百度一搜就能搜到很多身份证校验的例子,这个是最近做项目参考百度文库的demo修改后的
一,js:
//身份验证
function checkIdCard(idCard){
var sexId;
var sexText;
var age;
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 Y, JYM;
var S, M;
var idcard_array = new Array();
idcard_array = idCard.split("");
if (area[parseInt(idCard.substr(0, 2))] == null){
return Errors[1];
}
if(18!=idCard.length){
return Errors[4];
}
if(18==idCard.length){
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[3];
}
}else{
return Errors[2];
}
var year = idCard.substring(6,10);
var month = idCard.substring(10,12);
var day = idCard.substring(12,14);
var temp_date = new Date(year,parseFloat(month)-1,parseFloat(day));
if(temp_date.getFullYear()!=parseFloat(year)
||temp_date.getMonth()!=parseFloat(month)-1
||temp_date.getDate()!=parseFloat(day)){
return Errors[2];
}
return 0;
}
return 0;
}
二,页面中引用
if(checkIdCard(idCard)!="0"){
$.dialog({type: "warn", content:checkIdCard(idCard), modal: true, autoCloseTime: 3000});
return false;
}
