基于mootools 1.3框架下的图片滑动效果代码

  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

  

复制代码 代码如下:

  <div id="container">

  <img src="http://files.glzy8.com/file_images/article/201104/r_song1.jpg" alt="" />

  <img src="http://files.glzy8.com/file_images/article/201104/r_song2.jpg" alt="" />

  <img src="http://files.glzy8.com/file_images/article/201104/r_song3.jpg" alt="" />

  <img src="http://files.glzy8.com/file_images/article/201104/r_song4.jpg" alt="" />

  <img src="http://files.glzy8.com/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();

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