Ajax. Where is the mistake?

Question

JavaScript

I can't figure out where the error is. I did this 100500 times and everything worked, and then suddenly it gives out

common.js:4 Uncaught SyntaxError: Unexpected token :

The code itself

var $form = $('#reg').serialize();
$.ajax(function() {
  url: 'app/helper/auth.help.php',
  method: 'POST',
  data: $form,
  success: function(data) {
    console.log(data);
  },
  error: function (xhr, status, error) {}
});

Answer 1

var $form = $('#reg').serialize();
$.ajax({
  url: 'app/helper/auth.help.php',
  method: 'POST',
  data: $form,
  succes: function(data) {
    console.log(data);
  },
  error: function (xhr, status, error) {}
});

Answer 2

succes: function(data) {

Правильно будет: success
