========================

日期函数列表:  
dateObj.getTime()得到时间,dateObj.getYear()得到年份,dateObj.getFullYear()得到四位的年份  
,dateObj.getMonth()得到月份,dateObj.getDate()得到日,dateObj.getDay()得到日期几,dateObj.getHours()得到小时,dateObj.getMinutes()得到分,dateObj.getSeconds()得到秒,dateObj.setTime(value)设置时间,dateObj.setYear(val)设置年,dateObj.setMonth(val)设置月,dateObj.setDate(val)设置日,dateObj.setDay(val)设置星期几,dateObj.setHours设置小时,dateObj.setMinutes(val)设置分,dateObj.setSeconds(val)设置秒 \[注意:此日期时间从0开始计\]43.FRAME的表示方式: \[window.\]frames\[n\].ObjFuncVarName,frames\["frameName"\].ObjFuncVarName,frameName.ObjFuncVarName

时间对象用来操作日期和时间。

## Date(日期)型字符串，要想正确的转换为Date(日期)对象，必须用new Date(str)方式，直接用Date(str)强制转换将得到错误结果，另外转换时Date字符串的格式为"年/月/日"（也许还有其它写法，这里只测试了yyyy/mm/dd确实是可行的），而另一种很常见的"年-月-日"的表示方式，转换后将得到错误结果  eg:  var a = Date.parse("2009/04/22 16:30");  var now = new Date(a);       举例 ##

[Return today's date and time][Return today_s date and time]  
  
使用Date()方法得到今天的日期

[getTime()][getTime]  
  
用getTime()来计算1970年到现在之间的时间差距

[setFullYear()][setFullYear]  
使用getFullYear()来设置指定的日期

[toUTCString()][toUTCString]  
  
使用UTCString()来将今天的日期转换成字符串（依据UTC）

[getDay()][getDay]  
  
使用getDay()和一数组来书写星期几，并不是简单的数字

[Display a clock][]

## Defining Dates   定义日期 ##

时间对象用来操作日期跟时间

我们通过一个新的关键字来定义一个时间对象。下面的代码行就定义了一个时间对象（称作myDate）:

Note:   
注意：时间对象将自动把当前的日期和时间作为初始值！

--------------------

## Manipulate Dates   操作（设置）时间 ##

我们可以轻易地用有效的时间对象来操作（设置）日期或时间

在下面的例子中我们设置一个时间对象来指定日期（2010年一月14号）:

下面的例子我们将一时间对象设置为未来的5天：

Note:   
注意：如果给一日期增加天改为给月或年增加的话，一些变化会由时间对象自动处理！

--------------------

## Comparing Dates   比较时间（日期） ##

时间对象同样使用在比较两个日期（时间）

下面的例子将今天的日期和2010年1月14号作比较：

--------------------

## Complete Date Object Reference   完整的时间对象参考 ##

For a complete reference of all the properties and methods that can be used with the Date object, go to our [complete Date object reference.][]  
Date\[日期\]对象中的所有属性和方法参数，我们将在[完整Date对象参数][complete Date object reference.] 中罗列说明。

The reference contains a brief description and examples of use for each property and method!  
我们将列举简要 说明 和典型案例来讲解每个参数的属性和方法的用法。

## Date Object Methods   日期对象方法 ##

时间对象是一个我们经常要用到的对象，无论是做时间输出、时间判断等操作时都与这个对象离不开。除开JavaScript中的时间对象外，在VbScript中也有许多的时间对象，而且非常好用。下面还是按照我们的流程来进行讲解。   
它是一个内置对象——而不是其它对象的属性,允许用户执行各种使用日期和时间的过程。   
　方法：分为得到时间方法、设置时间方法和转换时间方法   
得到时间方法：   
　　getDate() 查看Date对象并返回日期   
　　getDay() 返回星期几   
　　getHours() 返回小时数   
　　getMinutes() 返回分钟数   
　　getMonth() 返回月份值   
　　getSeconds() 返回秒数   
　　getTime() 返回完整的时间   
　　getYear() 返回年份   
设置时间方法：   
　　setDate() 改变Date对象的日期   
　　setHours() 改变小时数   
　　setMinutes() 改变分钟数   
　　setMonth() 改变月份   
　　setSeconds() 改变秒数   
　　setTime() 改变完整的时间   
　　setYear() 改变年份   
转换时间方法：   
　　toGMTString() 把Date对象的日期(一个数值)转变成一个GMT时间字符串,返回类似下面的值:Weds,15 June l997 14:02:02 GMT(精确的格式依赖于计算机上所运行的操作系统而变)   
　　toLocaleString() 把Date对象的日期(一个数值)转变成一个字符串,使用所在计算机上配置使用的特定日期格式   
　　UTC() 使用Date UTC(年、月、日、时、分、秒),以自从1970年1月1日00:00:00(其中时、分、秒是可选的)以来的毫秒数的形式返回日期   
几个需要注意的地方：   
1、得到日期和年和设置日期和年时间，其中很怪的问题就是不能对月份进行设置（比较的怪）：   
<script language="javascript">   
d = new Date();   
alert(d.toLocaleString());   
d.setDate(25);   
alert(d.toLocaleString());   
d.setYear(2000);   
alert(d.toLocaleString());   
</script>   
2、获得年的时候最好用getFullYear()方法来做   
3、由于针对月份，JS是从0开始的，因此需要对月份进行操作时要加1   
下面是几个关于时间的经典而且经常会用到的例子，希望对大家会有提高的。谢谢继续关注该帖子。。。   
1、将2005-8-5转换成2005-08-05格式   
<script language="javascript">   
var strDate = '2005-8-5';   
window.alert(strDate.replace(/\\b(\\w)\\b/g, '0$1'));   
</script>   
2、得到间隔天数   
<script type="text/javascript">   
   
</script>   
3、得到间隔时间   
<script>   
var d1=new Date("2004/09/16 20:08:00");   
var d2=new Date("2004/09/16 10:18:03");   
var d3=d1-d2;   
var h=Math.floor(d3/3600000);   
var m=Math.floor((d3-h\*3600000)/60000);   
var s=(d3-h\*3600000-m\*60000)/1000;   
alert("相差"+h+"小时"+m+"分"+s+"秒");   
</script>   
4、得到今天的日期   
<script language="javascript">   
d = new Date();   
alert(d.getFullYear()+"年"+(d.getMonth()+1)+"月"+d.getDate()+"日");   
</script>   
6、数字日期转汉字   
<html>   
<head>   
<title> New Document </title>   
</head>   
<body>   
<script language=javascript>   
Date.prototype.getRead = function()   
\{   
var values = new Array("零", "一", "二", "三", "四", "五", "六", "七", "八", "九");   
var returnValue, temp;   
returnValue = this.getYear()+"年";   
temp = (this.getMonth()+1)+"月"+this.getDate()+"日";   
temp = temp.replace(/(\\d)(\\d)/g,"$1十$2").replace(/1十/g,"十").replace(/十0/g,"十");   
returnValue += temp;   
returnValue = returnValue.replace(/\\d/g, function(sts)\{return values\[parseInt(sts)\]\});   
return returnValue;   
\}   
var t=new Date();   
document.write(t.getRead());   
</script>   
</body>   
</html>   
7、得到前N天或后N天的日期   
方法一：   
<script type="text/javascript">   
function showdate(n)   
\{   
var uom = new Date(new Date()-0+n\*86400000);   
uom = uom.getFullYear() + "-" + (uom.getMonth()+1) + "-" + uom.getDate();   
return uom;   
\}   
window.alert("今天是："+showdate(0));   
window.alert("昨天是："+showdate(-1));   
window.alert("明天是："+showdate(1));   
window.alert("10天前是："+showdate(-10));   
window.alert("5天后是："+showdate(5));   
</script>   
方法二：   
<script type="text/javascript">   
function showdate(n)   
\{   
var uom = new Date();   
uom.setDate(uom.getDate()+n);   
uom = uom.getFullYear() + "-" + (uom.getMonth()+1) + "-" + uom.getDate();   
return uom;   
\}   
window.alert("今天是："+showdate(0));   
window.alert("昨天是："+showdate(-1));   
window.alert("明天是："+showdate(1));   
window.alert("10天前是："+showdate(-10));   
window.alert("5天后是："+showdate(5));   
</script>   
方法三（不好意思，这个市用vsscript做的）：   
<script language="vbscript">   
function showdate(n)   
showdate=dateadd("d",date(),n)   
end function   
msgbox "今天是:"&showdate(0)   
msgbox "昨天是:"&showdate(-1)   
msgbox "明天是:"&showdate(1)   
msgbox "十天前是:"&showdate(-10)   
msgbox "五天后是:"&showdate(5)   
</script>   
方法四：   
<script language="Javascript">   
Date.prototype.getDays=function()\{   
var \_newDate=new Date();   
\_newDate.setMonth(\_newDate.getMonth()+1);   
\_newDate.setDate(0);   
$\_days=\_newDate.getDate();   
delete \_newDate;   
return $\_days;   
\}   
function showdate(n)   
\{   
var uom = new Date();   
uom.setDate(uom.getDate()+n);   
uom = uom.getFullYear() + "-" + (uom.getMonth()+1) + "-" + uom.getDate()+"\\n星期"+('天一二三四五六'.charAt(uom.getDay()))+"\\n本月有"+ uom.getDays()+"天";   
return uom;   
\}   
window.alert("今天是："+showdate(0));   
window.alert("昨天是："+showdate(-1));   
window.alert("明天是："+showdate(1));   
window.alert("10天前是："+showdate(-10));   
window.alert("5天后是："+showdate(5));   
</script>
