不和你们抢了，我有一个更霸道的。可以根据用户角色，和角色权限，得到用户的彩旦树。
采用javabean+javascript+数据库表。实现的

这么多人啊。我干脆贴一个比较简单的版本在这里了。
数据库脚本
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Block]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Block]
GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[EminRight]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[EminRight]
GOCREATE TABLE [dbo].[Block] (
[BlockName] [varchar] (20) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[BlockId] [int] IDENTITY (1, 1) NOT NULL ,
[BlockFatherId] [int] NULL ,
[BlockScript] [varchar] (200) COLLATE Chinese_PRC_CI_AS NULL ,
[BlockOrder] [varchar] (10) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GOCREATE TABLE [dbo].[EminRight] (
[BlockId] [int] NULL ,
[EminId] [varchar] (4) COLLATE Chinese_PRC_CI_AS NULL ,
[RightTag] [char] (1) COLLATE Chinese_PRC_CI_AS NULL ,
[RightId] [decimal](18, 0) IDENTITY (1, 1) NOT NULL
) ON [PRIMARY]
GO
