下一张和上一张幻灯片按钮功能 i++, i--

Question

上次问问题的经历很棒，我想我会回来寻求更多帮助。你们太棒了。先感谢您。

我正在使用一个特色帖子滑块，可以自动前进 4 个帖子。我想添加下一个和上一个按钮。我知道我需要将某种 .click() 事件附加到 #movers-next 和 #movers-previous，但到目前为止我尝试过的所有操作都导致性能参差不齐。

您能帮我编写一个循环变量“curclicked”的稳定方法吗？ （注意：.stripNav ul li a 是由插件自动生成的，作为循环帖子的一种方式）

谢谢。

<script type="text/javascript">
var theInt = null;
var $crosslink, $navthumb;
var curclicked = 0;

theInterval = function(cur){
 clearInterval(theInt);

 if( typeof cur != 'undefined' )
  curclicked = cur;

 $crosslink.removeClass("active-thumb");
 $navthumb.eq(curclicked).parent().addClass("active-thumb");
  jQuery(".stripNav ul li a").eq(curclicked).trigger('click');

 theInt = setInterval(function(){
  $crosslink.removeClass("active-thumb");
  $navthumb.eq(curclicked).parent().addClass("active-thumb");
  jQuery(".stripNav ul li a").eq(curclicked).trigger('click');
  curclicked++;
  if( 6 == curclicked )
   curclicked = 0;

 }, 8000);
};



jQuery(function(){

 jQuery("#main-photo-slider").codaSlider();

 $navthumb = jQuery(".nav-thumb");
 $crosslink = jQuery(".cross-link");

 $navthumb
 .click(function() {
  var $this = jQuery(this);
  theInterval($this.parent().attr('href').slice(1) - 1);
  return false;
 });

 theInterval();
});
