React基于JSON的表单使用setstate

import React, { Component } from 'react';

class MyForm extends Component {
  constructor(props) {
    super(props);
    this.state = {
      formData: {
        name: '',
        email: '',
        password: ''
      }
    };
  }

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

  handleSubmit = (event) => {
    event.preventDefault();
    // 可以在这里获取最终的表单数据并进行处理
    console.log(this.state.formData);
  }

  render() {
    const { name, email, password } = this.state.formData;

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

export default MyForm;
