Need help while exporting to excel with dynamic fileName and sheetName

roverma2912

Hi
I have a main page on which i have a datatable, on this i have added a custom button from which i will perform a ajax call and open a pop-up using bootstrap Modal. On this pop-up i am taking fileName and sheetName from the user and there is a button to submit.

Now i am stuck i am not getting how to map the submit button click functionality directly to excel button of buttons Extension with fileName and sheetName.

I can access the datatable object on the pop-up page.

Datatable configuration are:

$.extend(true, $.fn.dataTable.defaults, {
      "processing": true,
      "language": {
        "processing": '<span class="fa fa-refresh fa-spin" aria-hidden="true"></span> Loading Data'
      },
      "autoWidth": false,
      "scrollX": true,
      "buttons": [{
        extend: 'excel',
        className: 'btn-sm',
        text: '<span class="glyphicon glyphicon-download-alt" aria-hidden="true"></span>',
        action: function(e, dt, button, config) {
          exportModule.currentDatatable = dt;
          $.ajax({
            url: "/exportDataTable",
            type: "POST",
            success: function(data) {
              $("#mainpageDiv").empty().append(data);
            },
            error: function() {
              alert("Was unable to reach export server.");
            }
          });
        }
      }],


      Pop - up JS is: $('#exportButton').click(function() {
          var dt = exportModule.currentDatatable;
          var fileNameString = $("#filenameText").val();
          var sheetNameString = $("#sheetNameText").val();
          var selectedExport = getSelectedExport();
          switch (selectedExport) {
            case "exportXLS":

              dt.button.buttons({
                extend: 'excelHtml5',
                filename: "fileNameString",
                action: function(e, dt, node, config) {
                  // Do custom processing
                  // ...

                  // Call the default csvHtml5 action method to create the CSV file
                  $.fn.dataTable.ext.buttons.excelHtml5.action.call(this, e, dt, node, config);
                }
              });


          }

          break;
          case "exportCSV":

        }
      });
