If you really want to know whether two Date objects represent precisely the same time, or are before/after one another, it's quite easy: just compare the two Dates via the getTime()method, which returns an integer timestamp for the object. For example,
如果您真的想知道两个 Date 对象是否表示完全相同的时间，或者在另一个之前/之后，这很容易：只需通过getTime()方法比较两个 Dates，该方法返回对象的整数时间戳。例如，
var date1 = myDate,
date2 = new Date();
return (date1.getTime() < date2.getTime());
would return true if myDate is before 'now', false if it is now or in the future.
如果 myDate 在 'now' 之前，则返回 true，如果是现在或将来，则返回 false。
