        "_number" : "2013-W45"
    }
}

Day는 여러 작업을 가질 수 있으며 작업은 중첩 될 수 있으며 다른 작업을 여러 개 포함 할 수 있습니다.

이제이 코드를 사용하여

<p ng-repeat="day in myData.Week.Day">
   {{day._dow}} - {{day._templateDay}}
</p>

작동하는 날짜를 나열 할 수 있습니다. 다음 코드로 예상 할 수 있습니다.

<p ng-repeat="day in myData.Week.Day">
    {{day._dow}} - {{day._templateDay}}

    <span ng-repeat="job in day.Job">
        {{job._name}}
    <span/>
</p>

그날의 요일과 최상위 작업을 나열 할 수 있지만 작동하지 않습니다. (중첩 된 작업을 나열하는 것은 지금 그것에 대해 묻지 않고 다음 작업이 될 것입니다).

그렇다면 최소한 최상위 작업을 나열하는 방법은 무엇입니까? 또한 json 형식에서 일부 작업 Objects은 Arrays. 두 상황을 어떻게 처리 할 수 ​​있습니까?

XML에서 변환 된 형식을 직접 사용하는 대신 적절한 JSON 형식을 사용하는 것이 좋습니다.

[
  {
    "number": "2013-W45",
    "days": [
      {
        "dow": "1",
        "templateDay": "Monday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          },
          {
            "name": "work 9-5",

          }
        ]
      },
      {
        "dow": "2",
        "templateDay": "Tuesday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          }
        ]
      }
    ]
  }
]

이것은 일을 훨씬 쉽고 반복하기 쉽게 만듭니다.

Now you can write the loop as -

<div ng-repeat="week in myData">
   <div ng-repeat="day in week.days">
      {{day.dow}} - {{day.templateDay}}
      <b>Jobs:</b><br/> 
       <ul>
         <li ng-repeat="job in day.jobs"> 
           {{job.name}} 
         </li>
       </ul>
   </div>
</div>

If you have a big nested JSON object and using it across several screens, you might face performance issues in page loading. I always go for small individual JSON objects and query the related objects as lazy load only where they are required.

you can achieve it using ng-init

<td class="lectureClass" ng-repeat="s in sessions" ng-init='presenters=getPresenters(s.id)'>
      {{s.name}}
      <div class="presenterClass" ng-repeat="p in presenters">
          {{p.name}}
      </div>
</td> 

The code on the controller side should look like below

$scope.getPresenters = function(id) {
    return SessionPresenters.get({id: id});
};

While the API factory is as follows:

angular.module('tryme3App').factory('SessionPresenters', function ($resource, DateUtils) {

        return $resource('api/session.Presenters/:id', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET', isArray: true
            },
            'update': { method:'PUT' }
        });
    });

Create a dummy tag that is not going to rendered on the page but it will work as holder for ng-repeat:

<dummyTag ng-repeat="featureItem in item.features">{{featureItem.feature}}</br> </dummyTag>
