js从身份证号中获取出生日期和性别

今天,在做移动端的项目中,按照设计稿的要求,是可以让用户自己输入出生日期的,我还很认真的用了刚刚知道的html5表单的日期类型,本想着终于不用日期插件就可以实现用户选择自己的出生日期了,可结果老大说,把这个表单去掉,要做成从身份证号里边读取用户的出生日期。好吧,高兴了一半,结果...。唉,没办法,只能按照领导的要求来做啊,于是就有了下边的从身份证号中获取出生日期和性别的代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="jquery.min.js"></script>
</head>
<body>
<input type="tel" id="js_Idcard">
<span id="js_birthday"></span>
<script>
$(function(){
function GetBirthdatByIdNo(iIdNo){
var tmpStr = "";
var birthday = $("#js_birthday"); iIdNo = $.trim(iIdNo); if(iIdNo.length == 15){
tmpStr = iIdNo.substring(6, 12);
tmpStr = "19" + tmpStr;
tmpStr = tmpStr.substring(0, 4) + "-" + tmpStr.substring(4, 6) + "-" + tmpStr.substring(6);
sexStr = parseInt(iIdNo.substring(14, 1),10) % 2 ? "男" : "女";
birthday.text(sexStr + tmpStr);
}else{
tmpStr = iIdNo.substring(6, 14);
tmpStr = tmpStr.substring(0, 4) + "-" + tmpStr.substring(4, 6) + "-" + tmpStr.substring(6);
sexStr = parseInt(iIdNo.substring(17, 1),10) % 2 ? "男" : "女";
birthday.text(sexStr + tmpStr);
}
} $("#js_Idcard").blur(function(){
GetBirthdatByIdNo($(this).val());
});
});
</script>
</body>
</html>

另一种从身份证号中获取性别的代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="jquery.min.js"></script>
</head> <body>
<input type="tel" id="js_Idcard">
<span id="js_birthday"></span>
<script>
$(function(){
function go(){
var id = $("#js_Idcard").val();
var last = id[id.length - 2]; if(last % 2 != 0){
$("#js_birthday").text("男");
}else{
$("#js_birthday").text("女");
}
} $("#js_Idcard").blur(function(){
go();
});
});
</script>
</body>
</html>
