基于vue.js的分页插件详解

<div class="page-bar" v-else> 
 <ul> 
  <li style="width: 11%" v-if="showFirst"> 
  <a v-on:click="cur--"> 
   <<</a>

  <li v-for="index in indexs" v-bind:class="{ 'active': cur == index}"> 
  <a v-on:click="btnClick(index)">{{index}}</a> 
  </li> 
  <li style="width: 11%" v-if="showLast"><a v-on:click="cur++"> >></a></li> 
  <li style="width: 22%;margin-left: 7%"><a>共<i>{{all}}</i>页</a></li> 
 </ul>
