Confused about fnServerData

Charley

I'm trying to implement server side processing using DWR.

With this itialization of my datatable:

        $(document).ready(function() {
            $('.ajaxDataTable').dataTable( {
                "processing": true,
                "serverSide": true,
                "ajaxSource": StyleGuideDAO.SearchDemo,
                "fnServerData": function ( sSource, aoData, fnCallback ) {
                    sSource( JSON.stringify(aoData),
                        function (json) { 
                        try{
                            fnCallback(JSON.parse(json))
                        } catch(err){alert("ERROR MESSAGE:" + err)}
                    } ); 
                }
            } );
        } );

And a dummied up SearchDemo DWR method, I can get results back. But it doesn't seem to be sending all of the expected parameters. In particular, int draw, start, and length are all missing.

Looking at the source code, it looks kind of like fnServerData is a holdover from 1.9. Is there a more correct way to override how the ajax call is done for 1.10?

Here are some examples that show SSP with Datatables 1.10:
https://datatables.net/examples/server_side/index.html

In the docs you will want to look at:
ajax
ajax.data
ajax.dataSrc

Also you will probably want to look at the Server Side Processing doc:
https://datatables.net/manual/server-side

Please post any questions.

it looks like this is how that would work in 1.10

$(document).ready(function() {
$('.ajaxDataTable').dataTable( {
"processing": true,
"serverSide": true,
"ajax": function (data, callback, settings) {
StyleGuideDAO.SearchDemo(JSON.stringify(data), function (json) {
//alert(json);
try{
callback(JSON.parse(json))
} catch(err){alert("ERROR MESSAGE:" + err)}
})

                }
            } );
        } );
