jQuery DataTables fnrender with objects

I'm using jQuery DataTable to form a table out of this "data.txt":

{ "aaData" : [  
{       
    "ftitle": "Test1",
    "link": "http://server.com/test1/",
    "fname": "test1.pdf",
    "fid": "test1_353752165.pdf"
},
{       
    "ftitle": "Test2",
    "link": "http://server.com/test2/",
    "fname": "test2.pdf",
    "fid": "test2_353754257.pdf"
} ] }

This is my js code:

$('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "data/data.txt",
    "aoColumns": [
        {   "sClass": "center",
            "fnRender": function( oObj ) {
                return oObj.aData[0]+' '+ oObj.aData[2]; 
            } 
        },
        { "mDataProp": "fid", "sClass": "center" },
        { "mDataProp": "fname", "sClass": "center" }
    ],
} );

I just want to get the actual data with .aData of fnrender() but this works only with array-only data. What I get now is "undefined undefined", if I use a .txt with just array data it works fine.

I think I dont get it right how to use fnrender proberly, especially when working with objects.

You're getting "undefined" because oObj.aData is an object, not an array, and there is no "0" field. Use syntax like this:

oObj.aData.link

or

oObj.aData["link"]

Full example (only modified fnRender return value):

$('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "data/data.txt",
    "aoColumns": [
        {   "sClass": "center",
            "fnRender": function( oObj ) {
                return '<a href="' + oObj.aData.link + '">' + oObj.aData.ftitle + '</a>';
            } 
        },
        { "mDataProp": "fid", "sClass": "center" },
        { "mDataProp": "fname", "sClass": "center" }
    ],
} );
