一、验证类

1、数字验证

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)

2.2 短日期，形如 (2003-12-05)

2.3 长时间，形如 (2003-12-05 13:04:06)

3、表单类

3.1 所有的表单的值都不能为空

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

4.2 判断字符由字母和数字组成。

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 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;}
}
return true;
}

3.7 复选框的全选，多选，全不选，反选
<form name=hrong>
<input type=checkbox name=All onclick="checkAll('mm')">全选<br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/><br/>

<input type=checkbox name=All2 onclick="checkAll('mm2')">全选<br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>

</form>

<SCRIPT LANGUAGE="java script">
function checkAll(str)
{
var a = document.getElementsByName(str);
var n = a.length;
for (var i=0; i<n; i++)
a[i].checked = window.event.srcElement.checked;
}
function checkItem(str)
{
var e = window.event.srcElement;
var all = eval("document.hrong."+ str);
if (e.checked)
{
var a = document.getElementsByName(e.name);
all.checked = true;
for (var i=0; i<a.length; i++)
{
if (!a[i].checked){ all.checked = false; break;}
}
}
else all.checked = false;
}
</SCRIPT>

3.8 文件上传过程中判断文件类型
<input type=file onchange="alert(this.value.match(/^(.*)(/.)(.{1,8})$/)[3])">

画图:
<OBJECT
id=S
style="LEFT: 0px; WIDTH: 392px; TOP: 0px; HEIGHT: 240px"
height=240
width=392
classid="clsid:369303C2-D7AC-11D0-89D5-00A0C90833E6">
</OBJECT>
<SCRIPT>
S.DrawingSurface.ArcDegrees(0,0,0,30,50,60);
S.DrawingSurface.ArcRadians(30,0,0,30,50,60);
S.DrawingSurface.Line(10,10,100,100);
</SCRIPT>

写注册表：
<SCRIPT>
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.RegWrite ("HKCU//Software//ACME//FortuneTeller//", 1, "REG_BINARY");
WshShell.RegWrite ("HKCU//Software//ACME//FortuneTeller//MindReader", "Goocher!", "REG_SZ");
var bKey = WshShell.RegRead ("HKCU//Software//ACME//FortuneTeller//");
WScript.Echo (WshShell.RegRead ("HKCU//Software//ACME//FortuneTeller//MindReader"));
WshShell.RegDelete ("HKCU//Software//ACME//FortuneTeller//MindReader");
WshShell.RegDelete ("HKCU//Software//ACME//FortuneTeller//");
WshShell.RegDelete ("HKCU//Software//ACME//");
</SCRIPT>

TABLAE相关(客户端动态增加行列）
<HTML>
<SCRIPT LANGUAGE="JScript">
function numberCells() {
var count=0;
for (i=0; i < document.all.mytable.rows.length; i++) {
for (j=0; j < document.all.mytable.rows(i).cells.length; j++) {
document.all.mytable.rows(i).cells(j).innerText = count;
count++;
}
}
}
</SCRIPT>
<BODY onload="numberCells()">
<TABLE id=mytable border=1>
<TR><TH> </TH><TH> </TH><TH> </TH><TH> </TH></TR>
<TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR>
<TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR>
</TABLE>
</BODY>
</HTML>

１．身份证严格验证：

<script>
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}

function cidInfo(sId){
var iSum=0
var info=""
if(!/^/d{17}(/d|x)$/i.test(sId))return false;
sId=sId.replace(/x$/i,"a");
if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区";
sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2));
var d=new Date(sBirthday.replace(/-/g,"/"))
if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日";
for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11)
if(iSum%11!=1)return "Error:非法证号";
return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")
}

document.write(cidInfo("380524198002300016"),"<br/>");
document.write(cidInfo("340524198002300019"),"<br/>")
document.write(cidInfo("340524197711111111"),"<br/>")
document.write(cidInfo("34052419800101001x"),"<br/>");
</script>

２．验证ＩＰ地址
<SCRIPT LANGUAGE="java script">
function isip(s){
var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}};
var re=s.split(".")
return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false
}

var s="202.197.78.129";
alert(isip(s))
</SCRIPT>

３．加sp1后还能用的无边框窗口！！
<HTML XMLNS:IE>

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="java script">
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{

}

}
else if(("0123456789.").indexOf(keychar)>-1){
window.status = "";
return true;
}
else {
window.status = "Field excepts numbers only";
return false;
}
}

验证ip

str=document.RegExpDemo.txtIP.value;
if(/^(/d{1,3})/.(/d{1,3})/.(/d{1,3})/.(/d{1,3})$/.test(str)==false)

document.RegExpDemo.txtIP.select();
document.RegExpDemo.txtIP.focus();
return;
}
//剔除如 010.020.020.03 前面的0
var str=str.replace(/0(/d)/g,"$1");
str=str.replace(/0(/d)/g,"$1");
window.alert(str);
