前端时间因为项目需要,要对一个产品下所有的附属图片进行分页显示,没考虑ajax一张张请求,所以干脆一次性全部把图片out,然后在载入的时候进行分页,网上很多jquery,property等都实现了但是他们插件的附属功能很多又不需要,而且没必要就为了这么一个功能区引用这个库,为速度考虑吧,当然你服务器好也行,但是其实这个效果不是必须的,但是觉的会常用,所以就包装成类了,供以后使用,也供有需要的人学习使用。
下面只是一个简单的demo,用的话自己可以在编辑页码样式,有默认的格式。不废话了,自己看吧,有注释使用说明。。。类(3kb)使用可以参照demo,不明白使用的可以留言。
以后会慢慢写一些项目开发中常遇到的问题,以及解决方案,和大家学习分享。

IE6不兼容。建议别用gridview插件。热心网友 时间:2022-05-17 01:57
初学的话建议不要用GridView ,它的确很方便,但是过多的内置功能加大了服务器的负担,建议使用Repeater控件 自己写分页!!!!热心网友 时间:2022-05-17 03:32
没用过这种插件啊!
