what's the difference of return true or false here?

$('form').submit(function() {
  alert($(this).serialize());
  return false;  // return true;
});

what's the difference for this form submission function between return false and true?

As already mentioned, returning false stops the event from "bubbling up". If you want the full details, take a look at the API documentation for bind(): http://api.jquery.com/bind/.

"Returning false from a handler is equivalent to calling both .preventDefault() and .stopPropagation() on the event object."

return false, don't do the form's default action. return true, do the form's default action.

It's also better to do

$('form').submit(function(e) {
  alert($(this).serialize());
  e.preventDefault();
});

If you return false from the submit event, the normal page form POST will not occur.
