jQuery 1.1.2

Posted on by

Translations: Italiano, français

The release of jQuery 1.1.2 is upon us! This is a another bug fix release. We’ve fixed a number of outstanding issues. The fixes have been tested well, so there shouldn’t be any regressions (knock on wood). The most noticeable issue that was resolved was related to animation flickers when doing a slideDown.

It is highly recommended that you upgrade.

As always, if you have any questions or concerns with new release, please feel free to discuss it on the jQuery Mailing List. If you think you’ve spotted a bug, please add it to the bug tracker.


Bug Fixes

The most important bug fixes, relevant to this release, are as follows:

  1. Change: Event handlers (like element.onclick) are now removed when no more functions are bound to the event.
  2. Fixed: DOM Manipulations for form elements.
  3. Fixed: jQuery.isFunction to return false on nodes.
  4. Fixed: jQuery.className.has, escaping regex characters in className (for metadata)
  5. Fixed: an issue in IE where an event on a cloned element is fired during a .clone() inside of an event handler.
  6. Fixed: IE ID selectors selecting by the name attribute.
  7. Changed: Events are now internally stored in elem.$events rather than elem.events (due to a nasty bug relating to DOM 0 expandos).
  8. Changed: .attr('href') is now consistent in all browsers.
  9. Changed: @href is now consistent in all browsers.
  10. Fixed: the slideDown flickering bug.
  11. Fixed: Having a \r endline in $("...") caused a never-ending loop.
  12. Fixed: IE6 AJAX memory leak
  13. Fixed: bug in pushStack, reporting an element at [0] in a jQuery object with length 0


Additionally, the documentation has been back-ported out of the wiki and into the API docs. All of the documentation resources have been updated in respect to the 1.1.2 release.

Leading up to jQuery 1.1.3…

This may seem like a fairly light bug fix release, but we’re gearing up to the release of jQuery 1.1.3. A number of outstanding bugs (about 5-10) require significant changes to how jQuery works, internally (specifically, in relation to events and animations). We want to make 100% certain that there are no regressions made to these important pieces of code.

We have patches nearly ready (animation is ready, events is in the works) – and when that’s the case, we’re going to release a preview of the 1.1.3 code so that everyone can test against it.

Update: This has also been announced on Learning jQuery: jQuery 1.1.2 Released

Update: A nasty glitch in Safari was found and fixed. We just re-tagged jQuery (it’s now SVN rev 1465 instead of 1460 – this includes a fix for the bug, and it temporarily disables the test suite in Safari) and all the jQuery 1.1.2 downloads should be updated, as well.

jQuery is OpenAjax Compliant

Posted on by

OpenAjax Alliance

A new initiative has been forming, over the recent months, in an attempt to standardize the different Ajax and JavaScript codebases that exist. A number of corporate entities have come together to draft the new OpenAjax standard (including IBM, Adobe, Opera, and Mozilla).

Today we’re announcing a new plugin that you can use to make jQuery OpenAjax compliant. By doing this, jQuery is becoming one of the first projects that has made its codebase compliant with the new standard.

Currently, the requirements for compliance are, relatively, simple – but still quite important. The relevant rules can be summarized as such:

  • All libraries must register themselves (their name, version, and namespace) with the main OpenAjax library.
  • All libraries must register any global variables that they use (in the case of jQuery it’s ‘jQuery’, and optionally ‘$’ – it defaults to just including ‘jQuery’).
  • Any attempt to register “onload” or “onunload” handlers must go through the OpenAjax library. In the case of jQuery, if you do: $(window).load(function), and OpenAjax is included, jQuery will defer to OpenAjax’s solution.
  • Libraries must not disrupt the ability of other libraries to traverse the HTML DOM document.

You can view jQuery’s compliance results, to verify that it does, indeed, past the test suite.

If you wish to use jQuery in conjunction with other OpenAjax-capable libraries, the process is rather straight forward.

Step 1 Download a copy of the jQuery OpenAjax plugin to your server.

Step 2 Include the library in your site, just after you include jQuery.

<script src="jquery.js"></script>
<script src="jquery.openajax.js"></script>

Be sure to include both jQuery and the jQuery OpenAjax plugin after you’ve included the official OpenAjax library itself.

And that’s it! jQuery will now happily play with the OpenAjax core library.

It should be noted that, currently, jQuery is not part of the OpenAjax Alliance, but we’re in the process of applying and are eager to begin actively participating.

jQuery and Jack Slocum’s Ext

Posted on by

Ext JavaScript Library

Today, we’re proud to announce that the jQuery Project and Jack Slocum’s Ext Project, have partnered to integrate the amazingly lightweight and powerful jQuery framework with Ext’s awesome UI library. This collaboration will greatly enhance the capabilities of both projects and expand the functionality available to developers using the jQuery JavaScript Library and the Ext UI component suite.

Specifically, the upcoming Ext 1.0 release will be able to run, natively, on the jQuery JavaScript Library. No other libraries will be required. The jQuery and Ext teams are actively working together to bring this integration to the Ext codebase.

Here’s some possible questions and answers (feel free to post any others that you have in the comments):

What prompted the collaboration?

Ext has some fantastic components – arguably, the best on the web. jQuery has all the core functionality to support what Ext has. The jQuery team contacted Jack Slocum with the hopes that we could work together to add jQuery support to the Ext library, and Jack whole-heartedly agreed. It’s a win-win situation: jQuery gets some awesome components, Ext gets a huge influx of new users.

What are the benefits for jQuery and Ext users?

jQuery users gain a huge number of expertly-designed components that they will be able to deploy immediately. Additionally, they’ll be able to use them in a manner that better suits the jQuery philosophy (e.g. being able to call Ext queries on sets of elements, chaining calls, leveraging jQuery’s support for true unobtrusive DOM scripting etc.)

At the same time, existing Ext users will gain the flexibility of being able to continue to use Ext’s professional-caliber components while leveraging the lightweight, small (~19k) and powerful jQuery framework.

How will the two teams work together?

After the first beta release of Ext 1.0, jQuery will be providing a
strike team which will work to iron out all the integration points in Ext. At the same time, Jack will be working to isolate all the remaining framework-specific code, making it easier for us to finish the conversion process. All of this will be in place for Ext’s final 1.0 release, which will support both Yahoo UI and jQuery.

How will support be handled?

The jQuery team will be providing support for any bugs that may only exist in the jQuery version of Ext.

Support for Ext, itself, will continue to be handled via the Ext forums. The Ext project will also begin offering a level of paid support for its corporate users.

What Ext features will be included in Ext 1.0 for jQuery

All available Ext 1.0 features are going to be supported by jQuery.

The final feature list, for Ext 1.0, is still being finalized but a full breadth of new functionality can be expected.

When will Ext 1.0 for jQuery be available?

The final release date still has yet to be finalized and we will make a formal announcement on the jQuery blog, the jQuery mailing list, the Ext project site, and the Ext forums once the its ready to go.

An alpha release of Ext 1.0 was just released, but does not, yet, include the jQuery compatibility layer.

Do any licensing issues exist?

No. jQuery’s licensing will remain the same, and Ext 1.0 will be completely open source (LGPL).

Additionally, corporations will be able to purchase an Ext support license. This will include email support and SVN access, amongst other features.

Update: Digg this story up!


Here are examples of what you can do with Ext. (All demos currently run on Yahoo UI, as the Ext 1.0 alpha release doesn’t support jQuery.)

The jQuery IRC Channel

Posted on by

In addition to jQuery’s great Mailing List and Documentation, there’s another place where users can seek help about jQuery problems: We have a very active jQuery IRC channel.

Even though it’s never really been publicly announced, the channel currently averages over 50 simultaneous users, including some friendly jQuery bots! Hosted on irc.freenode.net, #jquery always has users who are online and willing to answer your questions (of which, they are often answered within minutes of their being asked).

Here’s the information that you will need in order to connect to the channel:
Server: irc.freenode.net
Room: #jquery

jQuery team members, especially John Resig (nick: JohnResig), Joern Zaefferer (nick: JoernZaefferer), and Yehuda Katz (nick: wycats) are frequently in attendance, helping experienced and new users alike with both complex and trivial problems.

The IRC Channel is best if you need quick help with any of the following:

  • JavaScript
  • jQuery Syntax
  • Problem Solving
  • Strange bugs

If your problem is more in-depth, we may ask you to post to the mailing list, or the bug tracker, so that we can help you in a more-suitable environment.

Additionally, we recently started logging the channel, so you can now look back through to find answers to your old problems: jQuery IRC channel Log

jQuery Nightly Builds

Posted on by

After much wailing and gnashing of teeth by certain members of the discussion mailing list (read: me), we now have automated nightly builds of jQuery ready for mass consumption. These builds came about at the request of we community members who would like to experiment with the most recent features of jQuery on our projects, but who, for whatever reason, find ourselves behind firewalls that restrict our access to the subversion repository.

Without further ado, here are the gory details: You can get your bleeding-edge-jQuery fix at http://jquery.com/src/nightlies/. This folder will simply show you a list of available files. There are 4 files in there in which most of you will be most interested…

  1. jquery-nightly.js – Pretty self-explainatory. It’s the uncompressed jQuery. Mmmm… fresh from the repository
  2. jquery-nightly.pack.js – As the more perceptive of you have already guessed, it’s the packed version of #1
  3. jquery-nightly.release.zip – This contains the docs, test suite, and all of the pre-built versions of jQuery
  4. jquery-nightly.build.zip – Is the real win for we poor souls behind the fiery-walls of the corporate world. It contains the full jquery path from the repo, and is everything you need to build your very own jQuery

The nightlies folder will also fill up with dated versions of all 4 of these files so that you can go find jQuery at whatever vintage you prefer.

New versions of the nightlies will be added every day at 2am EST (7am GMT), and will consist of the most recent revision from the subversion repository at that time.

If all of this talk of subversion, repositories, bleeding-edge, and nightly building makes the stability craving web deveoper inside you run away screaming, fear not. The stable release download you need is still right here waiting for you.

Thanks go to John Resig for hooking us up with the server-side magic that got this automated build process running (not to mention for the server, the bandwidth, and for jQuery in general :) ).

New jQuery Project Team Members

Posted on by

The jQuery team would like to welcome our newest team members, Yehuda Katz, Nate Cavanaugh, & Klaus Hartl. These three developers have made invaluable contributions to the jQuery projects in terms of time, knowledge and commitment to the community.

Yehuda is a developer living in New York City who maintains the web site Visual jQuery, and publishes the Visual jQuery Magazine. Additionally, he’s a frequent contributor to the jQuery Blog and promoter of good practices within the jQuery core. As a member of the evangelism team he’s working to help people discover jQuery; actively trying to find and promote jQuery to new users.

Nate is a designer living in California. He was responsible for the recent redesign of the jQuery site. He’s going to be helping to design new portions of the site, and help to bring outdated portions of the site inline with the rest. He’s also working to take a critical look at how using jQuery, as a design tool, can help to promote Unobtrusive design principals.

Klaus has been one of the most vocal supporter of jQuery and unobtrusive design on the jQuery mailing list. His ability to expertly explain quality, unobtrusive, solutions to problems is invaluable will be a tremendous boon to the jQuery project. Klaus will be working with both the Evangelism & Dev teams, to help promote jQuery and expand its reach as well as maintaining Thickbox and the Tabs plugin. He will also be spearheading the effort to make Tabs an official plugin.

We’re very pleased to be working with all of you and welcome you to the jQuery team.
