新鲜页面中的点击事件冒泡问题

当我在点击赞和转发，和评论的时候会直接跳转到相对应的详情页面。评论和转发直接跳转到详情页可以接受，但是点赞也跳转到详情页有点不适合。所以点赞的时候，要阻止事件冒泡。将 src\components\post下的index.vue修改成如下即可解决点赞时跳转到详情页

<template>
  <div @click="goDetail('commentlist')" class="item-wrap" :class="{detail:type=='detail'}">
    <div class="item-top">
      <avatar :user="mblog.user" class="left-avatar"></avatar>
      <div class="item-right">
        <div class="name">{{mblog.user.screen_name}}</div>
        <div class="time">{{mblog.created_at}}&nbsp;来自{{mblog.source}}</div>
      </div>
    </div>
    <div class="text-content" v-html="formatText(mblog.text)"></div>

      <pics v-if="mblog.pics && mblog.pics.length > 0" :mblog="mblog" />
      <videopart v-else-if="mblog.page_info && mblog.page_info.type =='video'" :vid="mblog.id" :videoData="mblog.page_info"/>
