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:

$(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.

jQuery 1.6.4 RC1 released

Posted on by

jQuery 1.6.4 will be released soon, and we need your help with this release candidate to find any remaining bugs. We’re putting out a new version to address a few last-minute bugs that crept into the 1.6.3 release. With version 1.7 coming next month, we felt it was important to fix these bugs and finalize the 1.6.x line before making more extensive changes and feature additions.

Feel free to do your testing by including either one of these files (one minified and one uncompressed). If you find any important differences from 1.6.3, please file a bug as soon as possible and be sure to mention that you’re testing against jQuery 1.6.4 RC1. Our preferred venue for test cases is jsFiddle; you can just use the “jQuery (edge)” selection there.

jQuery 1.6.4 RC1 Change Log

The current change log of the 1.6.4 release:


  • #10194: Data attribute names with single dash-surrounded letters cannot be accessed by the camel-case name


  • #10208: $(“form”).live(“submit”, fn) not fired from <button type=”submit”> in IE8


  • #10197: Bug with mime-type application/xhtml+xml in jquery 1.6.3

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.


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 current change log of the 1.6.3 release:


  • #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
  • #9970: Typo in ajax.js: status should be jqXHR.status?
  • #10098: Encode comment-like Accept headers to avoid mobile carrier mangling


  • #9630: foo.contents().hasClass() returns incorrect value
  • #9699: removeAttr(‘style’) does not consistently remove the style attribute in webkit
  • #9719: removeAttr(‘disabled’) doesn’t change input’s color on IE6
  • #9979: .prop(‘tabIndex’) returns inconsistent results for elements that have not yet set tabIndex
  • #9980: Simplify the attr code by using getAttributeNode for everything in IE6/7


  • #9988: Minimal License Header in compressed jQuery


  • #9521: XSS with $(location.hash) and $(#) is needed?
  • #9897: try-catch isPlainObject detection
  • #10076: $.inArray crashes IE6 and Chrome if second argument is `null` or `undefined`


  • #6652: Remove filter:alpha(opacity=100) after animation
  • #9572: Support -ms-transform in .css() method
  • #10021: Can’t add negative numbers using the relative-value syntax with .css() and .animate()


  • #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


  • #10123: .width() can return a float in Firefox 6


  • #9381: Animations halt when the browser is out of focus due to requestAnimationFrame
  • #9678: setInterval cleared by animation


  • #7071: Accessing the ‘type’ property on VML elements fails on IE during submit special handler


  • #9587: Cloning a div with an object causes error in IE8


  • #9634: Visible “t” character in upper left corner during support.js init
  • #9823: IE 8 crashes when using background-image on BODY in css
  • #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!

New Releases, Videos & A Sneak Peek At The jQuery UI Grid

Posted on by

In today’s post we’ll be presenting updates on both jQuery Core and UI as well as highlighting any upcoming training events being held and articles or videos which we think might be useful to read. We would appreciate your comments and feedback on them!



jQuery 1.5 Was Released

This week, the core team released jQuery 1.5 to celebrate the fifth birthday of the library. This included many performance improvements and bug fixes as well as a major re-write of the Ajax module which now comes with deferred callback management. Core also introduced a new feature called jQuery.sub which allows for new copies of jQuery to be created where properties and methods can be safely modified without affecting the global jQuery object.

If you haven’t had a chance to read or play around with these new features as yet, community member Eric Hynds wrote an in-depth tutorial on using Deferreds which you may be interested in. I also recorded a quick screencast explaining how to use jQuery.sub.

jQuery 1.5 has already begun to be used in the wild and you may also be interested in taking a look at jQuery templating author Boris Moore’s new script loader which also makes use of deferreds.

As always, we appreciate any and all community feedback on the 1.5 release and if you discover bugs or issues which you would like to report, you can do so by following our bug submission guidelines. We’ve already made a number of fixes to 1.5 (which can be tested in jQuery-Git) and we also welcome any feedback on that version as well.

Remember that up-to-date information on all our future releases (including jQuery 1.5.1) can be found on our roadmap.


Unleashing the Grid – A New jQuery UI Grid

The jQuery UI Team have announced an exciting new project called the jQuery UI Grid, where they’ll be building a feature rich, fast grid widget for enhancing table data with linking, sorting, paging and inline editing amongst other features.

There have been quite a few attempts outside of the project to create such widgets before, however they’ve often suffered from poor support, documentation or a lack of extensibility – the new UI grid project aims to solve these issues by providing a project-supported component that will be both modular and continually updated.

Speaking to Richard D. Worth, here’s a progress update on where the team are with the Grid at the moment:

We are nearing completion of development on Stage 1 of the project, which encompasses the creation of a generic data model, data type parsing, and markup. This stage will culminate in a “zero feature grid,” an enhanced HTML table that supports the jQuery UI CSS Framework and serves as a base for other grid features.

Read Richard’s full blog post on the new Grid.


jQuery Conference Videos Are Now Available Online

CSS Hook Extensibility in jQuery 1.4.3+

cssHooks allow you to “hook” in to how jQuery gets and sets css properties. This means that you have the ability to create a cssHook to help normalize differences between browsers, or to add some missing functionality from the stock jQuery.fn.css(). David Petersen’s fantastic article on cssHooks caught our attention and we think it could come in useful in your projects.

Google CDN: https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js

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.
