The ID card can identify a person's information. Let's introduce how to use js to obtain the age and gender of the person concerned through the ID card number. 

<script>
function IdCard(UUserCard,num){
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));
</script>

Let me share with you a piece of code about obtaining a person’s age and gender through their ID number

The code example is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="http://www.jb51.net/" />
<title>脚本之家</title>
<script type="text/javascript"> 
function discriCard(UUserCard)
{ 
UUserCard.substring(6,10)+"-"+UUserCard.substring(10,12)+"-"+UUserCard.substring(12,14); 
//获取性别 
if(parseInt(UUserCard.substr(16,1))%2==1) 
{ 
alert("男"); 
//是男则执行代码 ... 
} 
else 
{ 
alert("女"); 
//是女则执行代码 ... 
} 
//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++; 
} 
alert(age); 
//年龄 age 
} 
window.onload=function()
{
var txt=document.getElementById("txt");
var bt=document.getElementById("bt");
bt.onclick=function(){discriCard(txt.value);}
}
</script>
</head>
<body>
<input type="text" id="txt" />
<input type="button" value="点击获取信息" id="bt" />
</body>
</html>

The above code implements our requirements. Enter the ID number in the text box, and then click the button to pop up the age and gender.
