在React中创建保存数据的表单

import React, { useState } from 'react';

const FormComponent = () => {
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    message: ''
  });
  const [successMessage, setSuccessMessage] = useState('');
  const [errorMessage, setErrorMessage] = useState('');

  const handleChange = (e) => {
    setFormData({
      ...formData,
      [e.target.name]: e.target.value
    });
  };

  const handleSubmit = (e) => {
    e.preventDefault();

    // 发送表单数据到后端服务器进行保存
    fetch('/api/saveFormData', {
      method: 'POST',
      body: JSON.stringify(formData)
    })
      .then(response => response.json())
      .then(data => {
        if (data.success) {
          setSuccessMessage('表单提交成功！');
          setErrorMessage('');
        } else {
          setSuccessMessage('');
          setErrorMessage('表单提交失败，请重试！');
        }
      })
      .catch(error => {
        setSuccessMessage('');
        setErrorMessage('表单提交失败，请重试！');
      });
  };

  return (
    <div>
      {successMessage && <div>{successMessage}</div>}
      {errorMessage && <div>{errorMessage}</div>}
      <form onSubmit={handleSubmit}>
        <label>
          姓名：
          <input type="text" name="name" value={formData.name} onChange={handleChange} />
        </label>
        <br />
        <label>
          邮箱：
          <input type="email" name="email" value={formData.email} onChange={handleChange} />
        </label>
        <br />
        <label>
          消息：
          <textarea name="message" value={formData.message} onChange={handleChange} />
        </label>
        <br />
        <button type="submit">提交</button>
      </form>
    </div>
  );
};

export default FormComponent;
