Question

所以我有一系列活动，每个活动都有团队参与。这两个对象是相关的，但都不是另一个的属性。

我想要做的是循环每个事件并显示参与其中的每个团队。我尝试使用嵌套的ng-repeats来做到这一点。我的问题是内部ng-repeats仅在外部ng-repeat完成执行后才会显示。这意味着团队参与最后一次处理的事件将显示在每个表格中。

在我的控制器中，我有一组团队，每当我收到一个新事件时，我都会更新该数组，并且每个都有一个数组

这是我的重复表

<div ng-repeat="event in events" ng-init="getTeams(event.eventId)">
    <div class="active title">Teams in {{event.eventName}} #{{event.eventId}}</div>
          <table>
            <thead>
              <tr> 
                <th>Name</th>
                <th>Sport</th>
                <th>Motto</th>
                <th>W-L-D</th>
                <th>Description</th>
              </tr>
            </thead>
            <tbody>
              <tr ng-repeat="team in teams">
                <td>{{team.teamName}}</td>
                <td>{{team.teamSport}}</td>
                <td>{{team.teamMotto}}</td>
                <td>{{team.win}}- {{team.lose}} - {{team.draw}}</td>
                <td>{{team.teamDescription}}</td>
              </tr>
            </tbody>
          </table>
  </div>

这是我的控制器

(function(){
angular
    .module('foo')
    .controller('EventController', function ($scope, $location, EventService) { 

        $scope.events = [];
        $scope.targetEvent = {};
        $scope.teams = [];

        EventService.getEvents()
        .then(function(events){
            $scope.events = events;
        });

        $scope.getTeams = function(currEventId){
            EventService.getTeams(currEventId)
                .then(function(eventTeams) {
                $scope.teams = eventTeams;
            })
        }
})()

我尝试使用track by但是通过eventId或teamId跟踪它似乎不起作用。提前感谢您的帮助

虽然您每次都创建public class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context .NOTIFICATION_SERVICE); Intent repeatingIntent = new Intent(context,RepeatingActivity.class); repeatingIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(context,100,repeatingIntent, PendingIntent.FLAG_UPDATE_CURRENT); String contentTitle = intent.getStringExtra("contentTitle"); String contentText = intent.getStringExtra("contentText"); NotificationCompat.Builder builder = new NotificationCompat.Builder(context) .setContentIntent(pendingIntent) .setSmallIcon(R.drawable.icon_notification) .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.icon_notification)) .setContentTitle(contentTitle) .setContentText(contentText) .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)) .setVibrate(new long[]{800,500,600,300}) .setLights(Color.GREEN, 500, 500) .setAutoCancel(true); notificationManager.notify(100,builder.build()); // Light up the screen PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE); boolean isScreenOn = false; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) { isScreenOn = pm.isInteractive(); } else if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT_WATCH){ isScreenOn = pm.isScreenOn(); } if(isScreenOn==false) { PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE,"MyLock"); wl.acquire(10000); PowerManager.WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MyCpuLock"); wl_cpu.acquire(10000); } } }变量。根据您当前的实施，它将是全球性的并且对于所有事件都是单一的。我不这么认为你应该在这里使用teams，而是通过循环事件在控制器本身内执行该操作。

ng-init

然后，您只需将内部EventService.getEvents().then(function(events){ $scope.events = events; //loop over each event. events.forEach(function(event){ EventService.getTeams(currEventId) .then(function(eventTeams) { //placed specific teams on event level event.teams = eventTeams; }) }) });更改为下方，然后移除ng-repeat

ng-init

如何在嵌套循环中停止内部ng-repeat，以便在数组更改时更新
