TypeError: aData is undefined

Hi there ,
I'm using datatable with data from firebase , but i have a TypeError aData is undefined
Here is my code

$.fn.dataTableExt.afnFiltering.push(
  function(oSettings, aData, iDataIndex) {
    var fromDateG = document.getElementById('fromDate').value;
    var toDateG = document.getElementById('toDate').value;

    fromDateG = fromDateG.substring(6, 10) + fromDateG.substring(3, 5) + fromDateG.substring(0, 2);
    toDateG = toDateG.substring(6, 10) + toDateG.substring(3, 5) + toDateG.substring(0, 2);
    var datoffromDateG = aData[6].substring(6, 10) + aData[6].substring(3, 5) + aData[6].substring(0, 2);
    var datoftoDateG = aData[7].substring(6, 10) + aData[7].substring(3, 5) + aData[7].substring(0, 2);

    if (fromDateG === "" && toDateG === "") {
      return true;
    } else if (fromDateG <= datoftoDateG && toDateG === "") {
      return true;
    } else if (toDateG >= datoftoDateG && fromDateG === "") {
      return true;
    } else if (fromDateG <= datoffromDateG && toDateG >= datoftoDateG) {
      return true;
    }
    return false;
  }
);
$(document).ready(function() {
  var rootRef = firebase.database().ref().child("users/user3/val");
  var table = $('#ex-table').DataTable({
    dom: 'Bfrtip',
    buttons: [
      'copy', 'csv', 'excel', 'pdf', 'print'
    ]
  });
  rootRef.on("child_added", snap => {
    var dataSet = [snap.child("temp").val(), snap.child("hum").val(), snap.child("date").val()];
    $('#fromDate').change(function() {
      table.rows.add([dataSet]).draw();
    });
    $('#toDate').change(function() {
      table.rows.add([dataSet]).draw();
    });

  });
});

but i have this problem

Hi @soulefa ,

It definitely looks defined in there to me! Is the error definitely coming from that filtering function? I tried it here, having your script for the from and to dates, but the core is the same, and it's not showing that error.

Would you be able to do a similar live example that does show the error, please?

Cheers,

Colin
