我正在尝试编写用于发布用户评论的角码,我想从控制器中将名为帖子的数组推入工厂。我写了一些代码,它似乎不工作。请花些时间在这里纠正我的代码!插入用户输入到角厂
在这里不用我的index.html
<body ng-app="flapperNews" ng-controller="MainCtrl" class="col-sm-4">
<div ng-repeat="post in posts | orderBy:'-upvotes'" class="well ">
<span >
<span ng-click="incrementUpvotes(post)" class="btn btn-primary">+</span>
<span ng-click="decrementUpvotes(post)" class="btn btn-danger">-</span>
{{post.title}} - upvotes: <span class="label label-success">{{post.upvotes}}</span><br>
</span>
</div>
<div>
<div><h3 class="text-warning">Add new Post</h3></div>
<form ng-submit="addPost()">
<input type="text" ng-model="title" class="form-control">
<button type="submit" class="btn btn-success">Post</button>
</form>
</div>
</body>
这里是我的app.js
var app = angular.module('flapperNews', []);
app.factory('newposts',[function(){
var o = {
posts: []
};
return o;
}]);
app.controller('MainCtrl',['newposts',function($scope,newposts){
$scope.posts = newposts.posts;
$scope.addPost = function(){
if(!$scope.title || $scope.title === '') { return; }
$scope.posts.push({title: $scope.title, upvotes: 0});
$scope.title='';
};
$scope.incrementUpvotes = function(post) {
post.upvotes += 1;
};
$scope.decrementUpvotes = function(post) {
post.upvotes -= 1;
};
}]);
,我在控制台得到的错误是
TypeError: Cannot read property 'post' of undefined
at new <anonymous> (app.js:11)
at d (angular.min.js:35)

请详细说明 “似乎并不合作。” – kapa
我已经添加了我在控制台中得到的错误...请检查它 – Sam
“似乎不工作”意味着用户输入不会添加到posts数组。我希望将输入添加到posts数组中,稍后在网页中显示数组元素 – Sam
