封装图片滑动效果

by bopooo

在腾讯QQ软件下载的页面有一个图片滑动的效果，觉得还不错就自己封装了一个
技术方面在动作缓冲上遇到一些问题不过都解决了
不过还是要谢谢天空里的一片云给我提供的资料http://bbs.blueidea.com/thread-2961061-1-2.html
我大体上看了下别人的思路就自己动手做了基本上是按照自己的想法来做的

考虑到很多朋友不太了解js 所以我封装的时候把所有参数都集中到一个函数里免得大家调用的时候还要看源代码去设置参数根据提供不同的参数会有不同的效果没有封装特别多的效果需要的朋友可以自己动手改正自己想要的
废话多了具体看效果

调用方法：glide.layerGlide(auto,oEventCont,oSlider,sSingleSize,second ,fSpeed,point);

*glide.layerGlide(auto,oEventCont,oSlider,sSingleSize,second ,fSpeed,point);
*@param auto type:bolean 是否自动滑动当值是true的时候为自动滑动
*@param oEventCont type:object 包含事件点击对象的容器
*@param oSlider type:object 滑动对象
*@param sSingleSize type:number 滑动对象里单个元素的尺寸（width或者height）尺寸是有point 决定
*@param second type:number 自动滑动的延迟时间单位/秒
*@param fSpeed type:float 速率取值在0.05--1之间当取值是1时没有滑动效果
*@param point type:string left or top 当值为left 为横向滚动为top是顺向滚动

横向滑动
