本文我们主要和大家分享JS实现根据出生日期得到年龄方法，希望能帮助到大家。
JavaScript//JS根据出生日期 得到年龄 //参数strBirthday已经是正确格式的2017-12-12这样的日期字符串 function jsGetAge(strBirthday) {
var returnAge;
var strBirthdayArr=strBirthday.split("-");
var birthYear = strBirthdayArr[0];
var birthMonth = strBirthdayArr[1];
var birthDay = strBirthdayArr[2];
var d = new Date();
var nowYear = d.getYear();
var nowMonth = d.getMonth() + 1;
var nowDay = d.getDate();
if(nowYear == birthYear)
{
returnAge = 0;//同年 则为0岁
}
else
{
var ageDiff = nowYear - birthYear ; //年之差
if(ageDiff > 0)
{
if(nowMonth == birthMonth)
{
var dayDiff = nowDay - birthDay;//日之差
if(dayDiff < 0)
{
returnAge = ageDiff - 1;
}
else
{
returnAge = ageDiff ;
}
}
else
{
var monthDiff = nowMonth - birthMonth;//月之差
if(monthDiff < 0)
{
returnAge = ageDiff - 1;
}
else
{
returnAge = ageDiff ;
}
}
}
else
{
returnAge = -1;//返回-1 表示出生日期输入错误 晚于今天
}
}
return returnAge;//返回周岁年龄 }

if(num==1){
//获取出生日期
birth=UUserCard.substring(6, 10) + "-" + UUserCard.substring(10, 12) + "-" + UUserCard.substring(12, 14);
return birth;
}
if(num==2){
//获取性别
if (parseInt(UUserCard.substr(16, 1)) % 2 == 1) {
//男
return "男";
} else {
//女
return "女";
}
}
if(num==3){
//获取年龄
var myDate = new Date();
var month = myDate.getMonth() + 1;
var day = myDate.getDate();
var age = myDate.getFullYear() - UUserCard.substring(6, 10) - 1;
if (UUserCard.substring(10, 12) < month || UUserCard.substring(10, 12) == month && UUserCard.substring(12, 14) <= day) {
age++;
}
return age;
}
}
alert (IdCard('142223198503226111',3));
alert (IdCard('142223198503226111',2));
alert (IdCard('142223198503226111',1));
