实现原理:
bet36365注册送奖金,容器采用相对定位,图片采用绝对定位,当鼠标移动到相应的图片上,改变去left属性,用tween实现动画效果.

代码分析:写一个picSlider类实现代码封装

复制代码 代码如下:

<div id=”container”>
<img src=”//files.jb51.net/file_images/article/201104/r_song1.jpg”
alt=”” />
<img src=”//files.jb51.net/file_images/article/201104/r_song2.jpg”
alt=”” />
<img src=”//files.jb51.net/file_images/article/201104/r_song3.jpg”
alt=”” />
<img src=”//files.jb51.net/file_images/article/201104/r_song4.jpg”
alt=”” />
<img src=”//files.jb51.net/file_images/article/201104/r_song5.jpg”
alt=”” />
</div>

CSS样式

复制代码 代码如下:

#container{width:459px; height:200px;
background-color:Black;position:relative;overflow:hidden;}
#container img{position:absolute;
width:360px;height:300px;display:block;top:0;width:280px;height:200px;}

JS:picSlider类

复制代码 代码如下:

var picSlider = new Class({
Implements: Options,
options: {
container: “container”,
imgsWidth: 0.6,
},
initialize: function (options) {
this.setOptions(options);
this.container = $(this.options.container);
this.triggers = this.container.getElementsByTagName(“img”);
this.containerWidth = this.container.getSize().x; //get container’s
width
this.imgWidth = this.containerWidth * this.options.imgsWidth;
this.aveWidth = this.containerWidth / this.triggers.length;
this.newAveWidth = (this.containerWidth – this.imgWidth) /
(this.triggers.length – 1);
this.setImgsInit(); //初始化图片展示
this.start();
},
setImgsInit:function(){
for(var i=0;i<this.triggers.length;i++){
this.triggers[i].setStyle(“left”,i*this.aveWidth);
}
},
start:function(){
for(var i=0;i<this.triggers.length;i++){
this.triggers[i].set(“tween”,{property:”left”,duration:300, fps:80});
//为每个元素设置动画参数
this.triggers[i].addEvent(“mouseover”,this.slider.bindWithEvent(this,[i]));//绑定slider函数
}
},
slider:function(e,at){
e.stop();
for(var i=1;i<this.triggers.length;i++){
if(i<=at){
this.triggers[i].get(“tween”).start(i*this.newAveWidth);
}else{
this.triggers[i].get(“tween”).start(this.imgWidth+(i-1)*this.newAveWidth);
}
}
}
});
new picSlider();

如果想直接在本地运行,请引入
<script type=”text/javascript”
src=”https://ajax.googleapis.com/ajax/libs/mootools/1.3.1/mootools-yui-compressed.js"&gt;&lt;/script&gt;
<script type=”text/javascript”
src=”home.js”></script>这个脚本必须在<div><div>后面,原因不解释!
