示例一：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>TT</title>
<script src="jquery.js"></script>
</head>
<body>
<p style="line-height: 50%;"><span></span></p>
<input type="button" value="轻轻" onclick="syncTime()">
<script>
function syncTime(){
var mydate = new Date();
var week;
switch (mydate.getDay()){
case 1: week="星期一"; break;
case 2: week="星期二"; break;
case 3: week="星期三"; break;
case 4: week="星期四"; break;
case 5: week="星期五"; break;
case 6: week="星期六"; break;
default: week="星期天";
}
var str = "" + mydate.getFullYear() + " 年 " + (mydate.getMonth() + 1) + " 月 " + mydate.getDate() + " 日 " + week;
$('.todaytime')[0].innerHTML = str;
str = '"savesynctime" : "' + str + '"'
return str;
}
console.log(syncTime());
</script>
</body>
</html>
示例二：
<script type="text/javascript">
var date = new Date();
document.writeln(date);
//Thu Jan 08 2015 01:25:53 GMT+0800 (中国标准时间)
document.writeln(Date.parse());
//NaN
document.writeln(Date.parse('6/10/2014'));
//1402329600000 毫秒数
document.writeln(Date.parse('Thu Jan 08 2015 01:25:53'));
//1420651553000 毫秒数
document.writeln(Date.UTC());
//NaN
//日期格式化方法
document.writeln('<br/>');
document.writeln(date.toDateString());
//Thu Jan 08 2015
document.writeln('<br/>')
document.writeln(date.toTimeString());
//01:39:08 GMT+0800 (中国标准时间)
document.writeln('<br/>')
document.writeln(date.toLocaleDateString());
//2015年1月8日
document.writeln('<br/>')
document.writeln(date.toLocaleTimeString());
//上午1:39:08
document.writeln('<br/>')
document.writeln(date.toUTCString());
//Wed, 07 Jan 2015 17:39:08 GMT
//一些set，get方法
</script>
示例三：
Date.prototype.Format = function(formatStr) {
var str = formatStr;
var Week = ['日', '一', '二', '三', '四', '五', '六'];
str = str.replace(/yyyy|YYYY/, this.getFullYear());
str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));
str = str.replace(/MM/, (this.getMonth() + 1) > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));
str = str.replace(/M/g, (this.getMonth() + 1));
str = str.replace(/w|W/g, Week[this.getDay()]);
str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate());
str = str.replace(/d|D/g, this.getDate());
str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours());
str = str.replace(/h|H/g, this.getHours());
str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes());
str = str.replace(/m/g, this.getMinutes());
str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds());
str = str.replace(/s|S/g, this.getSeconds());
return str
}

console.log(d.toString("")); //2014-7-27 9:26:52
console.log(d.toString("yyyy-MM-dd HH:mm:ss")); //2014-07-27 09:26:52
console.log(d.toString("yyyy年MM月dd日 HH:mm:ss")); //2014年07月27日 09:26:52
console.log(d.toString("yyyy-MM-dd HH:mm:ss fff")); //2014-07-27 09:26:52 237
console.log(d.toString("yyyy年 MMM dd EEE")); //2014年 七月 27 星期五

示例五：时间个性化输出功能
/*
1、< 60s, 显示为“刚刚”
2、>= 1min && < 60 min, 显示与当前时间差“XX分钟前”
3、>= 60min && < 1day, 显示与当前时间差“今天 XX:XX”
4、>= 1day && < 1year, 显示日期“XX月XX日 XX:XX”
5、>= 1year, 显示具体日期“XXXX年XX月XX日 XX:XX”
*/
