get-focusables
Get focusable or tabbable elements within a DOM node
Versions
The package includes versions for ES6+ and ES5, both as an ESM module (browser-compatible) and a CJS module (npm-compatible).
Here's the included file variants:
| | CJS | ESM | importing |
| --- | -------- | --------- | -------------------------------------------------------- |
| ES6 | index.js | index.mjs | const getFocusableElements = require('get-focusables')
|
| ES5 | es5.js | es5.mjs | import getFocusableElements from 'get-focusables'
|
Each version gives you the getFocusableElements function.
get-focusables
is written in ES6 syntax and packaged node-style.
It is converted to ES5/ESM for wider distribution.
The default is therefore the ES6 CJS variant index.js
.
NOTE In order to get a non-default version, you will need to tell your bundler to use
index.mjs
/es5.js
/es5.mjs
instead ofindex.js
. Forwebpack
, that's{ resolve: { alias: { 'get-focusables': 'get-focusables/es5.mjs } } }'

boolean Restrict to tabbable elements (optional, defaulttrue
)

Parameters
context
Element The DOM Element in which to look for focusable elements (optional, defaultdocument
)tabbable
boolean Restrict to tabbable elements (optional, defaulttrue
)

NodeListDummy
The NodeListDummy is an object with a length property of 0.
This ensures that the result of getFocusableElements
can always be used and checked for length.
That makes checks for a truthy/falsy return value unnecessary.
Type: Object
Properties
length
number always 0
