Retrieving error message in ASP.NET Ajax upon failure

Using MVC2, I am attempting to show a user-friendly error message. Here is my approach:

public ActionResult Foo()
{
  Response.StatusCode = 403;

  return new ContentResult() { Content="friendly error" }
}

However, I am struggling to figure out how to access it in the AJAX OnFailure callback:

function ajaxErrorHandler(context) {

// This triggers an error, stating that it's not a JSON object
    alert(context.get_response().get_object());

}

I can confirm through Firebug that the response is correct. Any suggestions?

Answer №1

Below is the provided code snippet:

alert(context.get_data());

The above code will show a "friendly error" message.

Answer №2

Here is a suggestion to consider: To access the message within the onFailure callback, you can use context.get_message()...

In your code snippet, make sure to include the following function for handling failures:

function OnFailure(context) {
            alert(context.get_message());
    }

I found this approach to be effective. -- Sudipto www.supernovaservices.com
