使用挂钩检测React组件外部的单击

import React, { useRef, useEffect } from 'react';

const useOutsideClick = (ref, callback) => {
  const handleClick = (event) => {
    if (ref.current && !ref.current.contains(event.target)) {
      callback();
    }
  };

  useEffect(() => {
    document.addEventListener('click', handleClick);

    return () => {
      document.removeEventListener('click', handleClick);
    };
  }, [ref, callback]);
};

const MyComponent = () => {
  const ref = useRef(null);

  const handleOutsideClick = () => {
    // 处理组件外部的单击事件
  };

  useOutsideClick(ref, handleOutsideClick);

  return <div ref={ref}>My Component</div>;
};
