当我尝试在我正在创建的论坛上保存新主题时,我收到了一个Typeerror:我的控制器
module.controller('newTopicController', ['$scope', '$http', 'dataService', function ($scope, $http, $window, dataService) {
$scope.newTopic = {};
$scope.save = function () {
dataService.addTopic($scope.newTopic)
.then(function () {
$window.location = "/#";
},
function () {
alert("couldnt save topic");
});
};
}]);
我的工厂:
module.factory("dataService", function ($http, $q) {
var _topics = [];
var _isInit = false;
var _isReady = function () {
return _isInit;
};
var _getTopics = function () {
var deferred = $q.defer();
$http.get("/api/topics?withReplies=true")
.then(function (result) {
angular.copy(result.data, _topics);
_isInit = true;
deferred.resolve();
},
function () {
deferred.reject();
});
return deferred.promise;
};
var _addTopic = function (newTopic) {
var deferred = $q.defer();
$http.post("/api/topics", newTopic)
.then(function (result) {
var createdTopic = result.data;
_topics.splice(0, 0, createdTopic);
deferred.resolve(createdTopic);
},
function () {
deferred.reject();
});
return deferred.promise;
};
return {
topics: _topics,
getTopics: _getTopics,
addTopic: _addTopic,
isReady: _isReady
};
});
因此,当我尝试向论坛添加主题时,我只是在控制器中获得“TypeError:无法读取属性'addTopic'的未定义”,就在dataService.addTopic($ scope.newTopic)所在的位置。
我还有另一个也使用工厂的控制器,但这不应该是一个问题吗?
感谢您的时间。
答案 0 :(得分:3)
这似乎不正确:
module.controller('newTopicController', ['$scope', '$http', 'dataService', function ($scope, $http, $window, dataService) {...}
将其更改为:
module.controller('newTopicController', ['$scope', '$http', '$window', 'dataService', function ($scope, $http, $window, dataService) {...}
