useFocusReturn

The useFocusReturn hook in React Refocus remembers the previously focused element and restores focus to it after certain interactions. This hook is particularly useful in scenarios where focus management is crucial for user experience and accessibility, such as closing modals, navigating through forms, or switching between UI components.

Syntax

useFocusReturn(): void;

Example

import React, { useState } from 'react';
import { useFocusReturn } from 'react-refocus/hooks/useFocusReturn';

const ExampleComponent = () => {
  const [showModal, setShowModal] = useState(false);

  useFocusReturn();

  return (
    <div>
      <button onClick={() => setShowModal(true)}>Open Modal</button>
      {showModal && (
        <div>
          <h2>Modal Title</h2>
          <p>Modal Content</p>
          <button onClick={() => setShowModal(false)}>Close Modal</button>
        </div>
      )}
    </div>
  );
};

export default ExampleComponent;

Usage

The useFocusReturn hook is particularly useful in forms, dialogs, and other complex UIs where you can return the focus to the previously focused element after closing dialogs, modals etc.

Accessibility Note

Managing focus correctly is crucial for accessibility. The useFocusReturn hook helps improve usability by ensuring that users are returned to their previous position in the UI, reducing confusion and improving the overall experience for keyboard and screen reader users.
