如何在选取器中解决react原生空值？

import React, { useState } from 'react';

const MyComponent = () => {
  const [selectedValue, setSelectedValue] = useState('');

  const handleSelectChange = (event) => {
    setSelectedValue(event.target.value);
  };

  const handleSubmit = () => {
    if (selectedValue === '') {
      // 处理空值情况
      console.log('请选择一个选项');
      return;
    }

    // 执行其他操作
    console.log('选中的值：', selectedValue);
  };

  return (
    <div>
      <select value={selectedValue} onChange={handleSelectChange}>
        <option value="">请选择</option>
        <option value="option1">选项1</option>
        <option value="option2">选项2</option>
        <option value="option3">选项3</option>
      </select>
      <button onClick={handleSubmit}>提交</button>
    </div>
  );
};

export default MyComponent;
