Answer
Use error callback or fail() in promise style.
Quick Answer
Handle AJAX errors in jQuery: in the .ajax() options, use error: function(xhr, status, error) {} for the error callback. With Promises: $.ajax(opts).fail(function(xhr, status, error) {}). Set timeout: in ajax options, timeout: 5000 (ms) - if exceeded, triggers the error callback with status "timeout". Always handle both network errors and HTTP error status codes.
