jQuery 3.4.1: triggering focus events in IE and finding root elements in iOS 10

Posted on by

Hello again! jQuery 3.4.0 was released just three weeks ago, but we’ve had a few issues reported that warranted a patch release. Thank you to everyone that reported issues and helped us get these fixed quickly. Here are the changes:

Triggering focus or blur more than once in IE

jQuery 3.4.0 came with some changes to the way the event handler triggered native events such focus and blur. These changes caused a regression that sometimes resulted in an enigmatic error being thrown in the form of "saved.shift is not a function". This is now fixed.

Example

// Error thrown in IE10-11
// after clicking #test-element twice
jQuery("#test-element").click(function() {
  jQuery(this).trigger("blur");
});

Checking element attachment in iOS 10.0-10.2

When releasing 3.4.0, we ran our tests in several versions of iOS, including iOS 10.3 but not 10.0-10.2. Those versions do not support a native function we use to determine whether an element is attached to the DOM. Other versions of iOS were not affected. We added a guard to ensure that this method exists and fall back to other options if necessary.

Loading jQuery with AMD

A small module was added in jQuery 3.4.0 that used the global jQuery rather than the local jQuery loaded with AMD. This resulted in "jQuery is undefined" errors when loading with AMD, but this should now be fixed.

 


Upgrading

There should be no compatibility issues if upgrading from jQuery 3.0+. If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code.

Please try out this new release and let us know about any issues you experienced.

Slim build

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 web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’ve released a “slim” version that excludes these modules. 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.

jQuery 3.4.0 Released

Posted on by

jQuery has a new release! It’s been a while since our last release, but we expect this to be the last minor release in the 3.x branch, and then we will move on to the overhaul that will be jQuery 4.0. But before we get to 4.0, we’re excited to share the bug fixes and improvements included in jQuery 3.4.0. Here are some of the highlights:

Performance improvement in .width and .height

When getting and setting dimensions, there were certain cases where this could cause layout thrashing, which basically means that the browser calculated layout more times than necessary. We fixed this in all browsers except IE, where it can’t be avoided.

nonce and nomodule support

To support adding script elements through methods like .html and .append, jQuery separates them and appends new script tags to load and execute the remote content. During this process, attributes such as nonce and nomodule were ignored, but jQuery 3.4.0 now hangs onto them.

Radio elements: expected state in event handlers

We had already fixed the same issue with checkboxes, but accidentally left out radio inputs. In the following example, true was logged the first time the element was clicked. We fixed it so that the checked property is updated before the event handler is executed.

Example

var $radios = jQuery(".example");
var $firstRadio = $radios.first();
var firstCheckedState = $firstRadio.prop("checked");
$radio.on("click", function() {
  // true in <3.4.0
  console.log($firstRadio.prop("checked") === firstCheckedState);
});
$radios.eq(1).click();

Minor vulnerability fix: Object.prototype pollution

jQuery 3.4.0 includes a fix for some unintended behavior when using jQuery.extend(true, {}, ...). If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype. This fix is included in jQuery 3.4.0, but patch diffs exist to patch previous jQuery versions.

Example

jQuery.extend(true, {},
  JSON.parse('{"__proto__": {"test": true}}')
);
console.log( "test" in {} ); // true

Note that while jQuery does its best to protect users from security vulnerabilities, jQuery is a DOM manipulation library that will generally do what you tell it to do. In this case, the behavior was likely unexpected, so jQuery.extend will no longer write any properties named __proto__. But guards such as this one are not replacements for good security practices such as user input sanitization.

Deprecating positional selectors and the sunset of Sizzle

The basic API of jQuery is to select something and then do something with what was selected. Sizzle, the selector engine in jQuery, handles the first half. It’s been a fast and efficient little engine that has paved the way for native selector APIs like querySelectorAll and additional native JavaScript and CSS selectors. Now that many of these selectors have made their way into modern browsers, it’s almost time to say goodbye to Sizzle. But in order to remove Sizzle in jQuery 4.0, we will also need to remove what we refer to as positional selectors, which are non-standard selectors.

Specifically, jQuery 3.4.0 is deprecating :first, :last, :eq, :even, :odd, :lt, :gt, and :nth. When we remove Sizzle, we’ll replace it with a small wrapper around querySelectorAll, and it would be almost impossible to reimplement these selectors without a larger selector engine.

We think this trade-off is worth it. Keep in mind we will still support the positional methods, such as .first, .last, and .eq. Anything you can do with positional selectors, you can do with positional methods instead. They perform better anyway.

Bad map file for jQuery 1.9.1 in the jQuery CDN

Posted on by

Quite a while back, Mike Taylor pointed out that the jQuery CDN has a minified copy of jQuery 1.9.1 with an incorrect map file reference. Basically, it refers to the map for jQuery 1.11.1, and that’s just wrong. If you are trying to debug a site that uses the minified jQuery 1.9.1 file, dev tools will get very confused and make a hard job even harder.

You might think that we could just edit the https://code.jquery.com/jquery-1.9.1.min.js file to point to the correct map file, which does exist as https://code.jquery.com/jquery-1.9.1.min.map. There are at least two problems with doing that. The first is that the file is heavily cached across the internet, since it’s been assumed for years that it will never change once the release occurs. Even if we edited the file, both the JavaScript and map file might never actually update at the point where they’re being used.

A second problem is even more serious. We’ve been advocating that developers use the script’s integrity attribute to ensure that the file you are including has not been modified since you originally wrote the script tag. If we modify the contents of the file this attribute will be wrong and the page will no longer include the file. This is likely to completely break the page! Given the age of jQuery 1.9.1 it is possible that many of the pages including this file are not being actively maintained. Thus, we can’t seriously consider changing the JavaScript file in any way, not even one byte.

The least disruptive option is to remove the jquery.min.map file that the jQuery 1.9.1 minified file references. It does not affect whether jQuery runs correctly for the visitors of a site. It only has the effect of disabling the source map. Because of these pitfalls of including the sourceMappingURL map reference in CDN JavaScript files that are often copied elsewhere, we no longer include it.

If you need to debug a site using one of these minified files, it is possible to manually associate a map file in Chrome. Open the minified source file, right click over the area of the minified source, and select “Add source map…”.

The incorrect jquery.min.map file has been removed from the jQuery CDN. We expect that there won’t be any observable change from removing this file, other than restoring sanity to debugging a site that uses jQuery 1.9.1. The jQuery 1.11.1 minified file does not reference its map, so it will continue to work fine and you can associate a map file as mentioned above.

Because caches are so aggressive on CDNs and across the internet, it’s possible that you may still see this map file for a while. If you see some unusual behavior that you think is related to the missing jquery.min.map file you can open a ticket on the CDN issue tracker.

jQuery 3.3.1 – fixed dependencies in release tag

Posted on by

We encountered an issue in the release for jQuery 3.3.0, so we’ve immediately released another tag. The code itself is identical, but our release dependencies (only used during release) were added to the dependencies of the jQuery package itself due to the new behavior of npm in version 5+.

jQuery 3.3.1 is now recommended if installing from npm or GitHub. If using jQuery on any CDN, the built file only differs in the version number.

We apologize for any inconvenience and have updated our release script to account for this issue.

Please see the jQuery 3.3.0 blog post for all relevant code changes in this release.

npm install jquery@3.3.1

Slim build

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’ve released a “slim” version that excludes these modules. 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 – 24k vs 30k. These files are also available in the npm package and on the CDN:

jQuery 3.3.0 – A fragrant bouquet of deprecations and…is that a new feature?

Posted on by

It’s been a while since the last jQuery release, but the Core team hasn’t been idle. We’ve got an all new minor release for you, and it’s even got a new feature in it!

The .addClass(), .removeClass(), and .toggleClass() methods now accept an array of classes.


jQuery(elem).addClass([
   'dave', 'michał', 
   'oleg', 'richard', 
   'jason', 'timmy'
]);

Generally, jQuery is not looking to add anything new. We tend to focus more on what we can remove rather than what we can add. But as soon as we saw this feature request, we wondered how it hadn’t been added before.

There should be no compatibility issues if upgrading from jQuery 3.0+. If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code.

Please try out this new release and let us know about any issues you experienced.

Deprecations

We’ve pruned some roses, lilies, and sunflowers in this release. Some of these will smell sweeter than others, but put them together, and you’ve got a beautiful bouquet of…depre-carnations.

These functions have either lost some of their usefulness over time, are considered to be less favorable than available alternatives, or were intended for internal usage from the beginning. While most of these will be removed in jQuery 4.0, it’s worth noting that we do not consider the deprecation of a method to mean that it will be removed; it means that we encourage the use of alternatives. For instance, event aliases like .click() will likely never be removed.

Command-line Testing

The magnificent Timo Tijhof has made it possible to run all jQuery tests on the command line, using grunt and karma. This is something we’ve always wanted but it was complicated by our need for a php server to run ajax tests. Thanks to Timo for making it happen!

Note: jQuery no longer runs any tests on PhantomJS 1.x.

jQuery 3.2.1 Is Now Available, With Some Hotfixes

Posted on by

jQuery 3.2.1 is now available! This release comes with some hotfixes for regressions that were introduced in the 3.2.0 build four days ago. We wanted to release this patch as quickly as possible to squash any bugs you may have experienced when upgrading. The most significant one had to do with retrieving width or height on an inline element with no explicitly-set dimensions. This should now work as expected. A full list of changes is available below. Also see the 3.2.0 blog post for the bug fixes and improvements that still apply if upgrading from jQuery 3.1.1.

There should be no compatibility issues if upgrading from jQuery 3.0+. If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code.

Please try out this new release and let us know about any issues you experienced.

Changes

Core

  • Ensure jQuery.holdReady is in the right place (#3573, fcc9a9ec)

Dimensions

  • Ensure we get proper values for width and height on elements with display “inline” (#3571, 473d2ea7)

Event

  • Ensure trigger data is passed to radio click event handlers (#3579, a6b07052)
  • Revert: Trigger checkbox and radio click events identically (35785a32).
  • Revert: Add radio click triggering tests (4d6b4536).

jQuery 3.2.0 Is Out!

Posted on by

jQuery 3.2.0 has been released!

This release includes some bug fixes, improvements, and some deprecations. There should be no compatibility issues if upgrading from jQuery 3.0+.

If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code.

Please try out this new release and let us know about any issues you experienced.

Notable Updates

  • Added support for custom CSS properties (#3144).
  • Deprecated jQuery.holdReady (#3288).
  • Deprecated jQuery.nodeName (#3475).
  • Deprecated jQuery.isArray (#2961).
  • Fixed a bug in .width(), .height(), and related methods where CSS transforms were included in the calculations. For instance, an element with the style transform: scale(2x) should not have its width and height values doubled (#3193).
  • Added support for <template> elements to the .contents() method (#3436).
  • Added back the deprecated module to the slim build. This change is largely insignificant given the module’s small size. We believe it makes more sense to remove deprecated pieces from the slim build at the same time as the main jQuery build (#3237).

jQuery 3.1.1 Released!

Posted on by

jQuery 3.1.1 is now available!

This release includes some bug fixes and improvements. As with all patch version releases, there are no new features or intended compatibility issues (if upgrading from jQuery 3.0+) in this release.

We fixed a selector issue with disabled options, exposed jQuery.noConflict even when jQuery is loaded with AMD, and fixed some issues concerning whitespace. We also fixed an issue with the map file that will help when using CDN copies during debugging.

If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code.

Please try out this new release and let us know about any issues you experienced.

GitHub changelog: Issues fixed in 3.1.1 | All changes

Download

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

https://code.jquery.com/jquery-3.1.1.js

https://code.jquery.com/jquery-3.1.1.min.js

You can also get this release from npm:

npm install jquery@3.1.1

Slim build

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’ve released 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-3.1.1.slim.js
https://code.jquery.com/jquery-3.1.1.slim.min.js

These updates are already available as the current versions on npm and Bower. Information on all the ways to get jQuery is available at https://jquery.com/download/. Public CDNs receive their copies today, please give them a few days to post the files. If you’re anxious to get a quick start, use the files on our CDN until they have a chance to update.

Thanks

Many thanks to all of you who participated in this release by testing, reporting bugs, or submitting patches, including Oleg Gaidarenko, Michał Gołębiowski, Richard Gibson, Alexander Lisianoi, Steve Mao, Dave Methvin, and the whole jQuery team.

The jQuery Foundation and Standards

Posted on by

Over the years the jQuery Foundation has worked to give web developers a meaningful voice in the standards process. That’s why we’re excited to help formally establish our involvement in chapters.io, an effort that allows us to work with meetups and supporters around the globe to help developers learn more about recent standards and discuss current proposals.

Our inaugural event will be a regular forum co-organized by one of our own representatives and supported by Pittsburgh, PA’s Code and Supply and Bearded. On Tuesday, August 2nd, Brian Kardell will be presenting at Code and Supply’s regular meetup to talk more about standards and chapters. From there we’ll be organizing the first meeting. If you’re in Pittsburgh and you work on the Web, please come out. If you’re interested in hosting and organizing a meetup in your city, please open an issue on the jQuery Foundation’s standards team GitHub and we’ll try to find someone who can help coordinate.

The jQuery Foundation knows that the Web is at its best when developers are involved, but standards traditionally didn’t include that in their model. Standards were typically driven by browser makers and large companies with a significant stake in the outcome. Sometimes the standard made sense for those groups, but turned out to be less effective when deployed in the harsh reality of the Internet.

In October 2011, Addy Osmani wrote the post announcing the jQuery Standards Team on the blog, naming Yehuda Katz and Paul Irish to help represent the developer community in W3C and TC39. Over the years, numerous jQuery representatives have done a lot to advocate for developers and change the standards process for the better.

Standards have, in fact, improved a lot since then – and jQuery representatives past and present have helped at each step along the way.

In December 2012, we helped elect a slate of candidates to reform the W3C. In 2013, jQuery members like Yehuda Katz, myself (Brian Kardell), Paul Irish and Rick Waldron helped author The Extensible Web Manifesto. This document laid out a new vision for how we could re-focus standards, include the voices of developers and re-imagine a better future. Over the past couple of years, this vision has slowly become a driving force in each of the Web standards bodies. Then, in 2014, it was once again jQuery who called on the W3C’s annual meeting (TPAC) to officially adopt, support and find better ways to involve developers own voices.

The Extensible Web Manifesto is about many of the same principles that Addy expressed in that original post: It encourages standards bodies to give developers a say and create ways to tighten the feedback loop. As Addy eloquently expressed in that original post:

…How often do we all feel our voices, suggestions and ideas are heard by those groups responsible for defining these standards? The reality is that whilst many of us would like to see change, due to time restrictions and lengthy formal processes we’re unable to participate in standards discussions, get involved with writing specifications and contribute to meetings about the future of features. This makes it difficult for web developers to have a voice.

The traditional model of standards involvement does not work at scale. Millions of developers can’t fly to locations around the world for meetings, and a mailing list of millions doesn’t scale either. The aim of Chapters is to provide a conduit between developers and standards that makes it practical for everyone to be involved. If this sounds interesting, take part and get involved! Have your voice be heard!

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.
