Adding a condition for success or error using jQuery ajax + Wordpress

When using the Wordpress "nonce" system to authenticate an AJAX request, a response of "-1" is returned if the authentication fails. Rather than doing something like this in every jQuery.ajax success function:

success: function(msg){
    if (msg == '-1')
        console.debug('error')
    else {
        // ...
    }
}

is it possible to somehow augment jQuery and add a condition for my application that error: rather than success: is fired when the message returned is "-1"? Obviously much cleaner than a bunch of the same if statements.

I realize the normal response is to have the controller return a 4xx header, but would rather not have the Wordpress plugin change the default behaviour of the ajax handler and possibly mess up other Wordpress plugins.

Thanks!

There is also an error callback

http://api.jquery.com/jQuery.ajax/

Example

$.ajax({
  url: 'http://somewhere.com/index.html'
  success: function(data, textStatus, jqXHR) {
    //do stuff
  },
  error: function(jqXHR, textStatus, errorThrown) {
    //do stuff
  }
});
