Re: [JSMentors] $('body') vs $(document) in Pub/Sub pattern
Hi Joel,
I didn't thought about the first point, thanks for that. About the
second one, I thought about it but found that I could get intro trouble
with certain versions of jQuery if I tried to unbind events since jQuery
seems to try to call "detachEvent" or "removeEventListener" (depending
on the browser) assuming always the object is a DOM element and that's
the reason I wanted to use $(document) or $('body')
I'm not really interested in bouncing events off the dom as you say, so
I'll probably go for something like this jquery plugin someone suggested
in the list: https://gist.github.com/661855
Thanks.

$(document).trigger works the same way as $(myNS).trigger where myNS is your
global namespaced object
This probably makes more sense to your app than bouncing events off the dom
anyway.

There is one small difference. The $(document) selector is a bit
faster. I dont think that there would be other difference.
right and then the question is: why would you even be running a dom
selector/instantiating a jq obj for something that has
little-to-nothing to do with the DOM. The point of pubsub is that it's
_not_ coupled to anything.

Re: [JSMentors] $('body') vs $(document) in Pub/Sub pattern
it would only really matter if you were triggering dom events. Also, the
point about it going the event system and bubbling and whatnot still is
valid.

Hi guys,
I know this is more jQuery related question and perhaps it'd be
better to ask in its forum but I'll drop it in case some jQuery
experts in this group could answer it. Is there any reason why I
should be using "$(document).bind/trigger" over
"$('body').bind/trigger" (or the other way around) if I wanted to
use it as a PubSub ? Any different in terms of performance or others ?
Thanks
Hello,
maybe it's worth checking out this jQuery plugin for your pub/sub
needs: https://gist.github.com/661855

Re: [JSMentors] $('body') vs $(document) in Pub/Sub pattern
That plugin is essentially the same thing as using $(body).trigger/bind,
has the overhead of going through the event system and is actually
larger by a few bytes* than my simplified version:

* or at least it was the last time ben and I compared them ...
