使用AngularJS和MomentJS每月重复一次

I have a an array with objects looking like this:

我有一个对象像这样的数组:

{
"date":"11/11/2014",
"time":"17.20.37",
"car":"396",
"driver":"Jenny",
"from":"Old Office",
"destination":"Log WH",
"pax":"3","comment":"",
"commenttime":"",
"arrival":"17.20.48",
"inserted":true,
"cancelled":"",
"duration":"00:00:11"
}

What I am trying to accomplish is to automatically list the items by month, like the following:

我要做的是按月自动列出项目，如下所示:

-November 2014

   ng-repeat with records from 11-14

-October 2014

   ng-repeat with records from 10-14

I know this involves going through the array and getting together all items that have a common property (the same month and year).

我知道这包括遍历数组并将所有具有公共属性的项(相同的月份和年份)聚集在一起。

I'm already doing that with the car code, listing the different unique car codes like so:

我已经用汽车代码做过了，列出了不同的独特的汽车代码如下:

var carsDict = {};

angular.forEach($scope.recordlist, function(record) {
  carsDict[record.car] = carsDict[record.car] || [];
  carsDict[record.car].push(record);
});

$scope.carstats = carsDict;

This piece of code creates an array of objects for every unique car code (record.car).

这段代码为每个唯一的car代码(record.car)创建一个对象数组。

I could do the same with the record.date property (which is a moment() object) but it would group together all objects that have the same exact date in common, not the same month and year.

我也可以用这张唱片。date属性(它是一个moment()对象)，但是它会将所有具有相同确切日期的对象组合在一起，而不是相同的月份和年份。

Any idea about how to accomplish this?

你知道怎么做吗?

Here's a JSFiddle of where I got until now. In the example I list the car codes, trips (every object in the array is a trip) and time in the road (sum of all record.duration) for each car.

这是我到现在为止的资料。在这个例子中，我列出了每辆车的车号、行程(数组中的每个对象都是一个行程)和路上的时间(所有记录的总和。持续时间)。

Right now it makes the calculation and shows the results for all the objects of the recordlist, but the next step is to do the same, but by list it automatically by month.

现在，它进行计算并显示记录列表中所有对象的结果，但是下一步也是这样做的，但是按月自动列出。

For each records list you need to create a year-month dictionary (2014-11):

对于每个记录列表，您需要创建一个年度月字典(2014-11):

var monthsDict = {};

angular.forEach(records, function(record) {
  var month = moment(record.date).format('YYYY-MM');
  monthsDict[month] = monthsDict[month] || [];
  monthsDict[month].push(record);
});

You can sort it if you need like so:

如果你需要，你可以这样分类:

var sortDates = function(a,b) { return moment(a.date) - moment(b.date); };

angular.forEach(monthsDict, function(month) {
  month.sort(sortDates);
});
