從零搭建自己的Vue管理端框架（四）

Hello大家好，本章我們建立Home頁側邊欄，中間顯示區域 。有問題可以聯絡我mr_beany@163.com。另求各路大神指點，感謝

一：建立新頁面用於跳轉

建立static→css→common.css

h2{
  margin: 0;
}
li {
  list-style: none
}
.disFlex {
  display: -webkit-box;
  display: -moz-box;
  display: -webkit-flex;
  display: -moz-flex;
  display: -ms-flexbox;
  display: flex;
}
.padding{
  padding: 20px;
}


::-webkit-scrollbar
{
  width: 10px;
  height: 10px;
  background-color: #F5F5F5;
}

/*定義滾動條軌道 內陰影+圓角*/
::-webkit-scrollbar-track
{
  -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
  border-radius: 10px;
  background-color: #F5F5F5;
}

/*定義滑塊 內陰影+圓角*/
::-webkit-scrollbar-thumb
{
  border-radius: 10px;
  -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
  background-color: #ccc;
}複製程式碼

修改main.js  引入css

// 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 ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
import router from './router'
//引入自己的通用css
import '../static/css/common.css'

Vue.config.productionTip = false

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

建立page→Index.vue

<template>
  <div>
    <div style="text-align: center;margin-bottom: 20px">
      <h2>歡迎使用MyVue</h2>
    </div>

  </div>
</template>
<script>
  export default {
    data() {
      return {
      }
    },
    created: function () {

    },
    methods: {},
    components:{
    }
  }
</script>
<style>
</style> 複製程式碼

建立page→user→user.vue

<template>
  <div>
    <div style="border-radius: 5px;padding: 5px;">
      <el-table
        :data="userData"
        stripe
        style="width: 100%">
        <el-table-column
          align="center"
          prop="name"
          label="姓名">
        </el-table-column>
        <el-table-column
          align="center"
          prop="sex"
          :formatter	="sexFilterFun"
          label="性別">
        </el-table-column>
        <el-table-column
          align="center"
          prop="age"
          label="年齡">
        </el-table-column>
        <el-table-column
          align="center"
          prop="address"
          label="地址">
        </el-table-column>
        <el-table-column
          align="center"
          label="操作">
          <template slot-scope="scope">
            <el-button type="text" size="small">詳情</el-button>
            <el-button type="text" size="small">編輯</el-button>
            <el-button type="text" size="small" style="color: #f56c6c">禁用</el-button>
          </template>
        </el-table-column>
      </el-table>
    </div>

  </div>
</template>

<script>
  export default {
    data() {
      return {
        userData: [
          {name: "張三", sex: 0, age: 23, address: "遼寧大連中山"},
          {name: "李四", sex: 0, age: 23, address: "遼寧大連中山"},
          {name: "王五", sex: 0, age: 23, address: "遼寧大連中山"}
        ]
      }
    },
    created: function () {
    },
    methods: {
      sexFilterFun(row, column, cellValue, index){
       return cellValue == 0 ? '男':'女';
      }
    }
  }
</script>

<style scoped>
</style>複製程式碼

其中el-table標籤等為elementui表格的基礎用法。

修改src→router→index.js

import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/page/Home'
import Login from '@/page/Login'
import Index from '@/page/Index'
import User from '@/page/user/user'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      component: Login
    },
    {
      path: '/home',
      component: Home,
      //這裡注意
      children: [
        {path: "", component: Index},
        {path:"/user", component:User}
      ]
    }
  ]
}) 複製程式碼

注意：其中設定路由時，需配置children屬性，將路由設為Home頁得子路由。

二：修改Home.vue

<template>
  <div style="height: 100%;background: #283542;background-size: 100%">
    <div class="header-div disFlex">
      <el-tooltip class="item" effect="light" content="返回首頁" placement="right">
        <div class="header-div-left disFlex">
          <span class="user-name">MyVue</span>
        </div>
      </el-tooltip>
      <div class="disFlex header-div-right">
        <div style="padding: 0px 10px;">
          <img src="../images/userHeaderImg.png" style="width: 25px;"/>
        </div>
        <div>
          <span>{{userName}}</span>
        </div>
      </div>
    </div>
    <div class="disFlex" style="height: calc(100% - 90px);padding:0 15px;">
      <div class="menu-list-div">
        <div v-for="(menu,index) in menuList" :key="menu.id">
          <div @click="showMenu(index)" class="menu-list-bgc disFlex">
            <div style="width: 80%;">
              <span>{{menu.menuName}}</span>
            </div>
            <div style="width: 20%;text-align: right;">
              <i class="el-icon-arrow-right"
                 :class="[menu.isOpen == 1?'rotate':'rotate1']"
                 v-if="menu.adminMenuList.length > 0"></i>
            </div>
          </div>
          <el-collapse-transition>
            <div v-show="menu.isOpen==1">
              <!--router-link 類似於HTML中a標籤，用於頁面跳轉  其中to屬性為需要跳轉的路徑-->
              <router-link tag="li" :to="menuSon.query == undefined? menuSon.path : menuSon.path + menuSon.query"
                           v-for="(menuSon,index1) in menu.adminMenuList"
                           :key="menuSon.id">
                <div class="menuSon-list-bgc"
                     @click="showMenuSon(index,index1)"
                     :class="[menuSon.isOpen==1?'menuSon-list-color':'menuSon-list-color1']">
                  <span>{{menuSon.menuName}}</span>
                </div>
              </router-link>
            </div>

        </div>
      </div>
      <div style="width: 100%;margin-left: 20px;">
        <!--重點   類似於HTML中iframe 路由跳轉頁面在這裡展示-->
        <router-view class="routerView" :key="$route.fullPath"></router-view>
      </div>
    </div>
  </div>

<script>

        userName: '',
      }
    },
    created: function () {
      //模擬登陸成功獲取當前使用者許可權選單
      this.getMenuList();
      this.userName = "MyVue";
    },
    methods: {
      getMenuList(){
