javascript - 如何使用多个日期时间列对 javascript 数组进行排序

Question

给定以下数组:

var effectiveDates= [
    {
        actualDate: "2017-08-29",
        effectiveDate: "2017-01-01",
        time: "13:22"
    },
    {
        actualDate: "2017-08-29",
        effectiveDate: "2017-01-01",
        time: "11:33"
    },
    {
        actualDate: "2017-08-29",
        effectiveDate: "2017-01-01",
        time: "10:57"
    },
    {
        actualDate: "2016-06-17",
        effectiveDate: "2016-01-01",
        time: "10:26"
    },
    {
        actualDate: "2016-06-17",
        effectiveDate: "2016-01-01",
        time: "10:03"
    },
    {
        actualDate: "2015-12-03",
        effectiveDate: "2015-01-01",
        time: "16:54"
    },
    {
        actualDate: "2014-07-07",
        effectiveDate: "2014-05-01",
        time: "10:47"
    },
    {
        actualDate: "2014-07-07",
        effectiveDate: "2014-05-01",
        time: "10:41"
    },
    {
        actualDate: "2014-07-07",
        effectiveDate: "2014-01-01",
        time: "10:36"
    },
    {
        actualDate: "2014-07-07",
        effectiveDate: "2014-01-01",
        time: "10:36"
    }
]

我正在尝试根据 actualDate 或 effectiveDate 降序(或升序，具体取决于顺序)对数据进行排序，然后按时间排序(也基于时间升序或降序所需的顺序)。我遇到的问题是日期顺序正确，但 time 属性顺序不正确。我正在使用 moment.js 进行日期和时间解析。

这是我到目前为止尝试过的:

var desc = true; //false;
effectiveDates.sort(function (a, b) {
            if (desc) {
                if (moment(a.actualDate) === moment(b.actualDate)) {
                    return (moment(b.time) - moment(a.time));
                } else if (moment(a.actualDate) < moment(b.actualDate)) {
                    return 1;
                } else if (moment(a.actualDate) > moment(b.actualDate)) {
                    return -1;
                }
            }
            else {
                if (moment(a.actualDate) === moment(b.actualDate)) {
                    return (moment(b.time) - moment(a.time));
                } else if (moment(a.actualDate) > moment(b.actualDate)) {
                    return 1;
                } else if (moment(a.actualDate) < moment(b.actualDate)) {
                    return -1;
                }
            }
        });

出于某种原因，当按 effectiveDate 升序或降序对数据进行排序时，time 的排序是正确的。但是当按 actualDate 对数据进行排序时，同样是升序或降序，time 数据不正确。

如有任何帮助，我们将不胜感激。

代替

return (moment(b.time) - moment(a.time));

使用:

moment(a.time, "HH:mm") - moment(b.time, "HH:mm")

您需要告诉 moment.js 输入字符串是“时间”字符串。
