React配置子路由的實現

1、元件First.js下有子元件：
import Admin from './Admin' import FormCom from './FormCom' import One from './One' import ButtonCom from './ButtonCom' import MenuCom from './MenuCom' import StepsCom from './StepsCom' import TabsCom from './TabsCom' import TableCom from './TableCom' import MessageCom from './MessageCom' import NotificationCom from './NotificationCom' import ProgressCom from './ProgressCom' import SpinCom from './SpinCom' import BadgeCom from './BadgeCom'
First.js完整程式碼如下：
import React from 'react'
import { Layout,Menu } from 'antd';
import { UserOutlined,LaptopOutlined,NotificationOutlined } from '@ant-design/icons';
import { HashRouter,Route,Link } from 'react-router-dom'
import Admin from './Admin'
import FormCom from './FormCom'
import One from './One'
import ButtonCom from './ButtonCom'
import MenuCom from './MenuCom'
import StepsCom from './StepsCom'
import TabsCom from './TabsCom'
import TableCom from './TableCom'
import Messa
其中
${this.props.match.path}
是關鍵。
2、假設還有一個登入元件Login.js，程式碼如下：
import React from 'react'
import { Button } from 'antd';
export default class Login extends React.Component {
constructor() {
super();
}
redirectHandle = () => {
console.log("aaa");
this.props.history.push("/home");
}
render() {
return (<Button type="primary" onClick={()=>this.redirectHandle()}>Primary Button</Button>)
}
}
假設React專案用的是React腳手架搭建，則在src目錄下的App.js檔案中設定路由：
render() {
return (<HashRouter>
<Switch>
<Route exact={true} path="/login" component={Login} />
<Route path="/home" component={First} />
<Redirect to='/login' /> {/*/log程式設計客棧in和/home之外的路由直接跳轉到/login*/}
</Switch>
</HashRouter>)
}
App.js完整程式碼如下：
import React from 'react';
import { notification } from 'antd'
import { HashRouter,Switch,Redirect } from 'react-router-dom';
import First from './First';
import Login from './Login';
import './App.css';
class App extends React.Component {
constructor() {
super();
this.openNotificationWithIcon = type => {
notification[type]({
message: 'Notification Title',description:
'This is the content of the notification. This is the content of the notification. This is the content of the notification.',});
}
}
clickHandle() {
console.log("clicked!!!");
}
render() {
return (<HashRouter>
<Switch>
<Route exact={true} path="/login" component={Login} /> {/**exact 防止混路由混合 如：輸入127.xx.xx.xx/home 中有/login頁面*/}
<Route path="/home" component={First} />
<Redirect to='/login' />
</Switch>
</HashRouter>)
}
}
export default App;
專案目錄結構如下：
專案預覽效果如下：
