Question

我在我的控制器中定义了一个函数，我想在模块中调用它。这怎么可能？

控制器：

var App = angular.module('App',['ngResource','App.filters']);

App.controller('ExerciseCtrl', ['$scope','$http', function($scope, $http) {

    $scope.toggleOn = function (arr, id) {
        // Some code
    }; 

}]);

模块：

angular.module('App.filters', []).filter('someFilter', [function () {
    return function () {
        someArray = [];
        toggleOn(someArray, 1); // Wish to call this function
    };
}]);

我想在模块中调用toggleOn。

Answer 1

脱离我的头顶，也许是这样的：

var App = angular.module('App',['ngResource','App.filters']);

App.service('toggleService', function(){
    var service = {
        toggleOn: function(arr, id){

        }
    };

    return service;
});

App.controller('ExerciseCtrl', ['$scope','$http', 'toggleService', function($scope, $http, toggleService) {

    $scope.toggleOn = toggleService.toggleOn;

}]);

angular.module('App.filters', []).filter('someFilter', ['toggleService', function (toggleService) {
    return function () {
        someArray = [];
        toggleService.toggleOn(someArray, 1); // Wish to call this function
    };
}]);

Answer 2

angular.module('App.filters', []).filter('someFilter', [function () {
    return function (scope) {
        someArray = [];
        scope.toggleOn(someArray, 1); // Wish to call this function
    };
}]);

并将范围传递给过滤器

<span ng-controller="ExerciseCtrl">{{someFilter | this}}</span>

在模块内调用控制器功能
