datatables with fixedheader: row click function giving error on fixed cols - datatables

Question

I have an on click function storing the row data in the console log
if you click on the first two columns, you'll notice the function returns undefined, however any of the unfrozen columns returns the data object
I know that this has todo with the fact that the fixedcolumns are created in a cloned table, i was wondering if there was any workaround to this?
// Server-side processing with object sourced data
var $table;
$(document).ready(function() {
$table = $('#example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": "/ssp/objects.php",
dom: "<'row'<'col-md-6 'l><'col-md-6 pull-right'>r>t<'row'<'col-md-6'i><'col-md-6'p>>",
"columns": [
{ "data": "first_name" },
{ "data": "last_name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "start_date" },
{ "data": "salary" }
],
scrollY: "600px",
scrollX: "100%",
scrollCollapse: true,
"pageLength": 5,
lengthMenu: [[5, 10, 25, 50 ], [5, 10, 25, 50]],
order: [[ 1, "asc" ]],
} );
new $.fn.dataTable.FixedColumns( $table, {
leftColumns: 2
} );
$table.on("click", "tr",function(){
var aData = $table.row( this ).data();
console.log( aData);
} );
} );
here is my example code in action

Answer 1

You can use fnGetPosition to get information about row index.
From the manual:
This function is functionally identical to fnGetPosition in
DataTables, taking the same parameter (TH, TD or TR node) and
returning exactly the the same information (data index information).
The difference between the two is that this method takes into account
the fixed columns in the table, so you can pass in nodes from the
master table, or the cloned tables and get the index position for the
data in the main table.
Your code needs to be modified as follows:
var fc = new $.fn.dataTable.FixedColumns( $table, {
leftColumns: 2
});
$table.on("click", "tr", function(){
var aData = $table.row(fc.fnGetPosition(this)).data();
console.log(aData);
});
See this example code for demonstration.
