How do I intercept an ajax call and pass additional parameters fnParams fnServerData details

gc_retrogress

Here is my code...

jQuery(function() {
            var table = jQuery('#example').dataTable({
                "processing": true,
                "serverSide": true,
                                    "ajax": {
                    "url": "serverside",
                    "dataSrc": "jsondata"
                },
                "fnServerData": function ( sSource, aoData, fnCallback, oSettings ) {

                      oSettings.jqXHR = $.ajax( {
                        "dataType": 'json',
                        //"type": "POST",
                        "url": "serverside",
                        "data": aoData,
                        //"success": fnCallback
                      } );
                },
                                    "aoColumnDefs": [{ 
                        mData: "Id",
                        sType: "integer",
                        aTargets: [0] 
                    }, {
                        mData: "SerialId",
                        sType: "integer",
                        aTargets: [1]
                    }, {
                        mData: "critical",
                        sType: "string",
                        aTargets: [2], 
                    }
                                         ],
                                        });

Ok I solved the problem by using jQuery.ajaxSend(), I could not figure out datatable option...althougth I think preXhr event was close to helping me out..anyway here it is

    $( document ).ajaxSend(function( event, jqXHR, ajaxOptions ) {                  
                var table = $('#example').dataTable();
                var api = table.api();
                var order = api.order();
                //console.log("order details" + order[0][0]);
                var objCols = table.fnSettings().aoColumns;
                //console.log('Column name for order[0][0]' + objCols[0].mData);
                var applicationUrl = "url.php";
            //  ajaxOptions.url = ajaxOptions.url+"&orderby="+objCols[order[0][0]].mData+"&orderdir="+order[0][1];
                ajaxOptions.url = mdnsUrl+"?orderby="+objCols[order[0][0]].mData+"&orderdir="+order[0][1];                   
            //  console.log("URL"+ajaxOptions.url);
            });

Don't use ajax in combination with fnServerData - the two are mutually exclusive. Use only ajax to provide your own Ajax call, or better yet, if you just want to add extra data, simply use ajax.data.
