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 id="jquery_183" type="text/javascript" class="library" src="js/jquery-1.8.3.min.js"></script>
 </head>
 <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">
    程序员老黄历<sup>beta</sup>
   </div>
   <div class="date">
   </div>
   <div class="good">
    <div class="title">
     <table>
      <tr><td>宜</td></tr>
     </table>
    </div>
    <div class="content">
     <ul></ul>
    </div>
    <div class="clear"></div>
   </div>
   <div class="split"></div>
   <div class="bad">
    <div class="title">
     <table>
      <tr><td>不宜</td></tr>
     </table>
    </div>
    <div class="content">
     <ul></ul>
    </div>
    <div class="clear"></div>
   </div>
   <div class="split"></div>
   <div class="line-tip">
    <strong>座位朝向：</strong>面向<span class="direction_value"></span>写程序，BUG 最少。
   </div>
   <div class="line-tip">
    <strong>今日宜饮：</strong><span class="drink_value"></span>
   </div>
   <div class="line-tip">
    <strong>女神亲近指数：</strong><span class="goddes_value"></span>
   </div>
   
  </div>
 </body>
</html>

style.css样式如下：

复制代码代码如下:

body * {
font-family:"Consolas","Microsoft Yahei", Arial, sans-serif;
}

body {
background: white;
margin: 0;
padding: 0;
}

.container {
width: 320px;
margin: 0 auto 50px;
}

.container>.title {

padding: 5px 15px;
}

.date{
font-size:17pt;
font-weight: bold;
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;
width: 100px;
font-weight: bold;
text-align: center;
font-size: 30pt;
position:absolute;
top:0;

}

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

}

.good .title {

padding-top: 1px;
font-size:15pt;
}

.good {

}

.bad {

}

.content ul {
list-style: none;
margin:10px 0 0;
padding:0;
}

.content ul li {
line-height:150%;
font-size: 15pt;
font-weight: bold;
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 {
color:#4a4;
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代码如下：

复制代码代码如下:

/*
* 注意：本程序中的“随机”都是伪随机概念，以当前的天为种子。
*/
function random(dayseed, indexseed) {
var n = dayseed % 11117;
for (var i = 0; i < 100 + indexseed; i++) {
n = n * n;
n = n % 11117; // 11117 是个质数
}
return n;
}

var today = new Date();
var iday = today.getFullYear() * 10000 + (today.getMonth() + 1) * 100 + today.getDate();

var specials = [
{date:20130221, type:'good', name:'防核演习', description:'万一哪个疯子丢颗核弹过来...'}
];

var tools = ["Eclipse写程序", "MSOffice写文档", "记事本写程序", "Windows8", "Linux", "MacOS", "IE", "Android设备", "iOS设备"];

var varNames = ["jieguo", "huodong", "pay", "expire", "zhangdan", "every", "free", "i1", "a", "virtual", "ad", "spider", "mima", "pass", "ui"];

var drinks = ["水","茶","红茶","绿茶","咖啡","奶茶","可乐","牛奶","豆奶","果汁","果味汽水","苏打水","运动饮料","酸奶","酒"];

function getTodayString() {
return "今天是" + today.getFullYear() + "年" + (today.getMonth() + 1) + "月" + today.getDate() + "日星期" + weeks[today.getDay()];
}

// 生成今日运势
function pickTodaysLuck() {
var numGood = random(iday, 98) % 3 + 2;
var numBad = random(iday, 87) % 3 + 2;
var eventArr = pickRandomActivity(numGood + numBad);
var specialSize = pickSpecials();
for (var i = 0; i < numGood; i++) {
addToGood(eventArr[i]);
}
for (var i = 0; i < numBad; i++) {
addToBad(eventArr[numGood + i]);
}
}

// 添加预定义事件
function pickSpecials() {
var specialSize = [0,0];

for (var i = 0; i < specials.length; i++) {
  var special = specials[i];

  if (iday == special.date) {
   if (special.type == 'good') {
    specialSize[0]++;
    addToGood({name: special.name, good: special.description});
   } else {
    specialSize[1]++;
    addToBad({name: special.name, bad: special.description});
   }
  }
}
return specialSize;
}

// 从 activities 中随机挑选 size 个
function pickRandomActivity(size) {
var picked_events = pickRandom(activities, size);
for (var i = 0; i < picked_events.length; i++) {
picked_events[i] = parse(picked_events[i]);
}
return picked_events;
}

// 从数组中随机挑选 size 个
function pickRandom(array, size) {
var result = [];
for (var i = 0; i < array.length; i++) {
  result.push(array[i]);
}
for (var j = 0; j < array.length - size; j++) {
  var index = random(iday, j) % result.length;
  result.splice(index, 1);
}
return result;
}

// 解析占位符并替换成随机内容
function parse(event) {
var result = {name: event.name, good: event.good, bad: event.bad}; // clone
if (result.name.indexOf('%v') != -1) {
  result.name = result.name.replace('%v', varNames[random(iday, 12) % varNames.length]);
}
if (result.name.indexOf('%t') != -1) {
  result.name = result.name.replace('%t', tools[random(iday, 11) % tools.length]);
}
if (result.name.indexOf('%l') != -1) {
  result.name = result.name.replace('%l', (random(iday, 12) % 247 + 30).toString());
}
return result;
}

// 添加到“宜”
function addToGood(event) {
$('.good .content ul').append('<li><div class="name">' + event.name + '</div><div class="description">' + event.good + '</div></li>');
}

// 添加到“不宜”
function addToBad(event) {
$('.bad .content ul').append('<li><div class="name">' + event.name + '</div><div class="description">' + event.bad + '</div></li>');
}

$(function(){
$('.date').html(getTodayString());
$('.direction_value').html(directions[random(iday, 2) % directions.length]);
$('.drink_value').html(pickRandom(drinks,2).join());
$('.goddes_value').html(random(iday, 6) % 50 / 10.0);
pickTodaysLuck();
});

希望本文所述对大家的jQuery程序设计有所帮助。
