Question

Answer 1

event.preventDefault() and return false; are one thing - they instruct the browser not to process the default action for the event (in this case, navigating to the href of the anchor tag that was clicked). href=javascript: and its ilk are something else - they're causing the default action to be 'do nothing'.

It's a question of style. Do you want to do all your work in the onclick, or do you want to be able to put actions in both the onclick and the href and rely on the capabilities of the browser to modulate between the two?
