javascript - 验证 JS 中开放时间之间的日期

Question

我想知道验证日期是否在商店正确营业时间内的最佳方法是什么......

我正在为高尔夫专业人士创建一个网站，并接受该网站的类(class)预订。我使用 fullCalendar 作为日历，并将其与谷歌日历集成，这样它就可以轻松同步到专业人士的手机等。

作为日历的一部分，当客户单击时间段时，fullcalendar 会向我提供一个日期对象。我想验证这个选定的时间段是否在商店的营业时间范围内，以便参加类(class)等。

有时会从数据库表中检索时间，但如果效果最好，我可以将它们以 JSON 形式返回到页面上 - 但这不是这个问题的目的......

开放时间根据星期几和“季节”[夏季时间与冬季时间]而有所不同

ie:
 Summer Times
    Monday = 10:00 - 21:00
    Tuesday = 10:00 - 21:00
    Wednesday = 10:00 - 21:00
    Thursday = 10:00 - 21:00
    Friday = 10:00 - 21:00
    Saturday = 08:00 - 18:00
    Sunday = 08:00 - 18:00

 Winter Times
    Monday = CLOSED
    Tuesday = 10:00 - 18:30
    Wednesday = 10:00 - 18:30
    Thursday = 12.00 – 20.30
    Friday = 12.00 – 20.30
    Saturday = 08:00 - 18:00
    Sunday = 08:00 - 18:00

验证这一点的“最佳”方法是什么？

最好的选择是简单地执行嵌套的 if/switch 语句..

[sudo code]
if(summer}
{
    switch(date.getDay())
    {
    case 1:
          if(time > mondayOpeningTime && time < mondayCloseTime)
          {
            return true;
          }
          else
          {
            return false;
          }
      break;
    case 2:
      execute code block 2
      break;
    .....
    default:
      code to be executed if n is different from case 1 and 2
    }
}
else
{
    // Same as summer logic but for winter times etc..
} 

或者有更好的方法吗？

这是我写的。相当粗略，但考虑到了午夜之后关门时间的情况。

    Operating hours check
    =====================================

    - Checks if something is open right now
    - Supports closing times going over midnight
    - Feel free to use in whatever you need :)
    - If you make improvements, please inform me!

    Example:

    // Setting operating hours
    // Key 0 is sunday, 1 is monday and so on
    var hours = [
        // Sunday
        {
            open: '08:00',
            close: '16:00'
        },

        // Monday
        {
            allday: true // Open all day
        },

        // Tuesday
        false, // Closed all day

        // Wednesday
        {
            open: '08:00',
            close: '16:00'
        },

        // Thursday
        {

        {
            open: '08:00',
            close: '16:00'

        // Saturday
        {
            open: '08:00',
