在Angular工廠的函數中設置一個變量

我有一個Angular工廠生成一個函數，其中一個變量爲下拉列表選擇一個數組。看來我應該從控制器中的用戶選擇中設置該變量。這兩部分工作，但我無法將變量放入控制器的函數中。在Angular工廠的函數中設置一個變量

工廠有幾個數組和一個switch（）函數來選擇一個。工廠返回一個功能。這裏有一些代碼。 ddSelections是一個數組。

languageFactories.factory('changePostDdFactory', ['$translate', function (translate) { 
    return { 
     withLangChoice: function (langKey) { 
      //variables containing arrays and a switch() to select based on langKey 
      return ddSelections; 
     } 
    } 
}]);

用於顯示選定陣列按鈕下拉的HTML是

<div id="postBox" class="floatingSection" data-ng-controller="postButtonController2"> 
    <button id="postButton" dropdown-menu="ddMenuOptions" dropdown-model="ddMenuSelected" class="btn-menu">{{ 'POST' | translate }}</button> 
</div>

該按鈕下拉指令控制器是我在哪裏掙扎。當我硬編碼一些有用的東西，雖然它看起來不像「好的Angular代碼」。當它的變量，我得到各種各樣的問題。我認爲我應該與$範圍合作，但也許這是值得商榷的。 $ scope.getCurrentLanguage似乎是問題所在。這是代碼。

residenceApp.controller('postButtonController2', ['$translate', '$scope', 'changePostDdFactory', 

function ($translate, $scope, ddSelections) { 
    //hardcoded works at page load and shows my intention 
    //$scope.getCurrentLanguage = 'en'; //creates Scope and Model for getCurrentLanguage & ddMenuOptions 
    //$scope.ddMenuOptions = ddSelections.withLangChoice($scope.getCurrentLanguage); //shows correct array from factory 
    //here's my latest of many attempts with a user selected variable that is accessed via the $translate directive 
    //per Batarang there is no Scope and Model for getCurrentLanguage & ddMenuOptions 
    $scope.getCurrentLanguage = function ($translate) { 
     alert('here I am'); //does not fire 
     $translate.use(); //getter per http://stackoverflow.com/questions/20444578/get-current-language-with-angular-translate 
     return $translate.use(); //should return 'en' or 'es' 
    }; 
    $scope.ddMenuOptions = ddSelections.withLangChoice($scope.getCurrentLanguage); //no dropdown, no array change 
    //$scope.ddMenuOptions = ddSelections.withLangChoice(getCurrentLanguage); //page does not load 
    $scope.ddMenuSelected = {}; 
    $scope.$watch('ddMenuSelected', function (newVal) { 
     //if watch() triggers, do something 
    }, true);

也許你需要調用你的函數？
$scope.ddMenuOptions = ddSelections.withLangChoice($scope.getCurrentLanguage($translate));
而不是
$scope.ddMenuOptions = ddSelections.withLangChoice($scope.getCurrentLanguage);

是的，是可以獲得所需的變量在頁面加載出廠功能。出於某種原因，更改語言不適用於這些數組，就像$ translate.use（）;沒有從$ translate中獲得，但也許這是一個不同的問題。 $ translate繼續改變正常的HTML。謝謝，它向前邁進了一步。 – 2014-09-03 15:08:15
