Returning single ID in JSON from a web service

I'm fairly new to working with client-side coding and was wondering what the the best way of returning a single ID from a simple Insert in a web service would be.

Copying code that returns more complex JSON objects, I'm doing the following: 

        Dim JaggedArray As String()() = New String(0)() {}
        Dim i As Integer = 0

        JaggedArray(i) = New String() {<insert stmt, returns integer>}

        Dim js As New JavaScriptSerializer()
        Dim strJSON As String = js.Serialize(JaggedArray)
        Return strJSON

I then use the following to access the ID in Javascript (excerpt from the AJAX call):

success: function(data) {
var c = eval(data.d);
var testID = c[0][0];

Surely there's a less clunky way of doing this, right?

And this is a stupid question, but can (and / or should) you put code outside of the Success callback, or is this mandatory?

Surely you can use jqXHR.done An alternative construct to the success callback option, the .done(),

for more info visit http://api.jquery.com/jQuery.ajax/

  $.ajax({
    //ajax stuff ..
  })
  .done(function(return){
    var output = "hello";
    return output;
  });
