Jquery ajax success call but web method breakpoint not hit

Question

I have a simple set up.

Jquery:

$.ajax({
  url: "/MyApp/MyHandler.ashx/MyMethod",
  success: function(result) {
    alert("sucess");
  },
  error: function() {
    alert('Error');
  }
});

and web method:

[System.Web.Services.WebMethod]
public static void MyMethod(){
  new AnotherClass(null).AnotherMethod(null, null); 
}

problem is success alert is called but break point is not hit inside MyMethod.

Try to disable `JQuery` `AJAX` caching `$.ajaxSetup({ cache: false });` — Michael, Feb 01 '16 at 07:01
@Anonymous Sorry, I've mistaken. You should use `[ScriptMethod(UseHttpGet = true)]` instead `[HttpGet]`. `[HttpGet]` is from MVC. [Here](http://stackoverflow.com/questions/941484/webmethod-vs-scriptmethod) are good answers why. — Kovalenko Ivan, Feb 01 '16 at 07:12

I had the same issue and this is what I ended up having to do:

$.ajax({
   url: _url,
   data: '',
   dataType: 'json',
   contentType: 'application/json',
   type: 'POST',
   success: function(result) {
      alert("sucess");
   },
   error: function() {
      alert('Error');
   }
});

My first attempt left out the data, dataType and contentType; Only when I set contentType: 'application/json' with an empty string (data: '') did it end up working. What a headache - hope this helps someone else!

In my case, the issue was in RoutingConfig.So, sort that in App_Start folder, within RouteConfig,commented out the following line

//settings.AutoRedirectMode = RedirectMode.Permanent;
