1.首先看一下目录结构

images文件夹放所需要播放的图片。

js文件夹放jquery库和main.js

2.html代码：

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="utf-8">
 5     <title>JQuery slideShow</title>
 6     <style>
 7     *{margin: 0;padding: 0}
 8     ul,ol{list-style: none;}
 9     .slideShow{position: relative;margin: 100px auto;height: 140px;width: 340px;overflow: hidden;}
10     .slideShow ul{ position: relative;width: 2000px; }
11     .slideShow ul li{float: left;width: 340px}
12     .slideShow .nav{text-align: center;position: absolute;right: 10px;bottom: 10px;font-size: 12px;line-height: 18px;}
13     .slideShow .nav span{ -webkit-user-select:none;user-select:none;float: left;cursor: pointer;border-radius: 9px;display: inline-block;width: 18px;height: 18px;background:rgba(0,0,0,0.7);margin-left: 2px;color: #fff;opacity: 0.5;}
14      .slideShow .nav span.active{opacity: 1;}
15     </style>
16 </head>
17 <body>
18         <div class="slideShow">
19             <ul>
20                   <li><a href="#"><img src="./images/01.jpg" alt=""></a></li>
21                    <li><a href="#"><img src="./images/02.jpg" alt=""></a></li>
22                     <li><a href="#"><img src="./images/03.jpg" alt=""></a></li>
23                      <li><a href="#"><img src="./images/04.jpg" alt=""></a></li>
24                       <li><a href="#"><img src="./images/05.jpg" alt=""></a></li>
25             </ul>
26             <div class="nav">
27                         <span class="active">1</span>
28                         <span>2</span>
29                         <span>3</span>
30                          <span>4</span>
31                          <span>5</span>
32           </div>
33           <script src="js/jquery-3.1.1.min.js"></script>
34           <script src="js/main.js"></script>
35 </body>
36 </html>

3.main.js代码:

 1 $(document).ready(function(){
 2     var slideShow = $(".slideShow"),         //获取div
 3           ul=slideShow.find("ul"),
 4           nav=slideShow.find(".nav span"),      //获取按钮
 5           oneWidth=ul.find("li").eq(0).width(),
 6           timer=null,
 7           iNow=0;
 8           slideShow.hover(function(){
 9           clearInterval(timer);
10           },autoPlay);
11 
12      nav.on("click",function(){         //添加点击按钮
13          var me=$(this),
14               index=me.index();
15               iNow=index;
16               ul.animate({
17                   "left":- oneWidth * iNow,
18               });      
19         nav.removeClass("active");
20          me.addClass("active");
21      });
22 
23 autoPlay();
24      function autoPlay(){
25          timer = setInterval(function(){
26           iNow++;
27         if(iNow>nav.length-1){
28             iNow=0;
29         }
30           nav.eq(iNow).trigger("click");   
31 },2000);
32 }
33      });

4.效果图

当然了，大小可以利用CSS自己进行调整！
