server return 500 error up vote 3 down vote favorite Ok, so I created a test project just to verify that jQuery AJAX works with asp.net service, and it does no problems. I used a default HelloWorld service created in VS studio.

/// Summary description for TestService /// [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

I have file Controll.aspx where is included javascript code. Next I have /Services/ControllService.asmx, where is the function, which I want call from js. js code: $(document).ready(function () { $('#btn_start').on('click', function () { $.ajax({ type: "POST", url: "Services/ControllService.asmx/Start", data: {}, dataType: "json", async: true, contentType: "application/json; charset=utf-8", success: function (response) { console.log(response); }, error: function (err) { alert("Error:" + err.toString()); } }); }); }); But I still getting the error 500.

Or you can analyse the response body from the network inspector where you will see the error page that is generated.. –Laurent Lequenne Apr 13 '15 at 21:15 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted SOLVED: 1 - I have defined Start function in ControllService.asmx.cs as static. 2 - I have badly configured data. It has to be named by the same way e.g. "sth". In javascript it should be: ... url: "Services/ControllService.asmx/Start", data: JSON.stringify({ sth: "hahaha" }), dataType: "json", ... and in ControllService.asmx.cs -> method Start public string Start(string sth){} Many, many thanks for your hints. share|improve this answer answered Apr 13 '15 at 21:47 DzeryCZ 12119 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Nam
