本文实例为大家分享了react实现同页面三级跳转路由布局的具体代码，供大家参考，具体内容如下

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:'/',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',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
..
