Ajax+Asp源代码]读取数据库内容的表格(没有用框架)

80酷酷网    80kuku.com

　　ajax|数据|数据库|源代码

功能:
读取数据库内容的表格.读取数据方式为ajax,分页也是.代码写得不好.呵呵.供一些学习ajax的朋友参考参考.如有不妥请大家跟贴纠正.我会根据大家的提议不断修正代码.
目前还有一个小问题,如果有朋友有兴趣帮我解决一下在下不胜感激
你翻到最后一页的时候如果只有一行会出现空白和undefined.这个问题我试了很多方法一直没有很妥当的解决.
注:下面一些地方出现笑脸表情的是 大写的d
其实很多地方都可以根据asp文件中输出的字符来控制.目前还没有往那方面完善.比如说一列显示多少行等.
Asp页面的代码:
文件名:demo.Asp

'下面这个Sub 是延迟用于调试ajax的loading

If Sec1 <> Sec2 Then

SecCount = SecCount + 1

数据库为access.
数据库文件名:database.mdb
表名:UserData
字段:Id    Name   Sex   Age
id为编号.其他全部为String.发不上来图,自己看加吧.性别也是普通的文本字段,如果需要yes/no.自己修改一下就可以了
