Prevent keydown() from being captured by document binding
Question by Elliot Bonneville
I’m not exactly sure how to phrase this, so I couldn’t search it. Basically, I have a keydown() bind on $(document). I’d like to show() another div, and have all keydown events be rerouted to this div and prevented from firing off in the document handler. Is this even possible, or would I have to put all my main keybindings on another div and work from there?

e.stopPropagation, or
e.preventDefault (depending on the situation)
Where e is the event.
Ex:
function onKeyDown(e) {
doStuff();
e.preventDefault();
}

e.preventDefault() will prevent the default behaviour of an event. What you need is to use
e.stopPropagation(), so that the event does not bubble up the DOM structure.
To read more about the difference, read this post.
$(element).keydown(function(e) {
// do the task
// allow the default behaviour also
e.stopPropagation();
//^. BUT stop the even bubbling up right here
});
e.stopProgation(), can be bit confusing to grasp on the first but I created a demo with click event to explain it.
Hope it helps!!
