安装

安装完成之后开始引入
打开main.js的文件
这里接口文档上是有说明的 ，直接根据文档上的教程来写

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')
开始使用组件里面的布局
后台管理的布局
直接复制代码即可
<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">用户列表</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>
优化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">商铺后台管理系统</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">用户列表</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里面写一个全局的flex布局
<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布局 */
.flex-float {
display: flex;
justify-content: space-between;
align-items: center;
}
.flex {
display: flex;
align-items: center;
}
</style>
到这里 后台管理系统 的框架初具模型 继续编写代码
继续编写左侧的导航菜单
文档里面都是有代码可以直接拿过来使用的
根据menu菜单 的属性 进行一些代码的优化
设置router
是否启用 vue-router 模式。 启用该模式会在激活导航时以 index 作为 path 进行路由跳转 使用 default-active 来设置加载时的激活项。
完善之后的导航栏
