js从身份证号码获取出生日期、年龄、性别

//获取出生日期
function getBirthday(cardNo) {
    var birthday = cardNo.substring(6, 10) + "-" + cardNo.substring(10, 12) + "-" + cardNo.substring(12, 14);
    return birthday;
}

//获取年龄
function getAge(cardNo) {
    var date = new Date();
    var year = date.getFullYear();
    var month = date.getMonth() + 1;
    var day = date.getDate();
    var age = year - cardNo.substring(6, 10) - 1;
    if (cardNo.substring(10, 12) < month || cardNo.substring(10, 12) == month && cardNo.substring(12, 14) <= day) {
        age++;
    }
    return age;
}

//获取性别
function getSex(cardNo) {
    var sex = "";
    if(parseInt(cardNo.substr(16, 1)) % 2 == 1){
        sex = "男";
    } else {
        sex = "女";
    }
    return sex;
}
