@connected - what's the default event you're trying to prevent? isn't this limited to the arbitrary hidden topic var o? just curious.

@kodi thanks for the requirejs module implementation!

How would you add support for wildcards in the topic name? Does it even make sense as jQuery doesn't support wildcards for event names? Or is using a standalone pub/sub library the better approach?

I know some javascript and little of jQuery (been playing with Ember, just for fun). I understand the on off methods, but I do not understand what var o = $({}); does. Can anyone please explain?

As always, google doesn't consider these braces and the $ in its search results.

@gmanish var o = $({}) simply creates a jQuery collection with an empty object {} that becomes the recipient of all the event triggers. As other comments show, the recipient could be anything like $('<b />').

I am telling you this is working really good.
