jQuery 3.1.0 Released – No More Silent Errors

Posted on by

Not so long ago, we released jQuery 3.0. One of the major features of jQuery 3.0 was a small rewrite of jQuery Deferreds. Specifically, we made them compatible with the Promises/A+ spec. That basically meant that errors had to be silenced and passed as rejection values to rejection handlers (added using deferred.catch()). This had the advantage of preventing Promise handlers from getting blocked up by runtime errors, but the disadvantage of errors being silenced if no rejection handlers were added. While this was the right move for Deferreds, we had also changed jQuery.ready and jQuery.fn.ready to use the new spec-compliant Deferreds under the covers.

Unfortunately, if you were using the usual ways to attach ready handlers (e.g. jQuery(function() {}) and jQuery(document).ready(function() {})), you had no way to add a rejection handler. Plus, it wasn’t obvious that you were in Deferred land. Any runtime exceptions were getting swallowed and lost in space. I think they ended up somewhere near Pluto, which isn’t even a planet anymore! There were workarounds, but this wasn’t acceptable to us.

We immediately set out to fix this, and thus jQuery 3.1.0 was born. No longer will errors be silent! You will see them logged to the console by default. If you’d like to have more control on how these errors are handled, we also added an entry point: jQuery.readyException. In most cases, you won’t need to use it, but any errors that are thrown within a ready handler will get passed to this function should you need it.

jQuery.readyException = function(error) {
  // "error" is thrown from any ready handler
};

The default jQuery.readyException will re-throw the error asynchronously, to avoid stopping execution and log the error to the console. We hope this solves any debugging issues you may have experienced when using jQuery 3.0.

We do not expect this release to have any breaking changes, but if you do encounter bugs in upgrading from the previous version, please let us know.

If you’d like help upgrading from jQuery 1.x or 2.x to jQuery 3.0, please check out the 3.0 Upgrade Guide and the jQuery Migrate 1.4.1 blog post.

jQuery 3.0 Final Released!

Posted on by

jQuery 3.0 is now released! This version has been in the works since October 2014. We set out to create a slimmer, faster version of jQuery (with backwards compatibility in mind). We’ve removed all of the old IE workarounds and taken advantage of some of the more modern web APIs where it made sense. It is a continuation of the 2.x branch, but with a few breaking changes that we felt were long overdue. While the 1.12 and 2.2 branches will continue to receive critical support patches for a time, they will not get any new features or major revisions. jQuery 3.0 is the future of jQuery. If you need IE6-8 support, you can continue to use the latest 1.12 release.

Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few “breaking changes” that justified the major version bump, but we’re hopeful the breakage doesn’t actually affect that many people.

To assist with upgrading, we have a brand new 3.0 Upgrade Guide. And the jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code. Your feedback on the changes will help us greatly, so please try it out on your existing code and plugins!

You can get the files from the jQuery CDN, or link to them directly:

https://code.jquery.com/jquery-3.0.0.js

https://code.jquery.com/jquery-3.0.0.min.js

You can also get the release from npm:

npm install [email protected]

In addition, we’ve got the release for jQuery Migrate 3.0. We highly recommend using this to address any issues with breaking changes in jQuery 3.0. You can get those files here:

https://code.jquery.com/jquery-migrate-3.0.0.js

https://code.jquery.com/jquery-migrate-3.0.0.min.js

npm install [email protected]

Slim build

Finally, we’ve added something new to this release. Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code. The size of jQuery is very rarely a load performance concern these days, but the slim build is about 6k gzipped bytes smaller than the regular version – 23.6k vs 30k. These files are also available in the npm package and on the CDN:

https://code.jquery.com/jquery-3.0.0.slim.js

This build was created with our custom build API, which allows you to exclude or include any modules you like. For more information, have a look at the jQuery README.
 

Compatibility with jQuery UI and jQuery Mobile

While most things will work, there are a few issues that jQuery UI and jQuery Mobile will be addressing in upcoming releases. If you find an issue, keep in mind that it may already be addressed upstream and using the jQuery Migrate 3.0 plugin should fix it. Expect releases soon.

 

Major changes

Below are just the highlights of the major new features, improvements, and bug fixes in these releases, you can dig into more detail on the 3.0 Upgrade Guide. A complete list of issues fixed is available on our GitHub bug tracker. If you read the blog post for 3.0.0-rc1, the below features are the same.

jQuery.Deferred is now Promises/A+ compatible

jQuery.Deferred objects have been updated for compatibility with Promises/A+ and ES2015 Promises, verified with the Promises/A+ Compliance Test Suite. This meant we needed some major changes to the .then() method. Legacy behavior can be restored by replacing any use of .then() with the now-deprecated .pipe() method (which has an identical signature).

  1. An exception thrown in a .then() callback now becomes a rejection value. Previously, exceptions bubbled all the way up, aborting callback execution. Any deferreds relying on the resolution of the deferred that threw an exception would never have resolved.

  2. Example: uncaught exceptions vs. rejection values

    
    var deferred = jQuery.Deferred();
    deferred.then(function() {
      console.log("first callback");
      throw new Error("error in callback");
    })
    .then(function() {
      console.log("second callback");
    }, function(err) {
      console.log("rejection callback", err instanceof Error);
    });
    deferred.resolve();
    

    Previously, “first callback” was logged and the error was thrown. All execution was stopped. Neither “second callback” nor “rejection callback” would have been logged. The new, standards-compliant behavior is that you’ll now see “rejection callback” and true logged. err is the rejection value from the first callback.


  3. The resolution state of a Deferred created by .then() is now controlled by its callbacks—exceptions become rejection values and non-thenable returns become fulfillment values. Previously, returns from rejection handlers became rejection values.

  4. Example: returns from rejection callbacks

    
    var deferred = jQuery.Deferred();
    deferred.then(null, function(value) {
      console.log("rejection callback 1", value);
      return "value2";
    })
    .then(function(value) {
      console.log("success callback 2", value);
      throw new Error("exception value");
    }, function(value) {
      console.log("rejection callback 2", value);
    })
    .then(null, function(value) {
      console.log("rejection callback 3", value);
    });
    deferred.reject("value1");
    

    Previously, this would log “rejection callback 1 value1”, “rejection callback 2 value2”, and “rejection callback 3 undefined”.

    The new, standards-compliant behavior is that this will log “rejection callback 1 value1”, “success callback 2 value2″, and “rejection callback 3 [object Error]”.


  5. Callbacks are always invoked asynchronously, even if a Deferred has already been resolved. Previously, these callbacks were executed synchronously upon binding.

  6. Example: async vs sync

    
    var deferred = jQuery.Deferred();
    deferred.resolve();
    deferred.then(function() {
      console.log("success callback");
    });
    console.log("after binding");
    

    Previously, this would log “success callback” then “after binding”. Now, it will log “after binding” and then “success callback”.


Important: while caught exceptions had advantages for in-browser debugging, it is far more declarative (i.e. explicit) to handle them with rejection callbacks. Keep in mind that this places the responsibility on you to always add at least one rejection callback when working with promises. Otherwise, some errors might go unnoticed.

We’ve built a plugin to help in debugging Promises/A+ compatible Deferreds. If you are not seeing enough information about an error on the console to determine its source, check out the jQuery Deferred Reporter Plugin.

jQuery.when has also been updated to accept any thenable object, which includes native Promise objects.

https://github.com/jquery/jquery/issues/1722
https://github.com/jquery/jquery/issues/2102

Added .catch() to Deferreds

The catch() method was added to promise objects as an alias for .then(null, fn).

https://github.com/jquery/jquery/issues/2102

Error cases don’t silently fail

Perhaps in a profound moment you’ve wondered, “What is the offset of a window?” Then you probably realized that is a crazy question – how can a window even have an offset?

In the past, jQuery has sometimes tried to make cases like this return something rather than having them throw errors. In this particular case of asking for the offset of a window, the answer up to now has been { top: 0, left: 0 } With jQuery 3.0, such cases will throw errors so that crazy requests aren’t silently ignored. Please try out this release and see if there is any code out there depending on jQuery to mask problems with invalid inputs.

https://github.com/jquery/jquery/issues/1784

Removed deprecated event aliases

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

https://github.com/jquery/jquery/issues/2286

Animations now use requestAnimationFrame

On platforms that support the requestAnimationFrame API, which is pretty much everywhere but IE9 and Android<4.4, jQuery will now use that API when performing animations. This should result in animations that are smoother and use less CPU time – and save battery as well on mobile devices.

jQuery tried using requestAnimationFrame a few years back but there were serious compatibility issues with existing code so we had to back it out. We think we’ve beaten most of those issues by suspending animations while a browser tab is out of view. Still, any code that depends on animations to always run in nearly real-time is making an unrealistic assumption.

Massive speedups for some jQuery custom selectors

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

This change actually made it into 1.12/2.2, but we wanted to reiterate it for jQuery 3.0.

https://github.com/jquery/jquery/issues/2042

As mentioned above, the Upgrade Guide is now available for anyone ready to try out this release. Aside from being helpful in upgrading, it also lists more of the notable changes.

jQuery 3.0 Release Candidate…Released!

Posted on by

Welcome to the Release Candidate for jQuery 3.0! This is the same code we expect to release as the final version of jQuery 3.0 (pending any major bugs or regressions). When released, jQuery 3.0 will become the only version of jQuery. The 1.12 and 2.2 branches will continue to receive critical support patches for a while, but will not get any new features or major revisions. Note that jQuery 3.0 will not support IE6-8. If you need IE6-8 support, you can continue to use the latest 1.12 release.

Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few “breaking changes” that justified the major version bump, but we’re hopeful the breakage doesn’t actually affect that many people.

To assist with upgrading, we have a brand new 3.0 Upgrade Guide. And the jQuery Migrate 3.0-rc plugin will help you to identify compatibility issues in your code. Your feedback on the changes will help us greatly, so please try it out on your existing code and plugins!

Major changes

Below are just the highlights of the major new features, improvements, and bug fixes in these releases, you can dig into more detail on the 3.0 Upgrade Guide. A complete list of issues fixed is available on our GitHub bug tracker.

jQuery.Deferred is now Promises/A+ compatible

jQuery.Deferred objects have been updated for compatibility with Promises/A+ and ES2015 Promises, verified with the Promises/A+ Compliance Test Suite. This meant we needed some major changes to the .then() method:

  • An exception thrown in a .then() callback now becomes a rejection value. Previously, exceptions bubbled all the way up, aborting callback execution and irreversibly locking both the parent and child Deferred objects.
  • The resolution state of a Deferred created by .then() is now controlled by its callbacks—exceptions become rejection values and non-thenable returns become fulfillment values. Previously, returns from rejection handlers became rejection values.
  • Callbacks are always invoked asynchronously. Previously, they would be called immediately upon binding or resolution, whichever came last.

Consider the following, in which a parent Deferred is rejected and a child callback generates an exception:


var parent = jQuery.Deferred();
var child = parent.then( null, function() {
  return "bar";
});
var callback = function( state ) {
  return function( value ) {
    console.log( state, value );
    throw new Error( "baz" );
  };
};
var grandchildren = [
  child.then( callback( "fulfilled" ), callback( "rejected" ) ),
  child.then( callback( "fulfilled" ), callback( "rejected" ) )
];
parent.reject( "foo" );
console.log( "parent resolved" );

As of jQuery 3.0, this will log “parent resolved” before invoking any callback, each child callback will then log “fulfilled bar”, and the grandchildren will be rejected with Error “baz”. In previous versions, this would log “rejected bar” (the child Deferred having been rejected instead of fulfilled) once and then immediately terminate with uncaught Error “baz” (“parent resolved” not being logged and the grandchildren remaining unresolved).

While caught exceptions had advantages for in-browser debugging, it is far more declarative (i.e. explicit) to handle them with rejection callbacks. Keep in mind that this places the responsibility on you to always add at least one rejection callback when working with promises. Otherwise, any errors will go unnoticed.

jQuery 1.12.4 and 2.2.4 Released

Posted on by

jQuery 1.12.4 and 2.2.4 have been released! These are small releases with a couple bug fixes. We fixed a sticky issue for those using the AMD source and a “:visible” selector bug in 1.12.3.

If you need any help upgrading, check out the newest release of the jQuery Migrate plugin. Note that jQuery Migrate 1.4.1 is meant to work with these 1.x and 2.x releases, and not jQuery 3.0. jQuery 3.0 has not been released yet – though we will have an RC for you very soon – but another version of Migrate will be released for jQuery 3.0.

We do not expect this release to have any breaking changes, but if you do encounter bugs in upgrading from the previous version, please let us know.

jQuery 1.12.1 and 2.2.1 Released

Posted on by

As the jQuery team prepares for a 3.0 final release, we continue to maintain the 1.12 and 2.2 branches. These two patch releases fix a few bugs and improve stability. The most significant bug fix involved a problem with the .position() method, which affected how jQuery UI tooltips were positioned in Internet Explorer.

We do not expect this release to have any breaking changes, but if you do encounter bugs in upgrading from the previous version, please let us know.

jQuery 3.0 Beta Released

Posted on by

The time has come. On this day, the 10th anniversary of jQuery, jQuery 3.0 has reached beta status. Last week, we announced the last minor releases to the 1.x and 2.x branches. Those branches will continue to receive patches for a limited time (i.e. only major regressions or bugs); jQuery 3.0 is the future. If you need IE6-8 support, you can continue to use the latest 1.12 release.

The Death of jQuery Compat

only-one

If you read the jQuery 3.0 alpha blog post, you might remember that we announced something we called “jQuery Compat”. You can forget that. On January 12, Microsoft dropped support for IE8, IE9, and IE10. We’re not going to go that far just yet, but we are dropping support for IE8. And with IE8, so goes jQuery Compat, gone before we even released a final version. There will only be one jQuery from now on!

Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few “breaking changes” that justified the major version bump, but we’re hopeful the breakage doesn’t actually affect that many people. The jQuery Migrate 3.0 plugin, when released, will help you to identify compatibility issues in your code as well. Your feedback on the changes will help us greatly, so please try it out on your existing code and plugins!

You can get the files from the jQuery CDN, or link to them directly:

https://code.jquery.com/jquery-3.0.0-beta1.js

https://code.jquery.com/jquery-3.0.0-beta1.min.js

You can also get the beta version from npm:

Major changes

Below are just the highlights of the major new features, improvements, and bug fixes in these releases. A complete list of changes is available on our GitHub bug tracker.

.show() and .hide() methods

In jQuery 3.0 alpha, we experimented with the idea of treating these methods like an inline-display-none-remover (.show()) and inline-display-none-adder (.hide()). This had the advantage of simplifying these methods greatly and improving performance (it required much fewer calculations). However, this proved to be problematic for our users. Removing inline display:none did not always show the element (if the element was hidden from the stylesheet, for example), and that is far too common. We realized we couldn’t provide a simple way for jQuery plugins, especially, to ensure that an element was shown.

We’ve since reverted that change, and the changes that we’ve kept for the show and hide methods should have much less of an impact on your code. In fact, even with the reversion, we’ve greatly improved performance for the case of hiding many elements.

Special case with `.data()` names

We have updated our .data() implementation to closer match the HTML5 dataset specification. All keys are now converted from kebab-case to camelCase, regardless of access method, and digits no longer participate in the conversion. For example, we will no longer differentiate between “foo-bar” and “fooBar”, but will differentiate between “foo-42” and “foo42”. These changes will mainly come into play when retrieving all data by calling .data() with no arguments, or when trying to access the data using a converted key (.data(“foo42”)) instead of the original (.data(“foo-42”)).

https://github.com/jquery/jquery/issues/1751

jQuery.Deferred is now Promises/A+ compatible

jQuery.Deferred objects have been updated for compatibility with Promises/A+ and ES2015 Promises, verified with the Promises/A+ Compliance Test Suite. This meant we need some major changes to the .then() method:

  • An exception thrown in a .then() callback now becomes a rejection value. Previously, exceptions bubbled all the way up, aborting callback execution and irreversibly locking both the parent and child Deferred objects.
  • The resolution state of a Deferred created by .then() is now controlled by its callbacks—exceptions become rejection values and non-thenable returns become fulfillment values. Previously, returns from rejection handlers became rejection values.
  • Callbacks are always invoked asynchronously. Previously, they would be called immediately upon binding or resolution, whichever came last.
  • Progress callbacks can no longer resolve Deferred objects to which they are bound.

Consider the following, in which a parent Deferred is rejected and a child callback generates an exception:


var parent = jQuery.Deferred();
var child = parent.then( null, function() {
  return "bar";
});
var callback = function( state ) {
  return function( value ) {
    console.log( state, value );
    throw new Error( "baz" );
  };
};
var grandchildren = [
  child.then( callback( "fulfilled" ), callback( "rejected" ) ),
  child.then( callback( "fulfilled" ), callback( "rejected" ) )
];
parent.reject( "foo" );
console.log( "parent resolved" );

As of jQuery 3.0, this will log “parent resolved” before invoking any callback, each child callback will then log “fulfilled bar”, and the grandchildren will be rejected with Error “baz”. In previous versions, this would log “rejected bar” (the child Deferred having been rejected instead of fulfilled) once and then immediately terminate with uncaught Error “baz” (“parent resolved” not being logged and the grandchildren remaining unresolved).

While caught exceptions had advantages for in-browser debugging, it is far more declarative (i.e. explicit) to handle them with rejection callbacks. Keep in mind that this places the responsibility on you to always add at least one rejection callback when working with promises. Otherwise, any errors will go unnoticed.

Legacy behavior can be recovered by replacing use of .then() with the now-deprecated .pipe() method (which has an identical signature).

We’ve also built a plugin to help make debugging Promises/A+ compatible Deferreds. If you figure out that there’s some phantom error getting eaten, check out the jQuery Deferred Reporter Plugin.

jQuery.when has also been updated to accept any thenable object, which includes native Promise objects.

https://github.com/jquery/jquery/issues/1722
https://github.com/jquery/jquery/issues/2102

Added .catch() to Deferreds

The catch() method was added to promise objects as an alias for .then(null, fn).

https://github.com/jquery/jquery/issues/2102

Removed special-case Deferred methods in jQuery.ajax

jqXHR object is a Promise, but also has extra methods like .abort() so that you can stop a request after it has been made.

As users increasingly embrace the Promise pattern for asynchronous work like AJAX, the idea of having special cases for the Promise returned by jQuery.ajax is an increasingly bad idea.

success, error, complete
done, fail, always

Note that this does not have any impact at all on the callbacks of the same name, which continue to exist and are not deprecated. This only affects the Promise methods!

https://github.com/jquery/jquery/issues/2084

Error cases don’t silently fail

Perhaps in a profound moment you’ve wondered, “What is the offset of a window?” Then you probably realized that is a crazy question – how can a window even have an offset?

In the past, jQuery has sometimes tried to make cases like this return something rather than having them throw errors. In this particular case of asking for the offset of a window, the answer up to now has been { top: 0, left: 0 } With this beta of jQuery 3.0 we’re experimenting with the idea of having such cases throw errors so that crazy requests aren’t silently ignored. Please try the beta and see if there is any code out there depending on jQuery to mask problems with invalid inputs.

https://github.com/jquery/jquery/issues/1784

.width(), .height(), .css(“width”), and .css(“height”) to return decimal values (whenever the browser does)

Previously, jQuery rounded values when retrieving width and height. Some browsers return subpixel values – such as IE and Firefox – and sometimes users need this precision when relying on these values for layout. We don’t expect this change to have a big impact on your code, but let us know if it does.

https://github.com/jquery/jquery/issues/1724

Removed deprecated event aliases

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

https://github.com/jquery/jquery/issues/2286

Animations now use requestAnimationFrame

On platforms that support the requestAnimationFrame API, which is pretty much everywhere but IE9 and Android<4.4, jQuery will now use that API when performing animations. This should result in animations that are smoother and use less CPU time – and save battery as well on mobile devices.

jQuery tried using requestAnimationFrame a few years back but there were serious compatibility issues with existing code so we had to back it out. We think we’ve beaten most of those issues by suspending animations while a browser tab is out of view. Still, any code that depends on animations to always run in nearly real-time is making an unrealistic assumption.

.unwrap( selector )

Before jQuery 3.0, the .unwrap() method did not take any arguments. The selector parameter offers a way to be specific about which wrappers to remove.

https://github.com/jquery/jquery/issues/1744

jQuery.fn.domManip no longer accessible

jQuery.dir, jQuery.sibling, jQuery.buildFragment, jQuery.access, and jQuery.swap were all privatized in jQuery 1.12 and 2.2. These methods, along with jQuery.fn.domManip, were always intended for internal use only and were never documented. We are finally making them private to avoid confusion.

https://github.com/jquery/jquery/pull/2182
https://github.com/jquery/jquery/issues/2224
https://github.com/jquery/jquery/issues/2225

Massive speedups for some jQuery custom selectors

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

This change actually made it into 1.12/2.2, but we wanted to reiterate it for jQuery 3.0.

jQuery 2.2 and 1.12 Released

Posted on by

To usher in the new year, the jQuery team has been hard at work on 2 new releases: jQuery 1.12.0 and 2.2.0! These releases include lots of bug fixes and improvements to make your cross-browser development experience better. We anticipate this to be the last releases for the 1.x and 2.x branches before we release jQuery 3.0. Since jQuery 3.0 will have some breaking changes, we will continue to support 1.12 and 2.2 after jQuery 3.0 is released, but only with patches for major regressions. As a side-note, we will have some big news related to jQuery 3.0 coming soon!

Performance Improvements

Performance of the selector engine has improved thanks to a shortcut path that immediately uses precompiled Sizzle selectors when the selector cannot be processed by the native querySelectorAll or matchesSelector methods. This results in a significant speedup in some real-world cases.

New Features

We’ve added some minor, non-breaking features that we thought might be useful in these releases. Here are some of the highlights.

SVG Class Manipulation

While jQuery is a HTML library, we agreed that class support for SVG elements could be useful. Users will now be able to call the .addClass(), .removeClass(), .toggleClass(), and .hasClass() methods on SVG. jQuery now changes the class attribute rather than the className property. This also makes the class methods usable in general XML documents. Keep in mind that many other things will not work with SVG, and we still recommend using a library dedicated to SVG if you need anything beyond class manipulation.

jQuery.post(options) and jQuery.get(options)

These ajax shortcuts have a new signature that takes a single object containing options.

jQuery.post({
  url: “/example”
});

Symbol/iterator support

We’ve added support for the Symbol type and iterators via Symbol.iterator added in ES6/ES2015. “Symbol” will be detectable with jQuery.type, and jQuery objects can be iterated with for-of where supported.

for (element of $elements) {
  console.log(element);
}

jQuery.htmlPrefilter()

A new hook has been added for filtering HTML that is passed to jQuery DOM manipulation methods like .html(), .append(), and .replaceWith(). The default prefilter translates single tags to XHTML-compatible tags. This method will allow users to bypass certain edge cases, remove scripts, and sanitize input.

jQuery.uniqueSort alias

To make it clear that jQuery.unique() also sorts, we’ve update the name. jQuery.unique will still exist, but jQuery.uniqueSort will become the documented method. This method is still only intended to sort DOM elements in document order; it is not a general sorting method.

jQuery 3.0 and jQuery Compat 3.0 Alpha Versions Released

Posted on by

It’s been a long time since we did a major release, and you certainly deserve one. So we’re glad to announce the first alpha of jQuery 3.0!

Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few breaking changes that justified the major version bump, but we’re hopeful these breakages don’t actually affect that many people. The jQuery Migrate plugin can help you to identify compatibility issues in your code as well. Your feedback on the changes in this alpha will help us greatly, so please try it out on your existing code and plugins!

There are actually two releases here. First is jQuery 3.0, which supports modern browsers and environments from IE9 forward. Second is jQuery Compat 3.0, which includes support for IE8. As an added bonus, both jQuery and jQuery Compat will include support for Yandex.Browser, a freeware browser released in 2012. You can get the files from the jQuery CDN, or link to them directly:

https://code.jquery.com/jquery-3.0.0-alpha1.js

https://code.jquery.com/jquery-compat-3.0.0-alpha1.js

You can also get the alpha versions from npm:

npm install [email protected]

npm install [email protected]

 

Major changes

Below are just the highlights of the major new features, improvements, and bug fixes in these releases. A complete list of changes is available at the bottom of this post and on our GitHub issue tracker. On GitHub, you can additionally see the features we expect to put in later beta and final versions that have yet to land.

Simplified .show() and .hide() methods

Everyone’s mental model of jQuery’s .hide() method is that it sets display: none in CSS. Conversely, .show() clears the display so that the element shows again (assuming its parents are not hidden). Simple, right?

Well, no. There are actually many complex special cases that people asked us to “fix” over the years, which turned these methods into a convoluted confluence of principles. For example, what if the element is set to display: none in a stylesheet? jQuery would try to override that by forcing display: block on the element directly. Okay, but what if a normally block element like <li> was set to display: inline by a different stylesheet rule? How about the case where you call these methods on an element before it’s been added to the document and we don’t know what display value it will have? Determining all of that takes extra work. Sometimes it’s still just a guess that turns out to be wrong.

Since these methods add a style attribute to the element, they don’t tend to play well with techniques like responsive design where the visibility of elements may also be set by media queries. This leads to the need for jQuery handlers that listen for the orientationchange or resize events and manually hide or show parts of the page; it defeats the elegant solution that media queries were trying to implement.

You can see that jQuery was already about halfway down the path to total madness, and it didn’t make sense to complete the journey. The special cases and checks were not only complex and incomplete, but they caused significant performance issues on large pages.

So, instead, we’re experimentally defying the evolution of these methods and reverting to a simple, primordial model. This will break some code. If you have elements in a stylesheet that are set to display: none, the .show() method will no longer override that. So the most important rule for moving to jQuery 3.0 is this: Don’t use a stylesheet to set the default of display: none and then try to use .show() – or any method that shows elements, such as .slideDown() and .fadeIn() – to make it visible.

If you need an element to be hidden by default, the best way is to add a class name like “hidden” to the element and define that class to be display: none in a stylesheet. Then you can add or remove that class using jQuery’s .addClass() and .removeClass() methods to control visibility. Alternately, you can have a .ready() handler call .hide() on the elements before they are displayed on the page. Or, if you really must retain the stylesheet default, you can use .css("display", "block") (or the appropriate display value) to override the stylesheet.

We know that this is likely to be one of the most contentious and difficult changes in jQuery 3.0, so we wanted to put it out in this early release to see the effects. Please let us know how it affects your code and what you need to change in order to work with this new model.

Special case with .data() names

We have updated our .data() implementation to closer match the HTML5 dataset specification. All keys are now converted from kebab-case to camelCase, regardless of access method, and digits no longer participate in the conversion. For example, we will no longer differentiate between “foo-bar” and “fooBar”, but will differentiate between “foo-42” and “foo42”. These changes will mainly come into play when retrieving all data by calling .data() with no arguments, or when trying to access the data using a converted key (.data(“foo42”)) instead of the original (.data(“foo-42”)).

https://github.com/jquery/jquery/issues/1751

jQuery.Deferred is now Promises/A+ compatible

jQuery.Deferred objects have been updated for compatibility with Promises/A+ and ES2015 Promises, verified with the Promises/A+ Compliance Test Suite. This meant the introduction of a .catch() method and some major changes to the .then() method:

  • An exception thrown in a .then() callback now becomes a rejection value. Previously, exceptions bubbled all the way up, aborting callback execution and irreversibly locking both the parent and child Deferred objects.
  • The resolution state of a Deferred created by .then() is now controlled by its callbacks—exceptions become rejection values and non-thenable returns become fulfillment values. Previously, returns from rejection handlers became rejection values.
  • Callbacks are always invoked asynchronously. Previously, they would be called immediately upon binding or resolution, whichever came last.
  • Progress callbacks can no longer resolve Deferred objects to which they are bound.

Consider the following, in which a parent Deferred is rejected and a child callback generates an exception:

var parent = jQuery.Deferred();
var child = parent.then( null, function() {
  return "bar";
});
var callback = function( state ) {
  return function( value ) {
    console.log( state, value );
    throw new Error( "baz" );
  };
};
var grandchildren = [
  child.then( callback( "fulfilled" ), callback( "rejected" ) ),
  child.then( callback( "fulfilled" ), callback( "rejected" ) )
];
parent.reject( "foo" );
console.log( "parent resolved" );

As of jQuery 3.0, this will log “parent resolved” before invoking any callback, each child callback will then log “fulfilled bar”, and the grandchildren will be rejected with Error “baz”. In previous versions, this would log “rejected bar” (the child Deferred having been rejected instead of fulfilled) once and then immediately terminate with uncaught Error “baz” (“parent resolved” not being logged and the grandchildren remaining unresolved).

While caught exceptions had advantages for in-browser debugging, it is far more declarative (i.e. explicit) to handle them with rejection callbacks. Keep in mind that this places the responsibility on you to always add at least one rejection callback when working with promises. Otherwise, any errors will go unnoticed.

Legacy behavior can be recovered by replacing use of .then() with the now-deprecated .pipe() method (which has an identical signature).

jQuery.when has also been updated to accept any thenable object, which includes native Promise objects.

https://github.com/jquery/jquery/issues/2102

Removed special-case Deferred methods in jQuery.ajax

jqXHR object is a Promise, but also has extra methods like .abort() so that you can stop a request after it has been made.

As users increasingly embrace the Promise pattern for asynchronous work like AJAX, the idea of having special cases for the Promise returned by jQuery.ajax is an increasingly bad idea.

success, error, complete
done, fail, always

Note that this does not have any impact at all on the callbacks of the same name, which continue to exist and are not deprecated. This only affects the Promise methods!

https://github.com/jquery/jquery/issues/2084

Error cases don’t silently fail

Perhaps in a profound moment you’ve wondered, “What is the offset of a window?” Then you probably realized that is a crazy question – how can a window even have an offset?

In the past, jQuery has sometimes tried to make cases like this return something rather than having them throw errors. In this particular case of asking for the offset of a window, the answer up to now has been { top: 0, left: 0 } With this alpha of jQuery 3.0 we’re experimenting with the idea of having such cases throw errors so that crazy requests aren’t silently ignored. Please try the alpha and see if there is any code out there depending on jQuery to mask problems with invalid inputs.

https://github.com/jquery/jquery/issues/1784

.width(), .height(), .css(“width”), and .css(“height”) to return decimal values (whenever the browser does)

Previously, jQuery rounded values when retrieving width and height. Some browsers return subpixel values – such as IE and Firefox – and sometimes users need this precision when relying on these values for layout. We don’t expect this change to have a big impact on your code, but let us know if it does.

https://github.com/jquery/jquery/issues/1724

Removed deprecated event aliases

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

https://github.com/jquery/jquery/issues/2286

jQuery.swap, jQuery.buildFragment, and jQuery.domManip are no longer accessible on the jQuery object

These methods were always intended for internal use only and were never documented. We are finally making them private to avoid confusion.

https://github.com/jquery/jquery/issues/2224
https://github.com/jquery/jquery/issues/2225

Animations now use requestAnimationFrame

On platforms that support the requestAnimationFrame API, which is pretty much everywhere but IE8 and IE9, jQuery will now use that API when performing animations. This should result in animations that are smoother and use less CPU time – and save battery as well on mobile devices.

jQuery tried using requestAnimationFrame a few years back but there were serious compatibility issues with existing code so we had to back it out. We think we’ve beaten most of those issues by suspending animations while a browser tab is out of view. Still, any code that depends on animations to always run in nearly real-time is making an unrealistic assumption.

.unwrap( selector )

Before jQuery 3.0, the .unwrap() method did not take any arguments. The selector parameter offers a way to be specific about which wrappers to remove.

https://github.com/jquery/jquery/issues/1744

Massive speedups for some jQuery custom selectors

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.
