react实现同页面三级跳转路由布局

//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:'/',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(
    
      

        {/* 左侧导航部分 */}
        

          
一级导航
          

            {/* 渲染动态路由 */}
            {
              routeConfig.map((item,index)=>{
                return (
                  

                    {item.title}
                  
                )
              })
            }
          
        
        {/* 右侧显示部分 */}
        

          {
           routeConfig.map((item,index)=>{
            return (
              
            )
          }) 
          }
        
      
    
  )
}
 
export default AppRouter

//首页 二级路由

    super(props);
    this.state = { }
  }

我是首页
    
 
    );
  }
