), as is the Intro to jQuery training session, but the requests keep coming! In response to popular demand, we’ve added a second training scheduled for Friday, September 30th.

The training will focus on HTML5, and be taught by jQuery Core Team Member and Bocoup trainer Richard Worth. The price will be the same $299 (which, if you’ve been paying attention to HTML5 training rates, is a steal!).

Here’s some detail from the training description:

HTML5 is the next major milestone in HTML and it’s not just another incremental enhancement; it represents an enormous advance for modern web applications. A large number of HTML5 features are already supported in browsers, so it’s time to start using them!

In our HTML5 for Programmers Workshop, you will learn how to create HTML5 web pages and web applications using semantic HTML5 markup and cross-browser HTML5 JavaScript APIs. After completing this course, students will:

  • Know how to use semantic HTML5 Markup
  • Know how to use cross-browser HTML5 JavaScript APIs
  • Understand current browser support for the various HTML5 features
  • Understand how to polyfill HTML5 features on older browsers

Our training takes a step-by-step approach, solidifying fundamental concepts and building on them to leave each attendee with a more thorough understanding of HTML5. Using a 50% lecture / 50% lab format, attendees will be able to put the concepts they have just learned to use after each section.

  • HTML5 Overview
  • Using HTML5 Today
  • Markup
  • Forms
  • Canvas
  • Video and Audio
  • Drag and Drop
  • Geolocation
  • Web Storage
  • Web Workers
  • Communication and Web Sockets

This course is designed for software developers interested in designing, creating, and deploying HTML5 web applications. It is valuable to developers that already have experience in developing web applications. To get the most out of the course, you should be familiar with HTML, CSS, and JavaScript.

Prior exposure to any of these concepts will be helpful, but not required: AJAX, XML, jQuery, HTTP, REST.

It’s short notice, but we hope you can make it, so register now! As always, feel free to email events@jquery.org with any event related questions.

See you all at the show!

jQuery 1.6.3 Released

Posted on by

jQuery 1.6.3 is now out! This is the third minor release on top of jQuery 1.6 and lands a number of fixes for bugs, as listed below.

As usual, we provide two copies of jQuery, one minified and one uncompressed (for debugging or reading).

You can help us by dropping that code into your existing application and letting us know if anything no longer works. Please file a bug and be sure to mention that you’re testing against jQuery 1.6.3.

Many thanks to all the people who reported bugs, submitted patches, and otherwise helped with this release! We want to encourage everyone from the community to get involved in contributing back to jQuery core. We’ve set up a full page of information dedicated towards becoming more involved with the team. The team is here and ready to help you help us!

Highlights

Fix an XSS attack vector: User ma.la reported a common pattern that many sites are using to select elements using location.hash that allows someone to inject script into the page. This practice seemed widespread enough that we decided to modify the selector recognition to prevent script injection for the most common case. Any string passed to $() cannot contain HTML tags (and thus no script) if it has a “#” character preceding them. See the ticket linked above for more information and a test case.

No more animation “worm holes”: We had high hopes for the browser’s requestAnimationFrame API when we added support into version 1.6. However, one of the highest-volume complaints we’ve received since then relates to the way requestAnimationFrame acts when a tab is not visible. All the animations initiated when the tab is invisible “stack” and are not executed until the tab is brought back into focus. Then they all animate at warp speed! We’ve removed support for this API (which has no impact on the way you call jQuery’s animation features) and plan to incorporate it into a future version of jQuery.

Better handling of HTML5 data attribute names: The $().data() API serves double-duty, handling data for the internal use of jQuery and plugins in addition to reading initial values of HTML5 data- attributes. We’ve improved the ability to use HTML5 conventions such as converting camel-case to camelCase when needed. Remember, however, that the $().data() API only reads the HTML5 data- attributes initially, and does not keep subsequent data changes in sync with attributes for performance reasons. To update the actual attributes in the HTML markup, use .attr().

jQuery 1.6.3 Change Log

The change log of the 1.6.3 release:

Ajax

  • #9255: jQuery.parseXML error handling does not work in webkit browsers
  • #9854: Pass statusText through instead of “normalizing” it
  • #9887: jQuery.ajaxSetup may cause unnecessary memory usage

  • #10098: Encode comment-like Accept headers to avoid mobile carrier mangling

Attributes

  • #9630: foo.contents().hasClass() returns incorrect value
  • #9699: removeAttr(‘style’) does not consistently remove the style attribute in webkit

  • #10021: Can’t add negative numbers using the relative-value syntax with .css() and .animate()

Data

  • #8235: jQuery.data throws a script error in certain circumstances
  • #9318: HTML5 data attributes has strange behaviour with if attribute names contain numbers
  • #9413: $.fn.removeData does not remove data with a dash in a name
  • #9779: Allow non-null|undefined evaluation of data property values
  • #9794: jQuery.fn.data() correctly handle access to arbitrary data property values
  • #10016: Cannot retrieve “false-y” values under key names with dashes using jQuery.data method
  • #10080: unload from frame’s window breaks in IE8

  • #9964: test/support.js module strictEqual typo
  • #10029: $.support.scriptEval removed, but still included in documentation

Please do file a bug report with a test case as soon as possible if you find problems, as described above. Blog comments or Twitter aren’t helpful bug reports!

jQuery 1.6.3 RC1 Released

Posted on by

jQuery 1.6.3 is almost ready to roll! We need your help with this release candidate to be sure we’ve got everything right.

Feel free to do your testing by including either one of these files (one minified and one uncompressed). Our preferred venue for test cases is jsFiddle; you can just use the “jQuery (edge)” selection there. If you need to report a bug and cannot use jsFiddle, please use the uncompressed version with your test case.

Please test this release with your most treasured code. If you find any important differences from 1.6.2, please file a bug as soon as possible and be sure to mention that you’re testing against jQuery 1.6.3 RC1.

If you’re making a quantum leap from a much older version of jQuery, it’s possible that the differences you find are due to documented behavior changes introduced in a major-point release. Check your code with the released 1.6.2 version first to be sure the problem only exists in 1.6.3 RC1.

jQuery 1.6.2 Released

jQuery 1.6.2 Released

jQuery 1.6.2 is now out! This is the second minor release on top of jQuery 1.6 and lands a number of fixes for bugs.

As usual, we provide two copies of jQuery, one minified and one uncompressed (for debugging or reading).

You can feel free to include the above URLs directly into your site and you will get the full performance benefits of a quickly-loading jQuery.

You can help us by dropping that code into your existing application and letting us know that if anything no longer works. Please file a bug and be sure to mention that you’re testing against jQuery 1.6.2.

We want to encourage everyone from the community to try and get involved in contributing back to jQuery core. We’ve set up a full page of information dedicated towards becoming more involved with the team. The team is here and ready to help you help us!

Registration Open for jQuery Conference in Boston!

Posted on by

Hey everyone!

We recently announced the dates for our next jQuery Conference—October 1st and 2nd in Boston, MA—and we’re finally ready to open registration! Here are some top level bullet points for you:

  • 2 days of jam-packed content from the jQuery Core Team and top community members, covering everything from jQuery basics and advanced techniques, to jQuery UI, jQuery Mobile, and more
  • A new limited-run jQuery tshirt and other jQuery swag
  • A fabulous Boston after party, hosted by our friends over at MediaTemple with free booze, snacks, great company and more
  • Other sweet after-hours events, announcements coming soon

Back by popular demand, we’ve also got a full day of Beginner jQuery Training for the new folks on your team, generously provided by our friends over at Bocoup. We’ll likely be adding additional topical and/or advanced training sessions, so keep an eye here and on Twitter for announcements and updates on that.

New for this year: For the first time ever, we’ve really got an official jQuery Conference Hotel. We’ve had suggested multiple hotels in the past, but this year we’ve secured a fantastic block at the conference venue, arranged for the Core Team and speakers to stay there, and have also thrown in some hotel-guest-only perks, like priority registration and swag distribution. We’ll also be organizing some on-site evening gatherings at the hotel, and hotel guests will receive priority registration for any of those as well.

The room block we secured last year—which didn’t have these extra perks—sold out well before the conference, so make sure you book your room ASAP, and make sure it’s part of our specific room block.

The Call for Papers is still open, so if you haven’t submitted your talk yet, definitely get on that.  Speakers receive access to a fantastic speaker thank you dinner, free accommodations at the conference hotel, and if budget allows it, additional TBD renumeration.

That’s it for now; we’ll have more announcements soon as we roll out the speaking roster, announce more party details and finalize all the other conference-related goodness.

More information

We’re aware that, unfortunately, this year’s Boston conference overlaps JSConf.eu. We considered a number of dates, but had to settle on the 1st and 2nd. We are truly sorry if this presents a conflict for you and hope you can enjoy a weekend of JavaScript on either side of the Atlantic.
