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。

export default RegisterStepOne;
答案 0 :(得分:3)
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;
与
const RegisterStepOne = Form.create()(RegisterStepOne);
ReactDOM.render(<RegisterStepOne />, mountNode);
