function check_empty_2(event) {

if (document.getElementById('reg_nama').value == "" ||     document.getElementById('reg_email').value == "" || document.getElementById('reg_no').value == "" || document.getElementById('reg_rumah').value == "" ) {
 alert("Harap isi semua bidang !");
} else {
document.getElementById('reg_rfid').style.display = "none";
document.getElementById('alert_rfid').style.display = "block";
$('html, body').animate({

   alert("Harap isi semua bidang !");
  } else {
    document.getElementById('reg_rfid').style.display = "none";
    document.getElementById('alert_rfid').style.display = "block";
    $('html, body').animate({
        scrollTop: $("#alert").offset().top - 150
    });
  }
  event.preventDefault();
  });
});
