jquery - javascript prevent default for keyup

Question

I have the following code:

$(document).on('keyup', 'p[contenteditable="true"]', function(e) {
    if(e.which == 13) {
        e.preventDefault();
        $(this).after('<p contenteditable = "true"></p>');
        $(this).next('p').focus();
    } else if((e.which == 8 || e.which == 46) && $(this).text() == "") {
        e.preventDefault();
        alert("Should remove element.");
        $(this).remove();
        $(this).previous('p').focus();
    };
});

I would like to prevent the default action when a key is pressed. preventDefault works for keypress but not keyup. Is there a way to prevent the defualt for $(document).on('keyup')?

No. keyup fires after the default action.

keydown and keypress are where you can prevent the default.
If those aren't stopped, then the default happens and keyup is fired.
