Cannot reinitialise DataTable - dynamic data for datatable


I have a datatable showing all employees. It is working fine for all employees on document.ready. I have a select tag containing the type of employees like 'project_manager' & 'team_leader' , and on change of employee type I am calling a function get_employees(emp_type) and passing the selected employee type.

It is getting desired and proper data in ajax response, but throwing warning

DataTables warning: table id=example - Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3

I tried to destroy it, but no luck.

also tried for

$('#example').dataTable().fnClearTable();
$('#example').dataTable().fnDestroy();

it is clearing table and showing newly appended data, but adding new sort images with column name every time.

Here is my code snippet.

$(document).ready(function() {
            get_employees('all');
        });

        function get_employees(emp_type)
        {
            $.ajax({
                url: '../ajax_request.php',
                type: "POST",
                data: {
                    action: "admin_get_all_employees",
                    type: emp_type
                },
                success: function(response) {
                    var response = jQuery.parseJSON(response);

                    // $('#example').destroy(); tried this but haven’t worked

                    $('#example').dataTable({
                        "aaData": response.data,
                    });
                }
            });
        }

Thanks in advance.


Solution

  • In the current version of DataTables (1.10.4) you can simply add destroy:true to the configuration to make sure any table already present is removed before being re-initialised.

    $('#example').dataTable({
        destroy: true,
        aaData: response.data
    });
