Question

我在时区中列出了这个时间段＆＃34; -07：00＆＃34;我想将它们转换为＆＃34; +05：00＆＃34;。

"hours": [
    {
      "from": "11:00",
      "to": "21:00",
      "dayOfWeek": "MONDAY"
    },
    {
      "from": "11:00",
      "to": "21:00",
      "dayOfWeek": "TUESDAY"
    },
    {
      "from": "11:00",
      "to": "21:00",
      "dayOfWeek": "WEDNESDAY"
    },
    {
      "from": "11:00",
      "to": "21:00",
      "dayOfWeek": "THURSDAY"
    },
    {
      "from": "11:00",
      "to": "21:00",
      "dayOfWeek": "FRIDAY"
    }
  ]

如何使用像moment.js这样的库有效地做到这一点？我已经研究过一种方法，但它不符合标准。

function formatDates(hoursList, shopDate, userDate){
    var moment = require('moment');
    var selectedDateText = "";
    var convertedDateList = [];

    for (var x = 0; x < hoursList.length; x++) {
        var fromDate = shopDate.clone();
        var fromMoment = moment(fromDate.format(), "YYYY-MM-DD HH:mm Z");
        var fromTime = fromMoment.utcOffset(userDate.utcOffset());
        fromTime.hours(parseInt(hoursList[x].from.split(":")[0]));
        fromTime.minutes(parseInt(hoursList[x].from.split(":")[1]));
        fromTime.seconds(0);
        fromTime.milliseconds(0);
        console.log(fromTime.format());

        var toDate = shopDate.clone();
        var toMoment = moment(toDate.format(), "YYYY-MM-DD HH:mm Z");
        var toTime = toMoment.utcOffset(userDate.utcOffset());
        toTime.hours(parseInt(hoursList[x].to.split(":")[0]));
        toTime.minutes(parseInt(hoursList[x].to.split(":")[1]));
        toTime.seconds(0);
        toTime.milliseconds(0);
        console.log(toTime.format());

        var initialDay = {
            "from": "",
            "to": "",
            "dayOfWeek": ""
        };
        initialDay.dayOfWeek = fromTime.format("dddd").toUpperCase();
        initialDay.from = fromTime.format("HH:mm");

        if (toTime.format("DDD") != fromTime.format("DDD")) {
            var secondaryDay = {
                "from": "",
                "to": "",
                "dayOfWeek": ""
            };
            initialDay.to = "24:00";

            secondaryDay.dayOfWeek = toTime.format("dddd").toUpperCase();
            secondaryDay.from = "00:00";
            secondaryDay.to = toTime.format("HH:mm");

            convertedDateList.push(secondaryDay);
        } else {
            initialDay.to = toTime.format("HH:mm");
        }

        convertedDateList.push(initialDay);
    }
    console.log(convertedDateList);
    return selectedDateText;
}

主要问题是，转换时的某些时间戳将在2个不同的日期。因此代码中的初始和次要日期。例如：当它大约6个小时被分成两个时，应该在周一晚上9点到12点之间以及周二12点到凌晨3点之间添加。如果它是一个小时数全部为7天且有些日子，转换后的时间从上午12点到凌晨3点到晚上12点甚至有几个小时，这就更难了。

如何妥善解决这个问题？

感谢。

对于时区相关的Moment已经使模块依赖于moment.js - 请找到文档here
