图片滑动slider

大大源码 • • 其他

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;

  }
   
  </script>

 

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.οnlοad=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
