怎样实现vue路由嵌套高亮

//主路由通过v-for循环出来
<p class="list-group">
 <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" v-on:click="doNothing" class="list-group-item" v-if="getPages.length != 0">数据统计</a>
 <router-link v-for="page in getPages" class="list-group-item" :to="page.pageUrl">{{page.pageName}}</router-link>
</p>
//次路由通过URL拼接的方式导航到子路由页面
<p class="panel-body tabs-wrap">
 <!--navtabbar begin-->
 <ul class="nav nav-tabs" v-if="isTencentPerson()">
 　　　<router-link :to="{ name: 'statistics1',params:{showPanel:false} }" tag="li" role="presentation"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >统计1</a></router-link>
　　　　　　<router-link :to="{ name: 'statistics2' ,params:{showPanel:false}}" tag="li" role="presentation"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >统计2</a></router-link> 
　　　　　　<router-link :to="{ name: 'statistics3' ,params:{showPanel:false}}" tag="li" role="presentation"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >统计3</a></router-link> 
　　　</ul> 
　　 <!--navtabbar end--> 
　　 <!--内容 begin-->
　　 <router-view></router-view>
</p>

exprot default{　　
　　　　 mounted() {
 this.routerHop();
 },
 updated() {
 //当前页再次点击主路由时重新判断跳转
 var url = this.$route.path;

 // 客户账号登录只显示错误统计分析页面
