从幻灯片中随机移动

Question

我在我的网站上播放了一个幻灯片，但出于某种原因，幻灯片的移动不应该是默认的，它会从第一张幻灯片跳到第三张幻灯片然后再回到第一张幻灯片。

然后，如果你使用手动导航（圆圈）并进入1,2,3,4，他做出了正确的动作但是他开始做出奇怪的动作，只是自己测试几次，你会看到我我在说什么。我的目标是制作第一张幻灯片，分别为2分，3分和4分，然后重置，简单。

var seconds = 2; //time beetwen auto slide
var delay = 8; //time to restart auto slide

var slider = $('#slider');
var images = $('#slider .images');
var controls = $('<div>').addClass('controls');
slider.after(controls);
var width = images.width();
var slideClick = function () {  
  var b = $(this);
  $('.controls div').removeClass('current');
  b.addClass('current');
  var index = b.index();
  images.css('left', -1 * index * width);
};
$('#slider .images img').each(function (i) {
  var img = $(this);
  img.css('left', i * width);
  var button = $('<div>');
  controls.append(button);
  if (i == 0) { button.addClass('current') }
  button.click(function(){
    clearInterval(autoSlideInterval);
    slideClick.apply(this);
    setTimeout(function () {
       setInterval(autoSlide, seconds * 1000);     
    }, delay * 1000);
  });
});
var autoSlide = function(){
  var next = $('.controls .current').next();

    slideClick.apply(first);
