Question

所以，我正在关注位于here的Thinkster的Angular教程。我到了你将帖子折射成服务的部分，突然间我的应用程序被破坏了。这是我的代码（app.js）：

var app = angular.module('flapperNews', []);

app.factory('posts', [function(){
  var o = {
    posts: [];
  };
  return o;
}]);
app.controller('MainCtrl', [
'$scope', 'posts',
function($scope,posts){
  $scope.test = 'Hello world!';
  $scope.posts = posts.posts;
  $scope.addPost = function(){
    if(!$scope.title || $scope.title === '') { return; }
    $scope.posts.push({
        title: $scope.title,
        upvotes: 0,
        link: $scope.link
    });
    $scope.title = '';
    $scope.link = '';
  }
  $scope.incrementUpvotes = function(which){
    which.upvotes += 1;
  }
}]);

和HTML（index.html）：

<html>
  <head>
    <title> First Angular App </title>
    <link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js"></script>
    <script src="app.js"></script> <!-- Angular app -->
    <style> .glyphicon-thumbs-up { cursor:pointer } </style>
  </head>
  <body ng-app="flapperNews" ng-controller="MainCtrl">
    <div class="row">
    <div class="col-md-6 col-md-offset-3">

      <div class="page-header">
        <h1>Flapper News</h1>
      </div>

      <div ng-repeat="post in posts | orderBy:'-upvotes'">
        <span class="glyphicon glyphicon-thumbs-up"
          ng-click="incrementUpvotes(post)"></span>
        {{post.upvotes}}
        <span style="font-size:20px; margin-left:10px;">
          <a ng-show="post.link" href="{{post.link}}">
            {{post.title}}
          </a>
          <span ng-hide="post.link">
            {{post.title}}
          </span>
        </span>
      </div>

      <form ng-submit="addPost()"
        style="margin-top:30px;">
        <h3>Add a new post</h3>

        <div class="form-group">
          <input type="text"
            class="form-control"
            placeholder="Title"
            ng-model="title"></input>
        </div>
        <div class="form-group">
          <input type="text"
          class="form-control"
          placeholder="Link"
          ng-model="link"></input>
        </div>
        <button type="submit" class="btn btn-primary">Post</button>
      </form>

    </div>
  </div>
  </body>
</html>

我尝试了很多不同的东西，移动我的帖子等等（上面列出的代码中没有我的帖子;我把它们拿出来）我的臭虫在哪里？

如果它有帮助，以下是代码在浏览器中的显示方式：image

请从posts: [];

中删除;

var app = angular.module('flapperNews', []);

app.factory('posts', [
  function() {
    var o = {
      posts: []
    };
    return o;
  }
]);
app.controller('MainCtrl', ['$scope', 'posts',
  function($scope, posts) {
    $scope.test = 'Hello world!';
    $scope.posts = posts.posts;
    $scope.addPost = function() {
      if (!$scope.title || $scope.title === '') {
        return;
      }
      $scope.posts.push({
        title: $scope.title,
        upvotes: 0,
        link: $scope.link
      });
      $scope.title = '';
      $scope.link = '';
    }
    $scope.incrementUpvotes = function(which) {
      which.upvotes += 1;
    }
  }
]);
