Stopping propagation of mousedown/mouseup from a click handler

Answer 1

Yes. Since mouseclick and mousedown/mouseup are different events, you can't get at one from the other at all - you have to do it from within your own mousedown/mouseup handlers. What you can do is refactor that into a generic method to use in both places:

stopPropagation('#inner', 'mousedown');
stopPropagation('#inner', 'mouseup');

function stopPropagation(id, event) {
    $(id).on(event, function(e) {
        e.stopPropagation();
        return false;
    });
}
