jQuery老黄历完整实现方法

本文实例讲述了jQuery老黄历实现方法。分享给大家供大家参考。具体实现方法分析如下：

先来看看程序运行效果：

html页面部分如下：


<!DOCTYPE html>

<html>

 <head>

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

  <title>jquery老黄历特效 -</title>

 <script type="text/javascript" class="library" src="js/almanac.js"></script>

 </head>

 <link rel="stylesheet" href="css/style.css" type="text/css" media="all" />

 <body>

  <div class="container">

   <div class="title">
