如何设置无限循环幻灯片上的tumblr标题

Question

我希望我的幻灯片标题(在Tumblr主题上)无限循环，而无需单击下一个箭头请帮助。下列代码

var interval = undefined;
$(document).ready(function() {
  interval = setInterval(getNext, 3000);
  $("a#next").on('click', getNext);
  $("a#prev").on('click', getPrev);
});
function getNext() {
  var $curr = $("#slides .slides:visible"),
      $next = ($curr.next().length) ? $curr.next() : $("#slides .slides").first();
  transition($curr, $next);
}
function getPrev() {
  var $curr = $("#slides .slides:visible"),
      $next = ($curr.prev().length) ? $curr.prev() : $("#slides .slides").last();
  transition($curr, $next);
}
function transition($curr, $next) {
  clearInterval(interval);
  $next.css("z-index", 8).fadeIn("medium", function() {
    $curr.fadeOut().css("z-index", 0);
    $next.css("z-index", 7);
  });
}

直接删除

clearInterval(interval);

中的transition()函数。
