jquery - Difference between .success() and .complete()?

Question

As of jQuery 1.5, all jQuery's AJAX methods return a jqXHR object that provides .error(), .success(), and .complete() methods.

What is the difference between .success() and .complete()?

Answer 1

.success() only gets called if your webserver responds with a 200 OK HTTP header - basically when everything is fine.

However, .complete() will always get called no matter if the ajax call was successful or not - maybe it outputted errors and returned an error - .complete() will still get called.

It's worth mentioning that .complete() will get called after .success() gets called - if it matters to you.
