Js 根据身份证号获取年龄-性别

参考：http://www.tuicool.com/articles/J7r2ien

方式一：

 $scope.GetAgeAndSexByIDNum = function (IdCardNO)
    {
        // 身份证号码为15位或者18位，15位时全为数字，18位前17位为数字，最后一位是校验位，可能为数字或字符X  
        var reg = /(^d{15}$)|(^d{18}$)|(^d{17}(d|X|x)$)/;
        if (reg.test(IdCardNO) === false)
        {
            alert("身份证号输入不合法");
            return false;
        }
        var date = new Date();
        var yearfull = date.getFullYear();
        if (IdCardNO.length == 18)//18位身份证号处理
        {
            var birthyear = IdCardNO.substring(6, 10);
            var month = IdCardNO.substring(10, 12);
            var day = IdCardNO.substring(12, 14);
            var age = yearfull - birthyear;
            var sexValue = IdCardNO.substring(16, 17);
            var sex = (sexName % 2 == 0 ? "女" : "男");
            if (sex.toString() == "女")
                sexValue = "2";
            if (sex.toString() == "男")
                sexValue = "1";
            else sexValue = "3";
            $scope.applyForm.Age = age;

            document.getElementById("sex").value = sexValue;
            $scope.patient.sex = sex;
        }
        if (IdCardNO.length == 15)//15位身份证号处理
        {
            var birthDay = "";
            birthDay = IdCardNO.substring(6, 12);
            birthDay = "19" + birthDay;
            birthDay = birthDay.substring(0, 4);// + "-" + birthDay.substring(4, 6) + "-" + birthDay.substring(6)
            var age = yearfull - birthDay;//年龄
            var sex = parseInt(birthDay.substring(14, 1), 10) % 2 ? "男" : "女";//性别
            var sexValue = "";
            if (sex.toString() == "女")
                sexValue = "2";
            if (sex.toString() == "男")
                sexValue = "1";
            else sexValue = "3";
            $scope.applyForm.Age = age;
            document.getElementById("sex").value = sexValue;
            $scope.patient.sex = sex;
        }
    };

    $(function(){

            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);

                birthday.text(sexStr + tmpStr);
            }
        }

    $("#js_Idcard").blur(function(){
        GetBirthdatByIdNo($(this).val());
    });
});
