jQuery Conference 2011 – Preconference Training

Posted on by

What started, with great demand, at the San Francisco Bay Area conference last year and has continued on for the conferences thereafter is our preconference training.  We are once again offering preconference training on April 15th for the jQuery Conference 2011: San Francisco Bay Area but for the first time offering two separate classes, beginner and advanced.

Introduction to jQuery given by Bocoup

BocoupBocoup gave a bunch of advanced and hack day training classes in Boston last year in addition to the preconference Introduction to jQuery class, which also was greatly attended.  We are very happy to announce that Bocoup will once again be giving the Introduction to jQuery class.

From Bocoup.com:

The training will be given by Ben Alman (the jQuery plugin guy) and Adam Sontag (the yayQuery guy), and has been designed to give attendees a basic understanding of the jQuery API, development techniques, and best practices. In addition, attendees will learn about both jQuery UI and jQuery Mobile, and will be given an introduction to extending jQuery with custom plugins.

As usual there is a limited number of tickets for this training class and they are selling fast.  You’ll need to hurry if you want a seat for this class.

Tickets for Beginner training are $299 (plus Eventbright fees) and all proceeds go directly to the jQuery Project.

Please make sure to thank Bocoup for their support.

Advanced jQuery given by Jupiter JavaScript Consulting

BocoupNew this year is an additional track for Advanced jQuery and we are happy to have Jupiter JavaScript Consulting give this class. JuptierJS builds and maintains JavaScriptMVC and has plenty of experience building complex jQuery apps.

From jupiterjs.com:

The following is a rough list of topics we’d like to cover.  I list them here quasi hierarchically.  But in reality, we’ll cover most of these topics throughout the day.

  • Application Design
  • Thin Server Architecture
  • State Management
  • History Enabled Websites
  • Widget Design
  • Event Oriented Architecture
  • Custom Events
  • Pub-Sub
  • Event Delegation
  • 1-2-3 Layers / Separation of Concerns
  • Organizing Ajax and the Domain Model
  • Deffereds
  • Ajax Fixtures
  • Client Side Templates
  • The Perfect jQuery Plugin
  • Prototypal Inheritance
  • File/Folder Organization
  • Dependency Management
  • Production Builds
  • Testing
  • QUnit, Jasmine, Selenium, FuncUnit, Waitr, etc
  • High Performance jQuery
  • Even More Design Reviews

Yes, that’s a whole lot to cover! So come and be prepared to have your mind blown (and let me know if there’s something else you’d like to learn).

As usual there is a limited number of tickets for this training class and they are selling fast.  You’ll need to hurry if you want a seat for this class.

Tickets for Advanced training are $399 (plus Eventbright fees) and all proceeds go directly to the jQuery Project.

Please make sure to thank Jupiter JavaScript Consulting for their support.

jQuery 1.5.1 Released

Posted on by

jQuery 1.5.1 is now out! This is the first minor release on top of jQuery 1.5 and lands a number of fixes for bugs.

We would like to thank the following contributors that provided patches towards this release: antonkovalyov, csnover, danheberden, davidmurdoch, dmethvin, gnarf37, jaubourg, jeresig, jitter, jrburke, lrbabe, mathiasbynens, rwldrn, SlexAxton, and voxwerk.

We’d especially like to thank our bug triage team who assisted in narrowing down some of the important fixes needed for this release.

Downloading

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.

Additionally you can also load the URLs directly from Microsoft and Google’s CDNs:

Microsoft CDN: http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.min.js

Google CDN: https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js

1.6 Roadmap Meeting

The core jQuery dev team is now taking proposals for changes to land in jQuery 1.6. Right now we’re shooting to release jQuery 1.6 late April/early May and will be meeting to discuss the submitted proposals at Noon EST on March 7th (the meeting will be in #jquery-meeting on irc.freenode.net).

Please submit your proposals through the following form in advance of the March 7th meeting.

jQuery 1.5.1 Changelog

jQuery 1.5.1 Test Swarm Results

API Documentation: jQuery 1.5.1 API Documentation

As this was a bug fix release there are no new features to report upon. The only changes are as follows:

jQuery now supports Internet Explorer 9 as a top level browser. All known bugs have been fixed and/or been reported to the IE team for resolution in the final release.

Three new options were added to jQuery.ajax():

  1. isLocal: Allow the current environment to be recognized as “local,” (e.g. the filesystem), even if jQuery does not recognize it as such by default. The following protocols are currently recognized as local: file, *-extension, and widget. If the isLocal setting needs modification, it is recommended to do so once in the $.ajaxSetup() method.
  2. mimeType: A mime type to override the XHR mime type.
  3. xhrFields A map of fieldName-fieldValue pairs to set on the native XHR object. For example, you can use it to set withCredentials to true for cross-domain requests if needed.

Closed Tickets

A full list of all bugs and tickets closed are as follows:

  • #2551 Make sure .val() works after form.reset() in IE
  • #4537 Make sure .clone(true) correctly clones namespaced events
  • #4966 Don’t add “px” to unit-less properties when animating them
  • #6774 Make sure we only access parentNode if it’s available. Fixes an issue where after an option tag has been detached, an elem.parentNode error would be thrown.
  • #6911Prevent action on disabled elements, both triggering and bound via .live()
  • #7531 Fix again for IE9RC. Enhances ajaxSetup so that it can take an optional target option, in which case target will be updated instead of ajaxSettings. That way, fields that shouldn’t be deep extended can be listed and dealt with in one place. jQuery.ajax now makes use of ajaxSetup with target to create its internal settings object
  • #7568 Follow-up fix for #5862. Objects with a length property weren’t serialized properly by jQuery.param
  • #7653 Changes regexp to detect local protocol so that it will accept any protocol finishing by -extension
  • #7668 Sizzle and jQuery QUnit tests are out of sync
  • #7912 This change makes .cur() more .cssHooks friendly. .cur() now returns the unmodified value by .css() if it isn’t a number, number-alike or a value that needs a fallback to 0.
  • #7922 Fixed an issue where live(‘click’) doesn’t fire when live(‘submit’) is bound first in IE
  • #7945 Make jQuery.param() serialize plain objects with a property named jquery correctly
  • #8033 jQuery 1.4.4+ fails to load on pages with old Prototype (<= 1.5) or Current Prototype + Scriptaculous in IE
  • #8039 Selectors with HTML5 input types not work in IE6/7
  • #8052 Update jQuery.support.noCloneEvent test to function properly in IE9
  • #8095 Properly handles the case where browser cache needs to be bypassed while server-side logic still delivers proper 304 responses. Unit test added
  • #8098 Use the fast document.head when available
  • #8099 Always restore to correct display value based on element’s expected default display
  • #8107 Fix argument handling for $.ajax for multiple method signatues and add test case
  • #8108Temporary fix for jQuery metadata being exposed on plain JS objects when serializing with JSON.stringify to avoid compatibility-breaking changes. A proper fix for this will be landed in 1.6
  • #8115 Renames all references to jXHR with jqXHR in the code (like was done in the doc)
  • #8123 The default for .clone() is to not clone any events
  • #8125 Status is set to 200 for requests with status 0 when location.protocol if “file:”. Added test/localfile.html to control it works
  • #8129 Fix cloning multiple selected options in IE8
  • #8135 Makes sure any exception thrown by Firefox when trying to access an XMLHttpRequest property when a network error occured is caught and notified as an error. Added test/networkerror.html to test the behavior
  • #8138 Access to document.location is made only once at load time and if it fails (throwing an exception in IE when document.domain is already set), we use the href of an A element instead
  • #8145 Added readyWait tests
  • #8146 introducing the xhrFields option with is a map of fieldName/fieldValue to set on the native xhr. Can be used to set withCredentials to true for cross-domain requests if needed
  • #8152 applying the same special cases for protocol “chrome-extension:” as were for “file:” (needs tests). Re-organizes and fixes the handling of special cases for HTTP status code in the xhr transport
  • #8177 XHR transport now considers 304 Not Modified responses as 200 OK if no conditional request header was provided (as per the XMLHttpRequest specification)
  • #8193 Fixes abort in prefilter. No global event will be fired in that case even if the global option is set to true. Unit test added
  • #8198 Remove unnecessary “script.type = text/javascript;”
  • #8200 Unexpose $.support._scriptEval as it’s not needed. Use a private var instead
  • #8209 Make sure that mousing over Chrome “internal div” doesn’t trigger a mouseleave
  • #8219 Introduces the mimeType option to override content-type header in conversion (and in native xhr when possible). Adds companion overrideMimeType method on jqXHR object (it simply sets the option)
  • #8220 Remove backslashes from tag name filter
  • #8245 Ajax now ensures header names are capitalized so that non-compliant xhr implementations don’t override them
  • #8250 ajax does not work in opera 10 widgets
  • #8277 Sets data to undefined rather than null when it is not provided in ajax helpers so that it won’t revent data set in ajaxSettings from being used.
  • #8297 Make sure response headers with empty values are handled properly and do not prevent proper parsing of the entire response headers string.
  • #8353 Adds a catch block in resolveWith so that the finally block gets executed in IE7 and IE6.
  • #8365 Make sure that IE 9 still clones attributes.

jQuery Conference 2011: San Francisco Bay Area Conference Announced

Posted on by

The jQuery Project is very excited to announce the dates for our next San Francisco Bay Area conference; after a fantastic event in 2010, we’ll be returning to the Microsoft Silicon Valley Research Center in Mountain View, California on April 16th and 17th, 2011.

The San Francisco Bay Area conference is the first of two events planned by the jQuery Project in 2011. We’re also in the early stages of planning an event for the East Coast for later this year (we’ll post details as they become available).

Registration is now open! Regularly priced tickets are $299, and for a limited time, there are early-bird tickets available at a $50 discount (early-bird tickets available until March 2nd, or while supplies last).

For more details on the what, when and who, head over to the events site.

In addition to two days of jQuery sessions, we’ll once again be offering a day of jQuery training, on the Friday before the conference. In response to popular demand last year, we’ll be offering two training tracks — Beginner jQuery and Advanced. The training is generoursly offered by our friends at JupiterIT and Bocoup, and all proceeds go directly to funding the future growth of the jQuery project. Keep an eye on this blog and the events site for specific training agendas, coming soon.

Want to contribute?

Interested in speaking? We’re still filling out the roster, and we’d love to have you! Our Call for Papers is live here, and submissions are already starting to roll in. Keep an eye on the jQuery Blog for agenda updates as we fill the slots.

Lastly, if you or your company would like to help out by sponsoring the event, send an email to sponsorship@jquery.com. Every little bit helps, and we’d love to work with you and your team!

That’s it for now folks — looking forward to seeing you all in sunny California!

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

If you weren’t able to attend the jQuery Conference in Boston last year (with speakers such as John Resig and Karl Swedberg in attendance) we’ve got some great news – almost all of the talks are now available to watch online (either on your desktop or mobile device) via our conference site. You can also pick-up the slides mentioned in the videos by clicking on any individual speaker’s talk.

 

Upcoming jQuery Training Events

Group training can be an excellent way to improve your jQuery skills and Ben Alman over at Bocoup (a jQuery sponsor) would like to make a special announcement about upcoming events they’ll be holding in March and July.

Bocoup currently has two 3-Day Comprehensive jQuery Training sessions scheduled. As always, sessions will be held at The Bocoup Loft in Boston, and 10% of profits will go directly to the jQuery Foundation. Be sure to sign up now, since class sizes are limited to twelve people. Read more about our curriculum and trainers here:

March 2nd – 4th, 2011 and July 13th – 15th, 2011

jQuery Team member Karl Swedberg will also be holding a hands-on training event between March 1st-3rd in Holland, Michigan.

Karl will painlessly walk you through jQuery’s principles and show you how to make use of the library in your everyday coding. Karl will also be giving away free copies of his Learning jQuery book to all attendees.

For more information or to register, check out the IdeaFoundry site.

 

A New Episode Of YayQuery

For fans of the YayQuery podcast, Paul Irish (jQuery core team), Adam Sontag (jQuery UI team) and community members Alex Sexton and Rebecca Murphey are back with a new episode of their video podcast. In their latest episode, they discuss the new Deferreds features with one of the main developers behind the Ajax re-write (Julian Aubourg) and also look at other new developments in the world of jQuery and JavaScript.

Watch or listen to the podcast at YayQuery.com.

And that’s it!. If you have any interesting jQuery articles or posts which you think would be beneficial for the community to read, please feel free to mention them in the comments. We’ll be back with another Community Update in a few weeks with more news on the next version of jQuery.

Until then, good luck with all your projects!.
