7.2.2


Fixed canvasEl.toDataURL(), with the canvas npm package installed; a recent update to the canvas package broke how we were passing arguments to do.
Fixed data: URL parsing to allow empty contents, e.g. data:text/css;base64,. (sebmck)


7.2.1


Fixed a regression in XML parsing of attributes with a namespace URL but no prefix (e.g. <math xmlns="http://www.w3.org/1998/Math/MathML">).


7.2.0


Added support for text selection APIs on <input> and <textarea>! (sjelin and yaycmyk)
Replaced our default XML parser with sax, thus fixing many (but not all) issues with XML and XHTML parsing. To get a flavor of the issues fixed, check out these now-closed bugs: #393, #651, #415, #1276.
Fixed the <canvas> tag to reset its contents when its width or height changed, including the change from the default 300 × 150 canvas. (Applies only when using the canvas npm package.)
Fixed an issue where HTMLCollections would get confused when they contained elements with numeric ids or names.
Fixed an issue with doctype parsing confusing the system ID and public ID.
Made the task posted by postMessage use the inside-jsdom timer queue, instead of the Node.js one. This allows easier mocking. (cpojer)


7.1.1


When <iframe>s have unresolvable URLs, jsdom will no longer crash, but will instead just load about:blank into them. (This is the spec behavior.)
Fixed document.writeln to correctly handle multiple arguments; previously it ignored all after the first.
Fixed FileList objects to no longer have a property named "undefined". (jfremy)


7.1.0

This is a rather large release bringing with it several important re-implementations of DOM and HTML APIs.


Our EventTarget implementation has been rewritten from scratch to follow the spec exactly. This should improve any edge case misbehaviors.
Our Event class hierarchy has been rewritten and fleshed out, fixing many gaps in functionality.


Previously missing classes KeyboardEvent and TouchEvent are now implemented.
Almost all supported Event subclasses now have constructors. (TouchEvent does not yet, and MutationEvent is specified to not have one.)
All classes now have correct public APIs, e.g. getters instead of data properties, missing properties added, and constructors that correctly allow setting all the supported properties.

document.createEvent("customevent", ...) now correctly creates a CustomEvent instead of an Event, and CustomEvent.prototype.initProgressEvent has been replaced with CustomEvent.prototype.initCustomEvent.


The Attr class and related attribute-manipulating methods has been rewritten to follow the latest specification. In particular, Attr is no longer a subclass of Node, and no longer has child text nodes.
The <template> element implementation has been greatly improved, now passing most web platform tests. Its .content property no longer has an extra intermediate document fragment; it no longer has child nodes; and related parts of the parser and serializer have been fixed, including innerHTML and outerHTML, to now work as specified.

querySelector, querySelectorAll, and matches now correctly throw "SyntaxError" DOMExceptions for invalid selectors, instead of just Error instances.

Node.prototype's insertBefore, replaceChild, and appendChild methods now check their arguments more correctly.
The browser builds now have regained the ability to fetch URLs for content and the like; this had been broken due to an issue with the browser-request package, which is no longer necessary anyway.


7.0.2


Fixed an issue where inside jsdom <script> code, /regexpliteral/ instanceof RegExp would be false.


7.0.1


Fixed two bugs with Node.prototype.isEqualNode:


It would previously always return true for comparing any two doctypes.
It would throw an error when trying to compare two elements that had attributes.


Enforced that document.implementation.createDocumentType requires all three of its arguments.


7.0.0

This major release has as its headlining feature a completely re-written XMLHttpRequest implementation, in a heroic effort by @nicolashenry. It includes a number of other smaller improvements and fixes. The breaking changes are highlighted in bold below.


Node.js 4.0 onward is now required, as we have begun using ES2015 features only present there.
Completely re-implemented XMLHttpRequest and related classes (nicolashenry):


Includes support for Blob, File, FileList, FileReader, FormData, ProgressEvent, and the supporting XMLHttpRequestUpload, and XMLHttpRequestEventTarget interfaces.
Includes support for synchronous XHRs.
Adds some new request-management abilities, documented in the readme. In short, the pool, agentOptions, and userAgent options are new, and resource loads can now be aborted.
These implementations are extremely complete and standards-compliant, passing 136 newly-introduced web platform tests.


Added document.charset, an alias for document.characterSet.
Added HTMLTemplateElement.prototype.content, for getting the contents of a <template> element as a document fragment. (rickychien)
Implemented "loose" cookie parsing, giving correct execution of code like document.cookie = "foo".
Several fixes related to event dispatching and creation, including the addition of Event.prototype.stopImmediatePropagation and the constants NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE. This accounted for another 15 newly-passing web platform tests. (nicolashenry)
Fixed document.styleSheets to correctly track the removal of stylesheets from the document. (AVGP)
Fixed the created jsdom lifecycle callback receiving a different window object than the loaded or done callbacks when scripting was enabled.

Invalid URLs are no longer allowed when creating a jsdom document; the URL must be parseable, or an error will be thrown.

The { omitJsdomErrors } option of the virtual console has moved; it is no longer provided when creating the virtual console, but instead when calling sendTo.


6.5.1


Fixed an issue where with jsdom.jsdom, you had to pass referrer and cookie options as top-level, whereas with jsdom.env, you had to nest them under a document option. This was unnecessarily confusing. Now both possibilities are allowed for both functions. (The readme only documents the top-level version, though.)


6.5.0


Added NodeList.prototype[Symbol.iterator], so you can now use for-of loops with NodeLists.


6.4.0


Added jsdom.nodeLocation(node) to get the location within the source text of a given node.
Added jsdom.reconfigureWindow(window, { top }) to allow changing the value of a window's top property.
Added the element argument to the custom resource loader, so you can customize resource loads depending on which element loaded them.
Updated getElementsByClassName to match the spec. It now correctly splits on whitespace to try to find elements with all the given classes; it returns a HTMLCollection instead of a NodeList; and it memoizes the result.
Updated NodeList and HTMLCollection to match the spec. The most noticable change is that HTMLCollection no longer inherits from NodeList.


6.3.0


Added a fully spec-compliant implementation of window.atob and window.btoa. (jeffcarp)
Fixed many issues with our <canvas> implementation:


With the canvas npm package installed, <canvas> elements are now properly instanceof HTMLCanvasElement and instanceof HTMLElement.

<canvas> elements now present the same uniform spec-compliant API both with and without the canvas npm package installed. If the package is not installed, some of the methods will cause not-implemented "jsdomError" events to be emitted on the virtual console.
The width and height properties now correctly reflect the width and height attributes, and have the appropriate default values of 300 and 150.
With the canvas npm package installed, <canvas> elements now generally play better with other parts of jsdom, e.g., document.getElementById actually works with them.


Introduced and upated many of our element classes, so that at least every tag name/element class pair is now correct, even if some of the classes are stubs. In particular:


Complete implementations were added for HTMLDataElement, HTMLSpanElement, and HTMLTimeElement.
Stubs were added for HTMLDataListElement, HTMLDialogElement, HTMLEmbedElement, HTMLMeterElement, HTMLOutputElement, HTMLProgressElement, HTMLSourceElement, HTMLTemplateElement, and HTMLTrackElement.

HTMLAudioElement was implemented in full, although its HTMLMediaElement base, where most of its functionality is, is still largely a stub.

HTMLTableSectionElement, HTMLTableRowElement, HTMLTableCellElement, HTMLTableDataCellElement, and HTMLTableHeaderCellElement were updated to the latest spec.

HTMLIsIndexElement was removed; it has never been produced by the parser since 1.0.0-pre.1, and so it has been just a vestigial global property.
Appropriate constants were added to HTMLMediaElement.


Updated everything having to do with base URLs to be per-spec:


Added Node.prototype.baseURI property to get the node's owner document's base URL.

HTMLBaseElement's href getter now contains appropriate fallbacks and always returns an absolute URL, per spec.
If there are no base elements in an "about:blank" iframe document, the base URL correctly falls back to the parent window's base URL.


When you provide a url: ... option to jsdom.jsom() or jsdom.env(), the given string is now attempted to be resolved as a URL before it is installed as document.URL.


So for example, providing url: "http://example.com" will mean document.URL returns "http://example.com/", with a trailing slash.
In a future major release, we will start throwing if strings that cannot be parsed as valid absolute URL are provided for this option.


6.2.0


Added a full-featured, spec-compliant Element.prototype.classList, closing out a three-year old issue! (wacii)
Made virtualConsole.sendTo(console) forward "jsdomError"s to console by calling console.error. This can be turned off by doing virtualConsole.sendTo(console, { omitJsdomErrors: true }).
Fixed errors when trying to parse invalid doctype declarations, like <!DOCTYPE>.
Fixed spurious "jsdomError"s that were emitted after calling window.close().
Fixed the "DOMSubtreeModified" event to fire in more cases. Note that our mutation events implementation remains incomplete, and will eventually be removed (in a major release) once we implement mutation observers. (selam)


6.1.0


Added basic implementations of HTMLMediaElement and HTMLVideoElement, back-ported from Facebook's Jest project. (cpojer)


6.0.1


Fixed XMLHttpRequest.prototype.getAllResponseHeaders to not crash when used with file: URLs. (justinmchase)
Fixed XMLHttpRequest.prototype.response to correctly return the response text even when responseType was unset. (justinmchase)


6.0.0

This major release is focused on massive improvements in speed, URL parsing, and error handling. The potential breaking changes are highlighted in bold below; the largest ones are around the jsdom.env error-handling paradigm.

This release also welcomes long-time contributer @Joris-van-der-Wel to the core team. You may recognize him from earlier changelogs. We're very happy to have his help in making jsdom awesome!


io.js 2.0 onward is now required, as we have begun using ES2015 features only present there.
Improved performance dramatically, by ~10000x in some cases, due to the following changes:


Overhauled the named properties tracker to not walk the entire tree, thus greatly speeding up the setting of id and name attributes (including during parsing).
Overhauled everything dealing with tree traversal to use a new library, symbol-tree, to turn many operations that were previously O(n²⁾ or O(n) into O(n) or O(1).
Sped up node.compareDocumentPosition and anything that used it (like node.contains) by doing more intelligent tree traversal instead of directly implementing the specced algorithm.


Overhauled how error handling works in jsdom:


window.onerror (or window.addEventListener("error", ...)) now work, and will catch all script errors, similar to in browsers. This also introduces the ErrorEvent class, incidentally.
The virtual console is now the destination for several types of errors from jsdom, using the new event "jsdomError". This includes: errors loading external resources; script execution errors unhandled by window.onerror; and not-implemented warnings resulting from calling methods like window.alert which jsdom explicitly does not support.
Since script errors are now handled by window.onerror and the virtual console, they are no longer included in the initialization process. This results in two changes to jsdom.env and the initialization lifecycle:

The load(errors, window) callback was changed to onload(window), to reflect that it is now just sugar for setting a window.onload handler.

The done(errors, window) callback (i.e., the default callback for jsdom.env) has become done(error, window), and like every other io.js callback now simply gives you a single error object, instead of an array of them.
Nodes no longer have a nonstandard errors array, or a raise method used to put things in that array.


URL parsing and resolution was entirely overhauled to follow the URL standard!


This fixes several long-standing bugs and hacks in the jsdom URL parser, which already had a mess of gross patches on top of the built-in io.js parser to be more web-compatible.
The new URL class has been added to window

The interfaces for HTMLAnchorElement.prototype and document.location (as well as URL, of course) are now uniformized to follow the URLUtils API (minus searchParams for now).
As part of this change, you may need to start passing in file: URLs to jsdom.env where previously you were able to get away with passing in filenames.


Added the XMLHttpRequest.prototype.response getter.
Fixed StyleSheetList.prototype.item to actually work. (chad3814)
Fixed the browser vm shim to properly add the built-in global properties (Object, Array, etc.) to the sandbox. If you were running jsdom inside a web worker and most of your scripts were broken, this should fix that.
Fixed the "hashchange" event to correctly fire HashChangeEvent instances, with correct properties newURL and oldURL (instead of the incorrect newUrl and oldUrl used previously).
Removed usage of the setimmediate library, as it required eval and thus did not work in CSP scenarios.


Finally, if you're a loyal jsdom fan whose made it this far into the changelog, I'd urge you to come join us in #1139, where we are brainstorming a modernized jsdom API that could get rid of many of the warts in the current one.


5.6.1


Fixed an accidentally-created global attribute variable if you ever called createAttributeNS.
Dependency upgrades fixed a couple of bugs, although you would have gotten these anyway with a clean jsdom 5.6.0 install:


Parsing of CSS properties that use url("quoted string") now works correctly, as of cssstyle 0.2.29.
Selectors for the empty string, like div[title=""], now work correctly, as of nwmatcher 1.3.6.


5.6.0


virtualConsole.sendTo now returns this, allowing for a nice shorthand. (jeffcarp)


5.5.0


Added postMessage support, for communicating between parent windows, iframes, and combinations thereof. It's missing a few semantics, especially around origins, as well as MessageEvent source. Objects are not yet structured cloned, but instead passed by reference. But it's working, and awesome! (jeffcarp)
Rewrote cloning code (underlying cloneNode and importNode), fixing a number of issues:


Elements with weird tag names, of the type that only the parser can normally create, can now be cloned (#1142)
Doctypes can now be cloned, per the latest spec.
Attrs cannot be cloned, per the latest spec (although they still have a cloneNode method for now due to legacy).
Document clones now correctly copy over the URL and content-type.


Fixed any virtual console output from iframes to be proxied to the parent window's virtual console. (jeffcarp)
Fixed the type property of <button> elements to correctly default to submit, and to stay within the allowed range.
Fixed clicking on submit <button>s to submit their containing form; previously only <input type="submit"> worked. (rxgx)
Fixed document.open() to return this, per spec. (ryanseddon)


Additionally, Joris-van-der-Wel added a benchmarking framework, and a number of benchmarks, which should help us avoid performance regressions going forward, and also make targeted performance fixes. We're already investigating some real-world issues using this framework. Very exciting!


5.4.3


Incorporated upstream fix for setting el.style.cssText to an invalid value, which should be ignored instead of causing an error to be thrown. This same bug has also caused an error while setting the style attribute to an invalid value, ever since 5.4.0. (Joris-van-der-Wel; chad3814 upstream)


5.4.2


Fixed license metadata to conform to latest npm standards.


5.4.1


Fixed to work with browserify again (regression introduced in 5.4.0).


5.4.0

This is a pretty exciting release! It includes a couple features I never really anticipated jsdom being awesome enough to have, but our wonderful contributors powered through and made them happen anyway:


Added support for the default HTML stylesheet when using window.getComputedStyle! (akhaku)


Notably, this makes jQuery's show() and hide() methods now work correctly; see #994.


Added support for named properties on window: any elements with an id attribute, or certain elements with a name attribute, will cause properties to show up on the window, and thus as global variables within the jsdom. (Joris-van-der-Wel)


Although this is fairly unfortunate browser behavior, it's standardized and supported everywhere, so the fact that jsdom now supports this too means we can run a lot of scripts that would previously fail.
Previously, we only supported this for <iframe>s, and our implementation was quite buggy: e.g., <iframe name="addEventListener"> would override window.addEventListener.
Now that we have the infrastructure in place, we anticipate expanding our support so that this works on e.g. HTMLFormElements as well in the future.


We also have a bunch more fixes and additions:


Implemented the NonDocumentTypeChildNode mixin. Practically, this means adding nextElementSibling and previousElementSibling to Element and the various types of CharacterData. (brandon-bethke-neudesic)
Updated StyleSheetList to inherit from Array, as per the latest CSSOM spec.
Overhauled the handling of attributes throughout the DOM, to follow the spec more exactly.


Our NamedNodeMap implementation is up to date, as are the various Element methods; other places in the code that deal with attributes now all go through a spec-compliant set of helpers.
Some weirdnesses around the style attribute were fixed along the way; see e.g. #1109.
However, Attr objects themselves are not yet spec-compliant (e.g., they still inherit from Node). That's coming soon.


Fixed an unfortunate bug where getElementById would fail to work correctly on <img> elements whose id attributes were modified. (Joris-van-der-Wel)
Fixed the virtualConsole option to work with jsdom.env, not just jsdom.jsdom. (jeffcarp)
Removed a few functions that were erroneously added to window: mapper, mapDOMNodes, and visitTree. (Joris-van-der-Wel)


5.3.0


Added a virtualConsole option to the document creation methods, along with the jsdom.createVirtualConsole factory. (See examples in the readme.) With this option you can install a virtual console before the document is even created, thus allowing you to catch any virtual console events that occur during initialization. (jeffcarp)


5.2.0


Implemented much of the ParentNode mixin (Joris-van-der-Wel):


Moved children from Node to ParentNode, i.e., made it available on Document, DocumentFragment, and Element, but not other types of nodes.
Made children a HTMLCollection instead of a NodeList.
Implemented firstElementChild, lastElementChild, and childElementCount.


Implemented the outerHTML setter. (Joris-van-der-Wel)
Fixed the outerHTML getter for <select> and <form>. (Joris-van-der-Wel)
Fixed various issues with window-less documents, so that they no longer give incorrect results or blow up in strange ways. You can create such documents with e.g. document.implementation.createHTMLDocument(). (Joris-van-der-Wel)
Fixed relative stylesheet resolution when using @import. (dbo)


5.1.0


Added support for the NodeIterator class from the DOM Standard. (Joris-van-der-Wel)
Fixed an issue with the initial request where it was not sharing its cookie jar with the subsequent requests, sometimes leading to a "possible EventEmitter memory leak detected" warning. (inikulin)
Updated tough-cookie to 0.13.0, bringing along many spec compliance fixes. (inikulin)
Added a fast failure in Node.js™ with a clear error message, so that people don't get confused by syntax errors.


5.0.1


Fixed document.cookie setter to no longer ignore null; instead it correctly sets a cookie of "null". (Chrome is not compliant to the spec in this regard.)
Fixed documents created with parsingMode: "xml" to no longer get "<html><head></head><body></body></html>" automatically inserted when calling jsdom.jsdom() with no arguments.
Fixed the innerHTML setter to no longer ignore undefined; instead it correctly sets the innerHTML to "undefined".
Fixed document.write to throw for XML documents as per the spec.
Fixed document.write to accept more than one argument (they get concatenated).
Fixed document.write("") to no longer try to write "<html><head></head><body></body></html>".


5.0.0

This release overhauls how cookies are handled in jsdom to be less fiddly and more like-a-browser. The work for this was done by @inikulin, who is also our beloved parse5 maintainer.

You should only need to worry about upgrading to this release if you use jsdom's cookie handling capabilities beyond the basics of reading and writing to document.cookie. If that describes you, here's what changed:


Removed options.jar and options.document.cookieDomain from the configuration for creating jsdom documents.
Instead, there is now a new option, options.cookieJar, which accepts cookie jars created by the new jsdom.createCookieJar() API. You should use this if you intend to share cookie jars among multiple jsdom documents.
Within a given cookie jar, cookie access is now automatically handled on a domain basis, as the browser does, with the domain calculated from the document's URL (supplied as options.url when creating a document). This supplants the former options.document.cookieDomain.


In addition to these changes to the public API, the following new cookie-related features came along for the ride:


Implemented automatic cookie-jar sharing with descendant <iframe>s. (So, if the iframe is same-domain, it can automatically access the appropriate cookies.)
Let options.document.cookie accept arrays, instead of just strings, for if you want to set multiple cookies at once.


Finally, it's worth noting that we now delegate our cookie handling in general to the tough-cookie package, which should hopefully mean that it now captures many of the behaviors that were previously missing (for example #1027). @inikulin is working on a large pull request to fix tough-cookie to be more spec compliant, which should automatically be picked up by jsdom installs once it is merged.


4.5.1


Removed unnecessary browserify dependency that was erroneously included in 4.5.0.


4.5.0


Added document.currentScript. (jeffcarp)


4.4.0


All resources are now loaded with the request package, which means that e.g. GZIPped resources will be properly uncompressed, redirects will be followed, and more. This was previously the case only for URLs passed directly to jsdom.env, and not for sub-resources inside the resulting page. (ssesha)


4.3.0


Made the click behavior for radio buttons and checkboxes work when doing el.dispatchEvent(clickEvent), not just when doing el.click(). (brandon-bethke-neudesic)
Added defaultPrevented property to Event instances, reflecting whether ev.preventDefault() has been called. (brandon-bethke-neudesic)
Moved the click() method from HTMLInputElement.prototype to HTMLElement.prototype, per the latest spec.
Made the click() method trigger a MouseEvent instead of just an Event.


4.2.0


Added a second parameter to UIEvent, MouseEvent, and MutationEvent, which for now just behaves the same as that for Event. (Rich-Harris)


4.1.0


Added a second parameter to the Event constructor, which allows you to set the bubbles and cancelable properties. (brandon-bethke-neudesic)


4.0.5


Added HTMLUnknownElement and fix the parser/document.createElement to create those instead of HTMLElement for unknown elements.
Fixed issues with named and indexed properties on window, as well as window.length, with regard to <frame>s/<iframe>s being added and removed from the document.


Note: this probably should have been a minor version number increment (i.e. 4.1.0 instead of 4.0.5), since it added HTMLUnknownElement. We apologize for the deviation from semver.


4.0.4


Fixed parsing of doctypes by relying on the information provided by the html parser if possible.


4.0.3


Fixed events fired from EventTargets to execute their handlers in FIFO order, as per the spec.
Fixed a case where childNodes would not be correctly up to date in some cases. (medikoo)
Sped up window creation with jsdom.env by ~600%, for the special case when no scripts are to be executed.


4.0.2


EventTarget is now correctly in the prototype chain of Window.

EventTarget argument validation is now correct according to the DOM Standard.

DOMException now behaves more like it should per Web IDL. In particular it has a more comprehensive set of constants, and instances now have name properties.

new Event("click") can now be dispatched. (lovebear)

document.createEvent now behaves more like it should according to the DOM Standard: it accepts a wider range of arguments, but will throw if an invalid one is given. (lovebear)
Fixed a regression in our browser support that required Chrome 41 as of 4.0.1; now Chrome 40 will work, as well as (in theory, although less well-tested) the latest stable versions of Firefox and IE.


4.0.1


Fixed: Node.prototype.contains to always return a boolean. This was a regression in 3.1.1. (Joris-van-der-Wel)
Fixed: Document.prototype no longer contains its own ownerDocument getter, instead correctly delegating to Node.prototype.
Fixed: some edge cases regarding running <script>s in browserified jsdom.
A couple fixes from updated dependencies (although you would have gotten these anyway with a fresh install, due to floating version specifiers):


csstyle minimum version bumped from 0.2.21 to 0.2.23, fixing handling of 0 when setting numeric CSS properties and parsing of shorthand font declarations.
parse5 minimum version bumped from 1.3.1 to 1.3.2 to, fixing the parsing of <form> elements inside <template> elements.


4.0.0

This release relies on the newly-overhauled vm module of io.js to eliminate the Contextify native module dependency. jsdom should now be much easier to use and install, without requiring a C++ compiler toolchain!

Note that as of this release, jsdom no longer works with Node.js™, and instead requires io.js. You are still welcome to install a release in the 3.x series if you are stuck on legacy technology like Node.js™.

In the process of rewriting parts of jsdom to use vm, a number of related fixes were made regarding the Window object:


In some cases, state was implicitly shared between Window instances—especially parser- and serializer-related state. This is no longer the case, thankfully.
A number of properties of Window were updated for spec compliance: some data properties became accessors, and all methods moved from the prototype to the instance.
The non-standard document.parentWindow was removed, in favor of the standard document.defaultView. Our apologies for encouraging use of parentWindow in our README, tests, and examples.


3.1.2


Some fixes to the NOT_IMPLEMENTED internal helper, which should eliminate the cases where calling e.g. window.alert crashes your application.
Fixed a global variable leak when triggering NOT_IMPLEMENTED methods, like window.location.reload.
Fixed the URL resolution algorithm to handle about:blank properly on all systems (previously it only worked on Windows). This is especially important since as of 3.0.0 the default URL is about:blank.
Fixed, at least partially, the ability to run <script>s inside a browserified jsdom instance. This is done by dynamically rewriting the source code so that global variable references become explicit references to window.variableName, so it is not foolproof.


3.1.1


Updated Node.prototype.isEqualNode to the algorithm of the DOM Standard, fixing a bug where it would throw an error along the way.
Removed Node.prototype.isSameNode, which is not present in the DOM Standard (and was just a verbose === check anyway).
Fixed a couple small issues while browserifying, mainly around jsdom.env. However, while doing so discovered that <script>s in general don't work too well in a browserified jsdom; see #1023.


3.1.0


Added support for custom external resource loading. (tobie)


3.0.3


Fixed some stray byte-order marks in a couple files, which incidentally break Browserify. (sterpe)


3.0.2


Fixed another edge case where unchecking a radio button would incorrectly uncheck radio buttons outside the containing form. (zpao)


3.0.1


Fixed errors when serializing text nodes (possibly only occurred when inside <template>).
Handle null bytes being passed to jsdom.env's autodetecting capabilities. (fluffybunnies)
Handle empty HTML strings being passed to jsdom.env's html option. (fluffybunnies)


3.0.0

This release updates large swathes of the DOM APIs to conform to the standard, mostly by removing old stuff. It also fixes a few bugs, introduces a couple new features, and changes some defaults.

3.0.x will be the last release of jsdom to support Node.js. All future releases (starting with 4.0.0) will require io.js, whose new vm module will allow us to remove our contextify native-module dependency. (Given that I submitted the relevant patch to joyent/node 1.5 years ago, I'm very excited that we can finally use it!)


By default documents now use about:blank as their URL, instead of trying to infer some type of file URL from the call site (in Node.js) or using location.href (in browsers).
Introduced a new "virtual console" abstraction for capturing console output from inside the page. See the readme for more information. Note that console.error will no longer contribute to the (non-standard, and likely dying in the future) window.errors array. (jeffcarp)
Added the named new Image(width, height) constructor. (vinothkr)
Fixed an exception when using querySelector with selectors like div:last-child > span[title].
Removed all traces of entities, entity types, notations, default attributes, and CDATA sections.
Differentiated between XML and HTML documents better, for example in how they handle the casing of tag names and attributes.
Updated DOMImplementation to mostly work per-spec, including removing addFeature and removeFeature methods, the ownerDocument property, and making hasFeature always return true.
Re-did the CharacterData implementation to follow the algorithms in the DOM Standard; this notably removes a few exceptions that were previously thrown.
Re-did Comment, Text, and ProcessingInstruction to follow the DOM Standard and derive from CharacterData.
Re-did DocumentType to follow the DOM Standard and be much simpler, notably removing notations, entities, and default attributes.
Fixed a variety of accessors on Node, Element, Attr, and Document; some were removed that were nonstandard (especially setters); others were updated to reflect the spec; etc.
Re-did name/qname validation, which is done by various APIs, to work with the xml-name-validator package and some centralized algorithms.
Made the XML parser at least somewhat aware of processing instructions.
Cleaned up doctype parsing and association between doctypes and documents. More exotic doctypes should parse better now.

document.contentType now is generally inferred from the parsing mode of the document.
Moved some properties to Document.prototype and Window.prototype instead of setting them as own properties during the document/window creation. This should improve memory usage (as well as spec compliance).


2.0.0

This release is largely a refactoring release to remove the defunct concept of "levels" from jsdom, in favor of the living standard model that browsers follow. Although the code is still organized that way, that's now noted as a historical artifact. The public API changes while doing so were fairly minimal, but this sets the stage for a cleaner jsdom code structure going forward.


Removed: jsdom.level, and the level option from jsdom.jsdom.
Change: the nonstandard Element.prototype.matchesSelector method was replaced with the standard Element.prototype.matches. (KenPowers)
Fix: querySelector correctly coerces its argument to a string (1.2.2 previously fixed this for querySelectorAll).


1.5.0


Add: missing window.console methods, viz. assert, clear, count, debug, group, groupCollapse, groupEnd, table, time, timeEnd, and trace. All except assert do nothing for now, but see #979 for future plans. (jeffcarp)
Tweak: make childNodes, and the many places in jsdom that use it, much faster. (Joris-van-der-Wel)


1.4.1


Tweak: faster implementation of NodeList.prototype.length, which should speed up common operations like appendChild and similar. (Joris-van-der-Wel)


1.4.0


Fix: HTMLInputElement.prototype.checked and defaultChecked now behave per the spec. (Joris-van-der-Wel)
Fix: HTMLOptionElement.prototype.selected now behaves per the spec. (Joris-van-der-Wel)
Fix: HTMLInputElement.prototype.value now behaves per the spec. (Joris-van-der-Wel)
Fix: HTMLTextAreaElement.prototype.value and defaultValue now behave per the spec. (Joris-van-der-Wel)
Add: HTMLTextAreaElement.prototype.defaultValue now has a setter, and HTMLTextAreaElement.prototype.textLength now exists. (Joris-van-der-Wel)
Fix: resetting a <form> now behaves per spec for all different types of form elements. (Joris-van-der-Wel)
Fix: radio buttons reset other radio buttons correctly now per the spec. (Joris-van-der-Wel)
Fix: document.cloneNode now works. (AVGP)
Fix: hasAttribute is now case-insensitive, as it should be. (AVGP)
Fix: div.toString() now returns [object HTMLDivElement]. (AVGP)


1.3.2


Fix: check if module.parent exists before using it to construct a document's initial URL. Apparently some testing frameworks like Jest do not correctly emulate the module environment; this compensates. (SegFaultx64)


1.3.1


Fix: changing attributes on <option> elements will now have the correct consequences. For example changing the id attribute now interacts correctly with document.getElementById. (Joris-van-der-Wel)


1.3.0


Add: moved focus and blur methods to HTMLElement.prototype, instead of having them only be present on certain element prototypes. Our focus story is still not very spec-compliant, but this is a step in the right direction. (vincentsiao)


1.2.3


Tweak: improve performance of Node.prototype.insertBefore, Node.prototype.removeChild, and several AttributeList methods. (Joris-van-der-Wel)


1.2.2


Fix: querySelectorAll correctly coerces its argument to a string; notably this allows you to pass arrays. (jeffcarp)
Fix: the data setter on text nodes correctly coerces the new value to a string. (medikoo)
Fix: document.toString() now returns [object HTMLDocument]. (jeffcarp)


1.2.1


Fix: handling of <template> element parsing and serialization, now that it is supported by parse5. (inikulin)


1.2.0


Add: NodeFilter, in particular its constants. (fhemberger)
Fix: initial history.length should be 1, not 0. (rgrove)
Fix: history.pushState and history.replaceState should not fire the popstate event. (rgrove)


1.1.0


Add: document.implementation.createHTMLDocument(). (fhemberger)
Fix: localName was sometimes null for elements when it should not be. (fhemberger)


1.0.3


Update: no longer requiring separate cssstyle and cssstyle-browserify dependencies; now cssstyle can be used directly. This also un-pins the cssstyle dependency so that future fixes arrive as they appear upstream.


1.0.2


Fix: temporarily pin cssstyle dependency to at most 0.2.18 until chad3814/CSSStyleDeclaration#20 is fixed.
Fix: browserifying jsdom should work better now that the required packages are included as dependencies instead of devDependencies. (Sebmaster)
Fix: using jsom.env in a browser environment now correctly defaults options.url to location.href instead of trying to infer a reasonable fil:// URL using techniques that fail in the browser. (rattrayalex)


1.0.1


Fix: the return value of EventTarget.prototype.dispatchEvent should be true when the default is not prevented; previously it was the opposite. (eventualbuddha)


1.0.0

For a consolidated list of changes from 0.11.1 to 1.0.0, see this wiki page.


Remove: nonstandard EventTarget.getListeners; EventTarget.forwardIterator; EventTarget.backwardIterator; EventTarget.singleIterator.
Remove: nonstandard document.innerHTML. (jorendorff)
Fix: value and defaultValue properties of a HTMLInputElement are now correctly synced to the value="" attribute. (Sebmaster)


1.0.0-pre.7


Remove: support for old, untested HTML and XML parsers, namely davglass/node-htmlparser and isaacs/sax-js. In the future we plan to work toward a standardized parsing interface that other parsers can implement, instead of adding custom code to jsdom for various parsers. This interface still is being decided though, as it needs to support complex things like pausing the parse stream (for document.write) and parsing disconnected fragments (for document.innerHTML). (Sebmaster)
Add: new parsingMode configuration, to allow you to manually specify XML or HTML. (Sebmaster)
Change: jsdom will no longer use the presence of <?xml or similar to attempt to auto-detect XHTML documents. Instead, it will by default treat them the same as browsers do, with the <?xml declaration just being a bogus comment. If you need your document interpreted as XHTML instead of HTML, use the parsingMode option. (Sebmaster)
Tweak: memoize various DOM-querying functions (e.g. getElementsByTagName, querySelector, etc.) to improve performance. (ccarpita)


1.0.0-pre.6


Fix: another parsing issues with void elements and innerHTML, this time related to disconnected nodes. This was a regression between 0.11.1 and 1.0.0-pre.1. (paton)
Fix: same-named radio inputs should not be mutually exclusive unless they are in the same form. (stof)


1.0.0-pre.5


Fix: sometimes calling window.close() would cause a segfault. (paton)


1.0.0-pre.4


Fix: attributes and elements now have their prefix, localName, and namespaceURI properties set correctly in all cases. (Excepting application/xhtml+xml mode, which jsdom does not support yet.) (Sebmaster)


1.0.0-pre.3


Fix: void elements no longer parsed correctly when using innerHTML. This was a regression between 0.11.1 and 1.0.0-pre.1. (Sebmaster)


1.0.0-pre.2


Fix: parsing and serialization of attributes in the form x:y, e.g. xmlns:xlink or xlink:href. This was a regression between 0.11.1 and 1.0.0-pre.1. (Sebmaster)


1.0.0-pre.1

This is a prerelease of jsdom's first major version. It incorporates several great additions, as well as a general cleanup of the API surface, which make it more backward-incompatible than usual. Starting with the 1.0.0 release, we will be following semantic versioning, so that you can depend on stability within major version ranges. But we still have a few more issues before we can get there, so I don't want to do 1.0.0 quite yet.

This release owes a special thanks to @Sebmaster, for his amazing work taking on some of the hardest problems in jsdom and solving them with gusto.


Major changes


jsdom now can be browserified into a bundle that works in web workers! This is highly experimental, but also highly exciting! (lawnsea)
An overhaul of the initialization lifecycle, to bring more control and address common use cases. (Sebmaster)
The excellent parse5 HTML parser is now the default parser, fixing many parsing bugs and giving us full, official-test-suite-passing HTML parsing support. This especially impacts documents that didn't include optional tags like <html>, <head>, or <body> in their source. We also use parse5 for serialization, fixing many bugs there. (Sebmaster)
As part of the new parser story, we are not supporting XML for now. It might work if you switch to a different parser (e.g. htmlparser2), but in the end, HTML and XML are very different, and we are not attempting to be an XML DOM. That said, we eventually want to support XML to the same extent browsers do (i.e., support XHTML and SVG, with an appropriate MIME type switch); this is being planned in #820.


Removed jsdom APIs


jsdom.createWindow: use document.parentWindow after creating a document

jsdom.html: use jsdom.jsdom


jsdom.version: use require("jsdom/package.json").version


jsdom.level: levels are deprecated and will probably be removed in 2.0.0
jsdom.dom
jsdom.browserAugmentation
jsdom.windowAugmentation


Changed jsdom APIs


jsdom.jsdom no longer takes a level as its second argument.

jsdom.jQueryify now requires a jQuery URL, since always picking the latest was a bad idea.


Removed non-standard DOM APIs


document.createWindow: use document.parentWindow


document.innerHTML and document.outerHTML: use the new jsdom.serializeDocument to include the DOCTYPE, or use document.documentElement.outerHTML to omit it.


Other fixes


Allow empty strings to be passed to jsdom.env. (michaelmior)
Fix for a memory leak in EventTarget.prototype.dispatchEvent. (Joris-van-der-Wel)
Make event listeners in the capture phase also fire on the event target. (Joris-van-der-Wel)
Correctly reset eventPhase and currentTarget on events, before and after a dispatch. (Joris-van-der-Wel)

0.11.1


Add: Node.prototype.parentElement. (lukasbuenger)
Fix: attributes that are reflected as properties should be '' when not present, instead of null. (Note that getAttribute still returns null for them). (thejameskyle)
Fix: textContent now works for nodes that do not have children, like text nodes for example. (hayes)
Fix: jsdom.jQueryify was using the wrong URL for jQuery by default. (lukasbuenger)


0.11.0


Add: new default level, living, reflecting our focus on the DOM Living Standard and the HTML Living Standard, which are what browsers actually implement. This should open the door for more features of the modern DOM and HTML specs to be implemented in jsdom. (robotlovesyou)
Add: Node.prototype.contains now implemented. (robotlovesyou)
Add: navigator.cookieEnabled now implemented; it always returns true. (Sebmaster)
Change: DOCTYPEs no longer have their name property uppercased during parsing, and appear in the output of document.innerHTML.
Fix: Node.prototype.compareDocumentPosition implemented correctly; various document position constants added to the Node constructor. (robotlovesyou)
Fix: DocumentType.prototype.parentNode now returns the document node, not null. (robotlovesyou)
Fix: various navigator properties are now getters, not data properties. (Sebmaster)
Fix: a bug involving invalid script paths and jsdom.jQueryify. (Sebmaster)


0.10.6


Add: remaining URL properties to window.location and HTMLAnchorElement.
Fix: the presence of String.prototype.normalize, which is available by default in Node 0.11.13 onwards, caused reflected attributes to break. (brock8503)
Fix: iframes now correctly load about:blank when the src attribute is empty or missing. (mcmathja)
Fix: documents containing only whitespace now correctly generate wrapper documents, just like blank documents do. (nikolas)
Tweak: lazy-load the request module, to improve overall jsdom loading time. (tantaman)


0.10.5


Fix: the list of void elements has been updated to match the latest HTML spec.
Fix: when serializing void elements, don't include a /: i.e. the result is now <br> instead of <br />.


0.10.4


Fix: another case was found where jQuery 1.11's show() method would cause errors.
Add: querySelector and querySelectorAll methods to DocumentFragments. (Joris-van-der-Wel)


0.10.3

0.10.2


Fix: Using jQuery 1.11's show() method would cause an error to be thrown.
Fix: window.location properties were not updating correctly after using pushState or replaceState. (toomanydaves)


0.10.1


Fix: window.location.port should default to "", not null. (bpeacock)


0.10.0


Add: a more complete document.cookie implementation, that supports multiple cookies. Note that options like path, max-age, etc. are still ignored. (dai-shi)


0.9.0


Add: implement attribute ordering semantics from WHATWG DOM spec, and in general overhaul attribute storage implementation to be much more awesome and accurate. (lddubeau)
Add: port and protocol to HTMLAnchorElement. (sporchia)
Fix: make HTMLInputElement not have a type attribute by default. It still has a default value for the type property, viz. "text". (aredridel)
Fix: treat empty namespace URI as meaning "no namespace" with the getAttributeNS, hasAttributeNS, and setAttributeNS functions. (lddubeau)
Fix: reference typed arrays in a way that doesn't immediately break on Node 0.6. Node 0.6 isn't supported in general, though. (kangax)


0.8.11


Add: store and use cookies between requests; customizable cookie jars also possible. (stockholmux)
Fix: attributes named the same as prototype properties of NamedNodeMap no longer break jsdom. (papandreou)
Fix: removeAttributeNS should not throw on missing attributes. (lddubeau)
Change: remove __proto__, __defineGetter__, and __defineSetter__ usage, as part of a project to make jsdom work better across multiple environments. (lawnsea)


0.8.10


Add: hash property to HTMLAnchorElement. (fr0z3nk0)


0.8.9


Upgrade: cssom to 0.3.0, adding support for @-moz-document and fixing a few other issues.
Upgrade: cssstyle to 0.2.6, adding support for many shorthand properties and better unit handling.


0.8.8


Fix: avoid repeated NodeList.prototype.length calculation, for a speed improvement. (peller)


0.8.7


Add: host property to HTMLAnchorElement. (sporchia)


0.8.6

Add: a dummy getBoundingClientRect method, that returns 0 for all properties of the rectangle, is now implemented. (F1LT3R)


0.8.5


Add: href property on CSSStyleSheet instances for external CSS files. (FrozenCow)


0.8.4


Add: typed array constructors on the window. (nlacasse)
Fix: querySelector and querySelectorAll should be on the prototypes of Element and Document, not own-properties. (mbostock)


0.8.3


Fix: when auto-detecting whether the first parameter to jsdom.env is a HTML string or a filename, deal with long strings correctly instead of erroring. (baryshev)


0.8.2


Add: basic window.history support, including back, forward, go, pushState, and replaceState. (ralphholzmann)
Add: if an <?xml?> declaration starts the document, will try to parse as XML, e.g. not lowercasing the tags. (robdodson)
Fix: tag names passed to createElement are coerced to strings before evaluating.


0.8.1 (hotfix)


Fix: a casing issue that prevented jsdom from loading on Unix and Solaris systems. (dai-shi)

Add: working XMLHttpRequest support, including cookie passing! (dai-shi)
Add: there is now a window.navigator.noUI property that evaluates to true, if you want to specifically distinguish jsdom in your tests.


0.7.0


Change: the logic when passing jsdom.env a string is more accurate, and you can be explicit by using the html, url, or file properties. This is a breaking change in the behavior of html, which used to do the same auto-detection logic as the string-only version.
Fix: errors raised in scripts are now passed to jsdom.env's callback. (airportyh)
Fix: set window.location.href correctly when using jsdom.env to construct a window from a URL, when that URL causes a redirect. (fegs)
Add: a more complete and accurate window.location object, which includes firing hashchange events when the hash is changed. (dai-shi)
Add: when using a non-implemented feature, mention exactly what it was that is not implemented in the error message. (papandreou)


0.6.5


Fix: custom attributes whose names were the same as properties of Object.prototype, e.g. "constructor", would confuse jsdom massively.


0.6.4


Fix: CSS selectors which contain commas inside quotes are no longer misinterpreted. (chad3814)
Add: <img> elements now fire "load" events when their src attributes are changed. (kapouer)


0.6.3


Fix: better automatic detection of URLs vs. HTML fragments when using jsdom.env. (jden)


0.6.2


Fix: URL resolution to be amazing and extremely browser-compatible, including the interplay between the document's original URL, any <base> tags that were set, and any relative hrefs. This impacts many parts of jsdom having to do with external resources or accurate href and src attributes. (deitch)
Add: access to frames and iframes via named properties. (adrianlang)
Fix: node-canvas integration, which had been broken since 0.5.7.


0.6.1


Make the code parseable with Esprima. (squarooticus)
Use the correct package.json field "repository" instead of "repositories" to prevent npm warnings. (jonathanong)


0.6.0

Integrated a new HTML parser, htmlparser2, from fb55. This is an actively maintained and much less buggy parser, fixing many of our parsing issues, including:


Parsing elements with optional closing tags, like <p> or <td>.
The innerHTML of <script> tags no longer cuts off the first character.
Empty attributes now have "" as their value instead of the attribute name.
Multiline attributes no longer get horribly mangled.
Attribute names can now be any value allowed by HTML5, including crazy things like ^.
Attribute values can now contain any value allowed by HTML5, including e.g. > and <.


0.5.7


Fix: make event handlers attached via on<event> more spec-compatible, supporting return false and passing the event argument. (adrianlang)
Fix: make the getter for textContent more accurate, e.g. in cases involving comment nodes or processing instruction nodes. (adrianlang)
Fix: make <canvas> behave like a <div> when the node-canvas package isn't available, instead of crashing. (stepheneb)


0.5.6


Fix: on<event> properties are correctly updated when using setAttributeNode, attributeNode.value =, removeAttribute, and removeAttributeNode; before it only worked with setAttribute. (adrianlang)
Fix: HTMLCollections now have named properties based on their members' id and name attributes, e.g. form.elements.inputId is now present. (adrianlang)


0.5.5


Fix: readOnly and selected properties were not correct when their attribute values were falsy, e.g. <option selected="">. (adrianlang)


0.5.4

This release, and all future releases, require at least Node.js 0.8.


Add: parser can now be set via jsdom.env configuration. (xavi-)
Fix: accessing rowIndex for table rows that are not part of a table would throw. (medikoo)
Fix: several places in the code accidentally created global variables, or referenced nonexistant values. (xavi-)
Fix: <img> elements' src properties now evaluate relative to location.href, just like <a> elements' href properties. (brianmaissy)


0.5.3

This release is compatible with Node.js 0.6, whereas all future releases will require at least Node.js 0.8.


Fix: getAttributeNS now returns null for attributes that are not present, just like getAttribute. (mbostock)
Change: "request" dependency pinned to version 2.14 for Node.js 0.6 compatibility.


0.5.2


Fix: stylesheets with @-webkit-keyframes rules were crashing calls to getComputedStyle.
Fix: handling of features option to jsdom.env.
Change: retain the value of the style attribute until the element's style property is touched. (papandreou)


0.5.1


Fix: selectedIndex now changes correctly in response to <option> elements being selected. This makes <select> elements actually work like you would want, especially with jQuery. (xcoderzach)
Fix: checked works correctly on radio buttons, i.e. only one can be checked and clicking on one does not uncheck it. Previously they worked just like checkboxes. (xcoderzach)
Fix: click() on <input> elements now fires a click event. (xcoderzach)


0.5.0


Fix: Make contextify a non-optional dependency. jsdom never worked without it, really, so this just caused confusion.


0.4.2


Fix: selected now returns true for the first <option> in a <select> if nothing is explicitly set.
Fix: tweaks to accuracy and speed of the querySelectorAll implementation.


0.4.1 (hotfix)


Fix: crashes when loading HTML files with <a> tags with no href attribute. (eleith)


0.4.0


Fix: getAttribute now returns null for attributes that are not present, as per DOM4 (but in contradiction to DOM1 through DOM3).
Fix: static NodeList-returning methods (such as querySelectorAll) now return a real NodeList instance.
Change: NodeLists no longer expose nonstandard properties to the world, like toArray, without first prefixing them with an underscore.
Change: NodeLists no longer inconsistently have array methods. Previously, live node lists would have indexOf, while static node lists would have them all. Now, they have no array methods at all, as is correct per the specification.


0.3.4


Fix: stylesheets with @media rules were crashing calls to getComputedStyle, e.g. those in jQuery's initialization.


0.3.3


Fix: make document.write calls insert new elements correctly. (johanoverip, kblomquist).
Fix: <input> tags with no type attribute now return a default value of "text" when calling inputEl.getAttribute("type").


0.3.2


Fix: stylesheets with "joining" rules (i.e. those containing comma-separated selectors) now apply when using getComputedStyle. (chad3814, godmar)
Add: support for running the tests using @aredridel's html5 parser, as a prelude toward maybe eventually making this the default and fixing various parsing bugs.


0.3.1 (hotfix)


Fix: crashes when invalid selectors were present in stylesheets.


0.3.0


Fix: a real querySelector implementation, courtesy of the nwmatcher project, solves many outstanding querySelector bugs.
Add: matchesSelector, again via nwmatcher.
Add: support for styles coming from <style> and <link rel="stylesheet"> elements being applied to the results of window.getComputedStyle. (chad3814)
Add: basic implementation of focus() and blur() methods on appropriate elements. More work remains.
Fix: script filenames containing spaces will now work when passed to jsdom.env. (TomNomNom)
Fix: elements with IDs toString, hasOwnProperty, etc. could cause lots of problems.
Change: A window's load event always fires asynchronously now, even if no external resources are necessary.
Change: turning off mutation events is not supported, since doing so breaks external-resource fetching.


0.2.19


Fix: URL resolution was broken on pages that included href-less <base> tags.
Fix: avoid putting attr in the global scope when using node-canvas. (starsquare)
Add: New SkipExternalResources feature accepts a regular expression. (fgalassi)


0.2.18


Un-revert: cssstyle has fixed its memory problems, so we get back accurate cssText and style properties again.


0.2.17 (hotfix)


Revert: had to revert the use of the cssstyle package. cssText and style properties are no longer as accurate.
Fix: cssstyle was causing out-of-memory errors on some larger real-world pages, e.g. reddit.com.


0.2.16


Update: Sizzle version updated to circa September 2012.
Fix: when setting a text node's value to a falsy value, convert it to a string instead of coercing it to "".
Fix: Use the cssstyle package for CSSStyleDeclaration, giving much more accurate cssText and style properties on all elements. (chad3814)
Fix: the checked property on checkboxes and radiobuttons now reflects the attribute correctly.
Fix: HTMLOptionElement's text property should return the option's text, not its value.
Fix: make the name property only exist on certain specific tags, and accurately reflect the corresponding name attribute.
Fix: don't format outerHTML (especially important for <pre> elements).
Fix: remove the value property from Text instances (e.g. text nodes).
Fix: don't break in the presence of a String.prototype.normalize method, like that of sugar.js.
Fix: include level3/xpath correctly.
Fix: many more tests passing, especially related to file:/// URLs on Windows. Tests can now be run with npm test.

Fix: when serializing single tags use ' />' instead of '/>' (kapouer)
Fix: support for contextify simulation using vm.runInContext (trodrigues)
Fix: allow jsdom.env's config.html to handle file paths which contain spaces (shinuza)
Fix: Isolate QuerySelector from prototype (Nao Iizuka)
Add: setting textContent to '' or clears children (Jason Davies)
