Quick and dirty list item rotation (eg: for carousels), a reminder to myself. Can't remember where I found this :(

gistfile1.js

var rotate = function() {
    $('.carousel ol').each(function(){
        var $cur = $(this).find('.current').removeClass('current');
        var $next = $cur.next().length?$cur.next():$(this).children().eq(0);
        $next.addClass('current').trigger('change');
    });
}
var interval = setInterval(rotate, 4000);
