[jQuery] stopping form submission?

[jQuery] stopping form submission?


Coming from prototype, still new to jQuery..
Trying to stop a form submission like so:
<form name='register' id='form_register' action='/register'
method='post'>....</form>
Clicking on an input with type of submit. Then the javascript:
$('#form_register').submit(function () {
    alert('die');
    return false;
});
Yet this isn't stopping the event. In prototype, you could observe the
submit event, and call event.stop(). Anything similar in jQuery?
Thanks!
