我只是想從一個工廠是這樣解決的承諾：角JS - 解決承諾在routeProvider
.config(['$routeProvider', '$locationProvider', '$httpProvider', 'SoundRTCProvider', function ($routeProvider, $locationProvider, $httpProvider, SoundRTCProvider) {
$routeProvider
.when('/',{
templateUrl:'views/home/index.html',
controller:'Home',
resolve: {
load: function (configFactory) {
return configFactory.loadAll();
}
}
});
});
則：
.factory('configFactory',['$rootScope', '$q', '$location', '$anchorScroll', '$routeParams', 'ngDialog', 'cacheService', 'sessionFactory', 'geoFactory', 'instrumentsFactory', 'genresFactory', 'langFactory', 'usersFactory', 'contactsFactory', function ($rootScope, $q, $location, $anchorScroll, $routeParams, ngDialog, cacheService, sessionFactory, geoFactory, instrumentsFactory, genresFactory, langFactory, usersFactory, contactsFactory) {

怎麼了，爲什麼我在控制檯中看到錯誤：TypeError：對象不是函數 at initConfig（assets/js/factories.js：35：23）
這意味着第一個return deferred.promise（）;正在產生錯誤，我不明白什麼是錯的，任何幫助appriciated謝謝
天哪權：/感謝隊友要接受在幾分鐘內你的答案 – sbaaaang
@BenjaminGruenbaum只是有時會試着去了解，並非所有的都是天才，有時需要一些小的支持，也如果文件是明確的;） – sbaaaang
另外，你的代碼是_full_延期的反模式和承諾濫用...我沒有downvote這個答案，因爲它是微不足道的。我低估了它，因爲它提供了__bad建議___，如果你遵循它，你將累積技術債務。 –
