基于mootools 1.3框架下的图片滑动效果代码

效果预览如下:

实现原理:
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

<div id="container"> 
<img src="//img.jbzj.com/file_images/article/201104/r_song1.jpg" alt="" /> 
<img src="//img.jbzj.com/file_images/article/201104/r_song2.jpg" alt="" /> 
<img src="//img.jbzj.com/file_images/article/201104/r_song3.jpg" alt="" /> 
<img src="//img.jbzj.com/file_images/article/201104/r_song4.jpg" alt="" /> 
<img src="//img.jbzj.com/file_images/article/201104/r_song5.jpg" alt="" /> 
</div>

CSS样式

#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

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"></script>
<script type="text/javascript" src="home.js"></script>这个脚本必须在<div><div>后面，原因不解释！
