前言
上一篇（vue框架+ElementUI搭建UI框架-2）文章讲述了如何使用ElementUI及搭建登录页面，接下来就开始引用elementUI其他组件进行页面布局，直接开始进入主题。
一、完善登录页面
注：完善了页面的简易功能，可以实现验证和跳转。
登录按钮添加了一个小状态（点击后显示加载状态，登录成功后回复初始状态），实现了登录的功能；样式中的背景图我注释了，大家可以自行替换。页面上引用了滑动验证的组件需要注意，验证组件也放在下面了，可自行参考。
login.vue页面代码如下：
<template>
<div class="flex-container">
<div class="header">
<span id="title">××××系统</span>
<span>企业内部管理平台</span>
</div>
<div class="main">
<el-form :model="form" :rules="rules" ref="form">
<el-form-item prop="username">
<el-input placeholder="请输入账号" prefix-icon="el-icon-user" v-model="form.username" style="width: 300px;">
</el-input>
</el-form-item>
<el-form-item prop="password">
<el-input placeholder="请输入密码" prefix-icon="el-icon-lock" v-model="form.password" style="width: 300px;"
show-password></el-input>
</el-form-item>
<el-form-item>
<sliderverify ref="slider"></sliderverify>
</el-form-item>
<el-form-item>
<el-checkbox v-model="form.checked">记住密码</el-checkbox>
</el-form-item>
<el-form-item>
<el-button type="primary" style="width: 100%;" :loading="loginbtn" @click="submitForm('form')">登录</el-button>
</el-form-item>
</el-form>
</div>
<div class="footer">
<p>
<span><a href="javascript:void(0);">帮助</a></span>
<span><a href="javascript:void(0);">关于</a></span>
<span><a href="javascript:void(0);">更多</a></span>

二、搭建主页面
1、创建一个home.vue的页面，这个页面主要用于搭建公共部分页面，包括左侧菜单、右侧页面显示区域（包括操作部分、标签部分、页面部分）。
2、home.vue中需要引用多个组件来实现相应功能。
思路：我是根据ElementUI官网的布局容器 Container来实现的，大家也可以根据自己的需要进行修改。我主要用到了一下这几个标签：
el-container：外层容器
el-aside：侧边栏容器
el-header：顶栏容器
el-main：主要区域容器
home.vue页面代码如下：
<template>
<el-container>
<el-aside width="auto">
<Leftnav></Leftnav>
</el-aside>
<el-container>
<el-header>
<Headnav></Headnav>
</el-header>
<el-main>
<Tags></Tags>
<div class="pages">
<router-view></router-view>
</div>
</el-main>
</el-container>
</el-container>
</template>
<script>
import Headnav from "@/components/headers"; //头部组件
import Leftnav from "@/components/leftmenu"; //左侧菜单组件
import Tags from "@/components/tags"; //左侧菜单组件
export default {
name: "home",
data() {
return {
}
},
created() {
},
watch: {
},
methods: {
},
components: {
Leftnav,
Headnav,
Tags
},
created() {
},
mounted() {
},
};
</script>
<style scoped>
.el-header,
.el-main {
padding: 0px;
}
.el-header {
background-color: #f5f5f5;
}
.el-aside {
height: 100vh;
}
.el-main {
height: 100vh;
background-color: #E9EEF3;
}
.pages {
height: calc(100% - 130px);
margin: 5px;
padding: 10px;
background: #fff;
}
</style>
三、左侧菜单（实现功能及思路）
实现效果：顶部显示文字或Logo，下面根据数据循环出菜单信息，然后点击菜单跳转到对应的页面；添加一个小按钮，实现菜单的收缩功能。
实现思路：根据官方提供的菜单组件进行调整，页面使用数组进行数据的循环，菜单配置比较麻烦的一个地方就是路由和状态的配置。在菜单这部分需要用到Vuex的功能，到时候具体说明一下。
四、右侧头部用户信息及其标签行（实现功能及思路）
实现效果：头部显示用户的头像及退出功能。标签行主要是记录用户点击的页面路径。
实现思路：因为涉及到标签的添加、删除，页面的跳转，这一部分也需要使用到Vuex的功能。
五、右侧页面展示区域
点击菜单后该区域显示页面信息。
六、结束语
前段时间比较忙，今天上来查东西发现阅读量挺多的，感觉还是有必要接着把剩下的功能补充完整。其实功能后来做的差不多了，只是没时间去写，因为在做的过程中也遇到一些问题，边学边做可能时间上也不允许。总之接下来我会尽量更新，由于后面封装的东西比较多，所以分1~2篇去完成。
