Vue编程式跳转的实例代码详解

<template>
 <ul class = "prolist">
  <!-- //产品 -->
  <!-- :to = "/detail/item.id" -->
  <!-- 声明式跳转 :to = "{ name: 'detail',params: { id: item.id } }" -->
  <!-- <router-link :to = "{ name: 'detail',params: { id: item.id } }" tag = "li" class = "proitem" v-for="(item,index) of iss" :key='index'>
   <div class = "itemimg">
    <img :src="item.images.small" :alt="item.alt">
   </div>
   <div class = "iteminfo">
    <h3>{{ item.title }}</h3>
    <div class = "directors">
     <span v-for="(itm,idx) of item.directors" :key="idx">
      {{ itm.name }}/
     </span>
    </div>
    <Rating :rating='(item.rating.average / 2).toFixed(1)' />
   </div>
  </router-link> -->

  <!-- 编程式跳转 -->
  <!-- @click="godetail(item.id) -->
  <li class = "proitem" v-for="(item,index) of iss" @click="goDetail(item.id)" :key='index'>
