Question

I’m working with the jQuery Form Plugin. I have my servers send 200 responses on success, which trips the success listener perfectly fine. Per the standard, 301 and 302 and transparently redirected by the browser. However, when the server returns, say a 401, the Form Plugin just silently dies. How can I apply a listener to non-200 responses?

The XHR will have the responseStatus in it – you can use the complete handler instead of ‘success’ and check that property of the xhr.

$.ajax({ // ...
        complete: function(xhr){
           if( xhr.responseStatus == 401 ) {
               alert( 'awww crap' );
           }
         }
      });
