·
效果图:
第一步,封装上方水平一级菜单
<template>
<div class="wrapper">
<!-- 页面头部部分 -->
<div class="header">
<div class="logo">后台管理系统</div>
<!-- 水平一级菜单 -->
<div style="float: left">
<el-menu :default-active="toIndex()" mode="horizontal" @select="handleSelect">
<template v-for="item in items">
<el-menu-item :index="item.index" :key="item.index">
<template slot="title">
<span slot="title">{{ item.title }}</span>
</template>
</el-menu-item>
</template>
</el-menu>
</div>
<div class="header-right">
<div class="header-user-con">
<!-- 客服聊天 -->
<div style="cursor: pointer; font-size: 16px" @click="contact">联系客服</div>
<!-- 用户头像 -->
<div class="user-avator"><img src="../../assets/img/img.jpg" /></div>
<!-- 用户名下拉菜单 -->
<el-dropdown class="user-name" trigger="click" @command="handleCommand">
<span class="el-dropdown-link">
{{ username }}
<i class="el-icon-caret-bottom"></i>
</span>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item disabled>修改密码</el-dropdown-item>
<el-dropdown-item command="loginout">退出登录</el-dropdown-item>
</el-dropdown-menu>
</el-dropdown>
</div>
</div>
</div>
<!-- 页面左侧二级菜单栏,和主体内容区域部分 -->
<el-main>
<router-view></router-view>
</el-main>
</div>
</template>
<script>
export default {
data() {
return {
items: [
// 水平一级菜单栏的菜单
{ index: 'Home', title: '首页' },
{ index: 'hunter', title: '测试1' },
{ index: 'job', title: '测试2' },
{ index: 'system', title: '系统设置' }
]
};
},
computed: {
username() {
let username = localStorage.getItem('ms_username');
return username ? username : this.name;
}
},
methods: {
// 根据路径绑定到对应的一级菜单,防止页面刷新重新跳回第一个
toIndex() {
return this.$route.path.split('/')[1];
},
// 切换菜单栏
handleSelect(index) {
this.$router.push('/' + index);
},
// 用户名下拉菜单选择事件
handleCommand(command) {
if (command == 'loginout') {
localStorage.removeItem('ms_username');
this.$router.push('/login');
}
},
// 联系客服
contact() {
this.$router.push('/contact');
}
},
mounted() {}
};
</script>
<style scoped>
.wrapper {
width: 100%;
height: 100%;
background: #f0f0f0;
}
.header {
/* position: relative; */
position: fixed;
z-index: 999;
box-sizing: border-box;
width: 100%;
height: 70px;
font-size: 22px;
}
.header .logo {
float: left;
margin-left: 60px;
margin-top: 17.5px;
height: 29px;
width: 160px;
vertical-align: middle;
}
/* --------------- 用户头像区域的样式 ---------------- */
.header-right {
float: right;
padding-right: 50px;
}
.header-user-con {
display: flex;
height: 70px;
align-items: center;
}
.user-avator {
margin-left: 20px;
}
.user-avator img {
display: block;
width: 40px;
height: 40px;
border-radius: 50%;
}
.user-name {
margin-left: 10px;
}
.el-dropdown-link {
cursor: pointer;
}
.el-dropdown-menu__item {
text-align: center;
}
/* --------------- 水平一级菜单栏的样式--------------------- */
.el-menu.el-menu--horizontal {
border-bottom: none !important;
float: left;
margin-left: 50px;
}
.el-menu--horizontal > .el-menu-item.is-active {

}
.el-menu--horizontal > .el-menu-item {
font-size: 16px;
margin: 0 15px;
color: black;
}
</style>
第二步,封装左侧二级,三级菜单导航
<template>
<!-- 二级、三级菜单封装 -->
<div class="sidebar">
<el-menu
class="sidebar-el-menu"
:default-active="toIndex()"
s
background-color="white"
text-color="#7a8297"
active-text-color="#2d8cf0"
router
>
<div>
<el-submenu :index="index + ''" v-for="(list, index) in lists" :key="list.id">
<template slot="title">
<i class="el-icon-location"></i>
<span>{{ list.title }}</span>
</template>
<template v-for="item in list.children">
<el-menu-item :index="item.index" :key="item.id" v-if="item">
<span slot="title">{{ item.title }}</span>
</el-menu-item>
</template>
</el-submenu>
</div>
</el-menu>
</div>
</template>
<script>
export default {
props: ['lists'],
data() {
return {};
},
methods: {
// 根据路径绑定到对应的二级菜单,防止页面刷新重新跳回第一个
toIndex() {
return this.$route.path.split('/')[2];
},
changepath(path) {}
},
mounted() {}
};
</script>
<style scoped>
/* 左侧菜单栏定位和位置大小设定 */
.sidebar {
display: block;
/* position: absolute; */
position: fixed;
left: 0;
top: 70px;
bottom: 0;
overflow-y: scroll;
}
.sidebar::-webkit-scrollbar {
width: 0;
}
.sidebar-el-menu {
width: 250px;
}
.sidebar > ul {
height: 100%;
}
/* 左侧二级菜单项的样式 */
.el-menu-item {
font-size: 14px !important;
padding-left: 35px !important;
color: black !important;
}
/* 左侧二级菜单选中时的样式 */
.el-menu-item.is-active {
color: white !important;
background: #3989fa !important;
}
.el-menu-item,
.el-submenu__title {
height: 50px !important;
line-height: 50px !important;
}
</style>
第三步,配置路由
import Vue from 'vue';
import Router from 'vue-router';
Vue.use(Router);
export default new Router({
routes: [{
path: '/',
component: () => import('../components/common/Whole.vue'),
meta: {
title: '整体页面布局'
},
children: [{
path: '/dashboard',
component: () => import('../page/Dashboard.vue'),
meta: {
title: '首页'
},
redirect: '/Home', // 该配置是若点击选择父目录时,默认选中该父目录下的子路径页面
children: [{
path: '/Home',
component: () => import('../page/Dashboard.vue'),
meta: {
title: '首页'
},
}]
},{
// 国际化组件
path: '/i18n',
component: () => import('../components/common/I18n.vue'),
meta: {
title: '国际化'
}
},
{
// 系统设置
path: '/system',
component: () => import('../page/system/index.vue'),
meta: {
title: '系统设置'
},
redirect: '/system/menuManage',
children: [
{
path: 'menuManage',
component: () => import('../page/system/menuManage.vue'),
meta: {
title: '菜单管理'
}
},
{
path: 'contentManage',
component: () => import('../page/system/contentManage.vue'),
meta: {
title: '内容管理'
}
},
{
path: 'roleManage',
component: () => import('../page/system/roleManage.vue'),
meta: {
title: '角色管理'
}
},
{
path: 'systemManage',
component: () => import('../page/system/systemManage.vue'),
meta: {
title: '系统设置'
}
},
]
},
{
path: '/404',
component: () => import('../page/404.vue'),
meta: {
title: '404'
}
},
{
path: '/403',
component: () => import('../page/403.vue'),
meta: {
title: '403'
}
},
]
},
{
// 登录页面
path: '/login',
component: () => import('../page/Login.vue'),
meta: {
title: '登录'
}
},
{
path: '*',
redirect: '/404'
}
]
});
第四步,在页面中应用
<template>
<div class="system">
<!-- 一级菜单下面所拥有的二级菜单 -->
<el-aside>
<SideMenu :lists="lists"></SideMenu>
</el-aside>
<!-- 以及二级菜单所对应的页面 -->
<el-main>
<router-view></router-view>
</el-main>
</div>
</template>
<script>
import SideMenu from '@/components/sidemenu/SideMenu';
export default {
components: {
SideMenu
},
data() {
return {
lists: [
{
title: '菜单管理',
children: [
{ index: 'menuManage', title: '菜单管理' },
{ index: 'contentManage', title: '内容管理' },
{ index: 'roleManage', title: '角色管理' }
]
},
{
title: '系统管理',
children: [
{
index: 'systemManage',
title: '系统设置'
}
]
}
]
};
}
};
</script>
<style scoped>
</style>
