How can i use ajax ,data filter outside datatable there is any api ??

ShaikhAhmed

My table columns generate by dynamically .. i want to map my json response with datatable
- how can i use Ajax dataFilter: function(data){} outside my Ajax request.
- i want to use this AJAX method in my code where i put this

dataFilter: function(data){
                var json = jQuery.parseJSON( data );
                var resellerreponce = json.searchResults;
                json.data = resellerreponce.List;
                        json.recordsFiltered = resellerreponce.sCount;                                            
                        json.recordsTotal =resellerreponce.ResultsCount;  
                    return JSON.stringify( json );       
               }

// This is my actual code for dynamic columns

$.ajax({
                  url: "Abc.do?action=Items",
                  success: cb_func
                });
              });


    function getData(cb_func) {               
            getData(function (data) {
             Jdata = data.searchResults.Summary;
                  var columnNames = Object.keys(Jdata[0]);
                  for (var i in columnNames) {
                      columns.push({
                          data: columnNames[i],
                      title: columnNames[i]
                    });

            $('#example').DataTable({
                data: Jdata,
                columns: columns      

                  });
            });
