Proper way to get all rows from data table?

mawi5

I have this dataTable:

$('#dtTecnologia').dataTable({
        paging: false,
        searching: false,
        ordering: false,
        scrollY: 177,
        info: false,
        "data": null,
        "columns": [
            { "data": "Tecnologia" }
        ]
    });
}


dtTecnologia = $('#dtTecnologia').DataTable();

And I have a function to add rows:

function addRow(oTecnologia)
{
      oRow =  dtTecnologia.row.add(oTecnologia).draw().node();

      console.log("New data added:");
      console.log(dtTecnologia.row(oRow).data());
      console.log("At index:");
      console.log(dtTecnologia.row(oRow).index());
}

After that, I add some rows:

addRow({TecnologiaId: 1, Tecnologia: "Test 1"});

addRow({TecnologiaId: 2, Tecnologia: "Test 2"});

At this point, I have no problem, but when I try to get all the data from the data table, using either of this ways:

var oData = dtTecnologia .rows().data();
var oData = dtTecnologia.data();

The oData object contains additional data, not just the rows, and I just want the two objects added:

How can I get only the two objects added?

What's the proper way to get the data from dataTable?

Is there a direct way to get it or I have to iterate the dataTable?

Thanks guys

How can I get only the two objects added?

Use dtTecnologia.row.add(oTecnologia).data() to get the data from the new row (although that seems a little pointless since you already have it in oTecnologia).

*This is the data in the object oData:

That is the API instance properties as well as the contents of the instance. Use the toArray() method to convert the API instance to just a plain old array.
