实现效果图

1、项目中的图标使用的是element-ui框架中的图标，如果需要引入可以看我写的上一篇文章。

2、首先配置路由

我初始化项目的时候初始化了路由，所以打开router/index.js文件进行修改配置

router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/components/Home'
import Game from '@/components/Game'
import Bbs from '@/components/Bbs'
import Me from '@/components/Me'
import Nba from '@/components/Nba'
import Recommend from '@/components/Recommend'

Vue.use(Router)

export default new Router({
 mode: 'history',
 linkActiveClass: 'active',
 routes: [
 { path: '/', redirect: '/home' }, // 重定向到 home
 {
  path: '/home',
  name: 'Home',
  component: Home,
  // children path中"/home/"可以省略
  children: [
  {
   path: '/',     // 子路由重定向
   redirect: 'recommend'
  },
  {
   path: 'recommend',
   name: 'recommend',
   component: Recommend
  },
  {
   path: 'nba',
   name: 'nba',
   component: Nba
  },
  {
   path: 'video',
   name: 'video',
   component: Nba
  },
  {
   path: 'entertain',
   name: 'entertain',
   component: Nba
  }
  ]
 },
 {
  path: '/game',
  name: 'Game',
  component: Game
 }, {
  path: '/bbs',
  name: 'Bbs',
  component: Bbs
 }, {
  path: '/me',
  name: 'Me',
  component: Me
 }
 ]
})

app.vue

底部导航封装为TabBar组件，在app.vue中引入

<template>
 <div id="app">
 <div :class="{router: true}">
  <router-view/>
 </div>
 <!-- 底部导航组件 -->
 <div :class="{tabbar: true}">
  <tab-bar></tab-bar>
 </div>
 </div>
</template>
<script>
import TabBar from './components/Tabs'
export default {
 name: 'App',
 components: {
 // 底部导航组件
 TabBar
 }
}
</script>
<style scoped>
 #app {
 width: 100%;
 height: 100%;
 display: flex;
 flex-direction: column;
 }
 .router {
 flex: 1;
 padding: 10pt;
 }
 .tabbar {
 height: 30pt;
 padding: 10pt 0;
 border-top: 1pt solid #e6e6e6;
 background: #fbfbfb;
 }
</style>

Tabs.vue

<template>
 <div id="tabs">
 <div class="home">
  <!-- 点击其他tab页，再次点击home的时候，路由重定向到了recommend，注意写法 to="/home/" -->
  <router-link to="/home/" tag="div">
   <div><i class="el-icon-s-home"></i></div>
  <div>首页</div>
  </router-link>
 </div>
 <div class="game">
  <router-link :to="{name: 'Game'}" tag="div">
   <div><i class="el-icon-s-goods"></i></div>
  <div>比赛</div>
  </router-link>
 </div>
 <div class="bbs">
  <router-link :to="{name: 'Bbs'}" tag="div">
   <div><i class="el-icon-share"></i></div>
  <div>社区</div>
  </router-link>
 </div>
 <div class="me">
  <router-link :to="{name: 'Me'}" tag="div">
   <div><i class="el-icon-s-custom"></i></div>
  <div>我</div>
  </router-link>
 </div>
 </div>
</template>
<script>
export default {
 name: 'TabBar'
}
</script>
<style scoped>
 #tabs {
  width: 100%;
  display: flex;
  flex-direction: row;
  justify-content: space-around;
  align-items: center;
  text-align: center;
  color: #b5b5b5;
 }
 #tabs i {
  font-size: 18pt;
 }
 .active {
  color: #468dcc;
 }
</style>

这样就添加了底部导航，然后我们配置home界面，home界面中有二级导航，而且在首页的二级导航选中的时候，需要高亮显示”首页“tab页

Home.vue

<template>
 <div id="home">
 <div :class="{topbar: true}">
  <router-link :to="{name: 'recommend'}" tag="div">推荐</router-link>
  <router-link :to="{name: 'nba'}" tag="div">篮球(NBA)</router-link>
  <router-link :to="{name: 'video'}" tag="div">视频</router-link>
  <router-link :to="{name: 'entertain'}" tag="div">影视娱乐</router-link>
 </div>
 <div :class="{tabInfo: true}">
  <router-view/>
 </div>
 </div>
</template>
<script>
export default {
 name: 'Home',
 data () {
 return {
  name: 'home'
 }
 }
}
</script>
<style scoped>
 #home {
 display: flex;
 flex-direction: column;
 text-align: left;
 height: 100%;
 }
 .topbar {
 height: 26pt;
 font-size: 12pt;
 color: #343434;
 background: #fbfbfb;
 border-bottom: 1pt solid #e6e6e6;
 margin-bottom: 10pt;
 display: flex;
 flex-direction: row;
 }
 .topbar div {
 margin: 0 5pt;
 }
 .topbar span {
 padding-bottom: 11pt;
 }
 .active {
 color: #468dcc;
 border-bottom: 1pt solid #468dcc;
 font-weight: bold;
 }
 .tabInfo {
 flex: 1;
 }
</style>
