adding classes (serially numbered) to each DIV on page automatically via javascript?

I want to add a class which “numbers” all the <div>s, problem is, is that it overrides the existing classes.

$('div').attr('class', function(i) {
    return 'someClass' + i;
});

Answer 1

$('div').each(function(i){
    $(this).addClass('class' + i);
});

Or:

$('div').addClass(function(i){
    return "class" + i;
});
