How to write number of characters of a string in a textfield?

Okay, I have this textfield form that contains some text. What I need to do is to count number of characters of that particular string and print it into another textfield form, basically like this:

function numberOfCharacters() {

    var number = document.forms[0].textfield1.length;
    document.forms[0].textfield2.value = number;

}

When I do this, textfield2 contains "undefined" string. Thank you

Using jQuery:

$('#text-input').bind('keyup', function() {
   $('#char-count-ouptput').val($(this).val().length);
});
