vue项目之主页布局

1.背景

2.基本结构

 代码:

<template>
  <el-container class="home-container">
    <!-- 头部-->
    <el-header>Header</el-header>
    <el-container>
      <!--左侧-->

    methods: {
      // 退出登录
      logout() {
        window.sessionStorage.clear()
        this.$router.push("/login")
      }
    }
  }
</script>

<style lang="less" scoped>
  .home-container {
    height: 100%;
  }

  .el-header {
    background-color: #373d41;
    display: flex;
    justify-content: space-between;
    padding-left: 0;
    align-items: center;
    color: #fff;
    font-size: 20px;

    > div {
      display: flex;
      align-items: center;

      span {

    .el-menu {
      border-right: none;
    }
  }

    background-color: #eaedf1;
  }
</style>

3.头部

<template>
  <el-container class="home-container">
    <!-- 头部-->
    <el-header>
      <div>
        <img src="../assets/ldp.png">
        <span>后台管理系统</span>
      </div>
      <el-button type="info" @click="logout">退出</el-button>

      logout() {
        window.sessionStorage.clear()
        this.$router.push("/login")
      }
    }
  }
</script>

<style lang="less" scoped>
  .home-container {
    height: 100%;
  }

  .el-header {

4.左侧菜单

<template>
  <el-container class="home-container">
    <!-- 头部-->
    <el-header>
      <div>
        <img src="../assets/ldp.png">

      <el-button type="info" @click="logout">退出</el-button>
    </el-header>
    <el-container>
      <!--左侧-->
      <el-aside width="200px">
        <!--左侧菜单区域-->
        <el-menu
          default-active="2"
          class="el-menu-vertical-demo"
          background-color="#545c64"
          text-color="#fff"
          active-text-color="#ffd04b">
          <!-- 一级菜单-->

        </el-menu>
      </el-aside>
      <!--主题-->
      <el-main>Main</el-main>
    </el-container>
  </el-container>
</template>

<script>
  export default {
    name: "Home",
    methods: {
      // 退出登录
      logout() {
        window.sessionStorage.clear()
        this.$router.push("/login")
      }
    }
  }
</script>

    .el-menu {
      border-right: none;
    }
  }

  .el-main {
    background-color: #eaedf1;
  }
</style>

5.请求统一配置token

// 设置请求token
axios.interceptors.request.use(config => {
  // console.log(config)
  config.headers.Authorization = window.sessionStorage.getItem('token')
  // 在最后必须 return config
  return config
})

6.菜单遍历

<template>
  <el-container class="home-container">
    <!-- 头部-->
    <el-header>
      <div>
        <img src="../assets/ldp.png">

7.只展开一个菜单

 

8.折叠菜单

 

 代码:

<template>
  <el-container class="home-container">
    <!-- 头部-->
    <el-header>
      <div>
        <img src="../assets/ldp.png">

      </div>
      <el-button type="info" @click="logout">退出</el-button>
    </el-header>
    <el-container>
      <!--左侧-->
      <el-aside :width="isCollapse?'60px':'200px'">
        <div class="toggle-button" @click="toggleBtn"><<>></div>
        <!--左侧菜单区域-->
        <el-menu
          default-active="2"
          class="el-menu-vertical-demo"
          background-color="#545c64"
          text-color="#fff"
          active-text-color="#ffd04b" unique-opened :collapse="isCollapse" :collapse-transition="false">
          <!-- 一级菜单-->
          <el-submenu v-for=" item in menuList" :index="item.id+''" :key="item.id">
            <!-- 一级菜单模板区-->
            <template slot="title">
              <i :class="iconObj[item.id]"></i>

        this.menuList = result.data
      }
    }
  }
</script>

<style lang="less" scoped>
  .home-container {

</style>

9.主页里的首页实现

1.编写主页

2.配置路由

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import Home from '@/components/Home'
import Welcome from '@/components/Welcome'

Vue.use(Router)
const routerChildren = [
  {
    path: '/welcome',
    name: 'Welcome',
    component: Welcome
  }
]
const router = new Router({
  routes: [
    {
      path: "/",
      redirect: "/login"
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    }
    ,
    {
      path: '/home',
      name: 'Home',
      redirect: "/welcome",
      component: Home,
      children: routerChildren
    }
  ]
})
router.beforeEach((to, from, next) => {
  // to 将要访问的路径
  // from 从哪里跳转来的
  // next 放行

  // 判断是不是登录登录,登录路径直接放行
  if (to.path == '/login') {
    next()
    return
  }
  // 获取token,看是否有token,有token放行
  const token = window.sessionStorage.getItem("token")
  if (!token) {
    next('/login')
    return;
  }
  // 放行
  next();
})
export default router

3.设置路由占位

<!--主题-->
<el-main>
  <!-- 路由占位符 -->
  <router-view></router-view>
</el-main>

10.路由到各个子菜单

1.开启子菜单路由

2.index设置路由地址

3.编写各个路由组件

4.配置路由地址

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import Home from '@/components/Home'
import Welcome from '@/components/Welcome'
import User from '@/components/user/User'

Vue.use(Router)
const routerChildren = [
  {
    path: '/welcome',
    name: 'Welcome',
    component: Welcome
  },
  {
    path: '/users',
    name: 'User',
    component: User
  }
]
const router = new Router({
  routes: [
    {
      path: "/",
      redirect: "/login"
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    }
    ,
    {
      path: '/home',
      name: 'Home',
      redirect: "/welcome",
      component: Home,
      children: routerChildren
    }
  ]
})
router.beforeEach((to, from, next) => {
  // to 将要访问的路径
  // from 从哪里跳转来的
  // next 放行

  // 判断是不是登录登录,登录路径直接放行
  if (to.path == '/login') {
    next()
    return
  }
  // 获取token,看是否有token,有token放行
  const token = window.sessionStorage.getItem("token")
  if (!token) {
    next('/login')
    return;
  }
  // 放行
  next();
})
export default router

11.子路由激活状态设置 

 代码:
