jQuery.AJAX and the "always" callback

This effects some of the JavaScript work-around code we have in circulation, especially the GeoLocation code (from memory). I've found (and officially complained about: http://bugs.jquery.com/ticket/11548) the way AJAX works in jQuery.

If your code combines $.get / $.load / $.post / $.ajax with an ".always" function, then you'll probably need to compensate for this issue. Basically, the order of the ".always" parameters is different depending on if the AJAX request failed or succeeded, meaning the code we have in circulation only behaves as expected when the request is successful.

You probably have something like:

$.ajax('http://my.url/request.php')
.always(function(response, status, jqxhr) {
 // your code here
});

$.ajax('http://my.url/request.php')
.always(function(response, status, jqxhr) {
 var swap;
 if (!jqxhr || $.type(jqxhr.promise) !== 'function') {
   swap = jqxhr;
   jqxhr = response;
   response = swap;
 }
 // your code here
});
