Question

I have a small requirement that is to print the Keycode when any key is pressed.
Below is my code.. But it doesn’t seems to work, Please someone help me

$('document').keyup(function() 
{
alert(event.keyCode);
});

Answer 1

If you are looking for a small utility to grab the key codes, you could do this… which has the advantage of not having to click the ok on the alert.

html

<input />
<div></div>

script

$('input').keyup(function(){
    var kc = event.keyCode;
    $('div').html(kc);
});
