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

Listening to keyup event is too late for calling preventDefault, try listening to keypress or keydown instead.

$('input[type=text], textarea').on('keydown', function(event){
    if (event.which == 192) {
        console.log('192');
        event.preventDefault();
    }
});

Note that jQuery normalizes which property and it's cross-browser.
