<div id="app"> 
  <!-- router-view 路由出口, 路由匹配到的组件将渲染在这里 --> 
  <router-view></router-view> 
  </div> 

import Vue from 'vue' 
import VueRouter from 'vue-router' 
Vue.use(VueRouter) 
//引入两个组件 
import home from "./home.vue" 
import game from "./game.vue" 
//定义路由 
const routes = [ 
  { path: "/", redirect: "/home" },//重定向 
  { 
    path: "/home", component: home, 
    children: [ 
      { path: "/home/game/:num", component: game } 
    ] 
  } 
] 
//创建路由实例 
const router = new VueRouter({routes}) 
 
new Vue({ 
  el: '#app', 
  data: { 
    id:123, 
  }, 
  methods: { 
  }, 
  router 
})
