Wrap jQuery's $.ajax() method to define global error handling

Question

Branching off of questions like this one, I\'m looking to wrap jQuery\'s $.ajax() method such that I can provide error handling in one location, which would then be used aut

Answer 1

You might want to look at $.ajaxError.

$(document).ajaxError(function myErrorHandler(event, xhr, ajaxOptions, thrownError) {
  alert("There was an ajax error!");
});

jQuery provides a whole bunch of other ways to attach global handlers.

To answer your edit, you can catch successful ajax requests with $.ajaxSuccess, and you can catch all (successful and failed) with $.ajaxComplete. You can obtain the response code from the xhr parameter, like

$(document).ajaxComplete(function myErrorHandler(event, xhr, ajaxOptions, thrownError) {
  alert("Ajax request completed with response code " + xhr.status);
});
