I'm trying to set up a simple JQuery example in order to make AJAX calls to a .NET webservice. Using the following example below I'm getting AJAX errors that are just saying 0 in the result instead of any meaningful message:
Javascript Call
function QSHelloWorld() {
var options = {
type: "POST",
url: "http://localhost:1087/QueryService.asmx/HelloWorld",
data: "{}",
contentType: "application/json",
dataType: "json",
success: AjaxSucceeded,
error: AjaxFailed
};
$.ajax(options);
}
function AjaxSucceeded(result) {
alert(result.d);
}
function AjaxFailed(result) {
alert("Error: " + result.status + " " + result.statusText);
}
ASP .NET WebSite
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="jQueryTest._Default" %>

<form id="formMain" runat="server">
<div>
<script type="text/javascript">
QSHelloWorld();
</script>
</div>
</form>
</body>
</html>
ASP .NET WebService
using System.Web.Script.Services;
using System.Web.Services;
namespace QueryService
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class QueryService : WebService
{
[WebMethod]
[ScriptMethod]
public string HelloWorld()
{
return "Hello World";
}
}
}
When I make a call to the QSHelloWorld I get a messagebox saying Error: 0 with no further information.
I'm currently running this example using Windows 7, do I need to have anything specifically installed besides the .NET Framework 3.5 SP1 in order to get this to run properly?
Thanks,
Daven
