检查div值并更新React中的类

import React, { useState } from 'react';

const MyComponent = () => {
  const [divValue, setDivValue] = useState('');
  const [divClass, setDivClass] = useState('');

  // 其他组件代码...

  return (
    <div className={divClass}>{divValue}</div>
  );
};

export default MyComponent;

const checkAndUpdateDiv = () => {
  // 检查div的值
  if (divValue === 'someValue') {
    setDivClass('classA');
  } else if (divValue === 'anotherValue') {
    setDivClass('classB');
  } else {
    setDivClass('classC');
  }
};

const handleInputChange = (event) => {
  const value = event.target.value;
  setDivValue(value);

  // 在div值变化时调用检查和更新函数
  checkAndUpdateDiv();
};
