Question

我试图检查今天（0:00）是否在日期数组中，如下所示：

＆＃13;

var today = new Date();
today.setHours(0, 0, 0, 0);
var holidays = [
  new Date(2017, 5, 21, 0, 0, 0).getTime(), // Today
  new Date(2017, 5, 22, 0, 0, 0).getTime(),
  new Date(2017, 5, 23, 0, 0, 0).getTime(),
  new Date(2017, 5, 24, 0, 0, 0).getTime(),
  new Date(2017, 5, 25, 0, 0, 0).getTime()
];
if ($.inArray(today, holidays) > -1) {
  alert('Closed');
} else {
  alert('Open');
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

＆＃13;

但正如你所看到的，它今天没有找到（6月21日），

知道我错过了什么吗？

Answer 1

您正在将日期对象与时间进行比较：

var today = new Date();
today.setHours(0, 0, 0, 0);
var holidays = [
  new Date(2017, 5, 21, 0, 0, 0).getTime(), // Today
  new Date(2017, 5, 22, 0, 0, 0).getTime(),
  new Date(2017, 5, 23, 0, 0, 0).getTime(),
  new Date(2017, 5, 24, 0, 0, 0).getTime(),
  new Date(2017, 5, 25, 0, 0, 0).getTime()
];
if ($.inArray(today.getTime(), holidays) > -1) {
  alert('Closed');
} else {
  alert('Opened');
}

Answer 2

在您的$ .inArray电话中，今天更改＆＃34;＆＃34; to＆＃34; today.getTime（）＆＃34;

Answer 3

today和today.getTime()不同。

＆＃13;

var today = new Date();
today.setHours(0, 0, 0, 0);
today=today.getTime();
var holidays = [
  new Date(2017, 5, 21, 0, 0, 0).getTime(), // Today
  new Date(2017, 5, 22, 0, 0, 0).getTime(),
  new Date(2017, 5, 23, 0, 0, 0).getTime(),
  new Date(2017, 5, 24, 0, 0, 0).getTime(),
  new Date(2017, 5, 25, 0, 0, 0).getTime()
];
if ($.inArray(today, holidays) > -1) {
  alert('Closed');
} else {
  alert('Opened');
}
