使用react将表单作为功能组件

import React, { useState } from 'react';

function LoginForm() {
  const [formData, setFormData] = useState({
    username: '',
    password: ''
  });

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

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log('Form Data:', formData);
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="username">Username:</label>
        <input
          type="text"
          id="username"
          name="username"
          value={formData.username}
          onChange={handleChange}
        />
      </div>
      <div>
        <label htmlFor="password">Password:</label>
        <input
          type="password"
          id="password"
          name="password"
          value={formData.password}
          onChange={handleChange}
        />
      </div>
      <button type="submit">Submit</button>
    </form>
  );
}

export default LoginForm;
