仿谷歌主页js动画效果实现代码

  源代码:

  

复制代码 代码如下:

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  <html xmlns="http://www.w3.org/1999/xhtml">

  <head>

  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

  <title>谷歌主页动画</title>

  <style type="text/css">

  .animate{

  height:156px;

  width:97px;

  background:url(images/gumby11-gumby.jpg) no-repeat;

  background-position:-15581px center;

  }

  </style>

  <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>

  <script type="text/javascript">

  $(function(){

  var offset = -15678;

  $('#start').click(function(){

  var timer = setInterval(function(){

  offset += 98;

  $('#animate').css({

  'background-position':offset + 'px center'

  });

  if(offset > 0){

  clearInterval(timer);

  }

  },50);

  $(this).hide();

  });

  });

  </script>

  </head>

  <body>

  <div id="animate" class="animate"></div>

  <a id="start" href="javascript:void(0)">动起来吧!</a>

  </body>

  </html>

  其实这动画不难,难在那种图片上,不知道这图片是怎么做出来的!!!
