最近由于项目的需要，做了一个基于JQuery的表格分页插件封装，部分源码来源百度，经由自己封装完成。
下面是具体代码和说明，仅供参考。第一步可以先将我的HTML，CSS，JS这三部分的代码创建好后先运行看看，下图是文件目录展示。

好了，到了这里如果你完成了创建并且运行可以看到效果如下图所示（如果你想自己研究源码，那么下面就可以先不看了--代码逻辑分析）。
下面开始解释代码的运行逻辑。
先看到HTML中下面代码（利用隐藏域存储值）
<input type=‘hidden‘ id=‘current‘ /> /*存储当前页码的值*/
<input type=‘hidden‘ id=‘show‘ /> /*存储页面显示的行数*/
接下来可以看到
<script type="text/javascript">
$(function(){
//page(table的ID,隐藏域ID1(存储当前页的页数),隐藏域ID2(存储一页显示的数量),分页组件ID,A标签默认类(类名自定义),选择时的类(设置活动时的样式类),一页显示的 个数,table的含有th的tr数量)
page(‘#y1‘,‘#current‘,‘#show‘,‘#page_nav_y1‘,‘.y1_page‘,‘active_page‘,10,1);
});
</script>
上面参数我都做了相关的注释，如果没能看懂，欢迎提问。
