This article explains the jQuery Ajax paging kkpager plug-in function through example code. Friends who need it can refer to it

Code fragment one:


 <!--分页组件 JS CSS 开始-->
  <!--分页组件 CSS-->
  <link type="text/css" href="/resource/css/kkpager_blue.css" rel="external nofollow" rel="stylesheet" />
  <!--分页组件 JS-->
  <script type="text/javascript" src="/resource/js/kkpager.min.js"></script>
  <script type="text/javascript" src="/resource/js/kkpager.js"></script> 
  <!--分页组件 JS CSS 结束-->

Code fragment two:

The following code: on the original version Modified, because ajax paging cannot update the total number of pages in time

The following is the plug-in kkpager.js code:
