Greetings,

No matter what I do I cannot get my jquery ajax code to get a response other than null from an ashx handler page.

Here is my hmt page:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>:: ashx tester ::</title>
    <link rel="stylesheet" href="js/jqueryui/1.8.6/themes/sunny/jquery-ui.css"
        type="text/css" media="all" />
    <script type="text/javascript" src="js/jquery/1.4.3/jquery.min.js"></script>
    <script type="text/javascript" src="js/jqueryui/1.8.6/jquery-ui.min.js"></script>
    <script type="text/javascript" src="js/json2/0.0.0/json2.js"></script>
    <script type="text/javascript">
        $(function () {
            $('#btnSubmit').click(
                function () {
                    DoIt();
                }
            );
        });

        function DoIt() {
            $('#btnSubmit').hide();
            $.ajax({
                type: "POST",                
                url: "http://localhost:49424/Handler1.ashx",
                data: {
                    firstName: 'Bob',
                    lastName: 'Mahoney'
                },
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function (response) {
                    alert('success: ' + response);
                    $('#btnSubmit').show();
                },
                error: function (response) {
                    alert('error: ' + response);
                    $('#btnSubmit').show();
                }
            });
        }
    </script>
</head>
<body>
    <input id="btnSubmit" type="button" value="Submit" />
</body>
</html>

And here is my ashx page:

Imports System.Web
Imports System.Web.Services
Imports System.Collections.Generic
Imports System.Linq
Imports System.Data
Imports System.Configuration.ConfigurationManager
Imports System.Web.Services.Protocols
Imports System.Web.Script.Serialization

Public Class Handler1
    Implements System.Web.IHttpHandler

    Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
        Dim j As New System.Web.Script.Serialization.JavaScriptSerializer
        Dim s As String

        s = j.Serialize(Now)
        context.Response.ContentType = "application/json"
        context.Response.Write(s)

    End Sub

    ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
        Get
            Return False
        End Get
    End Property

End Class

Any clues?

Thanks!

Dave

Try url: "/Handler1.ashx",

instead of

 url: "http://localhost:49424/Handler1.ashx",
