Vue3.0商店後臺管理系統項目實戰-vue3搭配Element Plus框架使用

側邊欄導航
vue3搭配Element Plus框架使用
Element Plus基於 Vue 3，面向設計師和開發者的組件庫
文檔：https://element-plus.gitee.io/zh-CN/

安裝

# NPM
$ npm install element-plus --save

安裝完成之後開始引入
打開main.js的文件
這裏接口文檔上是有說明的 ，直接根據文檔上的教程來寫

main.js

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'

import App from './App.vue'
import router from './router'
import store from './store'

createApp(App).use(store).use(router).use(ElementPlus).mount('#app')

開始使用組件裏面的佈局
後臺管理的佈局
直接複製代碼即可

 <div class="common-layout">
    <el-container>
      <el-header>Header</el-header>
      <el-container>
        <el-aside width="200px">Aside</el-aside>
        <el-main>Main</el-main>
      </el-container>
    </el-container>
  </div>

LayOut.vue

<template>
  <div>
    <div class="common-layout">
      <el-container>
        <el-header>Header</el-header>
        <el-container>
          <el-aside width="200px">
            <router-link to="/index">角色列表</router-link>
            <router-link to="/user">用戶列表</router-link></el-aside
          >
          <el-main><router-view></router-view></el-main>
        </el-container>
      </el-container>
    </div>
  </div>
</template>

<script>
export default {
  name: "layout",
  setup() {},
};
</script>

優化css

LayOut.vue

<template>
  <div>
    <div class="common-layout">
      <el-container>
        <el-header  class="common-header   flex-float">
            <div  class="flex">
            <img  class="logo" src="../../assets/logo.png"  alt="">
            <h1  class="title">商鋪後臺管理系統</h1>
            </div>

            <el-button type="danger">退出</el-button>

        </el-header>
        <el-container>
          <el-aside  class="common-aside " width="200px">
            <router-link to="/index">角色列表</router-link>
            <router-link to="/user">用戶列表</router-link></el-aside
          >
          <el-main><router-view></router-view></el-main>
        </el-container>
      </el-container>
    </div>
  </div>
</template>

<script>
export default {
  name: "layout",
  setup() {},
};
</script>
<style >
.el-container {
  height: 100vh;
  overflow: hidden;
}
.common-header {
    background: rgb(63 67 72);
}

.common-aside {
  background: rgb(48, 55, 65);
}
.logo{
    width:60px;
}
.title{
color: #fff;
}
</style>

app.vue裏面寫一個全局的flex佈局

<template>
  <router-view />
</template>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}

nav {
  padding: 30px;
}

nav a {
  font-weight: bold;
  color: #2c3e50;
}

nav a.router-link-exact-active {
  color: #42b983;
}

/* flex佈局 */
.flex-float {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.flex {
  display: flex;
  align-items: center;
}
</style>

到這裏 後臺管理系統 的框架初具模型 繼續編寫代碼

繼續編寫左側的導航菜單
文檔裏面都是有代碼可以直接拿過來使用的

根據menu菜單 的屬性 進行一些代碼的優化

設置router
是否啓用 vue-router 模式。 啓用該模式會在激活導航時以 index 作爲 path 進行路由跳轉 使用 default-active 來設置加載時的激活項。

完善之後的導航欄

<template>
  <div>
    <div class="common-layout">
      <el-container>
        <el-header class="common-header flex-float">

            <img class="logo" src="../../assets/logo.png" alt="" />
            <h1 class="title">商鋪後臺管理系統</h1>
          </div>

          <el-button type="danger">退出</el-button>
        </el-header>
        <el-container>
          <el-aside class="common-aside" width="200px">
