如何将使用$ scope的函数包含/注入到angularjs的控制器中？

Question

我正在尝试将工厂中保存的函数库包含在控制器中。

我的 主控制器 如下所示：

recipeApp.controller('recipeController', function ($scope, groceryInterface, ...){

$scope.groceryList = [];
// ...etc...

/* trying to retrieve the functions here */
$scope.groceryFunc = groceryInterface; // would call ng-click="groceryFunc.addToList()" in main view
    /* Also tried this:
    $scope.addToList = groceryInterface.addToList();
    $scope.clearList = groceryInterface.clearList();
    $scope.add = groceryInterface.add();
    $scope.addUp = groceryInterface.addUp(); */
}

然后，在另一个.js文件中，我创建了工厂杂货接口。我已经将此工厂注入到上面的控制器中。

厂

recipeApp.factory('groceryInterface', function(){

        var factory = {};

    factory.addToList = function(recipe){
        $scope.groceryList.push(recipe);
                    ... etc....
    }

    factory.clearList = function() {
            var last = $scope.prevIngredients.pop();
            .... etc...
    }

    factory.add = function() {
    $scope.ingredientsList[0].amount = $scope.ingredientsList[0].amount + 5;
    }

    factory.addUp = function(){
        etc...
    }

    return factory;
});

但是在我的控制台中，我一直在获取ReferenceError: $scope is not defined at Object.factory.addToList，等等。显然，我猜这与$scope我在工厂中的函数中使用的事实有关。我该如何解决？我注意到在我看过的许多其他示例中，没有人$scope在其外部工厂功能中使用过。我曾尝试$scope在工厂中将inject作为参数注入，但这种方法显然行不通。（例如recipeApp.factory('groceryInterface', function(){）

任何帮助，我们都感激不尽！

您的工厂不在$scope同一范围内，因此您无法访问您的。

尝试以下方法：

recipeApp.controller('recipeController', function ($scope, groceryInterface) {

    $scope.addToList = groceryInterface.addToList;
    $scope.clearList = groceryInterface.clearList;
    $scope.add       = groceryInterface.add;
    $scope.addUp     = groceryInterface.addUp;
}

recipeApp.factory('groceryInterface', function () {

    var factory = {};

    factory.addToList = function (recipe) {
        this.groceryList.push(recipe);
    }

    factory.clearList = function() {
        var last = this.prevIngredients.pop();
    }
});

另外，您可以尝试使用一种更加面向对象的方法：

recipeApp.controller('recipeController', function ($scope, groceryInterface) {

    $scope.groceryFunc = new groceryInterface($scope);
}

recipeApp.factory('groceryInterface', function () {

    function Factory ($scope) {

        this.$scope = $scope;
    }

    Factory.prototype.addToList = function (recipe) {
        this.$scope.groceryList.push(recipe);
    }

    Factory.prototype.clearList = function() {
        var last = this.$scope.prevIngredients.pop();
    }

    return Factory;
});
