Changelog

5.3.3

Patch Changes

• 0210a1c: fix: align with browser behaviour when a web component has a negative tabindex

5.3.2

Patch Changes

• 320bfd1: Updated docs for displayCheck configuration.
• aa2a699: Fixed an issue with displayCheck=full (default setting) determining all nodes were hidden when the container is not attached to the document. In this case, tabbable will revert to a displayCheck=none mode, which is the equivalent legacy behavior. Also updated the displayCheck option docs to add warnings about this corner case for the full and non-zero-area modes. non-zero-area behaves differently in the corner case. See the docs for more info.

5.3.1

Patch Changes

• cf1da66: Add warnings and help in documentation about running tabbable under JSDom (e.g. with Jest). JSDom is not technically supported, and 5.3.0 introduced some changes that use DOM APIs that JSDom stubs out, which may cause some JSDom-based tests to fail. Also revamp the API docs a bit to make them clearer, and add missing getShadowRoot option to isTabbable() and isFocusable() (docs only; no code changes necessary).

5.3.0

Minor Changes

• 685a906: Adds new Shadow DOM support (must be explicitly enabled using the new getShadowRoot option).
  • When enabled, supports open shadows by default, and can support closed shadows if the option is a function that returns the shadow for a given node. See documentation for more information.
  • Includes all updates from 5.3.0-beta.0 and 5.3.0-beta.1 releases.

Patch Changes

• b341412: Made "isDisabledFromFieldset" more readable and concise (even marginally faster).
• 685a906: Fixed a bug in getTabIndex: the tab index of <audio>, <video> and <details> was left to the browser default if explicitly set to a value that couldn't be parsed as integer, leading to inconsistent behavior across browsers. Also slightly modified the function's logic to make it more efficient. Finally added tests to cover the fix.
• dd6d0ec: Optimized and extended displayCheck: "full" option (now checks for any element having no display boxes) and added test for display: "contents" property (this bug was never reported). (#592)
  • ⚠️ This will likely break your tests if you're using JSDom (e.g. with Jest). See testing in JSDom for more info.
• 193fca2: Fixed bug in isDisabledFromFieldset. The function wasn't checking whether the disabled <fieldset> containing node is the top-most disabled <fieldset> (#596).

5.3.0-beta.1

• Add support for setting getShadowRoot: true as an easy way to simply enable shadow DOM support. This is the equivalent of setting getShadowRoot: () => false, which means tabbable will find nodes in open shadow roots only.

5.3.0-beta.0

• Includes new Shadow DOM support for open shadows by default
• Includes a new getShadowRoot() configuration option, enabling support for closed shadows

5.2.1

Patch Changes

• 1d5fcb5: Fixed: Form elements in disabled fieldsets should not be tabbable/focusable (#413)

5.2.0

Minor Changes

• bf0a8f0: Exposed an option to select the way that an element is checked as displayed

5.1.6

Patch Changes

• f9f6d25: Replaces Karma/Mocha/Sinon/Chai in test suite with Jest/Dom Testing Library. Removes README reference to identifying anchor tags with an xlink:href attribute as tabbable since that information is incorrect.

5.1.5

Patch Changes

• c048203: fix crash when radio button name attributes contain CSS selector special characters (#168)

5.1.4

Patch Changes

• a188c71: use element.matches fallback for IE11 and Webkit5
• 0d4cdf8: Update the code to use const/let and function declarations only for the repo; this does NOT affect browser compatibility as the code is still transpiled when published into the ./dist directory for various targets.

5.1.3

Patch Changes

• 5579825: fixes to details elements
  • ignore elements nested under a closed details element
  • ignore any extra summary elements after the first summary element
  • add details element as tabbable in case it has no direct summary element

5.1.2

Patch Changes

• d3c6514: Fix UMD build incorrectly using focusTrap as output name.
• 95563c2: Fix #99: Transpile ESM bundle down to the same browser target used for the CJS and UMD bundles. ESM is just the module system, not the browser target.

5.1.1

Patch Changes

• fb49d23: Fix #96: Transpile non-minified bundles for expected browser targets.

5.1.0

Minor Changes

• bd21d91: Add focusable() for getting all focusable nodes.

Patch Changes

• 3665d0b: The TypeScript return type of tabbable has been fixed: Was Array<Element> (an Element is technically not focusable), is now Array<HTMLElement | SVGElement> (which are both still/also Element instances).
• 8a25135: Fixed: Tabbable elements in fixed-position (position: fixed) containers should now be consistently found in supported browsers.
• 9544de2: Replace prepublishOnly script with prepare script. This has the added benefit of running automatically when installing the package from GitHub (as supported by NPM) where the published ./dist directory is not automatically included.
• 672f4a2: Add focusable() type definition.
• 2424c0f: Small improvements for improving tree-shakeability of this package. A missing #__PURE__ annotation has been added to allow dropping one of the top-level calls (if its result stays unused) and removed minification of the file referenced as package.json#module to avoid dropping the comments (including existing #__PURE__ annotations).

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.
