CSS

 .slider {
  height: 440px;
  overflow: hidden;
  position: relative;
 }
 .slider .btn li{
  position: absolute;
  width: 30px;
  height: 50px;
  cursor: pointer;
  color: #fff;
  text-align: center;
  font-size: 40px;
  top:45%;
 }
 .slider .btn li:first-child {
 
  left:0;
 
 }
 
 .slider .btn li:last-child {
 
  right:0;
 
 }
 
 .slider img {
  width: 100%;
  height: 100%;
 }
 
 .slider .window {
  width: 40000px;
  height: 400px;
  overflow: hidden;
 }
 
 .slider .window li {
  float: left;
  overflow: hidden;
  width: 1200px;
 }
 
 .slider .tab {
  position: absolute;
  z-index: 5;
  width: 880px;
  margin: -40px auto;
  left: 13%;
 }
 
 .slider .tab li {
  float: left;
  width: 200px;
  height: 80px;
  margin-left: 18px;
  cursor: pointer;
 }

Css文件可以根據需求自己DIY, 但html的.slider里面的結構應該是一樣。

Run 起來：
$('.slider').slider({auto: true, interval: 2000});

改進js結構：

/**
 * Created by Steven on 2015/07/10/0010.
 * @email zhuttymore@126.com
 */

(function ($) {

 $.fn.extend({
  slider:function (opt) {
   opt = $.extend({
    
   }, opt);
   //Do something here
   
   return $.each(this,function(index,ele){});
  }
 });

})(jQuery);
