前端搭建

Vue router 来动态构建左侧菜单

• 导航1
  • 页面1
  • 页面2
• 导航2
  • 页面3
  • 页面4
• 导航3
  • 页面5
  • 页面6

在views目录下创建四个页面

PageOne.vue

<template>
  <h1>这是页面1</h1>
</template>
<script>
export default {
  name: "PageOne",
};
</script>
<style scoped></style>

配置路由:router/index.js

import Vue from 'vue'
import VueRouter from 'vue-router'
import Book from '../views/Book.vue'
import PageOne from '@/views/PageOne.vue'
import PageTwo from '@/views/PageTwo.vue'
import PageThree from '@/views/PageThree.vue'
import PageFour from '@/views/PageFour.vue'
import Nav from '@/views/Nav.vue'
import APP from '../App'
Vue.use(VueRouter)

const routes = [
  {
    path: "/nav1",
    name: "导航1",
    component: Nav,
    children: [
      {
        path: "/nav1/pageOne",
        name: "页面1",
        component: PageOne
      },
      {
        path: "/nav1/pageTwo",
        name: "页面2",
        component: PageTwo
      }
    ]
  },
  {
    path: "/nav2",
    name: "导航2",
    component: Nav,
    children: [
      {
        path: "/nav2/pageThree",
        name: "页面3",
        component: PageThree
      },
      {
        path: "/nav2/pageFour",
        name: "页面4",
        component: PageFour
      }
    ]
  }
]

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router
