如何使今天的日期等于特定日期?

How do I make today's date equal to a specific date?

  const today = new Date();
  today.setHours(0,0,0,0); // Tue May 31 2022
 
  let dateHoliday = new Date('Tue May 31 2022');
  (today == dateHoliday) ? alert('holiday') : alert('regular day');

上面的代码 returns 正常的一天。我希望它是真的。

您可以对两个值调用 .getTime(),然后对数值进行比较。

const today = new Date();
today.setHours(0,0,0,0); // Tue May 31 2022
 
let dateHoliday = new Date('Tue May 31 2022');
(today.getTime() === dateHoliday.getTime()) ? alert('holiday') : alert('regular day');
