Question

我有一组显示的对象，其中包含有关该对象的信息。我使用ng-repeat来显示所有对象，但我现在想要实现一个过滤器或函数，按月分组对象，如果我有同月注册的对象，则在我的索引中显示该月的所有对象

这是我的JSON数组，值“upload_date”是我想获得特定月份的地方

"_embedded": {
    "incidents": [
        {
            "id": 20,
            "name": "Nombre de incidente",
            "description": "Lorem Ipsum is simply dummy text of the printing and typesetting industry.",
            "timestamp": "2015-03-13T00:00:00-0600",
            "upload_date": "2015-03-31T23:58:19-0600",
            "archived": false,
            "_links": {
                "self": {
                    "href": "http://incidents-core/app_dev.php/incidents/20"
                },
                "attachments": {
                    "href": "http://incidents-core/app_dev.php/incidents/20/attachments"
                },
                "comments": {
                    "href": "http://incidents-core/app_dev.php/incidents/20/comments"
                }
            }

这是我的带有ng-repeat的html代码，这可行

<ul class="list" >
               <h1>January</h1><br />**<---- HERE I WOULD LIKE THO SHOW THE MONTH**
               <br />
                <li class="list__item" ng-repeat="incident in incidents">
                    <!-- ngrepeat: mostrar total de incidentes-->
                    <a href="#" data-toggle="modal" data-target="#incidentModal" ng-click="selectIncident($index)">
                        <!-- /.badgetSection-->
                        <figure class="list__item__inner">
                            <div class="bagdets">
                                <span class="glyphicon glyphicon glyphicon-comment"><span> {{incident._embedded.commentsCount}} </span>
                                <span class="glyphicon glyphicon glyphicon-picture"><span> {{incident._embedded.attachmentsCount}} </span>
                            </div>
                            <!-- ./badges -->
                            <div class="incident-image">
                                <img ng-src="{{incident._links.thumbnail.href || 'img/03.jpg'}}">
                                <p class="incident-type"><span>{{incident._embedded.incident_type}}</span>
                                </p>
                            </div>
                            <figcaption>
                                <p>{{incident.name}}</p>
                                <div class="line-separator"></div>
                                <p>{{incident.description | strLimit: 90 }}</p>
                                <div class="line-separator"></div>
                                <p><span class="glyphicon glyphicon-calendar"></span> {{incident.timestamp | date:'EEE - dd/mm/yyyy'}} <span class="glyphicon glyphicon-time"></span> {{incident.timestamp | date:'hh:mm:ss a'}}</p>
                                <div class="line-separator"></div>
                                <p> <span class="glyphicon glyphicon-user"></span> {{incident._embedded.employee}}</p>
                            </figcaption>
                        </figure>
                    </a>
                </li>
            </ul>

我的想法是尝试显示按月排序的所有已注册对象，如果该月没有对象，则不显示月份。但我不知道如何按月分组

What your are looking for is to perform an automatic list divider.
