本文为大家介绍下实现JS幻灯片可循环播放带滚动导航可平滑旋转的全过程，效果还不错，由需要的朋友可以参考下，希望对大家有所帮助
最近在帮别人改一些东西,在网上找了好久,但是没有相同的,自己改了下,拿出来分享下：
先展示下效果把：
index.html 页面展示代码
复制代码 代码如下:

OK，最后加上一些样式上的东西,就可以跑起来了；
复制代码 代码如下:
body {
margin: 0px; padding: 0px;
}
div {
margin: 0px; padding: 0px;
}
ul {
margin: 0px; padding: 0px;
}
li {
margin: 0px; padding: 0px;
}
h4 {
margin: 0px; padding: 0px;
}
p {
margin: 0px; padding: 0px;
}
body {
no-repeat 50% 0px rgb(0, 0, 0); font: 12px/1.8 arial; color: rgb(255, 255, 255); font-size-adjust: none; font-stretch: normal;
}
a {
background: rgb(102, 102, 102); padding: 2px 5px; color: rgb(255, 255, 255); text-decoration: none;
}
a:hover {
background: rgb(255, 153, 0);
}
#box {
margin: 1px auto 0px; width: 680px; height: 320px; position: relative;
}
#box ul {
width: 680px; height: 320px; position: relative;
}
#box li {

}
#box li div {
background: rgb(0, 0, 0); width: 100%; height:40px; bottom: -100px; position: absolute; opacity: 0.7;
}
#box li div h4 {

}
#box li div h4 span {
color: red; margin-left: 10px;
}
#box li div p {
margin: 5px 10px 0px; text-indent: 2em;
}
.numbutLeft{width: 15px; height: 5px; background-color:#AFB7B6; float: left; cursor: pointer;}
.numbut{width: 15px; height: 5px; background-color:#AFB7B6; float: left; margin-left: 5px; cursor: pointer;}

.numbutLeftCen{width: 15px; height: 5px; background-color:#FF0000; float: left; cursor: pointer;}
.numbutdiv{height: 10px;width: 100%;color: red;margin-top: 0px; padding-top: 0px}
.ndv{height: 10px;width: 95px; margin: 0 auto}
#box .next {
background-position: -39px 0px; right: -60px;
}
#copyright {
text-align: center; padding-top: 10px;
}
OOOOOKKK 了,奇特的效果就要出来了 ,还有一些不完美的地方,懒得去改了,有高手可以改改看,但希望分享哦。
效果如下:
