Question

Answer 1

you can use the global ajax event handlers .ajaxError()

$( document ).ajaxError(function( event, jqxhr, settings, exception ) {
    if ( jqxhr.status== 401 ) {
        $( "div.log" ).text( "Triggered ajaxError handler." );
    }
});

Answer 2

You can do something like this:

$(function() {
    $.ajaxSetup({
        error: function(jqXHR, exception) {
            if (jqXHR.status === 401) {
                alert('HTTP Error 401 Unauthorized.');
            } else {
                alert('Uncaught Error.\n' + jqXHR.responseText);
            }
        }
    });
});

This will catch error in any of your ajax calls.
