[英]AngularJS : Using factory inside a controller
This is my first attempt to use the Angularjs and I'm trying to create a service and use it inside a controller: 这是我第一次尝试使用Angularjs,我正在尝试创建一个服务并在控制器中使用它:
var appTest = angular.module("appTest", ["ngRoute"]);
var appTestControllers = angular.module('appTestControllers', []);
appTest.config(['$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/home.html',
controller: 'HomeCtrl'
});
$locationProvider.html5Mode(false);
}
]);
appTest.factory("booksApi", function($http){
var _getBooks = function() {
return $http.get('http://localhost/editora-voo/website/books.json');
};
return{
getBooks: _getBooks
};
});
appTest.controller('HomeCtrl', ['$scope', '$http', function($scope, $http, booksApi) {
booksApi.getBooks().success(function(data) {
$scope.books = data;
});
}]);
But it is returning an error: Cannot read property 'getBooks' of undefined 但它返回一个错误:无法读取未定义的属性'getBooks'
You missed to add booksApi
depnedency inside your controller dependency array, You should add it first and then use that inside the function of controller. 您错过了在控制器依赖项数组中添加booksApi
depnedency,您应该先添加它然后在控制器的函数内使用它。
Controller 调节器
appTest.controller('HomeCtrl', ['$scope', '$http', 'booksApi', //<--missed dependency here
function($scope, $http, booksApi) {
booksApi.getBooks().then(function(response) {
$scope.books = response.data;
});
}]);
