用ASP實(shí)現(xiàn)分級(jí)權(quán)限控制

用ASP實(shí)現(xiàn)分級(jí)權(quán)限控制
　　本文實(shí)現(xiàn)的是一個(gè)帳務(wù)管理系統(tǒng)中分級(jí)權(quán)限的控制，程序使用ASP和javascript編寫(xiě)，在裝有IIS4.0的win NT服務(wù)器上運(yùn)行，速度快，易維護(hù)。
權(quán)限級(jí)別劃分如下：
①、院長(zhǎng)和財(cái)務(wù)科長(zhǎng)：不能輸入，可以無(wú)限制查詢、統(tǒng)計(jì)；
②、副院長(zhǎng)：不能輸入，可以查詢、統(tǒng)計(jì)其分管部門的帳務(wù)；
③、部門領(lǐng)導(dǎo)：不能輸入，可以查詢、統(tǒng)計(jì)本部門的帳務(wù)；
④、會(huì)計(jì)：能輸入各部門的帳務(wù)（一個(gè)會(huì)計(jì)有時(shí)要做幾個(gè)部門的帳），只能查詢、統(tǒng)計(jì)自己輸入的帳務(wù)。
涉及的數(shù)據(jù)庫(kù)和字段如下
①、JK_USER數(shù)據(jù)庫(kù)及字段：id(序列號(hào)),bmid（部門號(hào)）,username（用戶名）,pwd（口令）,right（權(quán)限值）；
②、BM數(shù)據(jù)庫(kù)及字段:id(序列號(hào)) ,bmid(部門號(hào))；
③、JZPZ數(shù)據(jù)庫(kù)及字段：id(序列號(hào))，bm(部門)， zgs(子公司)，xmz(項(xiàng)目組)，xm（項(xiàng)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(shuō)明)；
④、ZGS數(shù)據(jù)庫(kù)及字段：id（序列號(hào)）,zgs（子公司）name（公司名）,bmid（部門編號(hào)）。
1．首先進(jìn)行用戶身份合法性驗(yàn)證
　　將用戶提交的用戶名和口令與數(shù)據(jù)庫(kù)JK_USER中的字段對(duì)照對(duì)照，以確定其合法性，只有合法的用戶（系統(tǒng)管理員為其開(kāi)過(guò)戶）才可以進(jìn)入，合法用戶有

四種權(quán)限級(jí)別，分別賦予“1”、“2”、“3”、“4”四種權(quán)限值。（程序略）。
2．憑證記帳（分級(jí)權(quán)限控制）
　　憑證記帳功能是專為會(huì)計(jì)人員服務(wù)的，其他人不可以使用，如以非會(huì)計(jì)人員身份進(jìn)入憑證錄入界面時(shí)，只有“查詢記帳憑證”功能按鈕可見(jiàn)，其它功能

按鈕不可見(jiàn)。錄入的憑證先存放在一個(gè)臨時(shí)表里，稱為“未記帳憑證庫(kù)”，只有運(yùn)行“憑證記帳”功能后才進(jìn)入“憑證庫(kù)”在“未記帳憑證庫(kù)”中的憑證可以

修改。部分程序如下：
'非會(huì)計(jì)人員進(jìn)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

3.數(shù)據(jù)查詢（分級(jí)權(quán)限控制）
以憑證的字段為條件進(jìn)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(dòng)加上），部門內(nèi)容由程序根據(jù)用戶的權(quán)限自動(dòng)

從數(shù)據(jù)庫(kù)中調(diào)用相應(yīng)值，分公司內(nèi)容根據(jù)所屬部門自動(dòng)調(diào)整，部分程序如下：
