ASP VBScript 分页函数 by Stabx, 第三版
作用: 
翻页导航, 显示数据请另外处理

说明:
简化简化再简化, 只需输入 '''/// call fPageCount(连接名,每页总数,开始数,号码导航链接数) ///'''
详细如: call fPageCount(rs,50,1,10)
 
本版实现了不需输入 URL 就可以自动获取 URL 的功能
文本框翻页功能也实现了智能化, 不需指定 URL, 前提是客户端没关闭 JS (相信不会有太多人跟我一样, 通常浏览网页都关闭 JS, 只在调试时使用)
本版尽可能的没用 联字符(&), 该字符很费时

导航预览:
首页 上十 上一 81 82 83 84 85 86 87 88 89 90 下一 下十 尾页 转到:___
50篇/页 88/831页 共 41503篇
