javascript - 检查时间是否在2个时间之间

Question

应用程序必须根据当天的当前时间显示门是打开还是关闭的消息。

大门在上午 8:00 至上午 9:30 之前或下午 5:50 后至晚上 9:00 之前开放，其余时间大门保持关闭状态。我想根据输入的时间显示消息。下面的代码输出是意外且不正确的。

function isValid(date, h1, m1, h2, m2) {
        var h = date.getHours();
        var m = date.getMinutes();
        return (h1 < h || h1 == h && m1 <= m) && (h < h2 || h == h2 && m <= m2);
    }


function a() {
        var current = new Date('2020-01-03 09:31:00');
        if ((isValid(current, 8, 0, 9, 30)) || (isValid(current, 5, 50, 21, 0))) {
            return 'Gate is open'
        } else {
            return 'Please come after 8:00am and before 9:30am OR after 5:50pm and before 9:00pm';
        }
}a();

您必须在下午日期中使用 17 而不是 5

function isValid(date, h1, m1, h2, m2) {
  var h = date.getHours();
  var m = date.getMinutes();
  return (h1 <= h && m1 <= m) && (h <= h2 && m <= m2);
}


function a() {
  var current = new Date('2020-01-03 09:31:00');
  if ((isValid(current, 8, 0, 9, 30)) || (isValid(current, 17, 50, 21, 0))){
    return 'Gate is open'
  } else {
    return 'Please come after 8:00am and before 9:30am OR after 5:50pm and before 9:00pm';
  }
}
