有的时候我真的想钻到电脑里面去

然后一刀戳死 bug
关于 elementUI+vue 导航栏跳不到对应的路由，求救

<template> <el-container style="height: 500px; border: 1px solid #eee"> <el-aside width="200px" style="background-color: rgb(238, 241, 246)"> <el-menu class="el-menu-vertical-demo" :default-active="defaultActive" router> <el-submenu :index="college.collegeId" v-for="college in show.college"> <template slot="title"> <i class="el-icon-location"></i> <span>{{college.collegeName}}</span> </template> <el-menu-item :index="professional.professionalId" v-for="professional in college.professionalList"> {{professional.professionalName}} </el-menu-item> </el-submenu> </el-menu> </el-aside> <el-container> <el-main> <router-view></router-view> </el-main> </el-container> </el-container> </template> <script> export default { name: "aside1", data() { 略 }, computed: { defaultActive: function(){ return this.$route.path.replace('/', ''); } }, } </script> 

这是 router 的

import Vue from 'vue' import Router from 'vue-router' Vue.use(Router) const collegePage = r => require.ensure([], () => r(require('@/page/collegePage')), 'collegePage'); const routes = [ { path: '/', children:[ { path: '/:id', component: collegePage } ] },{ path:'/:id', component:collegePage } ] export default new Router({ mode:'history', routes, strict: process.env.NODE_ENV !== 'production', }) 

数据都可以显示，url 地址也的确变成了 http://localhost:8080/0201
但是主题就是显示不出来
