Is it possible for the 'error' attribute to be deemed invalid or inappropriate within ajax?

I am encountering an issue with my mobile cordova application. When attempting to log in, I am facing the following error:

Error: JavaScript runtime error - Object doesn't support property or method 'error'

The error is being traced back to this specific block of code:

 $.ajax({
           url: url,
           type: 'POST',
           data: { domainName: domain, username: username, password: password, appId: appId }

       })

           .done(function (json) {

               if (json.success) {
                   that.set("isLoggedIn", true);
                   token = json.token;
                   username = username;
                   isAuthenticated = true;
                   $('#show-Loader').hide();
                  window.location("#esig");

               }
               else {
                   navigator.notification.alert("No User Found", function () { }, "Login failed", 'OK');
                   //alert(json.error);
                   $('#show-Loader').hide();
                   return;
               }

           })
           //The issue arises when calling the 'error' method on $.ajax() 
      .error(function (xhr, status, error) {
          navigator.notification.alert('Unable to Connect to Server' + '\n' + ' Please check Settings.', function () { }, "Connection Failed", 'OK');
          $('#show-Loader').hide();
      });
   },

I am wondering if anyone has insights as to why this particular JavaScript error is occurring. My intention is to prompt an error message indicating a connection failure while testing the functionality.

Answer №1

Try using .fail() instead of .error(). (Note: .error() is not a valid function)

You have two options:

$.ajax({
    success: function() { ... },
    error: function() { ... }
});

or 

$.ajax({ ... })
.done(function() { ... })
.fail(function() { ... })
.always(function() { ... });  //<-- optional

The second approach is highly recommended.
