我在开发公司oa系统的时候.想找一个csdn的菜单.可是网上有这样的代码.可是不是基于数据库,也不能按权限管理.我就写了一个.我的这个.只有一个程序文件和一个数据库.文件很少,也很容易查错.但是功能完全实现了!
数据库结构:
table:menu
id
parentid,int,4
menuname,char,20
link,char,50
table:userlevel
id
userid,int,4
menuid,int,4
-------------------------------------程序源文件:menulist.asp------------------------------

conn.open("provider=microsoft.jet.oledb.4.0;data source="+server.mappath("tree.mdb")+";persist security info=false")
