我正在使用jQuery DataTables，我的JavaScript代码如下所示：

$(document).ready(function() {
   var tbl = $('#table_tabl').DataTable({
      responsive: true,
      "oLanguage": {
         "sUrl": "<?php  echo RP_LANG ?>fr_FR.txt",
      },
      "processing": true,
      "serverSide": true,
      ajax: "<?php  echo RP_SSP ?>server_processing_reservTables.php", // I want to add a parmeter to it dynamically when a select element is selected 
      "aoColumnDefs": [{
         "aTargets": [3],
         "mData": 3,
         "mRender": function(data, type, full) {
            return '<div style="text-align:center;"><a href="RestaurantReservation/reserverTable/' + data + '" title="R&eacute;server"><span class="mif-lock icon"></span></a></div>';
         }
      }],
      "aLengthMenu": [
         [10, 25, 50, 100, -1],
         [10, 25, 50, 100, "Tout"]
      ]
   });
});

我想根据选择元素的选择值过滤此dataTable：

$("#select_id").on("change", function(){
    // set the ajax option value of the dataTable here according to the select's value
});

如何设置ajax的选项的值dataTable在on_change该事件select根据所选项目选择的元素？
