兄弟们,有没有好点的JS日期计算函数什么的

a=new Date()
b=Date.parse(a)+5*24*60*60*1000
b =new Date(b)
没有现成的

唉,郁闷啊,算了，就当我放分了，谁有好的意见尽管提我已经自己写WEB服务用JS调用了,用C#算吧.------------------------------------------------------------
啊，两个都不错哦.

function dateadd(date1,day)
{
    var T=new Date();
    if(day<0)day=0;
    var t=Date.parse(date1)+day*1000*3600*24;
    T.setTime(t);
    return T;
}

呵呵，runmin(★★★★★)，要晕了？
要不要给你让出一块地来躺着呢，
你太搞笑了吧？！

........................还是个MM啊,大家,我好不容易问回问题多顶几个啦.比如说
Date.AddDay()
Date.AddMonth()
Date.AddYear()
Date.AddHours()
.
.
.这样用起来也方便嘛,难道真的没有一个人有这么完整的了?要知道.NET中提供的方法有很多啦.也只有这么完整的才值200分啊,要不别人还不以为我倒分啊?实在没有，也只能大家来顶，我散分咯.

见过网页上太多的js写的显示时间的方法，但是Js日期计算函数，例如取两个时间之间的差值、输入时间范围的正确性这类判断这样的JS自带的函数没有怎么见过。

runmin(★★★★★) ,你在这里呀，我来支持一下。js里面没见过直接用的方法，看来只有自己写了。我看就用孟子的方法也很简单嘛。
