方法一：

1.css样式代码：

<style>
        div{
            width: 344px;
            height: 199px;
            overflow: hidden;
        }
        ul{
            width: 1042px;
        }
        li{
            display: inline-block;
        }
    </style>

2.html代码：

 <div class="wrapper">
        <ul>
            <li><img src="07.gif"></li>
            <li><img src="08.gif"></li>
            <li><img src="09.gif"></li>
        </ul>
    </div>

3.js代码：

<script src="http://apps.bdimg.com/libs/jquery/1.11.1/jquery.js"></script>
    <script>

        var imgWidth = $(".wrapper").width();//ul移动一次的距离
        var imgLength = $("ul li").length;//判断索引为最后一个时，重新置为0
        var index = 0;//索引

        function changeImg(direction){
            if(direction == "left"){
                index++;
            }else{
                index--;
            }
            if(index == imgLength){
                index=0;
            }else if(index == -1){
                index=imgLength-1;
            }
            $("ul").stop().animate({
                marginLeft:-index*imgWidth+"px",
            },600)
        }

        function autoMove(){
            setInterval(function(){
                changeImg("left");

            },2000)
        }
        autoMove();
    </script>

方法二：

 效果图：

  注释：该方法实现的轮播图是可循环的。

1.css代码：

.wrapper{
     100%;
    height: 200px;
    overflow: hidden;
    position: absolute;
}
.wrapper ul{
     400%;
    height: 200px;
    font-size: 0;
    position: relative;
}
.wrapper ul li{
    display: inline-block;

}
.wrapper img{
     100%;
    height:200px;
}
.wrapper .dots{
    position: absolute;
    right: 5px;
    top:180px;
}
.wrapper .dots span{
     16px;
    height: 16px;
    display: inline-block;
    background: #FFF;
    opacity: .5;
    border-radius: 50%;
}

2.HTML代码：

<div class="wrapper">
        <ul>
            <li><img src="img/4-1.jpg"/></li>
            <li><img src="img/4-2.jpg"/></li>
            <li><img src="img/4-3.jpg"/></li>
            <li><img src="img/4-4.jpg"/></li>
        </ul>
        <div class="dots">
            <span></span>
            <span></span>
            <span></span>
            <span></span>
        </div>
    </div>

3.js代码：

<script src="js/zepto.js"></script>
    <script>
        var index = 1;
        var liLnegth = $("li").length;
        $(".dots span").eq(0).css("opacity","1");
        setInterval(function(){
            $("ul").css("left","0%");
            $("ul").animate({
                left:-100+"%"
            },1000)
            $(".dots span").eq(index-1).css("opacity",".5");
            $(".dots span").eq(index).css("opacity","1");
            $("ul li").eq(0).remove().clone(true).appendTo($("ul"));
            index ++;
            if(index == liLnegth){index = 0}
        },2000);
    </script>

方法三：

借助touchSlide插件   注释：该方法在移动端可以手动左右滑动，但是不可循环

1.css代码：

.focus {
   100%;
  height: 140px;
  margin: 0 auto;
  position: relative;
  overflow: hidden;
}
.focus .hd {
   100%;
  height: 11px;
  position: absolute;
  z-index: 1;
  bottom: 5px;
  text-align: center;
}
.focus .hd ul {
  display: inline-block;
  height: 5px;
  padding: 3px 5px;
  background-color: rgba(255, 255, 255, 0.7);
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  border-radius: 5px;
  font-size: 0;
  vertical-align: top;
}
.focus .hd ul li {
  display: inline-block;
   5px;
  height: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  border-radius: 5px;
  background: #8C8C8C;
  margin: 0 5px;
  vertical-align: top;
  overflow: hidden;
}
.focus .hd ul .on {
  background: #FE6C9C;
}
.focus .bd {
  position: relative;
  z-index: 0;
}
.focus .bd li img {
   100%;
  height: 140px;
}

/* 修改   */
.focus .hd { 
  text-align: right;
  bottom: 10px;
}
.focus .hd ul { 
  background-color: transparent;
}
.focus .hd ul li {  
   10px;
  height: 10px;
  -webkit-border-radius: 10px;
  opacity: 0.6;
}
.focus .hd ul .on {
  background: #fff;
  opacity: 1;
}

注释：css代码部分有所修改

2.html代码：

<div id="banner" class="focus">
                <div class="hd">
                    <ul></ul>
                </div>
                <div class="bd">
                    <ul>
                            <li><a href="#"><img _src="img/商城banner.jpg"  /></a></li>
                            <li><a href="#"><img _src="img/商城banner.jpg" /></a></li>
                            <li><a href="#"><img _src="img/商城banner.jpg" /></a></li>
                    </ul>
                </div>
            </div>

3.js代码：

<script type="text/javascript" src="js/zepto.js" ></script>
    <script type="text/javascript" src="js/TouchSlide.1.1.js" ></script>
    <script type="text/javascript">
                TouchSlide({ 
                    slideCell:"#banner",
                    titCell:".hd ul", //开启自动分页 autoPage:true ，此时设置 titCell 为导航元素包裹层
                    mainCell:".bd ul", 
                    effect:"left", 
                    autoPlay:true,//自动播放
                    autoPage:true, //自动分页
                    switchLoad:"_src" //切换加载，真实图片路径为"_src" 
                });
            </script>

方法四：

借助swipe插件

注释：和touchsilde插件的效果一样

1.css代码：

<style type="text/css">
        .swipe{
            overflow: hidden;
            visibility: hidden;
            position: relative;
        }
        .swipe-wrap{
            overflow: hidden;
            position: relative;
        }
        .swipe-wrap > div{
            float: left;
            width: 100%;
            position: relative;
        }
        .swipe-wrap > div img{
            width: 100%;
            height: 220px;
        }
    </style>

2.HTML代码：

<div id="slider" class="swipe">
            <div class="swipe-wrap">
                <div class="wrap">
                    <img src="img/3-1.jpg">
                </div>
                <div class="wrap">
                    <img src="img/3-2.jpg">
                </div>
                <div class="wrap">
                    <img src="img/3-3.jpg">
                </div>
            </div>
        </div>

3.js代码：

<script src="js/zepto.js"></script>
        <script src="js/swipe.js" type="text/javascript" charset="utf-8"></script>
        <script type="text/javascript">
            window.mySwipe=Swipe(document.getElementById('slider'),{
                startSlide: 2,   
                speed: 400,   
                auto: 3000,   
                continuous: true,   
                disableScroll: false,   
                stopPropagation: false,   
                callback: function(index, elem) {},   
                transitionEnd: function(index, elem) {}
            });
        </script>

方法五：借助swipe插件   注释：该方法可以自动循环播放

1.swipe.css代码：

/*轮播*/
.carousel{
  height:250px; 
  position: relative;
}

.carousel .swipe {
  overflow: hidden;
  visibility: hidden;
  position: relative;
  height: 100%;
}

.carousel .swipe .swipe-wrap {
  overflow: hidden;
  position: relative;
}

.carousel .swipe .swipe-wrap > figure {
  float: left;
   100%;
  position: relative;
}

#slider{
  max- 650px;
  /* 设置最大的宽度 */
  margin: 0px auto;
  /* 居中对齐 */
}
figure {
  margin: 0;
  /* 对齐，四周宽度都为0，在轮播的时候，以整张图片进行移动 */
}
.face{
  height: 250px;/*设置图片高度*/
}

/*底边小点的设置*/
.carousel nav #position {
  text-align: center;
  list-style: none;
  margin: 0;
  padding: 0;
  position: absolute;
  bottom: 5px;
}

.carousel nav #position li {
  display: inline-block;
   10px;
  height: 10px;
  border-radius: 10px;
  background: #141414;
  box-shadow: inset 0 1px 3px black, 0 0 1px 1px #202020;
  margin: 0 2px;
  cursor: pointer
}

.carousel nav #position li.on {
  box-shadow: inset 0 1px 3px -1px #28b4ea, 0 1px 2px rgba(0, 0, 0, .5);
  background-color: #1293dc;
  background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #1293dc), color-stop(100%, #0f6297));
  background-image: -webkit-linear-gradient(top, #1293dc, #0f6297);
  background-image: -moz-linear-gradient(top, #1293dc, #0f6297);
  background-image: -ms-linear-gradient(top, #1293dc, #0f6297);
  background-image: -o-linear-gradient(top, #1293dc, #0f6297);
  background-image: linear-gradient(top, #1293dc, #0f6297)
}

2.html代码：

<div class="carousel">
      <div id="slider" class="swipe" style="visibility:visible;">
        <div class="swipe-wrap">
          <figure>
            <div class="face faceInner">
              <img src="img/4-1.jpg" width="100%" height="100%" />
            </div>
          </figure>
          <figure>
            <div class="face faceInner">
              <img src="img/4-2.jpg" width="100%" height="100%" />
            </div>
          </figure>
          <figure>
            <div class="face faceInner">
              <img src="img/4-3.jpg" width="100%" height="100%" />
            </div>
          </figure>
          <figure>
            <div class="face faceInner">
              <img src="img/4-4.jpg" width="100%" height="100%" />
            </div>
          </figure>
        </div>
      </div>
      <nav>
        <ul id="position">
          <li class="on"></li>
          <li></li>
          <li></li>
          <li></li>
        </ul>
      </nav>
    </div>

3.js代码：

<script src="js/swipe.js" type="text/javascript" charset="utf-8"></script>
    <script type="text/javascript">
      var slider = Swipe(document.getElementById('slider'), {
        auto: 3000,//轮播时间
        continuous: true,//是否连续播放
        disableScroll: false,
        callback: function(pos) {
          var i = bullets.length;
          while (i--) {
            bullets[i].className = ' ';
          }
          bullets[pos].className = 'on';
        }
      });
      var bullets = document.getElementById('position').getElementsByTagName('li');
    </script>
