注冊頁面index.asp。其中有兩個(gè)輸入域：用戶名和口令，這兩個(gè)輸入域需要客戶機(jī)端的javascript確認(rèn)，以便不把它們作為空白域來傳遞。非考生要想?yún)⒓涌荚嚤仨毾茸?。這個(gè)頁面還要顯示一些錯(cuò)誤信息，如“用戶名或口令錯(cuò)誤”、“請重新選擇一個(gè)用戶名”等。注冊表單中還應(yīng)包含考生一些個(gè)人的信息，如Emai、年齡、教育程度等。登錄后，考生就可以參答考試站點(diǎn)的其它試卷了。

登錄文件register.asp，當(dāng)考生登錄或新注冊后，就顯示這一頁。我們可以利用它來詢問考生的個(gè)人信息。該表單被提交后，轉(zhuǎn)到sendregister.asp頁面。

----------------------------------------------------------------------------------------------------------------

驗(yàn)證和發(fā)送文件sendregister.asp。該頁面從register.asp 中取得表單域的內(nèi)容，查詢數(shù)據(jù)庫驗(yàn)證輸入的用戶名是否已經(jīng)存在，如果存在，則將考生重新引回register.asp頁面，并被提示要求重新選擇用戶名；如果用戶名通過，則輸入的內(nèi)容就被傳遞并插入到數(shù)據(jù)庫中。

sendregister.asp

Set RS_findmember = Application("Conn").Execute(sql_findmember)

response.redirect "register.asp"

選擇試卷頁面default.asp。登錄成功后，進(jìn)入該頁面。在這兒，考生可以選擇的考試科目列表。在本設(shè)計(jì)中，用了001html 和002html兩個(gè)，在實(shí)際應(yīng)用中，可以增加表格以增加考試科目數(shù)。default.asp 要求表格安裝一個(gè)下拉菜單，其中包含科目的列表，然后查詢數(shù)據(jù)庫，從試卷的表格中搜集兩個(gè)域。

default.asp

sql_papers = "select *id, topic from paper sort order by topic asc"

SET RS_papers = Application("Conn").Execute(sql_papers)

' 以下代碼是為了在下拉菜單中顯示結(jié)果.

終于可以參加精英賽了！我們進(jìn)入了試題頁面redirect.asp。它將考生送到實(shí)際生成試題的ASP頁面，如果數(shù)據(jù)庫中沒有所選擇的科目的任何題目，就會顯示錯(cuò)誤信息和返回鏈接。如果數(shù)據(jù)庫有題，則這一頁就被重新引導(dǎo)到exam.asp頁面，考生就可以進(jìn)行在線考試了。

exam.asp是標(biāo)準(zhǔn)試卷頁面，代碼共分兩大部分：計(jì)時(shí)器函數(shù)和本頁查詢選取試題。顯示試題，并以單選按鈕方式供考生答題。從數(shù)據(jù)庫中選擇的試題，本設(shè)計(jì)采用了隨機(jī)函數(shù)，這也是目前題庫生成試卷的通用方式。題目的個(gè)數(shù)設(shè)定為10個(gè)，考生每次回答5個(gè)。時(shí)間限定為20秒，剩余的時(shí)間在屏幕底部的狀態(tài)窗口中顯示。所有的試題都一起顯示出來，然后開始計(jì)時(shí)。時(shí)間和試題個(gè)數(shù)都可以改變。
