react实现同页面三级跳转路由布局

一级路由+布局组件：

//嵌套路由小案例 布局页面一级路由 import React from 'react' import {BrowserRouter as Router, Route, Link} from 'react-router-dom' //引入路由要用的组件 import Index from './Index' //二级路由 首页 import Video from './Video' // 二级路由 视频 import Workplace from './Workplace' //二级路由 职场 import './Router.css' //假设是后端获取的动态路由 function AppRouter(){ let routeConfig = [ {path:'https://www.jb51.net/',title:'博客首页',exact:true,component:Index}, {path:'/video',title:'视频教程',exact:false,component:Video}, {path:'/workplace',title:'职场技能',exact:false,component:Workplace}, ] return( <Router> <div className='mainDiv'> {/* 左侧导航部分 */} <div className='leftNav'> <h3>一级导航</h3> <ul> {/* 渲染动态路由 */} { routeConfig.map((item,index)=>{ return ( <li key={index}> <Link to={item.path}>{item.title}</Link> </li> ) }) } </ul> </div> {/* 右侧显示部分 */} <div className='rightMain'> { routeConfig.map((item,index)=>{ return ( <Route key={index} exact={item.exact} path={item.path} component={item.component} /> ) }) } </div> </div> </Router> ) } export default AppRouter

布局css：

body{ padding: 0px; margin: 0px; } .mainDiv{ display: flex; width: 100%; } .leftNav{ width: 16%; background-color: #c0c0c0; color:#333; font-size:24px; height: 1000px; padding: 20px; } .rightMain{ width: 84%; height:1000px; background-color: #fff; font-size:20px; }

二级路由 首页组件

//首页 二级路由 import React,{Component} from 'react' class Index extends Component { constructor(props) { super(props); this.state = { } } render() { return ( <div> <h2>我是首页</h2> </div> ); } } export default Index;

二级路由 视频组件

//视频页面 二级路由 import React from 'react' import { Route, Link} from 'react-router-dom' import ReactPage from './video/ReactPage' import Flutter from './video/Flutter' import Vue from './video/Vue' import './Video.css' function Video(){ return( <div> <div className='topNav'> <ul> <li><Link to='/video/reactpage/'>React教程</Link></li> <li><Link to='/video/Flutter/'>Flutter教程</Link></li> <li><Link to='/video/Vue/'>Vue教程</Link></li> </ul> </div> <div className='videoContent'> <div> <h3>视频教程</h3> <Route path='/video/reactpage/' component={ReactPage} /> <Route path='/video/Flutter/' component={Flutter} /> <Route path='/video/Vue/' component={Vue} /> </div> </div> </div> ) } export default Video

三级路由 视频 子页面

//三级路由 import React from 'react' function Flutter(){ return ( <h2> 我是Flutter </h2> ) } export default Flutter

//三级路由 import React from 'react' function ReactPage(){ return ( <h2> 我是react </h2> ) } export default ReactPage ..

其余二级三级页面类似
