如何在onSubmit调用的函数中使用状态？

import React, { useState } from 'react';

function MyForm() {
  const [formData, setFormData] = useState({});

  // 其他代码...

  return (
    // 表单组件...
  );
}

function MyForm() {
  const [formData, setFormData] = useState({});

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

  const handleSubmit = (event) => {
    event.preventDefault();
    // 在这里可以使用formData状态进行进一步处理
    console.log(formData);
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        name="username"
        value={formData.username || ''}
        onChange={handleInputChange}
      />
      <button type="submit">提交</button>
    </form>
  );
}
