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 suppose I should pose that issue on a Zepto forum, but I thought someone might have a workaround here. awnings near me Toms River NJ

Zepto only makes use of the DOM-based event system so there's no way to get a real empty element to work as the global pub/sub-object. We might as well use ("").
