JS根据身份证号码计算年龄和性别

function analyzeIDCard(IDCord) {
   var sexAndAge = {};
   //获取用户身份证号码
   var userCard = IDCord;
   //如果用户身份证号码为undefined则返回空
   if(!userCard){
     return sexAndAge;
   }

   // 获取性别
   if(parseInt(userCard.substr(16,1)) % 2 == 1){
     sexAndAge.sex = '1 男'
   }else{
     sexAndAge.sex = '0 女'
   }

   // 获取出生日期
   // userCard.substring(6,10) + "-" + userCard.substring(10,12) + "-" + userCard.substring(12,14)
   var yearBirth = userCard.substring(6,10)】
   var monthBirth = userCard.substring(10,12);
   var dayBirth = userCard.substring(12,14);
   // 获取当前年月日并计算年龄
   var myDate = new Date();
   var monthNow = myDate.getMonth() + 1;
   var dayNow = myDate.getDate();
   var age = myDate.getFullYear() - yearBirth;
   if(monthNow < monthBirth || (monthNow == monthBirth && dayNow < dayBirth)){
     age --;
   }
   // 得到年龄
   sexAndAge.age = age;
   // 返回 性别和年龄
   return sexAndAge;
 }
