https://loading.io ------ 进度条小图标的制做网站javascript

经过加载状态事件制做进度条：
document.onreadystatechange页面加载状态改变时的事件；
document.readyState返回当前文档的状态（uninitialized--还未开始载入；loading--载入中；interactive--已加载，文档与用户能够开始交互；complete--载入完成）

e.g.<!DOCTYPE ht<html lang="en">

<head>

 <meta charset="UTF-8">
 <title>进度条2</title>
 <style type="text/css"> //添加进度条的样式
 .loading{
 width: 100%;
 height: 100%;
 position: fixed;
 left: 0;
 top: 0;
 z-index: 100;
 background: #ffffff;

 } .loading .pic{ width: 64px; height: 64px; border: 1px solid red; background: url("images/loading.gif"); /*剧中显示*/ position: absolute; top: 0; bottom: 0; left: 0; right: 0; margin: auto; } </style>//引入jquery包 <script type="text/javascript" src="jquery-1.3.1.js"></script> <script type="text/javascript">// 页面加载状态改变时的事件 document.onreadystatechange = function () { if(document.readyState == 'complete'){ //判断页面加载完成，加载的图标就隐藏 $(".loading").fadeOut(); } } </script></head><body> <div class="loading"> <div class="pic"></div> //加载图标的显示 </div> <img src="http://pic29.nipic.com/20130514/12477194_083818249176_2.jpg" alt=""> <img src="http://pic37.nipic.com/20140115/9448607_120900609000_2.jpg" alt=""> <img src="http://pic.58pic.com/58pic/11/15/53/43g58PICz9B.jpg" alt=""> <img src="http://pic3.nipic.com/20090519/2390580_090051082_2.jpg" alt=""> <img src="http://pic25.nipic.com/20121127/9026859_131523397124_2.jpg" alt=""> <img src="http://pic29.nipic.com/20130514/12477194_083818249176_2.jpg" alt=""></body></html>
