I have array like this... I am fetching the values in the array

in search.php page, if i dont have any values in this array
how can i show the Message "There is no value"; in autocomplete in
jquery..
Here is the Jquery code:
$("#patientsearchresults").autocomplete("/SSHD/patientsearch/
controller/PatientSearchController.php?action=patientSearch", {
        formatItem: function(row) {
    row = eval("(" + row + ")");
            return row['PatientLastName'] + ", "+ row['PatientFirstName'] + " "
+ row['DateOfBirth'];
},
        formatResult: function(row){
            row = eval("(" + row + ")");
            row = row['PatientLastName'] + ", "+ row['PatientFirstName'];
        }
    }).result(function(event, row) {
        row = eval("(" + row + ")");
         location.href = "/SSHD/patientchart/PatientChartHome.php?
PatientUUID=" + row.PatientUUID;
    });
PHP code :
foreach($arrSearchResults as $row) {
echo json_encode($row);
echo "\n";
