jquery: event.stopImmediatePropagation() vs return false

Question

Is there any difference between calling event.stopImmediatePropagation() and return false inside an event handler ?

Answer 1

Yes. event.stopImmediatePropagation() won't let any other handlers for that event be called, regardless of where they are bound. Return false only stops handlers bound to other elements (ie not the same element as the event handler dealing with the stopImmediatePropagation() call) from receiving the event.
