This is related to my question on how to handle errors from jQuery AJAX

  • 0

This is related to my question on how to handle errors from jQuery AJAX calls. Several responses suggested that I use the ‘error’ callback to display any errors from a jQuery AJAX call. I was wondering how to do that using ASP.NET MVC. Is there a way for my controller action to return an error that would be accessible from the ‘error’ callback? The client side code would look something like this:

$.ajax({    type: 'POST',    url: 'MyUrl',    data: 'val1=test',    success: function(result){         // Do stuff    },    error: function(request,status,errorThrown) {     }  });

  1. NOTE: Hey, this was posted before ASP.Net MVC even hit 1.0, and I haven’t even looked at the framework since then. You should probably stop upvoting this.

    Do something like this:

    Response.StatusCode = (int)HttpStatusCode.BadRequest; actionResult = this.Content('Error message here');

    The status code should change depending on the nature of the error; generally, 4xx for user-generated problems and 5xx for server-side problems.
