javascript - Angular Modal>Ctrl>Service>Ctrl 继承不起作用

Question

我正在尝试将模型链接到服务，这将使我能够在整个应用程序中更新全局模型，但它似乎没有按预期工作。

我最近开始研究 AngularJS，所以我可能误解了我的代码，但是根据我的理解，服务将作为实例工作，而不是工厂单例，工厂单例应该允许我使用服务来控制所有 $scoped模型。

我正在尝试像这样链接我的模型:

模型: {{ language.title }}

>>> ctrl1: $scope.language = langSrvic.store;

>>> srvic: langSrvic.store = myFactory;

>>> ctrl2: langSrvic.set('locale', 'fr');

>>> 语言实例存储已更新(应反射(reflect) Controller 1 模型中的更改)

//Application
var app = angular.module('app',[]);

//Controller 1
app.controller('first', ['$scope', 'language', function($scope, language){
	$scope.language = language.store;
    setTimeout(function(){
        console.log($scope.language.title); //My application
        console.log(language.store.title); //Something something french
    }, 1500);
}]);

//Language service
app.service('language', ['i18n', function(i18n){
	return {
		locale: 'en',
		store: i18n['en'],
		set: function(prop, val){
			this[prop] = val;
			this.store = i18n[this.locale];
		}
	}
}]);

//Factory - storing instead of an api temporarily
app.factory('i18n', [function(){
	return {
		en:{
			title: 'My application'
		},
		fr:{
			title: 'Something something french'
		},
	}
}]);

//Controller 2 - changing locale to fr which should update the instance store and so update the first scope
app.controller('second', ['$scope', 'language', function($scope, language){
    language.set('locale', 'fr');
    $scope.language = language.store;
}]);

<div ng-controller="first">
    {{ language.title }}
    <div ng-controller="second">
        {{ language.title }}
    </div>
</div>

您正在引用不同的store对象:

set: function(prop, val){
    this[prop] = val;
    this.store = i18n[this.locale]; // this line sets language.store to the new object but Controller 1 is referencing the old one
}
