Why ReactDOM.render () cannot render after the page jumps, and it has no effect
Page code after jump
import React,{Component}from "react";
import ReactDOM from "react-dom";
import { Flex, WhiteSpace,Button } from "antd-mobile";
import U98 from "../images/robotmanage/u98.png";
const Tip = ({ className = "", ...restProps }) => (
<span className={`${className} tip`} {...restProps}></span>
);
const FlexExample = () => (
<div className="flex-container">
<Flex justify="center">
<img src={U98} alt="u89"/>
</Flex>
<Flex justify="center">
<div><Tip />
</div>
</Flex>
<WhiteSpace size="lg" />
<Flex justify="center">
<Button></Button>
<Button></Button>
</Flex>
<WhiteSpace />
</div>
);
ReactDOM.render(<FlexExample />,document.getElementById("root"));
