角服務可以從一個控制器設置的數據而不是其他

Question

我有一個模塊，兩個控制器：

var module = angular.module("app", ["agGrid", "ngAnimate", "ngSanitize", "ngDialog"]) 


module.controller("mainCtrl", ["$scope", "dataService","$timeout","dateFilter","ngDialog", "$http", function ($scope, $http, $timeout, dateFilter, ngDialog, dataService) { 
}]); 


module.controller("modalCtrl", ["$scope", "ngDialog", "dataService", function ($scope, ngDialog, dataService) { 


$scope.printEntity = function() { 
    console.log(dataService.getEntityArray()); 
} 

}]); 

與服務：

module.factory("dataService", function() { 

var entityArrayService = []; 

return { 
    setEntityArray: function (entityArray) { 
     entityArrayService = entityArray; 
    }, 
    getEntityArray: function() { 
     return entityArrayService; 
    } 

}; 

}); 

我可以從我的第二個控制器內部調用dataService.setEntityArray(array) ，但是當我嘗試從我的第一個控制器調用它時，它告訴我dataService.setEntityArray is not a function

Answer 1

依賴性注入的順序不正確。控制器函數中的參數必須重複數組中元素的順序。你的情況dataService是第二個參數：

module.controller("mainCtrl", ["$scope", "dataService","$timeout","dateFilter","ngDialog", "$http", function ($scope, dataService, $timeout, dateFilter, ngDialog, $http) { 
}]); 

Answer 2

你必須在第一控制器定義的變量無效的訂單。它應該是：

function ($scope, dataService, $timeout, dateFilter, ngDialog, $http)
