So, I am trying to make one generic page for any table that is being requested by user. For that I am trying to fetch all data from server and not having anything hardcoded on the clientside.

```
 $(document).ready(function(){

     /* Add/remove class to a row when clicked on */
    $('#table1 tr').on('click', function() {
        $(this).toggleClass('row_selected');
    } );

     var which_table=window.location.pathname;
     var which_table_data=which_table.substring(0, which_table.length-1)+'/data';
     var table_name=which_table.substring(14, which_table.length-1);
     $('#table1').dataTable({
            "bProcessing": true,
            "bServerSide": true,
            "bjQueryUI": true,
            "sAjaxSource": which_table_data,
            "bPaginate": true,
            "sPaginationType": "full_numbers",
            "bjQueryUI": true,
            "sScrollX":"100%",
            "aoColumnDefs": [{
                "targets" : [0],
                "visible" : false,
                "searchable" : false
            }]
    }).makeEditable({
         "sUpdateURL": "../update/" + table_name,
         "sAddURL": "../add/" + table_name,
         "sDeleteURL": "../delete/" + table_name,
         "aoColumns": $.ajax({
                      dataType: "json",
                      url: '/get_aoColumns',
                      data: function (table_name) {
                          return {
                              q: table_name
                          };
                      },

                      results: function (data) {
                            alert(data);
                        }

                    });

    });

 });

```

So in this piece based on the `var which_table=window.location.pathname;` I try to get the data for the corresponding table from the server in which I am successful. But now I want to get even the aoColumns array from the server. My question is can I send the data in the same request along with the aoData, secho and other required fields. I think that may not render datatable properly since aoColumns in not a part of the required json. How do I get the aoColumns for any table so that even the validation becomes server side and I won`t have to design one page per table.

This below part doesnt work as I don`t know what is the correct way of doing it

```
"aoColumns": $.ajax({
                      dataType: "json",
                      url: '/get_aoColumns',

```

**EDITED** :-

I tried @garryp`s approach ..

This is the **data** I get from the server 

```
[{"cssclass": "required", "type": "textarea"}, {"sUpdateURL": "../update/my_table", "cssclass": "required", "type": "textarea", "loadtype": "POST", "submit": "OK"}, {"loadurl": "../data/", "sUpdateURL": "../update/my_table", "loadtype": "POST", "type": "select", "submit": "OK"}]

```

This is my **code** :

```
 $(document).ready(function(){

     /* Add/remove class to a row when clicked on */
    $('#table1 tr').on('click', function() {
        $(this).toggleClass('row_selected');
    } );

     var which_table=window.location.pathname;
     var which_table_data=which_table.substring(0, which_table.length-1)+'/data';
     var table_name=which_table.substring(14, which_table.length-1);
     if(table_name.indexOf('Welog')> -1) {
         $('#table1').dataTable({
             "bProcessing": true,
             "bServerSide": true,
             "bjQueryUI": true,
             "sAjaxSource": which_table_data,
             "bPaginate": true,
             "sPaginationType": "full_numbers",
             "bjQueryUI": true,
             "sScrollX": "100%"
             });
           $('#formAddNewRow').hide();

        }
     else {
         $.ajax({
             url: '../get_aodata/' + table_name,
             async: false,
             success: function (data) {
                 alert(data);
                 $('#table1').dataTable({
                     "bProcessing": true,
                     "bServerSide": true,
                     "bjQueryUI": true,
                     "sAjaxSource": which_table_data,
                     "bPaginate": true,
                     "sPaginationType": "full_numbers",
                     "bjQueryUI": true,
                     "sScrollX": "100%",
                     "aoColumnDefs": [{
                         "targets": [0],
                         "visible": false,
                         "searchable": false
                     }]
                 }).makeEditable({
                     "sUpdateURL": "../update/" + table_name,
                     "sAddURL": "../add/" + table_name,
                     "sDeleteURL": "../delete/" + table_name,
                     "sAddDeleteToolbarSelector": "#table1_length",
                     "aoColumns" : data

             /*"aoColumns" : [
                         {
                             "cssclass": "required",
                             "type":"textarea"
                         },
                         {
                             "cssclass": "required",
                             "type":"textarea",
                             "submit"  : "OK",
                             "sUpdateURL": "../update/"+table_name,
                             "loadtype" : "POST"
                         },
                         {
                             "loadurl" : "../data/",
                             "type" : "select",
                             "submit": "OK",
                             "sUpdateURL": "../update/"+table_name,
                             "loadtype" : "POST"
                         }
                     ]*/

                 });
             }
         });
     }

 });

```

So if you see the commented out aoColumns in this code is exactly the same as the output got from the server, but the one got from the server doesn`t work and the one commented out if uncommented does work. The one got from the server if used using aoColumns : data just behaves the same way as if aoColumns parameter wasn`t mentioned at all in the makeditable function. Does that mean data is not reaching that parameter coz I don`t get any errors in the console.

Solution :-

```
success : function(data){
  var data_str= JSON.parse(data);
});

```

Ok. I had to convert the json string to JSobject using parse and then it finally worked.
