    copied!<p>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:</p> <p>Javascript Call</p> <pre><code>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); } </code></pre> <p>ASP .NET WebSite</p> <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="jQueryTest._Default" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;script language="javascript" type="text/javascript" src="js/jquery-1.3.2-vsdoc2.js" /&gt; &lt;script language="javascript" type="text/javascript" src="js/qsAJAX.js" /&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" &gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="formMain" runat="server"&gt; &lt;div&gt; &lt;script type="text/javascript"&gt; QSHelloWorld(); &lt;/script&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>ASP .NET WebService</p> <pre><code>using System.Web.Script.Services; using System.Web.Services; namespace QueryService { /// &lt;summary&gt; /// Summary description for Service1 /// &lt;/summary&gt; [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class QueryService : WebService { [WebMethod] [ScriptMethod] public string HelloWorld() { return "Hello World"; } } } </code></pre> <p>When I make a call to the QSHelloWorld I get a messagebox saying Error: 0 with no further information.</p> <p>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?</p> <p>Thanks,</p> <p>Daven</p>
