Element UI 是一套采用 Vue 2.0 作为基础框架实现的组件库，它面向企业级的后台应用，能够帮助你快速地搭建网站，极大地减少研发的人力与时间成本。今天我就把实际运用中的布局跟大家说一下，希望对大家有用。今天我主要讲的是登录后的布局界面，原来我们都是用frameset布局，现在我们要用Element看看如何实现。
界面截图
这种布局用frameset可以这么写：
<frameset rows="100,*" cols="*" scrolling="No" framespacing="0" frameborder="no" border="0"> <frame src="inc/head.html" name="headmenu" id="mainFrame" title="mainFrame"><!-- 引用头部 --> <!-- 引用左边和主体部分 --> <frameset rows="100*" cols="220,*" scrolling="No" framespacing="0" frameborder="no" border="0"> <frame src="inc/left.html" name="leftmenu" id="mainFrame" title="mainFrame"> <frame src="main.html" name="main" scrolling="yes" noresize="noresize" id="rightFrame" title="rightFrame"> </frameset></frameset>
那么我们如何用Element来写呢，具体步骤如下。
一、创建项目
这个就不用说了，我把我自己的项目结构贴出来。
项目结构
二、创建页眉、左侧、右侧文件
首先，我们创建头部、左边、右边文件，我们他们都创建在src-->components文件夹下，具体如下：
<!--头部（Header.vue）--><template>
<div>
<div class="topbar-logo topbar-btn">
<a href="/"></a>
</div>
<div class="topbar-title topbar-btn">
<span>后台管理系统</span>
</div>
<div class="topbar-account topbar-btn">
<el-dropdown trigger="click">
<span class="el-dropdown-link userinfo-inner"><i class="iconfont icon-user"></i> {{sysUserName}} <i class="iconfont icon-down"></i></span>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item @click.native="userinfo">个人信息</el-dropdown-item>
<el-dropdown-item @click.native="editpwd">修改密码</el-dropdown-item>
<el-dropdown-item divided @click.native="logout">退出登录</el-dropdown-item>
</el-dropdown-menu>
</el-dropdown>
</div>
</div></template><script type="text/ecmascript-6">
export default {
data() { return { sysUserName: '', sysUserAvatar: '', collapsed: false,
}
},
mounted() { var userSession = this.getCookie('session'); if(userSession) { this.sysUserName = userSession || '';
}
}, methods: { //退出
logout() { this.$confirm('确认要退出吗？','提示',{}).then(() => { this.$fetch('m/logout').then((res) =>{ if(res.errCode == 200) { this.delCookie('session'); this.delCookie('u_uuid'); this.$router.push({path: '/', query: {redirect: this.$router.currentRoute.fullPath}});
} else { console.log(res.errMsg);
}
});
}).catch(() => {
});
}, //个人信息
userinfo() { this.$router.push('/userinfo');
}, //修改密码
editpwd() { this.$router.push('/editpwd');
}
}
}</script>标签具体是什么意思，我就不解释了，大家可以看看Element官网（http://element.eleme.io/#/）<!--左边（UserLeft.vue）--><template>
<div>
<aside :class="collapsed?'menu-collapsed' : 'menu-expanded'">
<!--展开折叠开关-->
<div class="menu-toggle" @click.prevent="collapse">
<i class="iconfont icon-menufold" v-show="!collapsed"></i>
<i class="iconfont icon-menuunfold" v-show="collapsed"></i>
</div>
<!--菜单展开时的显示情况-->
<el-menu v-show="!collapsed" default-active="0" @open="handleOpen" @close="handleClose" router>
<template v-for="(item,index) in $router.options.routes" v-if="item.menuShow">
<el-submenu v-if="!item.leaf" :index="index+''">
<template slot="title"><i :class="item.iconCls"></i>{{item.name}}</template>
<el-menu-item v-for="term in item.children" :key="term.path" :index="term.path" v-if="term.menuShow">
{{term.name}} </el-menu-item>
</el-submenu>
<el-menu-item v-else-if="item.leaf&&item.children&&item.children.length" :index="item.children[0].path" class="el-submenu__title">
<i :class="item.iconCls"></i>{{item.children[0].name}} </el-menu-item>
</template>
</el-menu>
<!--菜单折叠后的显示情况
这里需要说明一下： $router.options.routes，其实就是从路由获取菜单数据，具体往下面看。这是重点，要不然你都不知道数据从哪里过来的。其实这里的数据可以做到数据库中，然后直接从数据库中获取。
-->
<ul v-show="collapsed" class="el-menu collapsed" ref="menuCollapsed" >
<template v-for="(item,index) in $router.options.routes" v-if="item.menuShow">
<li v-if="!item.leaf" :index="index+''" style="position: relative;">
<div class="el-submenu__title" style="padding-left: 20px;" @mouseover="showMenu(index,true)" @mouseout="showMenu(index,false)"><i :class="item.iconCls"></i></div>
<ul class="el-menu submenu" :class="'submenu-hook-'+index" @mouseover="showMenu(index,true)" @mouseout="showMenu(index,false)">
<li v-for="term in item.children" :key="term.path" v-if="term.menuShow" class="el-menu-item" style="padding-left: 40px;" :class="$route.path==term.path?'is-active':''"
@click="$router.push(term.path)">{{term.name}}</li>
</ul>
</li>
<li v-else-if="item.leaf&&item.children&&item.children.length" class="el-menu-item el-submenu__title" :class="$route.path==item.children[0].path?'is-active':''" @click="$router.push(item.children[0].path)">
<i :class="item.iconCls"></i>
</li>
</template>
</ul>
</aside>
</div></template><script>
export default {
data() { return { sysUserName: '', sysUserAvatar: '', collapsed: false
}
},
mounted() { //初始化
}, methods: {
handleOpen() {
},
handleClose() {
}, //折叠导航栏
collapse: function () { this.collapsed = !this.collapsed;
},
showMenu(i, status){ this.$refs.menuCollapsed.getElementsByClassName('submenu-hook-' + i)[0].style.display = status ? 'block' : 'none';
}
}
}</script><!-- 右边（UserRight.vue）这是初始化的页面，大家可以根据自己的需求来写 --><template>
<div>
<el-row class="warp">
<el-col :span="24" class="warp-breadcrum">
<el-breadcrumb separator="/">
<el-breadcrumb-item :to="{path:'/'}"><b>首页</b></el-breadcrumb-item>

</el-row>
</section>
</el-col>
</el-row>
</div></template><script>
export default {
data() { return { currentDate: new Date(),
}
}
}</script>三、创建路由文件
<!--打开路由文件复制如下代码 -->import Vue from 'vue'import Router from 'vue-router'import Index from '@/views/index/Index' //首页import Home from '@/views/index/Home' //主页import right from '@/components/UserRight' //右侧import userlist from '@/views/user/UserList' //用户列表import usercert from '@/views/user/Certification' //用户审核import userlook from '@/views/user/UserLook' //用户查看import usercertlook from '@/views/user/UserCertLook' //用户审核查看import sellbill from '@/views/ticket/SellBill' //卖票信息import buybill from '@/views/ticket/BuyBill' //买票信息import changebill from '@/views/ticket/ChangeBill' //换票信息import billlist from '@/views/bill/list' //票据列表import billinfo from '@/views/bill/info' //票据详细import addbill from '@/views/bill/add' //添加票据import editsellbill from '@/views/ticket/EditSellBill' //修改卖票信息import editbuybill from '@/views/ticket/EditBuyBill' //修改买票信息import editchangebill from '@/views/ticket/EditChangeBill' //修改换票信息import lookbill from '@/views/ticket/LookBill' //查看详细import lookbuybill from '@/views/ticket/LookBuyBill' //查看买票详细import ticketstatus from '@/views/ticket/TicketStatus' //票据状态import addticket from '@/views/ticket/AddTicket' //新建开票信息import userinfo from '@/views/user/UserInfo' //个人信息import editpwd from '@/views/user/EditPwd' //修改密码import webbasic from '@/views/user/WebBasic' //网站基本配置/* 图片管理 */import imglist from '@/views/image/ImgList' //图片列表import addimg from '@/views/image/AddImg' //图片添加import editimg from '@/views/image/EditImg' //图片编辑/* 新闻信息 */import newtype from '@/views/newstype/TypeList' //新闻分类import addnewstype from '@/views/newstype/AddType' //添加新闻分类import editnewstype from '@/views/newstype/EditType' //编辑新闻分类import newlist from '@/views/news/NewsList' //新闻列表import addnews from '@/views/news/AddNews' //添加新闻import editnews from '@/views/news/EditNews' //编辑新闻import looknews from '@/views/news/LookNews' //查看新闻/* 帮助中心 */import addhelp from '@/views/help/AddHelp' //添加帮助import helplist from '@/views/help/HelpList' //帮助列表import edithelp from '@/views/help/EditHelp' //帮助修改import lookhelp from '@/views/help/LookHelp' //帮助查看import industry from '@/views/help/Industry' //行业解决方案import security from '@/views/help/Security' //安全保障/* 友情链接*/import linklist from '@/views/link/LinkList' //友情链接列表import addlink from '@/views/link/AddLink' //添加友情链接import editlink from '@/views/link/EidtLink' //编辑友情链接/* 关于我们 */import addabout from '@/views/aboutus/AddAbout' //添加关于我们import aboutlist from '@/views/aboutus/AboutList' //添加关于我们import lookabout from '@/views/aboutus/LookAbout' //查看关于我们import editabout from '@/views/aboutus/EditAbout' //编辑关于我们Vue.use(Router);

以下就是导航菜单，也就是前面我们看到。下面我解释以下相关参数：
path:路径，默认为："/",

compnent:组件，
redirect：跳转页面
menuShow：true or false;控制左侧菜单显示还是隐藏
iconCls：图标样式
children：子模块，这里表示主菜单下面挂载多个子菜单
meta:{requireAuth: true }，主要做登录判断，具体的实现方式在下面的页面路由验证
