How do I catch jQuery $.getJSON (or $.ajax with datatype set to 'jsonp') error when using JSONP?

Question

Is it possible to catch an error when using JSONP with jQuery? I've tried both the $.getJSON and $.ajax methods but neither will catch the 404 error I'm testing. Here is what I've tried (keep in mind that these all work successfully, but I want to handle the case when it fails):

jQuery.ajax({     type: "GET",     url: handlerURL,     dataType: "jsonp",     success: function(results){         alert("Success!");     },     error: function(XMLHttpRequest, textStatus, errorThrown){         alert("Error");     } }); 

And also:

jQuery.getJSON(handlerURL + "&callback=?",      function(jsonResult){         alert("Success!");     }); 

I've also tried adding the $.ajaxError but that didn't work either:

jQuery(document).ajaxError(function(event, request, settings){    alert("Error"); }); 

Thanks in advance for any replies!

Here's my extensive answer to a similar question.

Here's the code:

jQuery.getJSON(handlerURL + "&callback=?",      function(jsonResult){         alert("Success!");     }) .done(function() { alert('getJSON request succeeded!'); }) .fail(function(jqXHR, textStatus, errorThrown) { alert('getJSON request failed! ' + textStatus); }) .always(function() { alert('getJSON request ended!'); });
