Prevent keyup event from firing when input box selected

I have an event that I want to fire whenever R or SPACE is pressed, with the exception of when in an input field.

Specifically, I'm worried about <input id='nameInput' type='text'> that I dynamically create when I click in a div and remove onchange/onblur. That's why I tried checking if( !$('#nameInput') ), but $('#nameInput') is a jQuery object, so its boolean value is always true (and hence !$('#nameInput') == false).

$(window).bind('keyup',
  function(e) { 
    var code = (e.keyCode ? e.keyCode : e.which);
    if(code == 32 || code == 82){
      if( !$('#nameInput') ){
        roll();
      }
    }
  }
);

I have a solution that utilizes a global boolean variable getting set in onfocus of the input field, but I'd like a solution that doesn't require a global variable if it's possible.

Is there a way to determine what element currently has focus?

You can use document.activeElement to know wich element currently has focus.

if (!$(document.activeElement).is('input, textarea')) {
    roll();
}

You could also make use of the :focus selector.

if (!$(':focus').is('input, textarea')) { 
    roll();
}
