我尝试在表中包含新条目后立即更新列表。
已尝试使用$ interval服务,但在回调之后未加载控制器。

$scope.displayNotification=function(){
           NavbarService.displayNotification()
           .then(function(response){
               angular.forEach(response,function(val,key){
                   if(key == 'success'){
                       $scope.notificationList= val;
                       alert("Hi");
                       console.log($scope.notificationList);
                       if(null != $scope.notificationList && undefined !=$scope.notificationList){
                           $scope.notificationCount = $scope.notificationList.length;
                       }
                   }
               });
           },function(){
              // console.error("Error while fetching Notification");
           });
       }


使用此函数在间隔后回调函数

intervalPromise = $interval($scope.displayNotification, 3000);


调用此函数从我的表中获取数据。

这是http通话

function displayNotification() {
            var defer = $q.defer();
            var url='api/notify';
            $http({
                method : "POST",
                url : url,
                data :  {}
            }).success( function(response, status,config, headers) {
                defer.resolve(response);
            }).error(function(errResp) {
                defer.reject({ message:"No Notification Details" });
            });

    return defer.promise;
        }

最佳答案

**更新了封装的答案(安全应用)**
尝试使用此安全应用技巧:

$scope.safeApply = function(fn) {
  var phase = this.$root.$$phase;
  if(phase == '$apply' || phase == '$digest') {
    if(fn && (typeof(fn) === 'function')) {
      fn();
    }
  } else {
    this.$apply(fn);
  }
};

尝试这样称呼它:
$scope.safeApply(function() {
    $scope.notificationCount = $scope.notificationList.length;
});

或像这样:
$scope.notificationCount = $scope.notificationList.length;
$scope.safeApply();
