 用ASP+XML实现CSDN的菜单(数据库),可分权限管理
|
| 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------------------------------
<%'-------------------------------''源创商务策划有限公司-OA系统'模块名称：可权限控制的菜单'-------------------------------'
set conn = Server.CreateObject("ADODB.Connection")conn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.mappath("tree.mdb")+";Persist Security Info=False")%>
