preventDefault() on keyup event not working

Question

I cannot get preventDefault() to work.

Here are some different code variations I have tried:

First:

$(document).keyup(function (evt)         


        

Answer 1

There is no default behaviour for .keyup(); it fires after the key press which triggers the default behaviour. Use .keydown() or.keypress()` instead.
