17. 基于Vue+Element+nodeJs+Express+MySql后台管理系统-前端主页面

这期开始主页面的编写，在src\views目录下创建主页面Home.vue，主要是管理系统页面布局，头部和左侧导航栏。

一、Home.vue 页面 

1.1 Home.vue 页面html部分：

<template>
  <el-container class="home-wrap">
    <!-- header start -->
    <el-header class="flex">
      <div class="logo flex-item"><i class="el-icon-date"></i> 工作周报</div>
      <div class="user-info">
        <el-dropdown @command="handleCommand">
          <el-button type="primary">
            <i class="el-icon-user-solid el-icon--left"></i>{{userInfo.name}}
          </el-button>
          <el-dropdown-menu slot="dropdown">
            <el-dropdown-item command="loginOut">退出</el-dropdown-item>
          </el-dropdown-menu>
        </el-dropdown>
      </div>
    </el-header>
    <!-- header end -->
    <div class="container-wrap">
      <!-- aside-nav start -->
      <div class="aside-wrap">
        <el-menu
          :default-active="activePath"
          background-color="#283643"
          text-color="#fff"
          active-text-color="#1CC09F"
          router>
          <el-menu-item v-for="item in menuList" :key="item.url" :index="item.url"
          @click="handleSelect(item.url)">
            <i :class="item.icon"></i>
            <span slot="title">{{item.name}}</span>
          </el-menu-item>
        </el-menu>
      </div>
      <!-- aside-nav end -->

      <!-- main start -->
      <div class="main-wrap">
        <router-view/>
      </div>
      <!-- main end -->

    </div>
  </el-container>
</template>
           

1.2 Home.vue 页面js部分： 

<script>
import { userLogout } from '@/config/interface'
export default {
  data () {
    return {
      menuList: this.$store.state.menuList,
      activePath: null,
      reqFlag: {
        logout: true
      }
    }
  },
  components: {

  },
  computed: {
    userInfo: function () {
      let userInfo = this.$store.state.userInfo
      return userInfo
    }
  },
  watch: {
    '$route': function (to, from) {
      this.activePath = to.meta.pagePath
    }
  },
  created () {
    this.activePath = this.$route.meta.pagePath
  },
  methods: {
    handleCommand (command) {
      if (command == 'loginOut') {
        this.loginOut()
      }
    },
    // 登出
    loginOut () {
      const url = userLogout
      if (this.reqFlag.logout) {
        this.reqFlag.logout = false
        let params = {}
        this.$http(url, params)
        .then(res => {
          if (res.code == 1) {
            localStorage.clear()
            this.$store.dispatch('saveUserInfo', {})
            this.$common.toast('登出成功', 'success', false)
            this.$router.replace({ path: '/' })
          }
          this.reqFlag.logout = true
        })
      }
    },
    // 解决element导航中，当前导航路由标识和当前路由一致时，点击当前导航，页面不刷新问题
    handleSelect (indexPath) {
      if (indexPath == this.$route.path) {
        this.$common.shallowRefresh(this.$route.name)
      }
    }
  }
}
</script>
           

1.3 Home.vue 页面展示：
