Javascript 安圭拉酒店；承诺

我正在研究angularJS，我需要一些帮助

以下是我想做的：

• 我需要构建一个服务来获取和存储我的应用程序属性（通过$http.get（））
• 我想使用thoses属性有几个弹出窗口（1个弹出窗口=1个指令/控制器..）
• 我不希望弹出窗口“看到”其余调用（myService.myData应该足够了）

我的问题：

• 我无法使服务在控制器调用之前检索数据
• 我想了个办法。。但是它需要一些应用程序更改（在app.js中），我不希望弹出式开发程序这样做
• 由于我不能这样做，我无法在我的服务/控制器中清洁一些东西

我希望客户能够创建自己的弹出窗口，而不必关心服务如何调用应用程序。 我知道我可以通过控制器中的常规回调来完成。。但由于在其中编码是客户机角色，我希望这部分尽可能简单

PS：当然，我以前测试过一个更简单的实现，在控制器内部进行回调等等。。它起作用了。。但我需要像下面一样干净：

代码示例： 服务：

angular.module("myService", []).service("MyService", ['$http', function($http){
    this.propertiesInitialized = false;
        this.availableLanguages = [];
        this.availableResultTypes = [];
        this.availableStates = [];
        this.availableCrawlTypes = [];
        this.dateFormat = "";

        this.getProperties = function(callback)
        {
            $http.get("app/application-properties.json").success(function(JSONProperties) {
                this.availableLanguages = JSONProperties.configurations.crawlerLanguages;
                this.availableResultTypes = JSONProperties.configurations.resultTypes;
                this.availableStates = JSONProperties.configurations.states;
                this.availableCrawlTypes = JSONProperties.configurations.crawlTypes;
                this.dateFormat = JSONProperties.configurations.dateFormat;
                this.propertiesInitialized = true;
            });
        }
    }]);

一个弹出窗口：

angular.module("popup1", ["MyService"])
.controller('Controller1', ['$scope', 'MyService', 
    function($scope, MyService) {

    $scope.languages = MyService.availableLanguages;
    $scope.crawlTypes = MyService.availableLanguagesCrawlTypes;
    $scope.resultTypes = MyService.availableLanguagesResultTypes;

}]);

你有什么想法吗

谢谢大家!
