javascript或asp实现的判断身份证号码是否正确两种验证方法
具体代码如下：
一、用javascript验证：
复制代码 代码如下:
<script>
function checkIdcard(idcard){
var Errors=new Array(
"验证通过!",
"身份证号码位数不对!",
"身份证号码出生日期超出范围或含有非法字符!",
"身份证号码校验错误!",
"身份证地区非法!"
);
var area={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"}
var idcard,Y,JYM;
var S,M;
var idcard_array = new Array();
idcard_array = idcard.split("");
//地区检验
if(area[parseInt(idcard.substr(0,2))]==null) return Errors[4];
//身份号码位数及格式检验
switch(idcard.length){
case 15:
if ( (parseInt(idcard.substr(6,2))+1900) % 4 == 0 || ((parseInt(idcard.substr(6,2))+1900) % 100 == 0 && (parseInt(idcard.substr(6,2))+1900) % 4 == 0 )){
ereg=/^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}$/;//测试出生日期的合法性
} else {
ereg=/^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}$/;//测试出生日期的合法性
}
if(ereg.test(idcard)) return Errors[0];
else return Errors[2];
break;
case 18:
//18位身份号码检测
//出生日期的合法性检查
//闰年月日:((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))
//平年月日:((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))
if ( parseInt(idcard.substr(6,4)) % 4 == 0 || (parseInt(idcard.substr(6,4)) % 100 == 0 && parseInt(idcard.substr(6,4))%4 == 0 )){
ereg=/^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}[0-9Xx]$/;//闰年出生日期的合法性正则表达式
} else {
ereg=/^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}[0-9Xx]$/;//平年出生日期的合法性正则表达式
}
if(ereg.test(idcard)){//测试出生日期的合法性
//计算校验位
S = (parseInt(idcard_array[0]) + parseInt(idcard_array[10])) * 7
+ (parseInt(idcard_array[1]) + parseInt(idcard_array[11])) * 9
+ (parseInt(idcard_array[2]) + parseInt(idcard_array[12])) * 10
+ (parseInt(idcard_array[3]) + parseInt(idcard_array[13])) * 5
+ (parseInt(idcard_array[4]) + parseInt(idcard_array[14])) * 8
+ (parseInt(idcard_array[5]) + parseInt(idcard_array[15])) * 4
+ (parseInt(idcard_array[6]) + parseInt(idcard_array[16])) * 2
+ parseInt(idcard_array[7]) * 1
+ parseInt(idcard_array[8]) * 6
+ parseInt(idcard_array[9]) * 3 ;
Y = S % 11;
M = "F";
JYM = "10X98765432";
M = JYM.substr(Y,1);//判断校验位
if(M == idcard_array[17]) return Errors[0]; //检测ID的校验位
else return Errors[3];
}
else return Errors[2];
break;
default:
return Errors[1];
break;
}
}
alert(checkIdcard("220183198808081610"))
</script>
二、通过asp代码验证：
复制代码 代码如下:
<%

area = "11,12,13,14,15,21,22,23,31,32,33,34,35,36,37,41,42,43,44,45,46,50,51,52,53,54,61,62,63,64,65,71,81,82,91"
Dim ereg
Set ereg = New regexp
'地区检验
