angularjs – AngularUI日历事件源,在每个视图开关上调用一个函

为了证明这个问题,我将解释我想要实现的目标.我正在使用AngularUI日历创建一个预订系统,问题是当事件数量增加时(100个事件,日历将需要几分钟来绑定数据),日历的性能开始迅速下降.由于我每次用户更改视图(周,月,日,上一个,下一个等等)时都会通过发送 AJAX请求来尝试从后端获取数据,这是我开始时有问题.

正如在AngularUI Calendar网站上建议的那样,我可以使用这个函数：$scope.eventsF = function(start,end,timezone,callback){…}并将它添加到$scope.eventSources中,它将在每个上面调用查看开关.我将$scope.eventsF添加到我的$scope.eventSources,但它从未更新过.

这是示例(获取所有数据,并且它正在工作)：

$scope.mainEvents = []; //To initiate the event source
Event.getEvents().then(function (events) { // Event is a factory
  if (events) { //Checking if I have events
    // If I try: $scope.mainEvents = events; the $scope.eventSources won't update
    angular.forEach(events,function(value) {
      this.push(value);
    },$scope.mainEvents);
  } else {
    // Tell the user no events to render...
  }
},function (error) {
  console.log(error);
});

$scope.eventSources = [$scope.mainEvents,$scope.draftEvents];

现在我更改了Event.getEvents()以获取两个参数作为视图的开始日期和结束日期,将它们发送到后端,并再次以json的形式检索数据(工作正常,我安慰了它).

这是代码(我尝试了两种方式)：事件正在渲染,但$scope.eventSources并未在这两种方式中进行更新.

第一：

$scope.mainEvents = function (start,callback) {
  var s = start.format('YYYY-MM-DD'),e = end.format('YYYY-MM-DD');
  Event.getEvents(s,e).then(function (events) {
    $scope.mainEvents = []; //even tried $scope.eventSources.mainEvents
    if (events) {
      angular.forEach(events,function (value) {
        this.push(value);
      },$scope.mainEvents); //event tried $scope.eventSources.mainEvents
      callback($scope.mainEvents);
    }
  },function (error) {
    console.log(error);
  });
};

$scope.eventSources = [$scope.mainEvents,$scope.draftEvents];

第二：

$scope.eventsF = function (start,e).then(function (events) {
    $scope.mainEvents = [];
    if (events) {
      angular.forEach(events,$scope.mainEvents);
      callback($scope.mainEvents);
    }
  },$scope.draftEvents,$scope.eventsF];

我希望这很清楚.

$scope.mainEvents = [];
$scope.draftEvents = [];
$scope.eventsF = function (start,callback) {
    var s = start.format('YYYY-MM-DD'),e = end.format('YYYY-MM-DD');
    Event.getEvents(s,e).then(function (events) {
        $scope.mainEvents = [];
        if (events) {
            angular.forEach(events,function (value) {
                this.push(value);
            },$scope.mainEvents);
            // Re-assign event sources
            $scope.eventSources = [$scope.mainEvents,$scope.eventsF];
            // Assume that 'events' is an array with 5 elements.
            // console.log($scope.eventSources) will produce :
            // Array [ Array[5],Array[0],app</$scope.eventsF() ]

            callback($scope.mainEvents);
        }
    },function (error) {
        console.log(error);
    });
};
$scope.eventSources = [$scope.mainEvents,$scope.eventsF];
// console.log($scope.eventSources) will produce :
// Array [ Array[0],app</$scope.eventsF() ]
