VUE +element-ui实现点击侧边栏右侧内容部分改变及侧边栏缩放功能

<el-container style="height: 100vh; border: 1px solid #eee">
		<el-aside
		:style="transformClass"
		style="background-color: rgb(238, 241, 246)" 
		>
			<el-menu 
			:default-openeds="['1', '3']"
			:default-active="this.$route.path"
			router
			style="background-color: rgb(238, 241, 246);overflow-x:hidden" 
			>
			<h3 class="menuTitle" v-if="this.opened">E通关后台管理系统</h3>
			<el-menu-item  @click="gotoHome" title="首页" v-else>
				<i class="el-icon-loading"></i>
			</el-menu-item>
			<el-menu-item index="/Home/ExportBusiness" title="出口业务">
				<i class="el-icon-coin"></i>
				<span slot="title" :class="{ 'active': !this.opened }">出口业务</span>
			</el-menu-item>
			
			<el-menu-item index="/Home/ImportBusiness" title="进口业务">
				<i class="el-icon-truck"></i>
				<span slot="title" :class="{ 'active': !this.opened }" >进口业务</span>
			</el-menu-item>
				
			</el-menu>
		</el-aside>
	  <el-container >
	  
	    <el-header class="navbar">
			<hamburger :is-active="opened" class="hamburger-container" @toggleClick="toggleSideBar" style="width: 20px;"/>
			<div style="position: absolute;top: 0;right: 50px;">
				<el-dropdown @command="handleCommand" >
					<i class="el-icon-setting" style="margin-right: 15px"></i>
					<el-dropdown-menu slot="dropdown">
						<el-dropdown-item command="a">退出登录</el-dropdown-item>
						<el-dropdown-item>新增</el-dropdown-item>
						<el-dropdown-item>删除</el-dropdown-item>
					</el-dropdown-menu>
				</el-dropdown>
				<span>{{userData.userName||'未登录'}}</span>
			</div>
			
	    </el-header>
	    
	    <el-main>
			<router-view/>
	    </el-main>
	  </el-container>
	</el-container>
</template>

重要属性如下:
el-menu中的
default-active=“this.$route.path”
router
添加路由功能

el-menu-item中的
index="/Home/ExportBusiness"
index="/Home/ImportBusiness"
确定路由路径

el-main中指向路由

本项目中router路由配置如下

export default new Router({
	mode:"history",
	routes: [
		{
			path: '/',
			name: 'Login',
			component: Login
		},
		{
			path: '/Reg',
			name: 'Reg',
			component: Reg
		},
		{
			path: '/retrievePassword',
			name: 'retrievePassword',
			component: retrievePassword
		},
		{
			path: '/Home',
			name: 'Home',
			component: Home,
			children:[
				{
					name : "ExportBusiness",
					path : "ExportBusiness",
					component : ExportBusiness,
				},
				{
					name : "ImportBusiness",
					path : "ImportBusiness",
					component : ImportBusiness,
				}
			]
		},
	]
})

再说一下侧边栏缩放隐藏功能

import Hamburger from '@/components/Hamburger'

<hamburger :is-active="opened" class="hamburger-container" @toggleClick="toggleSideBar" style="width: 20px;"/>

Hamburger文件如下：

<template>
  <div style="padding: 0 15px;" @click="toggleClick">
    <svg
      :class="{'is-active':isActive}"
      class="hamburger"
      viewBox="0 0 1024 1024"
      xmlns="http://www.w3.org/2000/svg"
      width="64"
      height="64"
    >
      <path d="M408 442h480c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8H408c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8zm-8 204c0 4.4 3.6 8 8 8h480c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8H408c-4.4 0-8 3.6-8 8v56zm504-486H120c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8h784c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8zm0 632H120c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8h784c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8zM142.4 642.1L298.7 519a8.84 8.84 0 0 0 0-13.9L142.4 381.9c-5.8-4.6-14.4-.5-14.4 6.9v246.3a8.9 8.9 0 0 0 14.4 7z" />
    </svg>
  </div>
</template>

<script>
export default {
  name: 'Hamburger',
  props: {
    isActive: {
      type: Boolean,
      default: false
    }
  },
  methods: {
    toggleClick() {
      this.$emit('toggleClick')
    }
  }
}
</script>

<style scoped>
.hamburger {
  display: inline-block;
  vertical-align: middle;
  width: 20px;
  height: 20px;
}

.hamburger.is-active {
  transform: rotate(180deg);
}
</style>

methods中切换opened true和false状态

methods:{
			...mapActions(['getExportBussiness']),
			handleCommand(command) {
				this.$router.push(`/`);
		    },
			toggleSideBar() {
				this.opened = !this.opened
			},
			gotoHome(){
				this.$router.push('/Home/ExportBusiness')//返回首页，
			}
		},

相关CSS如下

<style>
	html,
	body {
		width: 100%;
		height: 100vh;
		margin: 0; 
	  	padding: 0;
	}
	.el-header {
	    background-color: #B3C0D1;
	    color: #333;
	    line-height: 60px;
	  }
	.el-aside {
	    color: #333;
	}
	.menuTitle{
		color: fffff;
		text-align: center;
	}
	.active{
		padding-left: 15px;
	}
	.el-menu-item span{
		font-size: 16px;
		font-weight: bold;
	}
/* 	.navbar {
	  height: 150px;
	  overflow: hidden;
	  position: relative;
	  background: #fff;
	  box-shadow: 0 1px 4px rgba(0,21,41,.08);
	
	  .hamburger-container {
	    line-height: 46px;
	    height: 100%;
	    float: left;
	    cursor: pointer;
	    transition: background .3s;
	    -webkit-tap-highlight-color:transparent;
	
	    &:hover {
	      background: rgba(0, 0, 0, .025)
	    }
	  }
	} */
</style>
