本文實例講述了jQuery老黃歷實現方法。分享給大家供大家參考。具體實現方法分析如下：
先來看看程序運行效果：
html頁面部分如下：
代碼如下:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>jquery老黃歷特效 -</title>
<script id="jquery_183" type="text/javascript" class="library" src="js/jquery-1.8.3.min.js"></script>

<link rel="stylesheet" href="css/style.css" type="text/css" media="all" />
<body>
<div class="container">
<div class="title">

line-height: 30pt;
text-align: center;
}
.split, .clear {
clear: both;
height: 1px;
overflow-y: hidden;
}
.good, .bad {
clear: both;
position: relative;
}
.bad {
/*top: -1px;*/
}
.good .title, .bad .title {
float: left;

}
.good .title>table, .bad .title>table {

}
.good .title {
background: #ffee44;
}

background: #ff4444;
color: #fff;
}
.good .content, .bad .content {
margin-left: 115px;
padding-right: 10px;
padding-top: 1px;
font-size:15pt;
}

color: #444;
}
.content ul li div.description {
font-size: 10pt;
font-weight: normal;
color: #777;
line-height: 110%;
margin-bottom: 10px;
}
.line-tip {
font-size: 11pt;
margin-top: 10px;
margin-left: 10px;
}
.direction_value {

font-weight: bold;
}
.comment {
margin-top: 50px;
font-size: 11pt;
margin-left: 10px;
}
.comment ul {
margin-left: 0;
padding-left: 20px;
color: #999;
}
almanac.js代碼如下：
代碼如下:
/*
* 注意：本程序中的“隨機”都是偽隨機概念，以當前的天為種子。
*/

var n = dayseed % 11117;
for (var i = 0; i < 100 + indexseed; i++) {
