jsdom 5.4.0

on Node.js NPM

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)
