jQuery 1.4.4 Released

Posted on by

jQuery 1.4.4 is now out! This is the fourth minor release on top of jQuery 1.4 and lands a number of fixes for bugs including some nice improvements over 1.4.3.

We would like to thank the following community members that provided patches, input and their time towards this release: Rick Waldron, Dan Heberden, Alex Sexton, Colin Snover.

Along with the following members of the jQuery core team: John Resig, Dave Methvin, Karl Swedberg, Paul Irish.

We also thank our bug triage team who assisted in narrowing down some of the important fixes needed for this release: Colin Snover, Rick Waldron, Addy Osmani, Alex Sexton, Adam Sontag, Dave Methvin, Mike Taylor, Aaron Boushley, Jitter and John Resig.


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

General Improvements

We’ve made a number of improvements with this release, many of which have fixed bugs that were highlighted by the jQuery Community. For the complete list of changes, see the section below marked ‘Changes’ for more information.

New Features

All new features and changes can be found in the jQuery API documentation for 1.4.4.


In an attempt to further unify the methodology across our API, we’ve introduced a new method to Effects called .fadeToggle(). We already have existing toggle methods in our API for sliding (.slideToggle()) and toggling classes (.toggleClass()) and it made sense for us to extend the availability of a built in toggle to fading effects as well. See the API documentation on .fadeToggle() for more information.


What’s Been Updated?

There are a few areas in jQuery that have seen changes since 1.4.3 was released:

  • (New) Added a new animation method, .fadeToggle()
  • (Enh) Calling .data() with no arguments now includes data from HTML5 data- attributes (#7222)
  • (Enh) Moved jQuery.props from support.js to attributes.js (#6897)
  • (Enh) .width() and .height() now report the width and height of hidden elements (#7225)
  • (Bug) stopImmediatePropagation was not being honoured in live/delegate event handlers (#7217)
  • (Bug) Fixed an issue where host and protocol were not compared case-insensitively when determining whether an AJAX request was local or remote (#6908)
  • (Bug) Fixed an issue where the “clone” variable was not being declared correctly (#7226)
  • (Bug) Fixed a bug where we only change the ID on nodes that don’t already have an ID for rooted qSA (#7212)
  • (Bug) Limited the scope of the CSS ‘auto’ change to just height/width (#7393)
  • (Bug) Fixed a bug to ensure that unquoted attribute selectors are quoted (allowing them to go into qSA/matchesSelector properly). Fixes (#7216)
  • (Bug) Fixed a bug to ensure that if additional load events are triggered (eg. an iframe being dynamically injected in DOM ready) the ready event isn’t triggered twice (#7352).
  • (Bug) Fixed a condition that prevents attr from working on non-Element nodes (#7451).
  • (Bug) Changing an HTML5 data attribute after calling .data(‘foo’) no longer causes .data(‘foo’) to also change (#7223)
  • (Bug) Fixed a bug where Opera didn’t give height/width of display: none elements with getComputedStyle but did with currentStyle – fall back to that if it exists added.
  • (Bug) Fixed a bug to ensure accessing computed CSS for elements returns ‘auto’ instead of ” consistently (#7337)

It also fixes a number of regressions in 1.4.3. One that caused:

  • (Bug) JSONP calls to fail when cleaning up after a callback (#7196)
  • (Bug) .removeData() to fail (#7209)
  • (Bug) “ready” events to fire twice when added using .bind(“ready”, foo) (#7247)
  • (Bug)  .css(‘width’) and .css(‘height’) to return 0 or negative values when trying to get the style of a hidden or disconnected element (#7225)
  • (Bug) the attribute not equals selector ([foo!=bar]) to not work in Firefox (#7243)
  • (Bug) find() to fail when selecting from forms containing inputs named “id” (#7212)
  • (Bug) .children(selector) to fail on XML documents (#7219)
  • (Bug) child (>), next sibling (+), and previous sibling (~) selectors to fail when combined with non-CSS pseudo-selectors like :last (#7220)
  • (Bug) an error “handler is null” to be raised when passing null as the event handler (#7229)
  • (Bug) it to be impossible to include a content-body with DELETE requests (#7285)
  • (Bug) it to be impossible to include data with HEAD requests (#7285)
  • (Bug) an issue where IE was firing click events on disabled elements when using live/delegate (#6911)
  • (Bug) .show() to fail if .hide() was first called on an already-hidden element (#7331)
  • (Bug) .show() to fail if an element was hidden in a stylesheet, then had .css(‘display’) manually set prior to calling .show() (#7315)

Backwards-incompatible changes in jQuery 1.4.4

The .width() and .height() methods no longer return 0 when inspecting an element hidden using ‘display: none’. To determine if an element is hidden, always use .is(‘:hidden’).

and that’s it!. jQuery 1.4.4 is now out so feel free to update your projects to use the latest version. We welcome any and all feedback from the community.

What Features Would You Like To See In jQuery 1.5?

Now that jQuery 1.4.4 is out, we’re starting the process of planning our next major release and we would like the community’s help in deciding what features we should include. The process for suggesting a feature is quite straight-forward; here’s what you need to do:

1. Think of a feature you would like included in jQuery 1.5
2. Create a new ticket for that feature in our [bug tracker] if one does not already exist
3. Send your nomination by filling out the [jQuery 1.5 feature nomination form]

Thats it! In a couple of weeks the jQuery team will be sitting down to review all nominations. The features that we think would benefit the majority of the community will be added to our roadmap.

We’re aiming to release jQuery 1.5 early next year and we appreciate any help you can provide in letting us know how we can improve it for you. We look forward to hearing your ideas and feature requests.

The Official jQuery Podcast has a New Home

Posted on by

Today, we’d like to announce that we’ve moved the Official jQuery Podcast off the jQuery blog and onto it’s own site at http://podcast.jquery.com.

We felt that with a weekly blog post for each episodes show notes the podcast was taking over the blog.  Some of the community members thought the same way.  We’ve been working on porting over the existing posts and making the new podcast site easier to use for our listeners.

Each episodes show-notes are now streamlined to give you a quick introduction about what the show is about followed by all the links that were mentioned in the show.  We also have the ability to play the show from the post with an embedded player as well as easy links to download and subscribe.

We also have a easy contact form that will allow you to contact the podcast directly.

We’ve cleaned up the jQuery blog and removed the old show notes and put in place URL redirects so old urls will still go to the right post on the new site. While we are talking about the blog, we’d like to know what would you like to see more of on the jQuery blog?  Currently we’ve been using the blog to post news about the project and upcoming events.  What else can we post to help you out?  We’d love to hear your ideas.

Special thanks goes out to Doug Neiner for helping out with design and coding, also, would like to thank Jonathan Sharp for setting up the site and getting the URL redirects in place.

Let us know what you think of the new podcast site and don’t forget to keep listening to the show.

jQuery 1.4 Alpha 2 Released

Posted on by

jQuery 1.4 Alpha 2 is released! This is the second alpha release of jQuery 1.4 (alpha 1 was released previously). The code is stable (passing all tests in all browsers we support), feature-complete (we’re no longer accepting new features for the release), and needs to be tested in live applications.

Grab the code:

NOTE: If you’re using jQuery 1.4a2 and you run into an error please make sure that you’re using the regular version of the code, it’ll make it easier to spot where the error is occurring.

How can I help?

To start, try dropping the above un-minified version of jQuery 1.4a2 into a live application that you’re running. If you hit an exception or some weirdness occurs immediately login to the bug tracker and file a bug. Be sure to mention that you hit the bug in jQuery 1.4a2!

We’ll be closely monitoring the bug reports that come in and will work hard to fix any inconsistencies between jQuery 1.3.2 and jQuery 1.4.

With your input we should be able to produce a solid release. Right now we’re looking to push out at least one beta around the beginning of the new year and a final release candidate early in January. The final release will occur on January 14th, coinciding with jQuery’s 4th birthday. Thanks for your help in reviewing jQuery 1.4a2!

jQuery 1.4 Alpha 1 Released

Posted on by

Hot off the presses: jQuery 1.4 Alpha 1 is released! This is the first alpha release of jQuery 1.4. The code is stable (passing all tests in all browsers we support), feature-complete (we’re no longer accepting new features for the release), and needs to be tested in live applications.

Grab the code:

NOTE: If you’re using jQuery 1.4a1 and you run into an error please make sure that you’re using the regular version of the code, it’ll make it easier to spot where the error is occurring.

How can I help?

To start, try dropping the above un-minified version of jQuery 1.4a1 into a live application that you’re running. If you hit an exception or some weirdness occurs immediately login to the bug tracker and file a bug. Be sure to mention that you hit the bug in jQuery 1.4a1!

We’ll be closely monitoring the bug reports that come in and will work hard to fix any inconsistencies between jQuery 1.3.2 and jQuery 1.4.

What to Watch For

There are a few areas in jQuery that have seen extensive changes since 1.3.2 was released:

  • live was drastically overhauled and now supports submit, change, mouseenter, mouseleave, focus, and blur events in all browsers. Also now supports context and data.
  • append, prepend, etc. have been heavily optimized.
  • add has been adjusted to always return elements in document order.
  • find, empty, remove, addClass, removeClass, hasClass, attr, and css have been heavily optimized.

Full details concerning the release are forthcoming – for now we just need your help in catch regressions. Some more details can be found in John Resig’s keynote at the 2009 jQuery Conference.

Note: There are still a few open bugs that we will be reviewing before jQuery 1.4 final is released.

With your input we should be able to produce a solid release. Right now we’re looking to push out at least one more alpha before the holiday season and a final release candidate early in January. Thanks for your help in reviewing jQuery 1.4a1!

jQuery Wins .Net Magazine Award

Word has just come in that jQuery has won the 2009 .Net Magazine Award for best Open Source Application. jQuery was in the final voting with Firefox and WordPress.

Simon Willison graciously accepted the award for the team:


This award really goes out to the whole jQuery community and all the contributors that made jQuery what it is today. Congratulations!

jQuery Joins the Software Freedom Conservancy

Posted on by

You’ve been hearing for almost a year now that the jQuery Project was going to join the Software Freedom Conservancy.  As we stated on January 14th, 2009:

By joining The Software Freedom Conservancy, the jQuery projects and community immediately realize some important benefits:

  • It allows the current project members to continue to manage the projects and maintain ultimate responsibility for the direction of current and future efforts.
  • It allows the projects to be considered a true non-profit efforts allowing us to be able to accept donations and contributions without incurring tremendous personal financial liability.
  • The copyright of the code will be assigned to the conservancy thus ensuring that no single person will own contributions or assets of the project.
  • It may allow corporations to write off time when an employee contributes to a project.
  • Most importantly, it ensures that the jQuery projects will always be open and free software.

This is a big step in formalizing the jQuery projects and an important accomplishment in ensuring that the investment being made by the jQuery community is protected.

The Software Freedom Conservancy outlines the benefits of joining quite well:

One of the principal benefits of joining the Conservancy is that member projects get all the protections of being a corporate entity without actually having to form and maintain one. These benefits include, most notably, the ability to collect earmarked project donations and protection from personal liability for the developers of the project. Projects can continue to operate in the same way they did before joining the Conservancy without having to select a board of directors or any other layer of corporate management, without having to maintain corporate records and without having to do any of the other things required of incorporated entities. The Conservancy handles all of that burden on behalf of its projects.

The Conservancy is a tax-exempt 501(c)(3) organization, so member projects can receive tax-deductible donations to the extent permitted by law. The Conservancy files a single tax return that covers all of its member projects and handles other corporate and tax related issues on behalf of its members, who are, of course, always free to join and leave the Conservancy at any time. Additionally, by not having to form a new organization, projects avoid having to pay the fees and spend the time required by the state incorporation and federal tax exemption application processes.

On September 11th, 2009, at the jQuery DevDays in Boston, MA the whole team was together and the documents were signed to officially join the Conservancy.

jQuery Team Signs Documents to join Software Freedom Conservancy

Since then we’ve formed the jQuery Project and have formalized a voting process to vote on adding or removing voting members, financial spending, etc.  Voting is done in public, and you can monitor votes here.

jQuery’s financials have also been transferred to the Conservancy and all your great donations are now managed by the Conservancy based on the direction of the voting members of the jQuery team.

Late last month the final details required by the Conservancy were ironed out and on Tuesday this week the Conservancy welcomed the jQuery Project as its 19th member.

One final detail we are still working on is transferring the copyright of the code to the Foundation.  We are hoping to get that done in the near future.  Transferring the copyright to the Foundation will ensure that the code will live forever.

You can listen to John Resig talk more about joining the Software Freedom Conservancy in Episode 1 of the Official jQuery Podcast.
