Javascript：After Effects和Date（）函数返回undefined

Question

情况就是这样。

1. 我的团队制作了一个每周三播放的公告视频。介绍总是相同的，除了日期（文本层为“[Long Month] xx，20xx”）。
2. 我正在尝试编写一些简单的自动化，使日期总是正确的星期三，无论出口日期如何（在星期三强制日期之前，星期三强制日期到 next <之后< / em>星期三）。

我的代码在浏览器中运行，但它在After Effects中不起作用。在AE中，它返回 undefined。帮助！ （运行After Effects 14.2.1.34）

var today, day, date, month

today = new Date(Date(0));
day = today.getDay();
date = today.getDate();
month = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];


function printDate() {
  return month[today.getMonth()] + " " + date + ", " + today.getFullYear();
}


function forceWednesday() {
  if (day === 3) {
    printDate();
  } else if (day < 3) {
    var x = day;
    x = 3 - day;
    return month[today.getMonth()] + " " + (date + x) + ", " + today.getFullYear();
  } else if (day > 3) {
    var dayDiff, dateDiff, nextWed, newDate, wed
    dayDiff = day - 3;
    dateDiff = date - dayDiff;
    nextWed = today.setDate(dateDiff + 7);
    newDate = new Date(nextWed);
    wed = newDate.getDate();
    return month[newDate.getMonth()] + " " + wed + ", " + newDate.getFullYear();
  }
}

forceWednesday();
