vue2.0+element搭建后台系统（3）

vue2.0+element搭建后台系统（3）接入element-ui

准备

element-ui官网:https://element.faas.ele.me/#/zh-CN/component/installation

开始

执行以下命令：

npm i element-ui -S

完成后，可以看到版本：

现在接着改造项目,首先在入口文件引入element。在main.js头部import。

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

Vue.use(ElementUI)
Vue.config.productionTip = false

router.beforeEach((to, from, next) => {
  if (to.path === '/login') {
    sessionStorage.removeItem('user')
  }
  let user = JSON.parse(sessionStorage.getItem('user'))
  if (!user && to.path !== '/login') {
    next({
      path: '/login'
    })
  } else {
    next()
  }
})

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

改造首页

首先改造首页，传统的后台管理系统应该是一个上下左右的布局模式，既然有了想法，开干。
创建文件：
src/components/home.vue

<template>
  <div>
    <el-container>
      <el-header>
        <el-menu :default-active="activeIndex" class="el-menu-demo" mode="horizontal"
                 background-color="#545c64" text-color="#fff" active-text-color="#ffd04b">
          <el-menu-item index="1">处理中心</el-menu-item>
          <el-menu-item index="3">消息中心</el-menu-item>
          <el-menu-item index="4">订单管理</el-menu-item>
        </el-menu>
      </el-header>
      <el-container>
        <el-aside width="200px">
          <el-col>
            <el-menu
              default-active="2"
              class="el-menu-vertical-demo"
              @open="handleOpen"
              @close="handleClose">
              <el-submenu index="1">
                <template slot="title">
                  <i class="el-icon-location"></i>
                  <span>导航一</span>
                </template>
                <el-menu-item index="1-1">选项1</el-menu-item>
                <el-menu-item index="1-2">选项2</el-menu-item>
                <el-menu-item index="1-3">选项3</el-menu-item>
              </el-submenu>
              <el-menu-item index="2">
                <i class="el-icon-menu"></i>
                <span slot="title">导航二</span>
              </el-menu-item>
              <el-menu-item index="3" disabled>
                <i class="el-icon-document"></i>
                <span slot="title">导航三</span>
              </el-menu-item>
              <el-menu-item index="4">
                <i class="el-icon-setting"></i>
                <span slot="title">导航四</span>
              </el-menu-item>
            </el-menu>
          </el-col>
        </el-aside>
        <el-container>
          <el-main>Main</el-main>
          <el-footer>Footer</el-footer>
        </el-container>
      </el-container>
    </el-container>
  </div>
</template>

<script>
export default {
  name: 'home',
  data () {
    return {activeIndex: '1'}
  },
  methods: {
    handleOpen (key, keyPath) {
      console.log(key, keyPath)
    },
    handleClose (key, keyPath) {
      console.log(key, keyPath)
    }
  }
}
</script>

<style scoped>
  .el-header {
    padding: 0;
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
    -ms-flex-negative: 0;
    flex-shrink: 0;
  }

  .el-header, .el-footer {
    background-color: #B3C0D1;
    color: #333;
    text-align: center;
    line-height: 60px;
  }

  .el-aside {
    background-color: #D3DCE6;
    color: #333;
    text-align: center;
    line-height: 200px;
    height: calc(100vh - 76px);
  }

  .el-main {
    background-color: #E9EEF3;
    color: #333;
    text-align: center;
    line-height: 160px;
  }

  /*body > .el-container {*/
    /*margin-bottom: 40px;*/
  /*}*/

  /*.el-container:nth-child(5) .el-aside,*/
  /*.el-container:nth-child(6) .el-aside {*/
    /*line-height: 260px;*/
  /*}*/

  /*.el-container:nth-child(7) .el-aside {*/
    /*line-height: 320px;*/
  /*}*/
</style>

更改路由：
src/router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import home from '@/components/home'

import login from '@/components/login'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/login',
      name: 'login',
      component: login
    },
    {
      path: '/',
      name: 'home',
      component: home
    }
  ]
})
