//1、創(chuàng)建路由組件
  const Link1={template:'#link1'};
  const Link2={template:'#link2'};
  const Link3={template:'#link3'};
  //2、定義路由映射
  const routes=[
    {
      path:'/link1',       //定義相對路徑
      component:Link1,      //定義頁面的組件
      children:[
        {
          path:'intro',      //子路由/link1/intro
          component:{template:'#ariesIntro'},
          name:'ariesIntro',    //為路由命名
        },
        {
          path:'feature',
          component:{template:'#ariesFeature'},
        },
        {path:'/',redirect:'intro'}
      ]
    },
    {path:'/link2',component:Link2},
    {path:'/link3',component:Link3},
    {path:'/',redirect:'/link1'}        //配置根路由，使其重定向到/link1
  ];
  //3、創(chuàng)建router實(shí)例
  const router = new VueRouter({
    routes                   //縮寫，相當(dāng)于 routes: routes
  });
  // 4、 創(chuàng)建和掛載根實(shí)例。
  const app = new Vue({
    router
  }).$mount('#app');              //掛載到id為app的div

  <div class="col-lg-offset-2 col-lg-2">
    <!-- 使用 router-link 組件來導(dǎo)航. -->
    <!-- 通過傳入 `to` 屬性指定鏈接. -->
    <router-link class="list-group-item" :to="{name:'ariesIntro'}">白羊座</router-link>
    <router-link class="list-group-item" to="/link2">處女座</router-link>
    <router-link class="list-group-item" to="/link3">金牛座</router-link>
  </div>
  <div class="col-lg-6">
    <div class="panel">
      <div class="panel-body">
        <!-- 路由出口，路由匹配到的組件將渲染在這里 -->
        <router-view></router-view>
      </div>
    </div>
  </div>

  <template id="link1">
    <div>
      <h3>白羊座</h3>
      <ul class="nav nav-tabs">
        <li class="active">

      <div class="tab-content">

  this.$router.push('/cart?goodsId=123')
}

<span>商品ID：{{$route.query.goodsId}}</span>
