问题 We have an older ASP.NET WebForms application which performs AJAX request by using jQuery $.ajax() calls on the client side, calling static methods in the page code-behind decorated with [WebMethod] attributes. If an unhandled exception occurs within the WebMethod, it does not fire the Application_Error event and is thus not picked up by our error logger (ELMAH). This is well known and not a problem - we have all WebMethod code wrapped in try-catch blocks with exceptions being manually logged

问题 I've been working on a project for school and I within that project I want to call a server method (C# method) via the client side. I found out that using jQuery is one of the better methods to do this (because of ajax). And I got it working but after a week or more it suddenly stopped working. I don't think I changed much to the method, except the name. But I can't seem to figure out the problem. (I used debugging to check whether the method gets called or not and it doesn't seem to be
