如何在React中从表单中获取数据

import React, { Component } from 'react';

class MyForm extends Component {
  constructor(props) {
    super(props);
    this.state = {
      name: '',
      email: '',
      message: ''
    };
  }

  handleInputChange = (event) => {
    const { name, value } = event.target;
    this.setState({ [name]: value });
  }

  handleSubmit = (event) => {
    event.preventDefault();
    const { name, email, message } = this.state;
    // 在这里可以对表单数据进行处理或发送到服务器
    console.log('Name:', name);
    console.log('Email:', email);
    console.log('Message:', message);
  }

  render() {
    const { name, email, message } = this.state;
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Name:
          <input type="text" name="name" value={name} onChange={this.handleInputChange} />
        </label>
        <br />
        <label>
          Email:
          <input type="email" name="email" value={email} onChange={this.handleInputChange} />
        </label>
        <br />
        <label>
          Message:
          <textarea name="message" value={message} onChange={this.handleInputChange} />
        </label>
        <br />
        <button type="submit">Submit</button>
      </form>
    );
  }
}

export default MyForm;
