Twice request ajax

Hi,

I know this question is already ask but I tried to apply the solution but not works for me...

I use the version 1.10.20 and for each request ajax I have twice request, I would have juste one if it possible.

This is my code ->

var tableau = $('#example').DataTable({
columns: enteteColonne,
// Effet de style colonne
"columnDefs": columnDefs,
"orderCellsTop": true,
// gestion de la DOM html
// Doc : https://datatables.net/examples/basic_init/dom.html
dom: '<"g-pa-10 g-pb-0 g-mb-10 g-bg-white"<"row"<"col-xl-7 col-lg-12"<"#actionMenu.g-mb-10 g-mr-10">B><"col-xl-5 col-lg-12"<"#searchColonne.float-right">>>><"row"<"col-md-12 g-mb-10"<"g-pa-10 g-bg-white"<"#titreTableau.col-12">it>><"col-md-12 g-mb-10"<"g-pa-10 g-bg-white"<"row"<"col-md-6"l><"col-md-6"p>>>>>',
select: {
style: 'multi+shift'
},
// Gestion des btn

"initComplete": function(settings, json) {

    if (nouvelleRecherche == true) {
      tableau.rows().nodes().to$().not(".selected").addClass("selected");

      tableau.rows('.selected').select();

      var rowData = tableau.rows().data().toArray();

      manipTableauSelectedPK(rowData,"toutSelectionner");
    }

    // Si la dernière condition nous indique qu'on doit afficher une alerte spécifique à la fin... alors on l'affiche :D
    if (data.hasOwnProperty("affichageAlerteFin") == true) {
      bootbox.alert({
        message: data.messageAlerteFin
      })
    }
  }

});

Thanks.

    Ok, and WHAT is it that does not work for you? Would be great to let us know.

    Please format your code using Markdown (see link underneath the comment box).

    I don't see anything obvious. You have serverSide: true. Any call to the draw() API will cause a SSP ajax request. Do you have an event or other code that might be using draw()?

    Does the double ajax request happen on Datatable load or at some other time.

    Please post a link to your page or a running test case showing the issue so we can take a look.

    Thanks, exactly I use command draw() after and if I comment this part I have just one request, a big thank's that is not easy to see it caused by this...

  • kthorngrenkthorngren Posts: 21,325Questions: 26Answers: 4,949

    The draw() API causes Datatables to refresh the table searching and sorting which, with server side processing, uses an Ajax request to fetch the page data.
