<template>
  <div>User</div>
</template>

<script>
export default {
  name: 'UserPage'
}
</script>

三、功能实现

3.1. 配置一二级路由

一级路由包括首页（Layout）和面经详情（ArticleDetail），子路由通过children属性来实现：

import ArticleDetail from '@/views/ArticleDetail.vue';
import Layout from '@/views/Layout.vue';
import Article from '@/views/Article.vue';
import Collect from '@/views/Collect.vue';
import Like from '@/views/Like.vue';
import User from '@/views/User.vue';
import Vue from 'vue'
import VueRouter from "vue-router";
Vue.use(VueRouter)

const router = new VueRouter({
  routes: [
    { path: '/', component: Layout,
      // 通过children配置项，可以配置嵌套子路由
      // 1.在children配置项中配置规则
      // 2.准备二级路由出口 
      children: [
        { path: '/article', component: Article },
        { path: '/collect', component: Collect },
        { path: '/like', component: Like },
        { path: '/user', component: User }
      ]
    },
    { path: '/detail', component: ArticleDetail }
  ]
})

export default router

3.2. 配置路由出口/链接/高亮显示

<template>
  <div class="h5-wrapper">
    <div class="content">
      <!-- 配置二级路由出口，匹配到的二级路由组件就会在此展示 -->
      <router-view></router-view>
    </div>
    <nav class="tabbar">
      <!-- 
        导航高亮显示效果
        1. 将a标签，替换成router-link 并将 a标签 href属性 改成 to
        2. 结合高亮类名实现高亮效果 router-link-active
      -->
      <router-link to="/article">面经</router-link>
      <router-link to="/collect">收藏</router-link>
      <router-link to="/like">喜欢</router-link>
      <router-link to="/user">我的</router-link>
    </nav>
  </div>
</template>

<script>
export default {
  name: "LayoutPage",
}
</script>

<style>
body {
  margin: 0;
  padding: 0;
}
</style>
<style lang="less" scoped>
.h5-wrapper {
  .content {
    margin-bottom: 51px;
  }
  .tabbar {
    position: fixed;
    left: 0;
    bottom: 0;
    width: 100%;
    height: 50px;
    line-height: 50px;
    text-align: center;
    display: flex;
    background: #fff;
    border-top: 1px solid #e4e4e4;
    a {
      flex: 1;
      text-decoration: none;
      font-size: 14px;
      color: #333;
      -webkit-tap-highlight-color: transparent;
    }
    // 自定义 Vue路由高亮类名 的颜色
    a.router-link-active {
      color: orange;
    }
  }
}
</style>
