Javascript - 对包含根据日期升序和降序的对象的嵌套数组进行排序

Below is my json data:

以下是我的json数据：

var homes={
"ERROR": "SUCCESS",
"DATA": [
    {
        "BookingID": "9513",
        "DutyStart": "2016-02-11 12:00:00"
    },
    {
        "BookingID": "91157307",
        "DutyStart": "2016-02-11 13:00:00"
    },
    {
        "BookingID": "95117317",
        "DutyStart": "2016-02-11 13:30:00"
    },
    {
        "BookingID": "957266",
        "DutyStart": "2016-02-12 19:15:00"
    },
    {
        "BookingID": "74",
        "DutyStart": "2016-02-11 12:21:00"
    }
]
};

I want to sort the array according to DutyStart(in date format) in Descending and Ascending order using Javascript only and append the data to body or alert the sorted array.

我想根据DutyStart（日期格式）使用Javascript按降序和升序排序数组，并将数据附加到正文或警告已排序的数组。

I tried the solution fromThis question but iam not able to get it.

我试过这个问题的解决方案，但我无法得到它。

Thanks in advance.

提前致谢。

You can sort very easily on ISO 8601-like date strings since they work as strings as well as numbers would.

您可以非常轻松地对类似ISO 8601的日期字符串进行排序，因为它们可以像字符串一样工作。

Pass the values to a sort function and return 0, 1 or -1 depending the comparison, e.g.

将值传递给sort函数并根据比较返回0,1或-1，例如：

// Data
var homes={
"ERROR": "SUCCESS",
"DATA": [
    {
        "BookingID": "9513",
        "DutyStart": "2016-02-11 12:00:00"
    },
    {
        "BookingID": "91157307",
        "DutyStart": "2016-02-11 13:00:00"
    },
    {
        "BookingID": "95117317",
        "DutyStart": "2016-02-11 13:30:00"
    },
    {
        "BookingID": "957266",
        "DutyStart": "2016-02-12 19:15:00"
    },
    {
        "BookingID": "74",
        "DutyStart": "2016-02-11 12:21:00"
    }
]
};

// Sort - operates on the original array
homes.DATA.sort(function(a, b) {
  return a.DutyStart < b.DutyStart? -1 : (a.DutyStart == b.DutyStart? 0 : 1); 
});

document.write(JSON.stringify(homes.DATA));

Simple bubble sort for your data, sorting by the date:

您的数据的简单冒泡排序，按日期排序：

var homes={
"ERROR": "SUCCESS",
"DATA": [
    {
        "BookingID": "9513",
        "DutyStart": "2016-02-11 12:00:00"
    },
    {
        "BookingID": "91157307",
        "DutyStart": "2016-02-11 13:00:00"
    },
    {
        "BookingID": "95117317",
        "DutyStart": "2016-02-11 13:30:00"
    },
    {
        "BookingID": "957266",
        "DutyStart": "2016-02-12 19:15:00"
    },
    {
        "BookingID": "74",
        "DutyStart": "2016-02-11 12:21:00"
    }
]
};


var list = homes.DATA.sort(function(a, b) {
    return a.DutyStart - b.DutyStart;
});
console.log(list);

Hope this helps.

希望这可以帮助。

I suggest to use String#localeCompare for this task, because it compares strings and while the data are ISO 8601 date strings, they can be sorted directly with this method.

我建议使用String＃localeCompare来完成此任务，因为它比较字符串，而数据是ISO 8601日期字符串，可以使用此方法直接对它们进行排序。

var homes = { "ERROR": "SUCCESS", "DATA": [{ "BookingID": "9513", "DutyStart": "2016-02-11 12:00:00" }, { "BookingID": "91157307", "DutyStart": "2016-02-11 13:00:00" }, { "BookingID": "95117317", "DutyStart": "2016-02-11 13:30:00" }, { "BookingID": "957266", "DutyStart": "2016-02-12 19:15:00" }, { "BookingID": "74", "DutyStart": "2016-02-11 12:21:00" }] };

homes.DATA.sort(function (a, b) {
    return a.DutyStart.localeCompare(b.DutyStart);
});

document.write('<pre>' + JSON.stringify(homes, 0, 4) + '</pre>');
