Performance difference between jQuery's .live('click', fn) and .click(fn)

Question

I love the new live event in jQuery 1.3. The question I have is the performance of this event. I know the advantages of using live over click/bind(\'click\') but is there

Answer 1

If not, why would you ever use click or bind('click')?

Because $.live() has some significant disadvantages

• Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation (This changed in jquery 1.4.4) or stopImmediatePropagation. For example, take the case of two click events - one bound to "li" and another "li a". Should a click occur on the inner anchor BOTH events will be triggered. This is because when a $("li").bind("click", fn); is bound you're actually saying "Whenever a click event occurs on an LI element - or inside an LI element - trigger this click event." To stop further processing for a live event, fn must return false.
• Live events currently only work when used against a selector. For example, this would work: $("li a").live(...) but this would not: $("a", someElement).live(...) and neither would this: $("a").parent().live(...).
