使用ASP实现网站的目录树
本来想多翻译些东西出来的,但是最近越来越忙了,以后我尽量多贴些
短小的代码出来,翻译是越来越没空完成了。呵呵。
数据库结构(共使用了两个表)
1。tblCategory
字段名 类型
Root binary 说明树关或开(目录的根)
ID 自动编号 关键字
Sort integer 识别该字段内容的整数(如果root是开状态sort为0)表示显示的目录的顺序
Name text(255)可以包含html中的标识符
HREF text(255) 允许空
2。tblPages
ID 自动编号
Sort integer 关键字
Name text(255)
HREF text(255)
