這裏一併請教了，大家以後查閱
- function chknum(NUM)
{
var i,j,strTemp;
strTemp= ".0123456789 ";
if ( NUM.length== 0)
return 0
for (i=0;i <NUM.length;i++)
{
j=strTemp.indexOf(NUM.charAt(i));
if (j==-1)
{
return 0;
}
}
return 1;
}
這是判斷數字的 - Validator目前可實現的驗證類型有：
1.是否爲空；
2.中文字符；
3.雙字節字符
4.英文；
5.數字；
6.整數；
7.實數；
8.Email地址；
9.使用HTTP協議的網址；
10.電話號碼；
11.貨幣；
12.手機號碼；
13.郵政編碼；
14.身份證號碼(1.05增強)；
15.QQ號碼；
16.日期；
17.符合安全規則的密碼；
18.某項的重複值；
19.兩數的關係比較；
20.判斷輸入值是否在(n, m)區間；
21.輸入字符長度限制(可按字節比較)；
22.對於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目；
24.自定義的正則表達式驗證；
25.文件上傳格式過濾(1.04新增)。 - <script>
