import React, { useState } from 'react';

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

  const handleSubmit = (event) => {
    event.preventDefault();
    // 在这里可以进行表单验证和数据处理
    console.log(formData);
  };

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

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