用ASP实现分级权限控制
本文实现的是一个帐务管理系统中分级权限的控制，程序使用ASP和javascript编写，在装有IIS4.0的win NT服务器上运行，速度快，易维护。
权限级别划分如下：
①、院长和财务科长：不能输入，可以无限制查询、统计；
②、副院长：不能输入，可以查询、统计其分管部门的帐务；
③、部门领导：不能输入，可以查询、统计本部门的帐务；
④、会计：能输入各部门的帐务（一个会计有时要做几个部门的帐），只能查询、统计自己输入的帐务。
涉及的数据库和字段如下
①、JK_USER数据库及字段：id(序列号),bmid（部门号）,username（用户名）,pwd（口令）,right（权限值）；
②、BM数据库及字段:id(序列号) ,bmid(部门号)；
③、JZPZ数据库及字段：id(序列号)，bm(部门)， zgs(子公司)，xmz(项目组)，xm（项目），sr（收入），zc(支出)，szfx(收支方向),szxs(收支形式),
rq(日期),jbr(经办人),lrr（录入人），szsm(收支说明)；
④、ZGS数据库及字段：id（序列号）,zgs（子公司）name（公司名）,bmid（部门编号）。
1．首先进行用户身份合法性验证
将用户提交的用户名和口令与数据库JK_USER中的字段对照对照，以确定其合法性，只有合法的用户（系统管理员为其开过户）才可以进入，合法用户有
四种权限级别，分别赋予“1”、“2”、“3”、“4”四种权限值。（程序略）。
2．凭证记帐（分级权限控制）
凭证记帐功能是专为会计人员服务的，其他人不可以使用，如以非会计人员身份进入凭证录入界面时，只有“查询记帐凭证”功能按钮可见，其它功能
按钮不可见。录入的凭证先存放在一个临时表里，称为“未记帐凭证库”，只有运行“凭证记帐”功能后才进入“凭证库”在“未记帐凭证库”中的凭证可以
修改。部分程序如下：
'非会计人员进入，不显示“凭证记帐”和“保存未记帐凭证”功能按钮
if (thisPage.firstEntered) then
if session("tright")<> "1" then
button1.hide
button2.hide
end if

Textbox7.value=year(date) & "-" & month(date) & "-" & day(date)
Textbox9.value =session("username")
set cnn1=server.CreateObject("adodb.connection")
set rst1=server.CreateObject("adodb.recordset")
cnn1.CursorLocation=3
cnn1.ConnectionTimeout =30
cnn1.Open "DSN=jky"
rst1.Open "select * from bm ",cnn1,1,1,adcmdtext
if rst1.RecordCount >0 then
RST1.MoveFirst
Id=rst1.Fields("id")
do while not rst1.EOF
Listbox3.addItem rst1.Fields("bmName"),cint(rst1.Fields("id"))
“Response.Write rst1.Fields("bmname") & rst1.Fields("id")
rst1.MoveNext
loop
end if
rst1.Close
rst1.Open "select zgsname from zgs where bmid=" & id,cnn1,1,1,adcmdtext
if rst1.RecordCount >0 then

end if

end if
end function

do while i>-1
call Listbox4.removeItem(i)

set cnn2=server.CreateObject("adodb.connection")
set rst2=server.CreateObject("adodb.recordset")
cnn2.CursorLocation=3
cnn2.ConnectionTimeout =30
cnn2.Open"DSN=jky"
rst2.Open "select zgsName from zgs where bmid=" & id,cnn2,1,1,adcmdtext
if rst2.RecordCount >0 then

rst2.MoveNext

end if

end sub
sub button2_onclick
set cnn5=server.CreateObject("adodb.connection")
cnn5.CursorLocation=3
cnn5.ConnectionTimeout =30
cnn5.Open"DSN=jky"
cnn5.Execute "insert into jzpz(bm,zgs,xmz,xm,sr,zc,szfx,szxs,rq,jbr,lrr,szsm) select bm,zgs,xmz,xm,sr,zc,szfx,szxs,rq,jbr,
lrr,szsm from wjzpz where lrr=“" & session("username") & "“"
cnn5.Execute "delete from wjzpz where lrr=“" & session("username") & "“"
end sub
3.数据查询（分级权限控制）
以凭证的字段为条件进行查询，在供选条件前有一方框供打“√”，其中“部门“条件必选（程序自动加上），部门内容由程序根据用户的权限自动
从数据库中调用相应值，分公司内容根据所属部门自动调整，部分程序如下：
……………
