根据身份证号码获取年龄

function getAgeFromCardId(dataVal) {
    var myDate = new Date();
    var month = myDate.getMonth() + 1;
    var day = myDate.getDate();
    var age = myDate.getFullYear() - dataVal.substring(6, 10) - 1;
    if ((dataVal.substring(10, 12) < month) || (dataVal.substring(10, 12) == month && dataVal.substring(12, 14) <= day)) {
        age++
    }
    return age;

}
