👁 React-Focus-On


lock and loaded!
Build status npm downloads bundle size

The final solution for WAI ARIA compatible Modal Dialogs or any full-screen tasks:

Now you could focus on a single task.

This is basically the inert

Minimal size - no more than 2kb, maximal - no more that 6kb. See sidecar example for details.

Example

Code sandbox example - https://codesandbox.io/s/p3vjp8mzw7

import {FocusOn} from 'react-focus-on';

<FocusOn
 onClickOutside={callback}
 onEscapeKey={callback}
 shards={[externalRef]}
>
 content you should be "focused" on
</FocusOn>

API

FocusOn

FocusOn - the focus on component

  • enabled - controls behaviour
  • [shards] - a list of Refs to be considered as a part of the Lock. A way to properly handle portals or scattered lock.


  • [gapMode] - the way removed ScrollBar would be compensated - margin(default), or padding. See scroll-locky documentation to find the one you need.
  • [noIsolation] - disables aria-hidden isolation
  • [inert] - enables pointer-events isolation (☠️ dangerous, use to disable "parent scrollbars", refer to react-remove-scroll documentation)
  • [allowPinchZoom] - enables "pinch-n-zoom" behavior. By default it might be prevented, refer to react-remove-scroll documentation
  • [preventScrollOnFocus] - prevents a side effect of a programatic page scroll caused by focusing elements. Especially useful to address modal animations.

  • [onActivation] - on activation callback
  • [onDeactivation] - on deactivation callback

  • [onClickOutside] - on click outside of "focus" area. (actually on any event "outside")
  • [onEscapeKey] - on Esc key down (and not defaultPrevented)

Additional API

Exposed from React-Focus-Lock

  • AutoFocusInside - to mark autofocusable element
  • MoveFocusInside - to move focus inside a component on mount
  • InFocusGuard - to "guard" a shard node (place an invisible node before and after)

See react-focus-lock documentation for details.

Exposed from React-Remove-Scroll

  • classNames.fullWidth - "100%" width (will not change on scrollbar removal)
  • classNames.zeroRight - "0" right (will not change on scrollbar removal)

See react-remove-scroll for details.

PS: Version 1 used React-scroll-locky which was replaced by remove-scroll.
