一、验证类
1、数字验证内
1.1 整数
/^(-|+)?d+$/.test(str)
1.2 大于0的整数 （用于传来的ID的验证)
/^d+$/.test(str)
1.3 负整数的验证
/^-d+$/.test(str)
2、时间类
2.1 短时间，形如 (13:04:06)
function isTime(str)
{
var a = str.match(/^(d{1,2})(:)?(d{1,2})2(d{1,2})$/);
if (a == null) {alert('输入的参数不是时间格式'); return false;}
if (a[1]>24 || a[3]>60 || a[4]>60)
{
alert("时间格式不对");
return false
}
return true;
}
2.2 短日期，形如 (2003-12-05)
function strDateTime(str)
{
var r = str.match(/^(d{1,4})(-|/)(d{1,2})2(d{1,2})$/);
if(r==null)return false;
var d= new Date(r[1], r[3]-1, r[4]);
return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]);
}
2.3 长时间，形如 (2003-12-05 13:04:06)
function strDateTime(str)
{
var reg = /^(d{1,4})(-|/)(d{1,2})2(d{1,2}) (d{1,2}):(d{1,2}):(d{1,2})$/;
var r = str.match(reg);
if(r==null)return false;
var d= new Date(r[1], r[3]-1,r[4],r[5],r[6],r[7]);
return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]&&d.getHours()==r[5]&&d.getMinutes()==r[6]&&d.getSeconds()==r[7]);
}
2.4 只有年和月。形如(2003-05,或者2003-5)
2.5 只有小时和分钟,形如(12:03)
3、表单类
3.1 所有的表单的值都不能为空
<input onblur="if(this.value.replace(/^s+|s+$/g,'')=='')alert('不能为空!')">
3.2 多行文本框的值不能为空。
3.3 多行文本框的值不能超过sMaxStrleng
3.4 多行文本框的值不能少于sMixStrleng
3.5 判断单选框是否选择。
3.6 判断复选框是否选择.
3.7 复选框的全选，多选，全不选，反选
3.8 文件上传过程中判断文件类型
4、字符类
4.1 判断字符全部由a-Z或者是A-Z的字字母组成
<input onblur="if(/[^a-zA-Z]/g.test(this.value))alert('有错')">
4.2 判断字符由字母和数字组成。
<input onblur="if(/[^0-9a-zA-Z]/g.test(this.value))alert('有错')">
4.3 判断字符由字母和数字，下划线,点号组成.且开头的只能是下划线和字母
/^([a-zA-z_]{1})([w]*)$/g.test(str)
4.4 字符串替换函数.Replace();
5、浏览器类
5.1 判断浏览器的类型
window.navigator.appName
5.2 判断ie的版本
window.navigator.appVersion
5.3 判断客户端的分辨率
window.screen.height; window.screen.width;
6、结合类
6.1 email的判断。
function ismail(mail)
{
return(new RegExp(/^w+((-w+)|(.w+))*@[A-Za-z0-9]+((.|-)[A-Za-z0-9]+)*.[A-Za-z0-9]+$/).test(mail));
}
6.2 手机号码的验证
6.3 身份证的验证
function isIdCardNo(num)
{
if (isNaN(num)) {alert("输入的不是数字！"); return false;}
var len = num.length, re;
if (len == 15)
re = new RegExp(/^(d{6})()?(d{2})(d{2})(d{2})(d{3})$/);
else if (len == 18)
re = new RegExp(/^(d{6})()?(d{4})(d{2})(d{2})(d{3})(d)$/);
else {alert("输入的数字位数不对！"); return false;}
var a = num.match(re);
if (a != null)
{
if (len==15)
{
var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
else
{
var D = new Date(a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对！"); return false;}

</SCRIPT>
写注册表：
<SCRIPT>
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.RegWrite ("HKCUSoftwareACMEFortuneTeller", 1, "REG_BINARY");

电话号码的验证
要求：
(1)电话号码由数字、"("、")"和"-"构成
(2)电话号码为3到8位
(3)如果电话号码中包含有区号，那么区号为三位或四位
(4)区号用"("、")"或"-"和其他部分隔开
(5)移动电话号码为11或12位，如果为12位,那么第一位为0
(6)11位移动电话号码的第一位和第二位为"13"
(7)12位移动电话号码的第二位和第三位为"13"
根据这几条规则，可以与出以下正则表达式：
(^[0-9]{3,4}-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^([0-9]{3,4})[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)
<script language="javascript">
function PhoneCheck(s) {
var str=s;
var reg=/(^[0-9]{3,4}-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^([0-9]{3,4})[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)/
alert(reg.test(str));
}
</script>
<input type=text name="iphone">
<input type=button onclick="PhoneCheck(document.all.iphone.value)" value="Check">
具有在输入非数字字符不回显的效果，即对非数字字符的输入不作反应。
function numbersonly(field,event){
var key,keychar;
if(window.event){
key = window.event.keyCode;
}
else if (event){
key = event.which;
}
else{
return true
}
keychar = String.fromCharCode(key);
if((key == null)||(key == 0)||(key == 8)||(key == 9)||(key == 13)||(key == 27)){
return true;
}
else if(("0123456789.").indexOf(keychar)>-1){
window.status = "";
return true;
}
else {
window.status = "Field excepts numbers only";
return false;
