Node.js通过身份证号验证年龄、出生日期与性别方法示例

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 : "* ", 
  61 : "陕西", 
  62 : "甘肃", 
  63 : "青海", 
  64 : "宁夏", 
  65 : "*", 
  71 : "*", 
  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() ); 
  }   
 });
