我是reactJS的新手,当有人留下空白文件时,我想显示错误消息。表单已经通过验证,但是无法显示错误消息。我从(ant-design复制了此表单代码,我将共享它的链接以查看原始表单,并且可以正常工作,但是在我的表单中,错误消息不起作用。 原始表单链接Form Link

我的表格代码

import React from 'react';
import styled from 'styled-components';
import 'antd/dist/antd.css';
import Input from 'antd/lib/input';

const FormCard = styled.div`
  max-width: 100%;
  overflow: hidden;
  transition: all 0.3s cubic-bezier(0.41, 0.094, 0.54, 0.07) 0s;
  margin-top: 30px;
`;

const FormItem = styled.div`
  font-family: 'Chinese Quote', -apple-system, BlinkMacSystemFont, 'Segoe UI',
    'PingFang SC', 'Hiragino Sans GB', 'Microsoft YaHei', 'Helvetica Neue',
    Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji',
    'Segoe UI Symbol';
  font-size: 14px;
  font-variant: tabular-nums;
  color: rgba(0, 0, 0, 0.65);
  -webkit-box-sizing: border-box;
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  list-style: none;
  margin-bottom: 18px;
  vertical-align: top;

class RegisterStepOne extends React.Component {

如果使用的是Ant设计组件,则应先导入

import { Form,  Input} from 'antd';
const FormItem = Form.Item;

也请替换

export default RegisterStepOne;

const RegisterStepOne = Form.create()(RegisterStepOne);

ReactDOM.render(<RegisterStepOne />, mountNode);
