jQuery event handling - bind to document or 'body' element?

Question

I have noticed the use of $(document) and $(\'body\') when we want to reference the entire page, especially when binding events.

$(         


        

Answer 1

Body is a child of document. Because of this, events will first reach the body before they are bubbled up to the document.
