用ASP實現(xiàn)分級權限控制
本文實現(xiàn)的是一個帳務管理系統(tǒng)中分級權限的控制，程序使用ASP和javascript編寫，在裝有IIS4.0的win NT服務器上運行，速度快，易維護。
權限級別劃分如下：
①、院長和財務科長：不能輸入，可以無限制查詢、統(tǒng)計；
②、副院長：不能輸入，可以查詢、統(tǒng)計其分管部門的帳務；
③、部門領導：不能輸入，可以查詢、統(tǒng)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(tǒng)計自己輸入的帳務。
涉及的數(shù)據(jù)庫和字段如下
①、JK_USER數(shù)據(jù)庫及字段：id(序列號),bmid（部門號）,username（用戶名）,pwd（口令）,right（權限值）；
②、BM數(shù)據(jù)庫及字段:id(序列號) ,bmid(部門號)；
③、JZPZ數(shù)據(jù)庫及字段：id(序列號)，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(jīng)辦人),lrr（錄入人），szsm(收支說明)；
④、ZGS數(shù)據(jù)庫及字段：id（序列號）,zgs（子公司）name（公司名）,bmid（部門編號）。
1．首先進行用戶身份合法性驗證
將用戶提交的用戶名和口令與數(shù)據(jù)庫JK_USER中的字段對照對照，以確定其合法性，只有合法的用戶（系統(tǒng)管理員為其開過戶）才可以進入，合法用戶有
四種權限級別，分別賦予“1”、“2”、“3”、“4”四種權限值。（程序略）。
2．憑證記帳（分級權限控制）
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界面時，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臨時表里，稱為“未記帳憑證庫”，只有運行“憑證記帳”功能后才進入“憑證庫”在“未記帳憑證庫”中的憑證可以
修改。部分程序如下：
'非會計人員進入，不顯示“憑證記帳”和“保存未記帳憑證”功能按鈕
if (thisPage.firstEntered) then
if session("tright")<> "1" then
button1.hide
button2.hide
end if

3.數(shù)據(jù)查詢（分級權限控制）
以憑證的字段為條件進行查詢，在供選條件前有一方框供打“√”，其中“部門“條件必選（程序自動加上），部門內(nèi)容由程序根據(jù)用戶的權限自動
從數(shù)據(jù)庫中調(diào)用相應值，分公司內(nèi)容根據(jù)所屬部門自動調(diào)整，部分程序如下：

應用以上程序，可以根據(jù)用戶的權限，按照用戶的要求實行訂制查詢，該系統(tǒng)在win NT、IIS4.0和win98、PWS上運行通過。
