jQuery: Accessing table rows of second and further pages of a datatable

Question

I am retrieving table row data like this from a HTML table.

var descriptions = [];

var testRows = $(\'#tbl\').find(\'tbody\').find(\'tr\');
$this = $(this);         


        

Answer 1

I retrieved the data using fnGetNodes API method.

Correct version (Aug 1 2013)

var descriptions = [];

var _testDesc;
var dt = $("tbl").dataTable();

var dtNodes = dt.fnGetNodes;
var dtNodeCount = dtNodes.length;

for (var i = 0; i < dtNodeCount; i++) {
    var description = $(dtNodes[i].cells[2].innerHTML).val();
    descriptions.push(description);
}

Wrong version ( Jul 31 2013)

var descriptions = [];

var _testDesc;
var dt = $("tbl").dataTable();

var dtElementCollection = dt.DataTable.settings[0].aoData;
var dtECLength = dtElementCollection.length;

for (var i = 0; i < dtECLength; i++) {
    var description = dtElementCollection[i]._aData[2];
    _testDesc = $(description).val();
    descriptions.push(_testDesc);
}
