Vue全局分页组件的实现代码

需求

一个监控控制台界面，有成千上万条表格数据，需要做一个全局分页组件，支持调整每页显示数目、总页数、当前页数、前进后退、自由跳转页数。

字段

原型

预期长酱紫（不要嫌丑！毕竟是后台控制台！）

代码

html

<template>
  <div class="paging-content clearfix">
    <div class="fl">
      总共<b> {{total}} </b>条 
      <select v-model="limit">
        <option>10</option>
        <option>20</option>
        <option>30</option>
        <option>40</option>
        <option>50</option>
        <option>100</option>
      </select>条/页
    </div>
    <div class="fr paging-box">
      <a v-if="+no>1" class="fa fa-angle-double-left" @click="goToPage(1)"></a>
      <a v-if="+no<=1" class="fa fa-angle-double-left"></a>
      <a v-if="+no>1" class="fa fa-angle-left" @click="goToPage(+no - 1)"></a>
      <a v-if="+no<=1" class="fa fa-angle-left"></a>
      <a v-if="+no-2>1">...</a>
