[以下是給甲組同學的作業]

The goal of this homework is to perform form validation, which is considered to be one of the most important missions of JavaScript. Specifically, you are going to design JavaScript code to check the validity of each input field in the following form. Note that:

Be sure to trim all leading and trailing white spaces (both English and big-5) at onBlur events.
You can use string manipulation functions in JavaScript to accomplish the task. You can also use regular expressions if you prefer to do so. Regular expressions are highly recommended since they will save you a lot of troubles.
You can safely assume that the clients are using IE5.

範例表單如下：

英文名字：
格式需求：最少兩個、最多三個英文字，例如
Qualified: "James Bond", "Michael J. Fox", "Lotfi Asker Zadeh"
Not qualified: "", "Roger", "O. J. K. Simpson"
中文名字：
格式需求：最少兩個、最多四個中文字，例如
Qualified: "王傑", "陳水扁", "歐陽菲菲"
Not qualified: "", "張", "湯姆謝立克"
Any white spaces (including the big-5 code for space) between neighboring Chinese characters should be removed at onBlur event.
電子郵件（例如 jang@cs.nthu.edu.tw）：
Qualified: "jang@mathworks.com", "jang@cs.nthu.edu.tw"
Not qualified: "jang", "jang@", "@cs", "jang@cs", "jang@.com", "jang@diva.", "jang@mathworks..com", etc.
個人密碼：
格式需求:
1. Five to eight characters.
2. Not all from 26 English alphabets.
性別： male female
格式需求: must check one of them.
身份證字號：
格式需求:
1. The first character must be converted into uppercase at onBlur event.
2. Must contains the right number of digits.
3. The last digit should follow the checking method described here.
4. 第一個數字代表性別，1 是男，2 是女，因此你的程式碼必須檢查和身份證字號和性別資料的一致性。
信用卡號碼：
格式需求: it must have three dashes and valid 16 digits.
個人網址：
Qualified: "http://www.cs.nthu.edu.tw/~jang", "http://www.mathworks.com", etc
Not qualified: "www.mathworks.com", "http://www.com.", "http://www..com", etc.
意見發表：
格式需求: cannot be empty.

加分項目：

中文大名只能填入大五碼，而不能出現其他英文或數字等。

[以下是給乙組同學的作業]

請根據身份證號碼的規則，利用亂數，一次產生五組有效的身份證號碼，範例表單如下：
請輸入第一個英文字母：
請注意：
1. 輸入的英文字母必須是合格的。
2. 必須將英文字母轉成大寫，再加上九位數字。
3. 必須利用亂數產生，所以每次產生的五組號碼都應該不一樣。
