Question

我正在尝试运行一个脚本，该脚本根据预定的日期数组（公共假日）检查今天的日期。但是，我正在努力了解阵列设置。我已经使用单个日期在没有数组的情况下运行了脚本，但是没有获得如何将其转换为具有多个选项进行检查的数组的方法。

下面写的代码；

var today = new Date().getHours();
var daycheck = new Date().getDay();
var holidayArray = new Date('12/19/2019');
var todayDate = new Date();

if (holidayArray.setHours(0, 0, 0, 0) == todayDate.setHours(0, 0, 0, 0)) {
  alert('This is outside of business hours (Public Holiday).');
  window.history.back();
} else {
  if (today <= 8 || today >= 17) {
    alert('This is outside of business hours. General access is provided from 9am - 5pm Monday to Friday');
    window.history.back();
  }
  else {
    if (daycheck == 0 || daycheck == 6) {
      alert('This is outside of business hours(weekend).');
      window.history.back();
    }
    else {
      if (confirm('It is currently within business hours during the week. You can now continue.')) {
        window.location.href = "https://URL";
      }
      else { window.history.back() }
    }
  }
}

在向holidayArray变量添加其他日期方面，我需要帮助，因为每次尝试进行操作都无法正常工作。

预先感谢

Answer 1

在JavaScript中，您可以通过以下语法创建数组：var holidayArray = [new Date("12/19/2019"), new Date("12/20/2019"), new Date("12/21/2019")]

然后您必须遍历此数组，例如：

for (let holiday of holidayArray) {
    // Place your IF statements in here and make your checks against the value "holiday". For example:

    if (holiday.setHours(0,0,0,0) == todayDate.setHours(0,0,0,0)) {
        alert("This is outside of business hours (Public Holiday).");
        window.history.back();
    }

}

这将依次遍历您的数组。 holiday将代表数组中的每个值。

Array.some（）是您需要的：

将上面的代码放入checkDate函数中，然后复制下面的示例

function checkDate(d){
    return d.setHours(0, 0, 0, 0) == todayDate.setHours(0, 0, 0, 0))
}
let isHoliday = holidayArray.some(checkDate);

还需要将holidayArray设置为Dates的数组，而不是Date

检查今天是否在日期数组中
