I have a multivariable multiple class json coming as a result.

I have a multivariable multiple class json coming as a result.  From [WebMethod} I have this string returning (certain it is correct):

[{"id":"0","date":"3/4/2001","name":"John Doe","title":"IT"},{"id":"1","date":"3/4/2001","name":"Jane Doe","title":"Homemaker"}]

etc

I want TextBox4 to print the json string.

Right now it just prints out the Error Code:

Error Code: Status: [object Object] Ex: error

How can I correct that?

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script><script type="text/javascript">$(document).ready(function () {$("#<%= Button1.ClientID %>").click(function () {
                var mo1 = $("#<%= TextBox1.ClientID %>").val();
                var dy1 = $("#<%= TextBox2.ClientID %>").val();
                var yr1 = $("#<%= TextBox3.ClientID %>").val();
                var data = { mo:mo1, dy:dy1, yr:yr1 };
                var json1 = JSON.stringify(data);$.ajax
                ({
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    data: json1,
                    url: "Default.aspx/GetDateData",
                    success: function (result) {$("#<%= TextBox4.ClientID %>").val(result.d);
                    },
                    error: function (status, ex) {
                        alert("Error Code: Status: " + status + " Ex: " + ex);
                    }
                });
                return false;
            });
        });</script>
