Question

我希望当前时间Saturday, October 13, 2018 9:32 PM介于Saturday, October 13, 2018 9:00 PM和Sunday, October 14, 2018 12:00 AM之间，但是js表示不是。知道这怎么可能吗？

var currentTime = moment();
console.log("moment(): ", moment().format('LLLL'))
console.log("currentTime: ", currentTime.format('LLLL'))
var start_time = moment(currentTime.format('YYYY-MM-DD') + ' ' + '21:00:00');
var currentTimePlusDay = currentTime.add(1,'days');
var extra = currentTimePlusDay.format('YYYY-MM-DD') + ' ';
var end_time = moment(extra + '00:00:00');

console.log("start_time: ", start_time.format('LLLL'))
console.log("end_time: ", end_time.format('LLLL'))
var midnight;
console.log("moment(currentTime).isBetween(start_time, end_time): ", moment(currentTime).isBetween(start_time, end_time))

使用时区：America/New_York，输出：

moment():  Saturday, October 13, 2018 9:32 PM
currentTime:  Saturday, October 13, 2018 9:32 PM
start_time:  Saturday, October 13, 2018 9:00 PM
end_time:  Sunday, October 14, 2018 12:00 AM
moment(currentTime).isBetween(start_time, end_time):  false

我在您的作业中将currentTime更改（克隆）为currentTimePlusDay为：

var currentTime = moment();
console.log("moment(): ", moment().format('LLLL'))
console.log("currentTime: ", currentTime.format('LLLL'))
var start_time = moment(currentTime.format('YYYY-MM-DD'));
var currentTimePlusDay = currentTime.clone().add(1,'days');  // <--- THIS
var extra = currentTimePlusDay.format('YYYY-MM-DD') + ' ';
var end_time = moment(extra + '00:00:00');

console.log("start_time: ", start_time.format('LLLL'))
console.log("end_time: ", end_time.format('LLLL'))
console.log("currenttime: ", currentTime.format('LLLL'))
console.log("moment(currentTime).isBetween(start_time, end_time): ", moment(currentTime).isBetween(start_time, end_time))

如果您当天不这样做，那么最终添加的currentTime会发生变化，从而使您的范围介于两者之间。

还更改了开始时间，使其不从21:00:00开始，以确保其有效。但是clone()的变化是不同的。看看是否有帮助。
