Good catch – fixed! As you can see in the jsfiddle, that line closed the jQuery onReady callback, which wasn’t included in this snippet.

with when if one request fails then they all fail. how can you wait for everything to execute even failures?

Excellent writeup. Thanks a lot. Your explanation clarified this in a way that the docs couldn’t. Thanks again!

I think you would have to do something like:

$.when.apply(this, deferredCollection).done… (etc)

hi there,

Just a question on this:

I’m trying to send a collection (array) of deferred objects to .when like this:

var deferredCollection = [];
deferredCollection.push(getTweets(‘austintexasgov’));
deferredCollection.push(getTweets(‘greenling_com’));
deferredCollection.push(getTweets(‘themomandpops’));
deferredCollection.push(getTweets(‘anotherUserA’));
deferredCollection.push(getTweets(‘anotherUserB’));

$.when( deferredCollection).done(function(atxArgs, greenlingArgs, momandpopsArgs, anotherUserAArgs, anotherUserBArgs){
// there is an error here trying to access atxArgs etc
});

is it possible to do something like this??

Thanks in advance.

Thanks very much for this.. I have been looking for this for a long time. Your example makes it very easy to understand the complicated deferred object articles on the net. Good work.

very useful. i didnt realize the arguments passed into the done function provided access to the success callback args. question; how do you get access to the complete, error, or other ajax callback arguments?

I thought it was When, Then, and Done
