I am trying to populate a dataTable as follows:

$("#my-datatable").dataTable( {
    "sAjaxSource" : "/someURLOnMyServer",
    "bDestroy" : true,
    "fnServerParams" : function(serverParams) {
        serverParams.push(
            {
                "name" : "widget",
                "value" : token
            }
        );
    }
});

And the HTML table it is populating:

<table id="my-datatable">
    <thead>
        <tr>
            <th>Type</th>
            <th>Value</th>
            <th>ID</th>
            <th>Fizz</th>
            <th>Buzz</th>
        </tr>
    </thead>
    <tbody></tbody>
</table>

According to Firebug, the JSON ing back from the server is:

[
   {
      "id":1,
      "attributeType":{
         "id":1,
         "name":"test1",
         "tag":"test-type",
         "is-dog":false
      },
      "attributeValue":{
         "id":null,
         "name":"blah",
         "tag":"BLAH"
      },
      "buzz":1,
      "fizz":"53abc"
   }
]

But Firebug is throwing the following JavaScript error in its console:

TypeError: aData is undefined
[Break On This Error]   

for ( i=0 ; i<aData.length ; i++ ) --> jquery.dataTables.js (line 2541)

Can anyone spot what's going wrong? Either I'm not setting up my dataTable object correctly, or the JSON ing back doesn't match the "schema" of the HTML table it is trying to populate. Either way, I'm lost. Thanks in advance!

• javascript
• jquery
• json
• datatables

• Don't know much about jQuery dataTables, but I'd have to wonder if the fact that the JSON that is being returned is as an array might be the issue. – Kevin Boucher Commented Oct 11, 2012 at 20:08

Datatables requires a certain format for results. If you are not using that format, you have to declare everything.

$('#my-datatable').dataTable( {

    "sAjaxSource": "/url/here",


    "fnServerData": function ( sSource, aoData, fnCallback ) {
            aoData.push( { "name": "widget", "value": "token" } );

            request = $.ajax({
              "dataType": 'json', 
              "type": "GET", 
              "url": sSource, 
              "data": aoData, 
              "success": fnCallback
            });
      },


      "aoColumns": [
            { "mDataProp": "id"},
            { "mDataProp": "fizz"},
            { "mDataProp": "name"},
            { "mDataProp": "tag"},
            { "mDataProp": "tag"},
            { "mDataProp": "attributeValue.name"},
            { "mDataProp": "attributeValue.tag"},
        ],

    });

This is the format: http://datatables/release-datatables/examples/server_side/post.html

Try to enclose your JSON object with aaData like:

{"aaData" : 

[{"id":1,"attributeType":{"id":1,"name":"test1","tag":"test-type","is-dog":false},"attributeValue":{"id":null,"name":"blah","tag":"BLAH"},"buzz":1,"fizz":"53abc"}]

}
