如何使用React创建表单发布？

npx create-react-app my-form-app

cd my-form-app

import React, { useState } from 'react';

function Form() {
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    message: ''
  });

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

  const handleSubmit = (e) => {
    e.preventDefault();
    // 在这里处理表单提交的逻辑
  };

  return (
    <form onSubmit={handleSubmit}>
      <label>
        Name:
        <input type="text" name="name" value={formData.name} onChange={handleChange} />
      </label>
      <label>
        Email:
        <input type="email" name="email" value={formData.email} onChange={handleChange} />
      </label>
      <label>
        Message:
        <textarea name="message" value={formData.message} onChange={handleChange} />
      </label>
      <button type="submit">Submit</button>
    </form>
  );
}

export default Form;

import React from 'react';
import Form from './Form';

function App() {
  return (
    <div className="App">
      <Form />
    </div>
  );
}

export default App;

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './index.css';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

npm start
