vue路由\导航刷新后:ative\localStorage\url截取参数

<el-menu :default-active="$route.path" router mode="horizontal">
<el-menu-item v-for="route in routes" :key="route.path"
:index="route.path" :class="$route.path==route.path?'is-active':''">{{route.name}}

routes: [
{ path: '/main/kdgadmin', name: '幼儿园管理', },
{ path: '/main/phyex', name: '体测', },
]
css:
.is-active{
background: #a3212f;
border-bottom: 0px solid transparent;
color: #FFFFFF;
}

本地localStorage：
localStorage.Id= response.data.Meta.Id;
localStorage.getItem("Id"),

url截取参数:
path: '/info?ChildId=' + id + '&ChildName=' + childname
ChildId= this.$route.query.ChildId;
