How does jQuery .live() work?

Question

I was thinking about performance regarding

.click() vs .live(\"click\")

and that left me wondering about how .live does work.

Answer 1

From the jQuery manual on .live():

The .live() method is able to affect elements that have not yet been added to the DOM through the use of event delegation: a handler bound to an ancestor element is responsible for events that are triggered on its descendants. The handler passed to .live() is never bound to an element; instead, .live() binds a special handler to the root of the DOM tree.

As you see, there is no timer involved.
