js校验经典例子

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+))*\-AT-[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

全选

全选

function checkAll(str)

{

var a = document.getElementsByName(str);

var n = a.length;

for (var i=0; ia[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{

if (!a[i].checked){ all.checked = false; break;}

}

}

else all.checked = false;

}

3.8 文件上传过程中判断文件类型

-------------------------------------------------------------------------------------

１．身份证严格验证：

２．验证ＩＰ地址

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))

３．加sp1后还能用的无边框窗口！！

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

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));
