After Effects 脚本 - 星期几

Question

我正在尝试修改一个简单的小AE脚本，该脚本在源文本中显示星期几。我需要它显示明天和第二天 - 我可以通过使用 +1 和 +2 来完成 - 但没有条件它会中断。我猜它是沿着这样的路线;如果 d>6 则 d=0？不能完全正确编写代码，将不胜感激！

d = new Date(Date(0));
var weekday=new Array(7);
weekday[0]="Sunday";
weekday[1]="Monday";
weekday[2]="Tuesday";
weekday[3]="Wednesday";
weekday[4]="Thursday";
weekday[5]="Friday";
weekday[6]="Saturday";
weekday[d.getDay()]

Answer 1

[编辑：非常抱歉，@ndix，但以前的代码（已删除）完全有缺陷。底片将不起作用。使用以下代码]

timeDirectionIndex = 0;//initial for today or future
daysToAdd = -15;//you can make this zero or any positive or negative integer
d = new Date(Date(0));
var weekday=new Array(7);
if (daysToAdd < 0) {timeDirectionIndex = 1;}
//if time is reversed, uses second column
weekday[0]=["Sunday","Saturday"][timeDirectionIndex];
weekday[1]=["Monday","Friday"][timeDirectionIndex];
weekday[2]=["Tuesday","Thursday"][timeDirectionIndex];
weekday[3]=["Wednesday","Wednesday"][timeDirectionIndex];
weekday[4]=["Thursday","Tuesday"][timeDirectionIndex];
weekday[5]=["Friday","Monday"][timeDirectionIndex];
weekday[6]=["Saturday","Sunday"][timeDirectionIndex];
//Math.abs makes it always positive; we rely on order of array now
if (daysToAdd < 0) {
   wd=weekday[ ( Math.abs(daysToAdd) +  3 + ( 3 - d.getDay())  )%7 ];
} else {
   wd=weekday[ (Math.abs(daysToAdd) +  (  d.getDay()   ) )%7 ];
}
alert(wd);
