keydown on body?

Question

I want to get alerted whenever I press a key.

I\'ve tried:

$(\'body\').live(\'keyup\', function() {
     alert(\'testing\');
});

Try using $("html") or $("*") instead of $("body"). In order for the keyUp event on body to fire, the body node or one of its children must be focused. You can accomplish this in your example by adding a text input and focusing the mouse to that input. What you really want is to capture any key press, so $("html") should work.

Edit: I think your example might work, but in any case, to run the logic conditionally you might try this:

if ($(document.body).is(".focusOnKeypress")) {
   $("html").live(...);
}

Or, I think this will also work:

$("body:not(.noFocusOnKeypress)").parent("html").live(...);
