JavaScript 日历操作

Question

我有这样的 Java 代码：

  //first moment of the today
  Calendar cal = new GregorianCalendar();
  cal.set(Calendar.HOUR_OF_DAY, 0);
  cal.set(Calendar.MINUTE, 0);
  cal.set(Calendar.SECOND, 0);
  cal.set(Calendar.MILLISECOND, 0);

  Calendar tomorrow = (Calendar)cal.clone();
  tomorrow.add(Calendar.DAY_OF_YEAR, 1);

  long time = d.getTime();

  // if greater than today's first moment
  if(time >= tomorrow.getTimeInMillis()){
  ...
  }
  ...

如何用 JavaScript 重写它？

Answer 1

var cal = new Date();
cal.setHours(0);
cal.setMinutes(0);
cal.setSeconds(0);
cal.setMilliseconds(0);

var tomorrow = new Date();

tomorrow.setDate(cal.getDate()+1);

我假设 d 是您从其他地方获得的日期对象：

if ( d >= tomorrow ) {

};
