Double entrys in Table after ajax call

Schmakus

Hi there!

With following Code, I have double entrys in my table.
I want to reload the table, if there is new data in the database.
I check for new data with a separate ajax call. If it's true, then I call the function "RefreshDataOnPage"

var table_show_places = $('#table_show_places').DataTable( {
        "order": [ [ 1, 'asc' ]],
        "lengthMenu": [ [10, 15, -1], [10, 15, "All"] ],
        "ajax": {
            "url": "ajax/table.show.places.php",
        },
        "columns": [
            { "data": "id", "orderable": false },
            { "data": "place", "orderable": false }
        ],
        "language": { "url": "js/german.js"},
        "ordering": false
    });
  
  
  function RefreshDataOnPage(){

    table_show_places.ajax.reload( null, false); // user paging is not reset on reload
  }
