    copied!<p>Im ready to start pulling my hair out here. Trying to use jquery ajax request in Firefox to return simple string from method in my code behind. Regardless of what I try, I always get parsererror - unexpected character. I tried at least a dozen different variations based on demos Ive found online, none work.</p> <pre><code> $.ajax({ type: 'POST', url: '/Search/BasicSearch.aspx/sayHello', contentType: "application/json; charset=utf-8", dataType: "json", data: '{}', success: function (msg) { alert(msg.d); }, error: function (jqXHR, textStatus, errorThrown) { alert(textStatus + ' ' + errorThrown); } }); </code></pre> <p>--code behind method</p> <pre><code>[WebMethod] public static string sayHello() { return "hello world"; } </code></pre> <p>I have tried returning a properly formatted json string in this method, still didnt work.</p> <p>EDIT: I forgot to mention that this site will is running on .NET 2.0. After unsuccessfully trying Will's suggestion below to set the response format to JSON, I thought I would try a plain 'ol generic handler and see what happens. Sure enough, it worked.</p> <p>public class Handler1 : IHttpHandler {</p> <pre><code>public void ProcessRequest(HttpContext context) { context.Response.ContentType = "application/json"; context.Response.Write("{\"\": \"hello world\"}"); } public bool IsReusable { get { return false; } } </code></pre> <p>}</p> <p>So I am assuming its an underlying issue with .NET 2.0 aspx pages??? I think all of the examples I have seen were using at least 3.0. </p>
