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

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

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 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;}

}

return true;

}

3.7 复选框的全选，多选，全不选，反选

</form>

<scrīpt LANGUAGE="java scrīpt">

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;

}

</scrīpt>

3.8 文件上传过程中判断文件类型

画图:

<OBJECT

id=S

height=240

width=392

class>

</OBJECT>

<scrīpt>

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);

</scrīpt>

写注册表：

<scrīpt>

var WshShell = Wscrīpt.CreateObject("Wscrīpt.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\\");

Wscrīpt.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\\");

</scrīpt>

TABLAE相关(客户端动态增加行列）

<HTML>

<scrīpt LANGUAGE="Jscrīpt">

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++;

}

</scrīpt>

</TABLE>

</BODY>

</HTML>

１．身份证严格验证：

<scrīpt>

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;

sa");

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/>");

</scrīpt>

２．验证ＩＰ地址

<scrīpt LANGUAGE="java scrīpt">

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))

</scrīpt>

３．加sp1后还能用的无边框窗口！！

<IE:Download />

<title>Chromeless Window</title>

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}$)|(^0{0,1}13[0-9]{9}$)

<scrīpt language="java scrīpt">

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));

}

</scrīpt>

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;

}

验证ip

str=document.RegExpDemo.txtIP.value;

if(/^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$/.test(str)==false)

{

window.alert('错误的IP地址格式');

document.RegExpDemo.txtIP.select();

document.RegExpDemo.txtIP.focus();

return;

}

if(RegExp.$1<1 || RegExp.$1>254||RegExp.$2<0||RegExp.$2>254||RegExp.$3<0||RegExp.$3>254||RegExp.$4<1||RegExp.$4>254)

{

window.alert('错误的IP地址');

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);
