【信贷后台管理系统之首页】-一、布局设置

创建一个layout文件夹，layout.vue。容器里存放页面的整个布局规划，使用到element-ui的container布局容器。为实现组件化管理，将aside,header部分单独放在components组件，然后在layout.vue布局里直接引用。aside是导航栏，header里右边有个admin可实现下拉菜单进行退出登录。
layout.vue代码如下：

<template>
   <div>
     <el-container>
       <el-aside width="200px">
         <common-aside />
       </el-aside>
       <el-container>
         <el-header>
           <common-header />
         </el-header>
         <el-main>
           <router-view />
         </el-main>
       </el-container>
     </el-container>
   </div>
</template>
<script>
import CommonAside from '@/components/Layout/CommonAside.vue'
import CommonHeader from '@/components/Layout/CommonHeader.vue'


export default {
  data(){
    return{}
  },
  components:{
    CommonAside,
    CommonHeader,

  }

}
</script>
<style >
a:link{
  text-decoration: none;
  color: #ffffff;
}

//状态二：已经访问过的链接
a:visited{
  text-decoration: none;
  color: #ffffff;
}

// 状态三：鼠标滑过的链接（默认红色)
a:hover{
  text-decoration: none;
  color:#ffffff;
}
// 状态四：被点击的链接
a:active{
  text-display: none;
  color: #ffffff;
}
.el-header{
  display: flex;
  align-items:center;
  padding: 0 620px;
  color: #ffffff;
  justify-content: space-between;
}
.el-footer{
  background-color: #b3c0d1;
  color: #333;
  text-align: center;
  line-height: 60px;
}
.el-aside{
  background-color: #545c64;
  color: #333333;
  text-align: center;
  line-height: 200px;
}
.el-main{
  background-color: #e9eef3;
  color: #333333;
  text-align: center;
}
.el-container{
  height: 100vh;
}
.el-menu-vertical-demo{
  border:none;
}
</style>

左边导航栏的CommonAside.vue代码如下

<template>
  <div>
    <el-aside width="240px">
      <el-menu
        class="el-menu-vertical-demo"
        background-color="#545c64"
        text-color="#fff"
        active-text-color="#ffd04b">
<!--      没有二级导航-->
      <el-menu-item index="1">
        <i class="el-icon-menu"></i>
        <span slot="title">首页</span>
      </el-menu-item>
<!--      有二级导航-->
      <el-submenu index="2">

        <template slot="title">
          <span>贷款管理</span>
        </template>
        <el-menu-item index="2-1">贷款申请</el-menu-item>
      </el-submenu>
      </el-menu>
    </el-aside>
  </div>
</template>

<script>

</script>

<style>
a:link{
  text-decoration: none;
  color: #ffffff;
}

//状态二：已经访问过的链接
a:visited{
  text-decoration: none;
  color: #ffffff;
}

// 状态三：鼠标滑过的链接（默认红色)
a:hover{
  text-decoration: none;
  color:#ffffff;
}
// 状态四：被点击的链接
a:active{
  text-display: none;
  color: #ffffff;
}
.el-header{
  padding: 0 620px;
  display: flex;
  align-items: center;
  color: #ffffff;
  justify-content: space-between;
}
.el-footer{
  background-color: #b3c0d1;
  color: #333;
  text-align: center;
  line-height: 60px;
}
.el-aside{
  background-color: #545c64;
  color: #333333;
  text-align: center;
  line-height: 200px;
}
.el-main{
  background-color: #e9eef3;
  color: #333333;
  text-align: center;
}
.el-container{
  height: 100vh;
}
.el-menu-vertical-demo{
  border:none;
}
</style>

CommonHeader.vue代码如下

<template>
  <el-header>
<!--    左侧面包屑-->
    <div class="left">首页</div>
<!--    右侧用户名-->
    <div class="right">
<!--      下拉菜单-->
      <el-dropdown>
        <span class="el-dropdown-link"> admin </span>
        <el-dropdown-menu slot="dropdown">
          <el-dropdown-item>退出登录</el-dropdown-item>
        </el-dropdown-menu>
      </el-dropdown>
    </div>
  </el-header>
</template>
<script>

</script>
<style>
a:link{
  text-decoration: none;
  color: #ffffff;
}

//状态二：已经访问过的链接
a:visited{
  text-decoration: none;
  color: #ffffff;
}

// 状态三：鼠标滑过的链接（默认红色)
a:hover{
  text-decoration: none;
  color:#ffffff;
}
// 状态四：被点击的链接
a:active{
  text-display: none;
  color: #ffffff;
}
.el-header{
  padding: 0 620px;
  display: flex;
  align-items: center;
  color: #ffffff;
  justify-content: space-between;
}
.el-footer{
  background-color: #b3c0d1;
  color: #333;
  text-align: center;
  line-height: 60px;
}
.el-aside{
  background-color: #545c64;
  color: #333333;
  text-align: center;
  line-height: 200px;
}
.el-main{
  background-color: #e9eef3;
  color: #333333;
  text-align: center;
}
.el-container{
  height: 100vh;
}
.el-menu-vertical-demo{
  border:none;
}

</style>

要想实现以上一行四列内容数据动态增加，要下载vue-count-to，并引入使用
https://www.npmjs.com/package/vue-count-to

折线图，柱状图，饼图需要安装echarts并导入使用（之前已导入使用）

使用栅格布局，设置一行四列。设计echarts图表，折线图独占一个容器，折线图和饼图一个容器views文件夹下HomeView.vue代码如下：

<template>
  <div class="home">
<!--    栅格布局-->
    <el-row :gutter="10">
      <el-col
          :xl="6"
          :lg="6"
          :md="12"
          :sm="24"
          :xs="24"
          v-for="(item,index) in list" :key="index">
        <div class="dashboard-item" :style="{background:item.color}">
          <p>{{item.title}}</p>
          <countTo :startVal='0' :endVal='item.val' :duration='3000'></countTo>
        </div>
      </el-col>
<!--      <el-col :xl="6" :lg="6" :md="12" :sm="24" :xs="24"><div >1</div></el-col>-->
<!--      <el-col :xl="6" :lg="6" :md="12" :sm="24" :xs="24"><div >2</div></el-col>-->
<!--      <el-col :xl="6" :lg="6" :md="12" :sm="24" :xs="24"><div >3</div></el-col>-->
<!--      <el-col :xl="6" :lg="6" :md="12" :sm="24" :xs="24"><div >4</div></el-col>-->
    </el-row>
<!--    echarts图表-->
    <div class="chart1"></div>
    <div class="echarts-box">
      <div class="chart2"></div>
      <div class="chart3"></div>
