前言

大家如果想要知道自己的年龄,出生日期和性别,或者是别人的,给我个身份证号,我就可以知道,其实很简单的,看下面代码。

node.js实现


static validateIdNumberToAgeYear(str){
 let date = new Date();
 let currentYear = date.getFullYear();
 let currentMonth = date.getMonth() + 1;
 let currentDate = date.getDate();
 
 let idxSexStart = str.length == 18 ? 16 : 14;
 let birthYearSpan = str.length == 18 ? 4 : 2;

 let year;
 let month;
 let day;
 let sex;
 let birthday;
 let age;

 //性别
 let idxSex = 1 - str.substr(idxSexStart, 1) % 2; 
 sex = idxSex == '1' ? '女' : '男'; 
 //生日
 year = (birthYearSpan == 2 ? '19' : '') + str.substr(6, birthYearSpan); 
 month = str.substr(6 + birthYearSpan, 2); 
 day = str.substr(8 + birthYearSpan, 2); 
 birthday = year + '-' + month + '-' + day; 
 //年龄
 let monthFloor = (currentMonth < parseInt(month,10) || (currentMonth == parseInt(month,10) && currentDate < parseInt(day,10))) ? 1 : 0;
 age = currentYear - parseInt(year,10) - monthFloor; 

 // console.log("我的出生日期是"+year+"年"+month+"月"+day+"日"+",今年"+age+"岁了"+",性别是"+sex);

 if(age >= 18){
 return true; 
 }
 
 return false;
}

我这里只是做了一个年龄的判断。

利用js也可以实现

1. 自定义js类如下:


// 构造函数,变量为15位或者18位的身份证号码 
function clsIDCard(CardNo) { 
 this.Valid = false; 
 this.ID15 = ''; 
 this.ID18 = ''; 
 this.Local = ''; 
 if (CardNo != null) 
 this.SetCardNo(CardNo); 
} 


// 设置身份证号码,15位或者18位 
clsIDCard.prototype.SetCardNo = function(CardNo) { 
 this.ID15 = ''; 
 this.ID18 = ''; 
 this.Local = ''; 
 CardNo = CardNo.replace(" ", ""); 
 var strCardNo; 
 if (CardNo.length == 18) { 
 pattern = /^\d{17}(\d|x|X)$/; 
 if (pattern.exec(CardNo) == null) 
 return; 
 strCardNo = CardNo.toUpperCase(); 
 } else { 
 pattern = /^\d{15}$/; 
 if (pattern.exec(CardNo) == null) 
 return; 
 strCardNo = CardNo.substr(0, 6) + '19' + CardNo.substr(6, 9) 
 strCardNo += this.GetVCode(strCardNo); 
 } 
 this.Valid = this.CheckValid(strCardNo); 
} 
// 校验身份证有效性 
clsIDCard.prototype.IsValid = function() { 
 return this.Valid; 
} 
// 返回生日字符串,格式如下,1981-10-10 
clsIDCard.prototype.GetBirthDate = function() { 
 var BirthDate = ''; 
 if (this.Valid) 
 BirthDate = this.GetBirthYear() + '-' + this.GetBirthMonth() + '-' 
 + this.GetBirthDay(); 
 return BirthDate; 
} 
// 返回生日中的年,格式如下,1981 
clsIDCard.prototype.GetBirthYear = function() { 
 var BirthYear = ''; 
 if (this.Valid) 
 BirthYear = this.ID18.substr(6, 4); 
 return BirthYear; 
} 
// 返回生日中的月,格式如下,10 
clsIDCard.prototype.GetBirthMonth = function() { 
 var BirthMonth = ''; 
 if (this.Valid) 
 BirthMonth = this.ID18.substr(10, 2); 
 if (BirthMonth.charAt(0) == '0') 
 BirthMonth = BirthMonth.charAt(1); 
 return BirthMonth; 
} 
// 返回生日中的日,格式如下,10 
clsIDCard.prototype.GetBirthDay = function() { 
 var BirthDay = ''; 
 if (this.Valid) 
 BirthDay = this.ID18.substr(12, 2); 
 return BirthDay; 
} 

// 返回性别,1:男,0:女 
clsIDCard.prototype.GetSex = function() { 
 var Sex = ''; 
 if (this.Valid) 
 Sex = this.ID18.charAt(16) % 2; 
 return Sex; 
} 

// 返回15位身份证号码 
clsIDCard.prototype.Get15 = function() { 
 var ID15 = ''; 
 if (this.Valid) 
 ID15 = this.ID15; 
 return ID15; 
} 

// 返回18位身份证号码 
clsIDCard.prototype.Get18 = function() { 
 var ID18 = ''; 
 if (this.Valid) 
 ID18 = this.ID18; 
 return ID18; 
} 

// 返回所在省,例如:上海市、浙江省 
clsIDCard.prototype.GetLocal = function() { 
 var Local = ''; 
 if (this.Valid) 
 Local = this.Local; 
 return Local; 
} 

clsIDCard.prototype.GetVCode = function(CardNo17) { 
 var Wi = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1); 
 var Ai = new Array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2'); 
 var cardNoSum = 0; 
 for (var i = 0; i < CardNo17.length; i++) 
 cardNoSum += CardNo17.charAt(i) * Wi[i]; 
 var seq = cardNoSum % 11; 
 return Ai[seq]; 
} 

clsIDCard.prototype.CheckValid = function(CardNo18) { 
 if (this.GetVCode(CardNo18.substr(0, 17)) != CardNo18.charAt(17)) 
 return false; 
 if (!this.IsDate(CardNo18.substr(6, 8))) 
 return false; 
 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" 
 }; 
 if (aCity[parseInt(CardNo18.substr(0, 2))] == null) 
 return false; 
 this.ID18 = CardNo18; 
 this.ID15 = CardNo18.substr(0, 6) + CardNo18.substr(8, 9); 
 this.Local = aCity[parseInt(CardNo18.substr(0, 2))]; 
 return true; 
} 

clsIDCard.prototype.IsDate = function(strDate) { 
 var r = strDate.match(/^(\d{1,4})(\d{1,2})(\d{1,2})$/); 
 if (r == null) 
 return false; 
 var d = new Date(r[1], r[2] - 1, r[3]); 
 return (d.getFullYear() == r[1] && (d.getMonth() + 1) == r[2] && d 
 .getDate() == r[3]); 
}

2. 页面只需要new出对象,并传递数据验证,并可获得相关数据( 住址 | 出生日期 | 性别 )即可:


$("#cardNo").blur(function(event){ 
 var idCard = $(this).val(); 
 
 var checkFlag = new clsIDCard(idCard); 
 if( !checkFlag.IsValid() ){ 
 alert("身份证错误"); 
 return false; 
 }else{ 
 alert( "出生于: " + checkFlag.GetBirthDate() +" 地区:" + checkFlag.GetLocal() +" sex:" + checkFlag.GetSex() ); 
 } 
 });
