图片滑动slider

代码非原创，自己有改动

当改为垂直切换时，要将container的width设为一张图片的宽度，此时图片的排列是垂直的，切换时才会一张换一张

<style type="text/css">
	.main {margin:0; padding:0;width:300px; height:140px; position:relative;overflow: hidden;}
	.container, .container *{margin:0; padding:0;}
	.container{width:1500px; height:140px; position:relative;}
	.slider{position:relative;}
	.slider li{
	list-style:none;
	list-style-image:inherit;
	display:block;
	float: left;
	color: #004985;
	text-align: center;
	line-height: 20px;
	font-size: 16px;
	cursor:pointer;
	overflow:hidden;
	// background-color: #ddd;
	}
	.slider img{ width:300px; height:120px; display:block;border:0;list-style: none;}
	.num{ position:absolute; width: 600px;left:5px; bottom:0px;}
	.num li{
	float: left;
	list-style:none;
	color: #004985;
	text-align: center;
	line-height: 20px;
	width: 20px;
	height: 20px;
	font-family: Arial;
	font-size: 20px;
	cursor: pointer;
	overflow: hidden;
	margin-right: 245px;
	filter:alpha(opacity=80);
	-moz-opacity:0.8;
	}
	</style>

num里的li本来是放数字的，我给改成左右箭头切换了，原来js是这样的

window.onload=function(){
	this._pinNum = 5; //图数
	this._movNum = 126; //距离
	function Each(list, fun){
	for (var i = 0, len = list.length; i < len; i++) { fun(list[i], i); }
	};
	var objs = $("idNum").getElementsByTagName("li");
	var tv = new TransformView("idTransformView", "idSlider",this._movNum,this._pinNum , {
	onStart : function(){ Each(objs, function(o, i){ o.className = tv.Index == i ? "on" : ""; }) }//按钮样式
	});
	tv.Start();
	Each(objs, function(o, i){
	o.onmouseover = function(){
	o.className = "on";
	tv.Auto = true;
	tv.Index = i;
	tv.Start();
	}
	o.onmouseout = function(){
	o.className = "";
	tv.Auto = true;
	tv.Start();
	}
	})
	}

因为我要放在wap上运行，所以onmouseover有点不好控制，给改成onclick了
