萬能表單驗(yàn)證插件：Validator.js實(shí)例詳解

表單的驗(yàn)證一直是網(wǎng)頁(yè)設(shè)計(jì)者頭痛的問題，表單驗(yàn)證類 Validator就是為解決這個(gè)問題而寫的，旨在使設(shè)計(jì)者從紛繁復(fù)雜的表單驗(yàn)證中解放出來，把精力集中于網(wǎng)頁(yè)的設(shè)計(jì)和功能上的改進(jìn)上。

Validator是基于JavaScript技術(shù)的偽靜態(tài)類和對(duì)象的自定義屬性，可以對(duì)網(wǎng)頁(yè)中的表單項(xiàng)輸入進(jìn)行相應(yīng)的驗(yàn)證，允許同一頁(yè)面中同時(shí)驗(yàn)證多個(gè)表單，熟悉接口之后也可以對(duì)特定的表單項(xiàng)甚至僅僅是某個(gè)字符串進(jìn)行驗(yàn)證。因?yàn)槭莻戊o態(tài)類，所以在調(diào)用時(shí)不需要實(shí)例化，直接以"類名+.語法+屬性或方法名"來調(diào)用。此外，Validator還提供3種不同的錯(cuò)誤提示模式，以滿足不同的需要。

Validator目前可實(shí)現(xiàn)的驗(yàn)證類型有：
[JavaScript] 版
Validator目前可實(shí)現(xiàn)的驗(yàn)證類型有：
1.是否為空；
2.中文字符；
3.雙字節(jié)字符
4.英文；
5.數(shù)字；
6.整數(shù)；
7.實(shí)數(shù)；
8.Email地址；
9.使用HTTP協(xié)議的網(wǎng)址；
10.電話號(hào)碼；
11.貨幣；

13.郵政編碼；
14.身份證號(hào)碼(1.05增強(qiáng))；
15.QQ號(hào)碼；
16.日期；
17.符合安全規(guī)則的密碼；
18.某項(xiàng)的重復(fù)值；
19.兩數(shù)的關(guān)系比較；
20.判斷輸入值是否在(n, m)區(qū)間；
21.輸入字符長(zhǎng)度限制(可按字節(jié)比較)；
22.對(duì)于具有相同名稱的單選按鈕的選中判斷；
23.限制具有相同名稱的多選按鈕的選中數(shù)目；
24.自定義的正則表達(dá)式驗(yàn)證；
25.文件上傳格式過濾(1.04)
運(yùn)行環(huán)境(客戶端)：
在Windows Server 2003下用IE6.0+SP1和Mozilla Firefox 1.0測(cè)試通過；
在Lunix RedHat 9下的Netscape測(cè)試通過；

對(duì)于客戶端的表單驗(yàn)證，這個(gè)基于JavaScript編寫的Validator基本上都可以滿足，具體可以下載CHM文件：Validator.CHM下載
