Question

I want to have all ajax requests check the HTTP response code, is it possible to create a function and have this run for all my ajax requests by default? Thx!

Answer 1

You can supply defaults for any of the jQuery.ajax options by calling jQuery.ajaxSetup. Based on your other questions you probably want something like this:

$.ajaxSetup({
    complete: function(jqXHR, textStatus) {
        // Do your checking and logging.
    }
});

Or even:

$.ajaxSetup({
    complete: checkResponseCode
});

But keep in mind that this is called after your success or error callbacks.
