jquery.all.js

// Extending jQuery.when
if (jQuery.when.all === undefined) {
    jQuery.when.all = function(deferreds) {
        var deferred = new jQuery.Deferred();
        
        $.when.apply(jQuery, deferreds).then(
            function() {
                deferred.resolve(Array.prototype.slice.call(arguments));
            },
            function() {
                deferred.fail(Array.prototype.slice.call(arguments));
            }
        );

        return deferred;
    }
}

What happens if one or more requests fail? Do you get a fail for those that failed and resolve callbacks when the successful ones complete? I guess I'm asking if you get the complete picture. I have a situation where I need to make multiple requests but I need to know if any fail and I also need to know when ALL requests have completed (either succeeded or failed). Thanks
