在使用t.form的原生react上使用setState更新数据

import React, { useState } from 'react';

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

  // 其他组件代码...

  return (
    // 表单组件代码...
  );
};

export default MyForm;

import React, { useState } from 'react';

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

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

  return (
    <form>
      <input
        type="text"
        name="username"
        value={formData.username || ''}
        onChange={handleInputChange}
      />
      {/* 其他表单元素... */}
    </form>
  );
};

export default MyForm;
