jQuery Color 2.1.0

Posted on by

Early last week I released jQuery Color 2.0.0, the wait for a jQuery Color plugin that gives you an API to work with colors is over.

What’s new in jQuery Color 2.0.0?

jQuery Color has faithfully supported animating colors between two hex values since the beginning. Many developers asked for access to the internal functions we had declared to make it all possible. Version 2 now includes an API to create and modify colors, as well as support for RGBA & HSLA colors and animations.

You can read more about the API and features on the repository readme.

Any issues should be reported on the issue tracker.

Why jQuery Color 2.1.0 already?

It’s every developers dream to land a major version perfectly on the first release, but it is rarely achieved. In the last two weeks a few minor bugs that were left in 2.0.0 have been fixed, and a new function was added to the API which should help support SVG style properties.

Download jQuery Color 2.1.0

You can download the release from our CDN provided by Media Temple.

In order to save on file size, the jQuery Color plugin only supports the Basic color keywords by default, the Extended Color Keywords are included in a separate file. If you want to include both, you can also download the bundled version.

jQuery 1.8 box-sizing: width(), css(“width”), and outerWidth()

Posted on by

One of the great new features in jQuery 1.8 is a built-in understanding of box-sizing: border-box which is supported by every modern browser. (Sorry, IE6 and IE7, please take one step back; I said modern browser.)

If you showed people an element with a border on the screen and asked them the width of that element, they would naturally measure from the outside edges of the border. Yet that’s not the way CSS works in its default content-box mode. Normally, CSS width and height only include the “content” inside the border and padding. As a result, designers (and jQuery) often need to add the width to the right/left padding and border to get the “natural” width of the element.

Using box-sizing: border-box changes the CSS notion of the width of an element to include both the padding and the border dimensions, just the way you’d naturally measure it. jQuery versions before 1.8 were not fully trained in the ways of the border-box, but we’ve fixed this bug.

One thing that hasn’t changed is the return value of the .width() method. As it’s always been documented, it gets and/or sets the “content” width of an element, and that is regardless of the CSS box-sizing being used by the element. However, jQuery 1.8 now needs to check the box-sizing property whenever you use .width() so that it can decide whether it needs to subtract out the padding and border width. That can be expensive—up to 100 times more expensive on Chrome! Fortunately, most code doesn’t use .width() enough times for this to be noticeable, but code that gets the width of dozens of elements at once could be impacted.

There is a very easy way to avoid this performance penalty if it does impact your code. Simply use .css("width") instead of .width() to make it clear you want to get or set the actual width of the element as specified by the CSS. That doesn’t require jQuery to look at box-sizing. Remember, however, that .css("width") as a getter returns a string with “px” at the end, so you’ll want to use something like parseFloat( $(element).css("width") ) for situations where the result must be numeric.

And of course, everything mentioned here about .width() also applies to .height() as well; use .css("height") to skirt the performance penalty there.

Using .outerWidth() as a setter

In other dimensionally related news, jQuery’s .outerWidth() and .outerHeight() methods have been updated in 1.8 so that they can be used as setters. (jQuery UI has supported them as setters since UI version 1.8.4, but now it’s built into core.) To use .outerWidth() as a setter, pass an argument that is a number representing the outer width (CSS “content” width, plus padding and border width). And yes, this handles the box-sizing: border-box situation fine as well; it’s basically the same as setting the .css("width") in that case.

We’ve received a few reports from people who had problems with .outerWidth() in jQuery 1.8 because it was returning the jQuery object instead of a numeric width. This happens if you call $(element).outerWidth(0) for example. Before jQuery 1.8, this was an invalid use of the API because it was documented to accept a single Boolean argument. However, it treated the invalid argument as a Boolean and returned the width. In 1.8, jQuery uses the value 0 to set the width, and like most setters it returns the jQuery object.

We’re in the process of updating the API documentation for all the changes to 1.8, but for now you can refer back to the changelog in the jQuery 1.8 announcement to see what’s changed.

jQuery 1.8 RC1 Released

Posted on by

jQuery 1.8RC1 is here. Yep, RC as in Release Candidate. The good news is that this release is a few days later than I expected it to be. It’s good news because we received several valuable but last-minute bug reports we were able to fix. Many thanks to those of you who took the time to try out Beta 2 with your code, and especially to those who found and reported bugs.

Now I know there are a lot of you out there thinking, “Gee whiz, nobody ever lets me find bugs.” Well, here’s your chance to be a hero to the jQuery community. In this Release Candidate we may have taken some working features and inserted problems so obscure that even we don’t know where they are. Please find them! Just grab the code from here:

http://code.jquery.com/jquery-1.8rc1.js

Try out this Release Candidate code wherever you use jQuery, and let us know about any issues you find via the bug tracker. Be sure to mention you’re testing against jQuery 1.8 RC1, and please create a test case that shows the bug using jsFiddle.net so we can reproduce it and investigate. You can use the “jQuery (edge)” choice for framework in jsFiddle, which represents the most up-to-date code.

Oh, and did I mention this is a Release Candidate? Yeah, I did. Who knows if there will ever be a jQuery 1.8.1? If you find a bug after we release jQuery 1.8, it could be six months before it’s fixed. Six months of misery, all because you didn’t test the Release Candidate! One and a half women could make a baby while you’re waiting for that critical bug fix! For your own sake, please try it out!

jQuery 1.8 Beta 2 Released

Posted on by

It’s been a crazy few weeks around jQuery Central, what with the release of Beta 1 and the jQuery Conference in San Francisco following that. Fear not! Between all the travel, conferences, meetings, and blog posts about the future of jQuery, we’ve actually managed to write some more code. As proof, here is jQuery 1.8 Beta 2:

http://code.jquery.com/jquery-1.8b2.js

This is the critical section in the program where we call on you, the jQuery community, to help us bring this one home. Use Beta 2 with old browsers, new browsers, red browsers and blue browsers. (That’s IE6, Chrome Canary, Opera, and Internet Explorer, respectively.) Test this file with all your code, please test it well in every mode. Did something break in Beta 2? Please tell us now before we’re through!

With assistance from those of you who tested Beta 1, we found a few bugs and squashed them. We can’t emphasize enough how important it is for us to get feedback from you as you test with these beta versions. We don’t like releasing final versions that cause problems when you drop them into your web pages, and the way to prevent that is to test with the beta and let us know about problems in advance.

NOTE: This release required coordination with jQuery UI to fix a few problems. For that reason, pages using jQuery UI will need to include the latest UI master version to test against jQuery 1.8b2. You can get it here: http://code.jquery.com/ui/jquery-ui-git.js. There will be a maintenance release of jQuery UI 1.8 that includes jQuery core 1.8 support, but users are encouraged to update to jQuery UI 1.9 when it is released.

If you find a problem, please try to reduce it to a simple test case. jsFiddle is our preferred way to get test cases, since it allows us to tweak the test case, diagnose the problem, and explore solutions. (Select jQuery (edge) for the framework, which is the latest code.) With test case in hand, head over to the bug tracker and let us know what happened. Thanks!

In addition to bug fixes reported in Beta 1, this new beta also has a significant rewrite of the Sizzle engine for even better performance. It fixes a big pile of bugs related to IE 6, 7, and 8 and makes those browsers more consistent to use. Perfection with oldIE will always be an elusive thing, but we’re still trying to make your development life as easy as possible no matter the browser.

If you build your own custom versions as described in the README file on Github, you now have the option of leaving out some of the deprecated functionality that will be removed in future versions. We’ll be adding to this file as we isolate additional deprecated functionality.

Below is a complete list of the changes since jQuery 1.7.2.

Just Added: Training at SF jQuery Conference!

Posted on by

In response to the flood of requests and emails, and our original promise to work on this, we’ve got an announcement: we’ve added a single day Beginner/Intermediate training right before the San Francisco jQuery Conference :)

Tickets are on sale now (left side, below the fold). The training will be provided by our friends at Bocoup, and hosted by the ever-generous folks at Microsoft. Here’s a snippet of what Trainers Ben Alman and Rebecca Murphey will be covering:

At Bocoup’s intermediate one-day jQuery training, you’ll work with jQuery veterans to build a foundation that will make you a stronger developer and get you prepared for all the great talks that you’ll see over the next two days. You’ll even learn the basics of creating your own jQuery plugin. Topics that will be covered include:

  • The jQuery() function
  • Selecting & Traversing
  • Manipulating the DOM
  • Making stuff happen with Events
  • AJAX
  • Enhancing with Effects
  • Extending jQuery with Plugins
  • jQuery UI
  • jQuery Mobile

To note: the training and conference are both in San Francisco, but take place in different locations. The training is in the heart of San Fran on Market Street, and the conference is about five to ten minutes from there, on the UCSF Mission Bay campus. Please also note that the conference and training require separate admission tickets, so make sure you’ve purchased both if you’d like to attend both.

We’re still working on the possibility of adding an Advanced training, but thus far have had mostly requests for beginner materials. So here that is :)

Hope you’ve all bought your tickets to the conference; can’t wait to see you there!

Getting Touchy About Patents

Posted on by

Touch events have become a hot topic for web developers as more and more companies move into the mobile space. Most of us know that touch events support single and multi-touch tracking. Some of us know the trickiness of working with touch and mouse at the same time. Fewer know that there are multiple touch event models, and even fewer have tried to support multiple models at the same time. I’d like to talk about where we are today, how we got here, and the potential problems we may face in the future.

A Brief History

Back in 2007, Apple introduced the iPhone, and with it came touch events. Neil Roberts sums up the Apple implementation well in a SitePen article: “Though at first the APIs seem a little sketchy, once you’ve learned them you should be able to do amazing things in your application.” Sure enough, we’ve seen plenty of amazing things, without too much complaint of the “sketchy” API. This model was later implemented by Android, Nokia, RIM, Opera, and others. Apple’s implementation is still only available in their private fork of WebKit; it wasn’t until the end of 2009 that touch events first appeared in the main WebKit repo, coming from the Android implementation.

Also in 2009, the W3C started discussing a unified pointer model for DOM Level 3 Events. The idea was that touch (including multi-touch), pen/stylus, and mouse events would be coalesced into a single model, making it easy to support all pointer types at once. However, this was abandoned because the goal at the time was to keep the spec as small as possible in order to become a recommendation faster.

Another two years later (March 2011), Mozilla released Firefox 4, featuring their own flavor of touch events. The Mozilla model is much closer to the mouse event model and the abandoned W3C model in that the event objects are flat; properties such as `event.pageX` exist and there is no touch list. If you want to track multiple touches, you can do so via the event’s `streamId`. Mozilla later deprecated this implementation in favor of an emerging W3C spec based on Apple’s model.

In January 2011, the W3C started drafting a Touch Events spec based on the WebKit implementation. A few months later, it became a Working Draft, and in December it became a Candidate Recommendation. The next month, a Patent Advisory Group (PAG) was formed in order to investigate patents disclosed by Apple. Apple’s absence from the Touch Events Working Group (WG) and their patent disclosure has caused the W3C to stop work on the spec and they do not plan to continue until the PAG has concluded and/or makes a recommendation to the WG. As of this writing, the PAG has not made a decision about the impact of the patents, but the group’s goal is to reach a speedy conclusion.

Meanwhile, Microsoft took a different approach to touch and has implemented their own pointer events in IE10 with the MSPointerEvent object. The MSPointerEvent object is similar to the original Mozilla implementation, in that the event objects are flat and contain a `pointerId` property. However, there are some important differences between MSPointer and all of the other models, which are touch-specific.

Note: The above is just a brief history of touch events on the Web; if you’re interested in the history of touch interfaces, you might want to check out Bill Buxton’s Multi-Touch Systems that I Have Known and Loved.

Pointer Events vs. Touch Events

As mentioned above, generic pointer events such as the original W3C idea or MSPointer, have the benefit of supporting multiple pointer devices. In fact, with a Samsung tablet running Windows 8, mouse, pen, and fingers are all normalized to MSPointer; you can even use the `pointerType` property to determine which type of pointer is being used. In addition to supporting all current pointer devices, MSPointer is designed in such a way that future devices can easily be added, and existing code will automatically support the new device. Even better, MSPointer event objects have the same structure as other events, reducing the learning curve compared to the conglomerate of TouchEvent, TouchList, and Touch.

Another big difference between MSPointer and Touch is that MSPointer has support for hovering (over and out events). While most touch devices have a hardware limitation that doesn’t allow for hovering, Sony recently announced the Xperia sola with “magical floating touch technology.” This brings up an important issue: Touch Events were designed based on a specific device for a specific type of input. Pointer Events represent a completely different approach to input on the Web. While we’ve already covered how this impacts developers, it’s interesting to consider the impact on hardware manufacturers. In order for Apple to succeed with touch interfaces, they had to create a new event model. Innovation for new form factors and new input methods will either be stifled by the existing standards or will require a new set of APIs, following in Apple’s footsteps with the iPhone and Touch Events. Pointer Events provides a clean solution not only for developers, but for hardware manufacturers as well. It’s conceivable that in a few years developers could use Pointer Events as the only event model for pointers, leaving Mouse Events as a thing of the past.

A Splintered Future

Although the W3C is still planning to move forward with the Touch Events spec (pending a recommendation from the PAG), the future is unclear. Even if the PAG determines that Apple’s patents don’t apply and the spec becomes a W3C Recommendation, it’s not clear that Microsoft would implement such a model given the need for a multi-input event system in Windows. If the W3C were to change directions and start a Pointer Events spec, it’s not clear that Apple, or more broadly WebKit, would implement the new event model. It’s entirely possible that even with a W3C Recommendation, we’ll be stuck for years without a consistent event model across browsers and devices.

Regardless of which model the W3C chooses to pursue, jQuery is dedicated to filling in the gaps, just like we do for other events such as submit and change. We think the pointer event model is easier to use and more future-proof, and we hope that it can be standardized, even if Touch Events are standardized as well. However, we are only interested in normalizing to a W3C Recommendation, and will not provide custom pointer events if there is no official W3C specification. We’re working with the W3C and Microsoft to try to find the best way forward for our users and the Open Web.

Call to Action: Microsoft to Submit Pointer Event Proposal

We would like to publicly call upon Microsoft to submit a proposal to the W3C for Pointer Events. The Touch Events Working Group, and by extension various browser vendors, have stated interest in pointer events. The most effective way to proceed would be for Microsoft to officially submit a proposal to the W3C.

Call to Action: Community to Experiment with Both Event Models

We would also encourage the community to experiment with Touch and MSPointer. Play with the APIs, build apps, and provide feedback. If you’re interested in this, but don’t have the necessary hardware, consider pairing up with one or more local developers who do. While there are a lot of developers building on top of Touch, there are very few people building on top of MSPointer, and even fewer publicly comparing them. We encourage you to send your feedback directly to the W3C public-webevents mailing list, but feel free to leave feedback here and we will pass it along.

Call to Action: Submit Prior Art

If you know of any prior art for multi-touch/touch lists, even outside of the Web, please get in touch with the W3C. This includes programming models and APIs, especially those using events. This will help the Patent Advisory Group come to a conclusion sooner. Again, if you’d rather leave comments here, we will pass them along.

jQuery 1.7.2 Released

jQuery 1.7.2 is looking good! The release candidate went smoothly so we’ve made only one small change and are releasing it to your eager hands today. You can get the oven-fresh code from the jQuery CDN now, with Google and Microsoft CDNs soon to follow:

Note: If you’re using jQuery Mobile, please use jQuery 1.7.2 only with jQuery Mobile 1.1. For previous versions of jQuery Mobile, stay with jQuery core 1.7.1 or earlier.

You can use the bug tracker to report bugs; be sure to create a test case on jsFiddle so we can figure it out easily. If you’re not sure it’s a bug, ask on our forum or on StackOverflow. Please don’t use the blog comments below to report bugs.

As always, this release wouldn’t have been possible without the hard work of many people. First, the jQuery Core Team: gnarf, jaubourg, mikesherov, rwldrn, and timmywil. The support of the jQuery UI, Mobile, and Infrastructure teams was greatly appreciated as well, especially danheberden’s valiant struggle against Trac.

Community members like adebree, caii, cmc3cn, KYSergey, mathiasbynens, miskith, MrMamen, Orkel, pasky, SineSwiper, tavelli, and vlazar pitched in by reporting, verifying, and fixing bugs. Special jQuery Gold Leaf Cluster thanks to gibson042 and sindresorhus for their work in making 1.7.2 a great release. Don’t let these people have all the fun! If you’d like to contribute to the web’s most popular Javascript library, hop onto #jquery-dev on IRC or the Developing jQuery Core section on our forum and say hello!

Many thanks to Louis-Rémi Babé, who submitted a patch to fix a regression with negative margin animations a mere 30 minutes before the release!

jQuery 1.7.2 RC1 Released

Posted on by

jQuery 1.7.2 will be arriving soon! To make sure that we’ve fixed the bugs voted “Most Likely to Annoy” without introducing any new bugs, we need your help in testing this release candidate. You can get the code from the jQuery CDN:

It will only take a few minutes to drop in this latest file and test it with your code. If you’ve got a lot of pages, the list of fixed bugs below may be a helpful guide for determining what to test. And of course, if you reported a bug or were affected by one listed below, please re-test to be sure we fixed it for good. We’ve tested it internally against the current builds of jQuery UI and jQuery Mobile. There is one compatibility issue with jQuery Mobile 1.1 RC1 that has already been fixed and will be addressed by their next release.

Looking for an even easier way to test your web site with the latest jQuery? On Windows you can use the excellent Fiddler tool and create an AutoResponder rule to point your HTTP script requests for jQuery to the file location above. Then you are testing your live web site with the latest jQuery on your PC, without having to edit any files at all! If you know of similar tools for other platforms, leave a message in the comments below.

If you are particularly interested in IE6 support, please help us out. We are having sporadic trouble running the unit tests in IE6. It hasn’t been possible for us to determine the cause of these problems, but the problem doesn’t happen consistently and the sheer size of our test suite may just be overwhelming a browser that is more than a decade old. If you observe any reproducible failures in real code, please let us know and try to provide the smallest possible test case.

You can use the bug tracker to report bugs; be sure to create a test case on jsFiddle so we can figure it out easily. If you’re not sure it’s a bug, ask on our forum or on StackOverflow. Please don’t use the blog comments below to report bugs.

Announcing the jQuery Foundation

Posted on by

(BOSTON) — The jQuery Board, in conjunction with Software Freedom Conservancy, is proud to announce the formation of the jQuery Foundation, Inc., an independent organization that will manage jQuery, the Internet’s number one JavaScript library, and its constituent projects.

The jQuery Board previously administered jQuery under the aegis of the Conservancy, a public charity that acts as a non-profit home for free software projects.

The new jQuery Foundation is a non-profit trade association dedicated to supporting development of the jQuery Core, UI, and Mobile projects; providing jQuery documentation and support; and fostering the jQuery community.

Dave Methvin, who recently took over as the head of the jQuery Core development team, will also serve as the Foundation’s President. “jQuery is the most popular JavaScript library, and creating an autonomous organization is the next step in ensuring its future development and benefiting everyone who uses jQuery,” said Methvin. “We’ll be announcing several initiatives shortly, including the next jQuery Conference and other efforts driven by needs within the community and the project.”

“I’m extremely excited to see the jQuery Foundation springing to life. I’m glad that Dave Methvin is leading the foundation and the direction of the core library. He’s a good friend and exceedingly capable of moving jQuery forward,” said John Resig, who created the library in 2005. “Meanwhile, I’ve been spending more time focusing on improving the state of JavaScript and programming education at Khan Academy. I’m psyched to be a part of the jQuery core team and Foundation and can’t wait to see how jQuery grows in the upcoming years.”

“We are proud that the jQuery Board has built jQuery into a vibrant and successful Open Source community under Conservancy’s mentorship,” said Bradley Kuhn, Executive Director of the Software Freedom Conservancy. “Our mission includes helping member projects determine whether to form their own organization, and we’re pleased jQuery is the first Conservancy project to take that step.”

The jQuery Foundation would like to thank Joel G. Kinney of Fort Point Legal, whose generous pro-bono counsel has been invaluable in transitioning to an independent organization. The Foundation is also proud to accept an honorary first donation from the Linux Fund, which has chosen to continue its tradition of supporting the open source community with a contribution to the Foundation’s inaugural operating expense budget.

About jQuery
Created in 2005 by John Resig as a JavaScript library to provide an intuitive approach for working with the DOM and Ajax, jQuery has steadily gained popularity among the development community and is the most widely-adopted JavaScript library in use today.

About the jQuery Foundation
The jQuery Foundation is a non-profit trade association and the home of jQuery, the Internet’s number one JavaScript library.  Founded by a group of leading JavaScript developers and architects, the jQuery Foundation is dedicated to three goals:  supporting development of the jQuery Core, UI, and Mobile projects; providing jQuery documentation and support; and fostering the jQuery community.

jQuery Foundation, Inc. is a Delaware non-profit currently seeking IRS 501(c)(6) status.  Donations to the jQuery Foundation will be used to further the goals of the Foundation.  For more information, visit http://jquery.org.

About Software Freedom Conservancy
Software Freedom Conservancy is a non-profit organization that helps promote, improve, develop and defend Free, Libre and Open Source software projects.  Conservancy is a home to twenty-eight software projects, each supported by a dedicated community of volunteers, developers, and users.  Conservancy’s projects include some of the most widely used software systems in the world across many application areas, including educational software deployed in schools around the globe, embedded software systems deployed in most consumer electronic devices, distributed version control developer tools, integrated library services systems, and widely used graphics and art programs.  A full list of Conservancy’s projects can be found at http://sfconservancy.org/members/current/.  Conservancy provides to these projects the necessary infrastructure and not-for-profit support services to enable the project’s communities to focus on what they do best: creating innovative software and advancing computing for the public’s benefit.

jQuery 1.7.2 Beta 1 Released

Posted on by

Hey there Internets, it’s the jQuery Core team! We haven’t talked in a while, but over the holidays we were busy fixing the bugs you reported. The result of that hard work is jQuery 1.7.2 Beta 1. We decided to get a beta out by Groundhog Day so you wouldn’t be in the shadow of six more weeks of unfixed bugs.

You can get the code from the jQuery CDN:

Oh, we know what you’re thinking: “Cool, a new version of jQuery; I’ll wait until the final release has been out a few weeks and then I’ll give it a try.” Right, and then you’ll find some bug that keeps you from upgrading. Nothing makes us sadder than finishing up a release and only then seeing a report of a serious bug that could have been fixed earlier.

So please, come out of your burrow and try this beta with your code. Did we miss an old bug? Did we create a new bug that makes you feel like Bill Murray waking up to “I Got You Babe?” We want to know. You can use the bug tracker to report bugs; be sure to create a test case on jsFiddle so we can figure it out easily. If you’re not sure it’s a bug, ask on our forum or on StackOverflow.
