Changelog

5.0.0

  • Changed code formatting to use dangling commas where ES5 supports them.
  • Fixed a bug where <audio controls /> and <video controls /> elements without tabindex attribute specified would be deemed NOT tabbable in Chrome, but would be in FireFox, because Chrome has tabIndex (the DOM Element property) returning -1 (focusable, but not tabbable), while FireFox has tabIndex returning 0 (focusable, and tabbable), yet both browsers include these elements in the regular tab order (as if tabIndex was 0 for both browsers). Now these elements are considered tabbable in Chrome too!
  • Add any <summary> element directly under a <details> element as tabbable and focusable.
  • BREAKING: Changes to the isTabbableRadio() internal function in order to better support nested radio buttons:
    • In case a form parent element exists, include only nested radio inputs from that form.
    • Ignore checked radio elements from forms different from the one the validated node belongs to.
    • NOTE: This may result in less radio elements being flagged as tabbable depending on context from the "root" node given to tabbable().
  • BREAKING: The exports have changed to be all named, and separate, as follows in order to help make the module more compatible with tree shaking:
    • tabbable -> `import { tabbable } from 'tabbable';
    • tabbable.isTabbable -> `import { isTabbable } from 'tabbable';
    • tabbable.isFocusable -> `import { isFocusable } from 'tabbable';
  • Also to help with tree shaking, package.json now states sideEffects: false to mark this module as having no side effects as a result of merely importing it.
  • Added new UMD build, see ./dist/index.umd.*.

4.0.0

  • Improve performance by changing the method for detecting whether a DOM node is focusable or not. It's expected that this change will not affect results; but this is a major version bump as a warning for you to check your edge cases before upgrading.

3.1.2

  • Fix reference to root element that caused errors within Shadow DOM.

3.1.1

  • Allow module to be imported by non-browser JavaScript.

3.1.0

  • Add tabbable.isFocusable and tabbable.isTabbable functions.

3.0.0

  • Add [contenteditable] elements.

2.0.0

  • Add <audio> and <video> elements with controls attributes.
  • Only consider radio buttons tabbable if they are the checked on in their group, or if none in their group are checked.

1.1.3

  • Fix bug causing SVG elements to precede elements they should follow in the tab order in IE.

1.1.2

  • Ensure querySelectorAll receives a string argument.

1.1.1

  • Fix crash when you call tabbable(document) (passing the document element).

1.1.0

  • Add includeContainer option.

1.0.8

  • Allows operation against elements that reside within iframes, by inspecting the element to determine its correct parent document (rather than relying on the global document object).

1.0.7

  • Ensure stable sort of tabindexed elements even in browsers that have an unstable Array.prototype.sort.

1.0.6

  • Check tabindex attribute (via getAttribute), in addition to node.tabIndex, to fix handling of SVGs with tabindex="-1" in IE.

1.0.5

  • Children of visibility: hidden elements that themselves have visibility: visible are considered tabbable.

1.0.4

  • Fix IE9 compatibility.

1.0.3

  • Further improvements to caching.

1.0.2

  • Fix overaggressive caching that would prevent tabbable from knowing an element's children had changed.

1.0.1

  • Fix handling of <a> elements with tabindex="0".

1.0.0

  • Initial release.
