// register callback
d.addCallback(function(name) {
log.debug("name: " + name)
});
// supply data
d.callback("Sam Jones");

or with errors:

JAVASCRIPT:

var d = new dojo.Deferred();
d.addCallback(function(v) { log.debug("success! : " + v) })
d.addErrback(function(e) { log.debug("error! : " + v) })
if (Math.random()> 0.5) {
d.callback("yea!")
}
else {
d.errback("boo!")
}

To give credit where it’s due, Dojo’s Deferred API is a direct port from MochiKit’s excellent implementation. All credit for this goes to Bob, and errors in the implementation are quite certainly ours.

I’m not the smartest JS-kid in town, but shouldn’t that read:
d.addErrback(function(e) { log.debug(“error! : ” + e) })?
