使用json数据的reactjs中的动态表单验证

import React, { Component } from 'react';

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

  // 其他代码...
}

handleChange = (e) => {
  const { name, value } = e.target;
  this.setState(prevState => ({
    formData: {
      ...prevState.formData,
      [name]: value
    }
  }));
  
  // 动态表单验证
  this.validateField(name, value);
}

validateField = (fieldName, value) => {
  let errors = { ...this.state.errors };

  // 根据字段名称进行验证
  switch (fieldName) {
    case 'name':
      // 进行姓名验证逻辑
      break;
    case 'email':
      // 进行邮箱验证逻辑
      break;
    case 'password':
      // 进行密码验证逻辑
      break;
    default:
      break;
  }

  this.setState({ errors });
}

render() {
  const { formData, errors } = this.state;

  return (
    <form>
      <input
        type="text"
        name="name"
        value={formData.name}
        onChange={this.handleChange}
      />
      {errors.name && <span>{errors.name}</span>}
      
      <input
        type="email"
        name="email"
        value={formData.email}
        onChange={this.handleChange}
      />
      {errors.email && <span>{errors.email}</span>}
      
      <input
        type="password"
        name="password"
        value={formData.password}
        onChange={this.handleChange}
      />
      {errors.password && <span>{errors.password}</span>}
      
      <button type="submit">提交</button>
    </form>
  );
}
