用ASP實現分級許可權控制
  本文實現的是一個帳務管理系統中分級許可權的控制,程式使用ASP和avascript編寫,在裝有IIS4.0的win NT伺服器上運行,速度快,易維護。
權限等級劃分如下:
①、院長和財務科長:不能輸入,可以無限制查詢、統計;
②、副院長:不能輸入,可以查詢、統計其分管部門的帳務;
③、部門領導:不能輸入,可以查詢、統計本部門的帳務;
④、會計:能輸入各部門的帳務(一個會計有時要做幾個部門的帳),只能查詢、統計自己輸入的帳務。
涉及的資料庫和欄位如下
①、JK_USER資料庫及欄位:id(序號),bmid(部門號),username(使用者名稱),pwd(口令),right(許可權值);
②、BM資料庫及欄位:id(序號) ,bmid(部門號);
③、JZPZ資料庫及欄位:id(序號),bm(部門), zgs(子公司),xmz(項目組),xm(項目),sr(收入),zc(支出),szfx(收支方向),szxs(收支形式),
rq(日期),jbr(經辦人),lrr(錄入人),szsm(收支說明);
④、ZGS資料庫及欄位:id(序號),zgs(子公司)name(公司名),bmid(部門編號)。
1.首先進行使用者身份合法性驗證
  將使用者提交的使用者名稱和口令與資料庫JK_USER中的欄位對照對照,以確定其合法性,只有合法的使用者(系統管理員為其開過戶)才可以進入,合法使用者有

四種權限等級,分別賦予“1”、“2”、“3”、“4”四種許可權值。(程式略)。
2.憑證記帳(分級許可權控制)
  憑證記帳功能是專為會計人員服務的,其他人不可以使用,如以非會計人員身份進入憑證錄入介面時,只有“查詢記帳憑證”功能按鈕可見,其它功能

按鈕不可見。錄入的憑證先存放在一個暫存資料表裡,稱為“未記帳憑證庫”,只有運行“憑證記帳”功能後才進入“憑證庫”在“未記帳憑證庫”中的憑證可以

修改。部分程式如下:
'非會計人員進入,不顯示“憑證記帳”和“儲存未記帳憑證”功能按鈕
if (thisPage.firstEntered) then
if session("tright")<> "1" then
button1.hide
button2.hide
end if

'自動填寫時間和操作人

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")

end if

if rst2.RecordCount >0 then

rst2.MoveNext
loop
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.資料查詢(分級許可權控制)
以憑證的欄位為條件進行查詢,在供選條件前有一方框供打“√”,其中“部門“條件必選(程式自動加上),部門內容由程式根據使用者的許可權自動

從資料庫中調用相應值,分公司內容根據所屬部門自動調整,部分程式如下:
……………
'根據許可權值進入相應的查詢介面

set cnn1=server.CreateObject("adodb.connection")
