jQuery: trigger keypress function on entire document but not inside inputs and textareas?

Question

I have this …

$(document).keypress(function(e) {
        if ( e.keyCode === 119 ) // w
            doSomething();
    });

Wo when pressing \"w\

Answer 1

The easiest and perfect solution is:

$(document).keypress(function(e) {
    if (e.which == 119 && !$(':focus').length) {
        doSomething();
    }
});
