              function fnGetSelected( oTableLocal ) {
                        var aReturn = new Array();
                        var aTrs = oTableLocal.fnGetNodes();
                        for ( var i=0 ; i<aTrs.length ; i++ )
                        {
                          if ( $(aTrs[i]).hasClass('row_selected') )
                          {
                           aReturn.push( aTrs[i] );
                           }
                        }
                        return aReturn;
                }

I don't know exactly how it is supposed to fit into your code, and your question needs more fleshing out, but I suppose you could select the row next to the clicked one like this:

$("#datalist > tr").click(function() {
    $(this).next("tr").addClass('row_selected');
});
