微人事-首页完善

1）重复添加路由的问题

解决方案：重写路由的Push方法
添加图下代码

import Router from 'vue-router'


const routerPush = Router.prototype.push
Router.prototype.push = function push(location) {
  return routerPush.call(this, location).catch(error=> error)
}

2)添加面包屑
使用elementui的面包屑

<!--                 this.$router.currentRoute.name获取当前的route属性-->
<!--                当从别的页面返回home 显示home不太合适使用-->
                <el-main>
                    <el-breadcrumb separator-class="el-icon-arrow-right" v-if="this.$router.currentRoute.path != '/home'">
                        <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
                        <el-breadcrumb-item>{{this.$router.currentRoute.name}}</el-breadcrumb-item>
                    </el-breadcrumb>
                    <div class="homeWelcome" v-if="this.$router.currentRoute.path == '/home'">欢迎来到微人事</div>
                <router-view/></el-main>
