React和TypeScript中的Form与干式更改处理

import React, { useState } from 'react';

interface FormData {
  username: string;
  password: string;
}

const FormComponent: React.FC = () => {
  const [formData, setFormData] = useState<FormData>({
    username: '',
    password: '',
  });

  const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const { name, value } = e.target;
    setFormData((prevFormData) => ({
      ...prevFormData,
      [name]: value,
    }));
  };

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    // 处理表单提交逻辑
  };

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

export default FormComponent;
