控制器類
eventsApp.controller('EventController',
function EventController ($scope, eventData) {
$scope.sortorder = 'name';
$scope.event = eventData.getEvent();
$scope.upVoteSession= function (session) {
session.upVoteCount++;
};
$scope.downVoteSession = function (session) {
session.upVoteCount--;
};
}
);
===============================
服務類
eventsApp.factory('eventData', function ($resource, $q) {
var resource = $resource('/data/event/:id', {id:'@id'});
return{
getEvent : function() {
var deferred = $q.defer();
resource.get({id:1},
function (event) {
deferred.resolve(event);
},
function (response) {
deferred.reject(response);
});
return deferred.promise;
},
save: function (argument) {
// body...
var deferred = $q.defer();
event.id=5;
resource.save(event,
function function_name (response) { deferred.resolve(response); },
function function_name (response) { deferred.reject(response); }

我在這裏面臨的問題是，Angular的最新版本不允許實現承諾，因爲它之前使用過。在文件中，他們說，要實現承諾，你必須對承諾範圍作出承諾。 $ scope.apply（）;
隨着$資源只有我得到我的模板更新，但$資源和$ Q承諾模板空
我的問題在這裏，如何控制和服務中管理範圍，如果我們需要在兩個層面上管理範圍，那麼服務的好處是什麼？任何人都可以幫我解釋一下，如何使用最佳實踐或質量代碼實現這一目標？
我面對的問題是，標記的對象沒有獲得價值並且代表null，如下圖所示。
謝謝。默認情況下
eventData.getEvent().then(function(res){
$scope.event = res;
});
