我写了一个有用的。


函数nextFriday（）

{

var d = new Date（）;


开关（d.getDay（））

{

案例0：d.setDate（d.getDate（）+ 5）;

休息;


案例1：d.setDate（d.getDate（）+ 4）;

break;


案例2：d.setDate（d.getDate（）+ 3）;

休息;


案例3 ：d.setDate（d.getDate（）+ 2）;

break;


case 4：d.setDate（d.getDate（）+ 1 ）;

休息;


案例6：d.setDate（d.getDate（）+ 6）;

break;

}


返回d;


}

I wrote one that works.

function nextFriday()
{
var d = new Date();

switch (d.getDay())
{
case 0: d.setDate(d.getDate() + 5);
break;

case 1: d.setDate(d.getDate() + 4);
break;

case 2: d.setDate(d.getDate() + 3);
break;

case 3: d.setDate(d.getDate() + 2);
break;

case 4: d.setDate(d.getDate() + 1);
break;

case 6: d.setDate(d.getDate() + 6);
break;
}

return d;

}

寻找一个简单的功能来返回星期五的日期。
我不时发送电子邮件，我想要一个动态返回日期的功能为了星期五。所以无论我发送的是什么，它都会动态计算星期五的日期。此外，如果我在星期五发送它，我想返回当前日期，星期六
以后将返回下周五的日期。感谢您的任何建议。

亲切的问候，
CK

Hi All,
Looking for a simple function to return the date for the follwing Friday.
I send out emails from time to time and I would like a function that
dynamically returns the date for the follwing Friday. So no matter what
day I send it, it will dynamically calculate Friday''s date. Also if I am
sending it on a Friday, I would like to return the current date, Saturday
and later will return next Friday''s date. Thanks for any advice.

Kind Regards,
CK

函数nextDay（day）{

var d =新日期;

（ day =（Math.abs（+ day || 0）％7） - d.getDay（））< 0&& （日+ = 7）;

返回日&& d.setDate（d.getDate（）+ day），d;

};


day参数的范围是0到6.

var d = new Date（）;
d.setDate（d.getDate（）+（12-d.getDay（））％7 ）;

d现在是当前日期，如果它是星期五或下个星期五的日期。

var d=new Date();
d.setDate(d.getDate()+(12-d.getDay())%7);

d is now the current date if it is Friday or the date of the next Friday.

噢，到底是什么，这是'基于for循环的另一个：


for（var x = new Date（）; x.getDay（）！= 5; x.setDate（x.getDate（ ））））}} {}

alert（''下周五是'''+ x.getDate（））;

Aw, what the heck, here''s another based on a for loop:

for (var x=new Date(); x.getDay()!=5; x.setDate(x.getDate()+1)){}
alert(''Next Friday is ... '' + x.getDate());
