In Javascript event handling, why "return false" or "event.preventDefault()" and "stopping the event
- by Jian Lin
It is said that when we handle a "click event", returning false or calling event.preventDefault() makes a difference, in which
the difference is that preventDefault
will only prevent the default event
action to occur, i.e. a page redirect
on a link click, a form submission,
etc. and return false will also stop
the event flow.
Does that mean, if the click event is registered several times for several actions, using
$('#clickme').click(function() { … })
returning false will stop the other handlers from running?
I am on a Mac now and so can only use Firefox and Chrome but not IE, which has a different event model, and tested it on FF and Chrome and all 3 handlers ran without any stopping…. so what is the real difference, or, is there a situation where "stopping the event flow" is not desirable?
