server side processing and manipulating data returned

shavo30

I am using datatables version 1.10.0 for search capability.

I want to know for server side processing how do i manipulate the response. For example I have a json response that returns with the records to display and also a status.

My requirement is, if there is validation failure on the server side, I do not want to draw the table and instead, render error messages on screen. Otherwise if success draw the table.

Simple Example below:

$('#result').dataTable( {
        "processing": true,
        "serverSide": true,

        "ajax": {
            "url": "search",
            "type": "POST",
            //"dataSrc": "resultList",
            "dataSrc": function ( json ) {
        if (json.responseStatus.value == 'Validation Failure') {
    //show error messages on screen
//prevent redraw
         } else {

    //draw the table with the  resultList
    }
              }
        "columns": [
                    { "data": "referenceNumber"},
                    { "data": "fileName" },
                    { "data": "documentType" },
                    { "data": "uploadType" },
                    { "data": "createdBy" },
                    { "data": "memberName" },
                    { "data": "dateOfBirthStr"},
                    { "data": "createdDateStr" },
                    { "data": "comment" },
                    { "data": "status" }
                ]
    } ); 

Is this possible?

Thanks.

UPDATE:
On the server side I return 403:

return new ResponseEntity<SearchUploadResponse>(searchUploadResponse, HttpStatus.FORBIDDEN);

On the client side:

    $('#result').dataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "search",
            "type": "POST",
            "dataSrc": "resultList",
                     error: function (jqXHR, textStatus, errorThrown) {
                           //handle errorThrown in here
                         alert("error" + jqXHR  + " : " + textStatus + " : " + errorThrown);
                     }
        } ,

The result is i can show my error messages.
datatables blocks access to the table with the "processing" div.

Is this the correct approach?
