We’ve just pushed out a brand new site redesign (for jQuery.com and all its sub-sites). This has been a long time coming and it feels great to get it out the door.

New Homepage

Easily the most contentious part of the redesign – but absolutely the most eye-catching.

jQuery has long been driven by rock, even looking back to its original release which was heavily inspired by the always-excellent Devo. We shot for a catchy design that helped to bring JavaScript out of the cold doldrums that it frequently inhabits – giving it a serious jolt of fun.

New Site Layout

The entirety of the site has a new layout. With drastically improved multi-layer navigation and a standardized sidebar it should become much easier to navigate the individual portions of the site.

You should probably wear a hard hat while exploring the interior pages – font sizes, spacing, and colors are all in need of tweaking, which will be handled over the upcoming week (it’s fun working against Trac, WordPress, Drupal, and Mediawiki simultaneously).

New Logo

The original jQuery logo was a variation of the Devo hat – we’ve taken that concept, turned it on its ear, and made it something that we can call our own – while still being inspired by the original contours of the Devo Energy Dome.

Thanks

Site and Logo Design: Scott Jehl – he put a fantastic amount of work into this redesign, bringing it all the way from conception to final implementation.

Rockin’ Illustration: Varick Rosete from nGenWorks also of Happy Webbies fame.

Initial Logo Prototyping: Bradley Sepos.

Also want to thank Media Temple for our hosting. They’ve been helping us a lot this past week migrating our sites to some new servers – expect some speed improvements for the sub-domains very soon.

About 4 days ago, many have noticed that we had uploaded another minor bugfix release to our Google Code account. While there’s, again, no new API introduced, more than 30 issues have been cleared and the codebase is growing more stable every day.

The full changelog is available here if you want to find out if a specific issue has been addressed. As with 1.5.1, updating to this version is highly recommended and likely not to break anything in your written code.

You can grab the latest release as always via the downloader or as developer package at http://ui.jquery.com/download or if you prefer, get it as latest tag from Subversion.

As a last comment, this is probably the last minor release before 1.6, which we will announce before the end of July, so watch out for a couple of awesome new components and enhancements soon!

Have a nice day,

Paul Bakaus & the jQuery UI Team

Soon after the release of jQuery UI 1.5, we were getting many useful feedback and issues entered in our bugtracker. Today, we’re happy to release another version of jQuery UI which takes care of many minor regressions and a lot of unsolved issues.

1.5.1 doesn’t add any new features or API changes, but fixes more than 50 found issues. A full changelog is available, if you want to know the specifics. Updating to this version is highly recommended and likely not to break anything in your written code.

Additionally, issues within ThemeRoller and the demos on our homepage also have been reported and fixed. We are now continuing to finish all unit tests and functional demos, so expect to see another release of both UI and its website soon again.

You can grab the latest release as always via the downloader or as developer package at http://ui.jquery.com/download or if you prefer, get it as latest tag from Subversion.

See you soon,

jQuery 1.2.6 is primarily a bug fix release for jQuery 1.2. You can view the full list of what was fixed on the bug tracker.

This is the next release immediately following jQuery 1.2.3. Releases 1.2.4 and 1.2.5 were skipped (1.2.4 was built incorrectly, rendering it effectively identical to 1.2.3, and 1.2.5 was missing a patch).

The entire jQuery team did a fantastic job in pulling this release together – I want to take this opportunity to thank them all for their continued hard work.

I’d also like to take this opportunity to welcome Ariel Flesler to the core jQuery development team. He provided valuable help in pulling this release together – contributing bug fixes, performance improvements, features, and test cases. You can see the result of his hard work all throughout this release. Welcome Ariel and thank him for all his contributions!

Downloading

jQuery 1.2.6:

• Recommended Hosted Code with Google: AJAX Libraries API

If you wish to checkout the full release from the Subversion repository, you can do so by following the instructions and checking out the source from the following location:

svn co http://jqueryjs.googlecode.com/svn/tags/1.2.6

Performance Improvements

Once again the jQuery team has worked hard to bring huge performance improvements in this release. As with previous releases we’ve expanded to look at many areas of the jQuery framework, looking for common pain points, and providing relief.

All data and test cases for the below performance improvements can be found in the the following jQuery 1.2.3 v. 1.2.6 Google Spreadsheet (results for Internet Explorer 6 were excluded in favor of Internet Explorer 7 due to their virtually-identical results).

Event Handling is 103% Faster

In analyzing intense application code (specifically operations such as drag-and-drop) we looked for ways in which universal changes could be made that would affect all users. A frequently-called piece of code was that of the jQuery event handler, any optimizations to it would dramatically improve the performance of all resulting frequently-called events. By focusing improvements here all frequently-called events that you have should see immediate benefits.

CSS Selectors are 13% faster

A number of optimizations have been made to internal jQuery methods, dramatically improving their performance, while providing measurable benefit to some of the most commonly used code in jQuery (such as the CSS Selector code).

For example the jQuery.map() method is now 866% faster and jQuery.extend() is 19% faster. These two changes have allowed for dramatic improvements in performance all throughout the library.

.offset() is 21% faster

Together with the improvements to jQuery’s event handling code optimizations of .offset() have allowed intense mouse-based operations to become much faster. For example jQuery UI’s drag-and-drop code is now over 300% faster because of these change (allowing you to achieve faster, smoother, drag-and-drop operations).

.css() is 25% faster

A method that’s frequently called (both internally and externally). The optimizations to this method are easily felt in others (like .offset(), for example).

New Features and Major Changes

Dimensions Plugin is Now Part of Core

The remaining methods of the Dimensions plugin, by Brandon Aaron, have been introduced into jQuery core, along with additional bug fixes and performance improvements. This plugin has seen considerable use amongst developers and plugin authors and has become a solid part of the jQuery ecosystem. We’ve been, slowly, introducing the most-used methods from the Dimensions plugin over the past couple releases – but with the release of 1.2.6 all remaining methods are now part of core.

If you’re upgrading your copy of jQuery to version 1.2.6 you can now opt to exclude the Dimensions plugin from your code.

The full documentation for Dimensions can be found on the jQuery documentation site (and is in the process of becoming integrated with the core jQuery documentation).

.attr() overhaul

The .attr() method has been completely overhauled (resolving about 15 outstanding bugs). Additionally, the method has been significantly simplified and optimized.

.toggle() can now accept more functions

Historically jQuery’s .toggle() function has accepted two functions (to be toggled in an even/odd manner). However that has been changed so that any number of functions can be provided and toggled by a mouse click.

$("div").toggle(function(){
  $(this).removeClass("three").addClass("one");
}, function(){
  $(this).removeClass("one").addClass("two");
}, function(){
  $(this).removeClass("two").addClass("three");
});

You can now unbind bound .toggle() and .one() functions

function test(){ $(this).addClass("test"); }
$("div").one("click", test);
$("div").unbind("click", test);

$("div").toggle(test, test);
$("div").unbind("click", test);

.index() supports jQuery collections

jQuery’s .index() function has allowed you to find the location of a DOM element in the jQuery collection – now you can also specify a jQuery collection (the first element of which will be extracted and located in the original set).

var test = $("div.test");
$("div").index( test ) == 3

jQuery.makeArray can convert ANYTHING to an array.

jQuery’s internal .makeArray() method now converts any array-like object into a new array. Additionally it wraps all other objects as an array and returns the resulting set.

jQuery.makeArray( document.getElementsByTagName("div") )
// => [ div, div, div ]

jQuery.makeArray( true )
// => [ true ]

jQuery.makeArray()
// => []

beforeSend can cancel Ajax calls

The beforeSend Ajax callback has allowed developers to execute a piece of code prior to a request occurring – now that code can also verify the integrity of some parameters and cancel the resulting Ajax request (useful for tasks like form validation).

$.ajax({
  beforeSend: function(){
    return $("#input").val() == "";
  },
  url: "test.php"
});

Exposed Speeds

jQuery has a number of named animation speeds (such as ‘slow’, ‘fast’, and ‘default’) you can now provide your own names for animation speeds, or modify the existing ones, by manipulating the jQuery.fx.speeds object.

jQuery.fx.speeds.slow = 1000;
$("#test").slideDown("slow");

The jQuery 1.5 release candidate is now available at http://ui.jquery.com/download for everyone to test and download!

This is the most stable UI version ever, and it fixed all known bugs that are not in the categories “minor” or “trivial”, which means that we ourselves think it’s good to go. However, the reason why we’re still holding off with the final release is the fact that we want you to try out every aspect of our release candidate.

Therefore, the jQuery UI team encourages you to try out the demos on the website in any of the supported browsers, play around with every option you can find and test in different browsers using the new unit tests, which we’re finalizing right now. If you grab the whole development package from the website, it will come with unit tests for slider, draggables and resizables. We are working on other automated tests, which can be downloaded in the next few days from our SVN.

If you find anything strange going on, or if something isn’t working / looking like it should, that’s great :-) ! Please then submit your issue to us via the new jQuery UI bugtracker at http://ui.jquery.com/bugs/newticket. This will greatly help us to make the final release as solid as possible.

Now we really don’t want you to wait any longer than needed: I’m very excited to announce that jQuery UI 1.5 will be released and announced in exactly 6 days, on June 8th, along with updated documentation and a epic changelog to convince your bosses and collegues.

See you soon!

The jQuery UI Team
