React输入字段在提交后不为空

import React, { useState } from 'react';

function MyForm() {
  const [inputValue, setInputValue] = useState('');

  const handleSubmit = (e) => {
    e.preventDefault();
    if (inputValue.trim() !== '') {
      // 执行提交表单的操作
    } else {
      // 输入字段为空，给出错误提示或其他处理
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        value={inputValue}
        onChange={(e) => setInputValue(e.target.value)}
      />
      <button type="submit">提交</button>
    </form>
  );
}

export default MyForm;
