想了解Ajax+Asp源代码]读取数据库内容的表格(没有用框架)的相关内容吗，在本文为您仔细讲解的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Ajax+Asp源代码]读取数据库内容的表格(没有用框架)，下面大家一起来学习吧。
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.
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.
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.
