Question

我正在按照教程创建一个hackernews / reddit克隆，但由于某种原因，应用程序无法正常工作。

在我的浏览器控制台中，我收到以下错误：

UILabel

这里发生了什么？对不起，我不熟悉这个问题。

我在app.js

Uncaught SyntaxError: Unexpected token .               app.js:46 
Uncaught Error: [$injector:modulerr]                   angular.js:3857 http://errors.angularjs.org/1.2.19/$injector/modulerr?p0=flapperNews&p1=Err…gleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.2.19%2Fangular.min.js%3A18%3A139)

index.html看起来像这样：

angular.module('flapperNews', ['ui.router'])
.config([
'$stateProvider',
'$urlRouterProvider',
function($stateProvider, $urlRouterProvider) {

  $stateProvider
    .state('home', {
      url: '/home',
      templateUrl: '/home.html',
      controller: 'MainCtrl'
    })
    .state('posts', {
      url: '/posts/{id}',
      templateUrl: '/posts.html',
      controller: 'PostsCtrl'
    })

  $urlRouterProvider.otherwise('home');
}])
.factory('posts', [function(){
  var o = {
    posts: []
  };
  return o;
}])
.controller('MainCtrl', [
'$scope',
'posts',
function($scope, posts){
  $scope.posts = posts.posts;
  $scope.incrementUpvotes = function(post){
    post.upvotes += 1;
  }
  $scope.addPost = function(){
    if(!$scope.title || $scope.title === '') { return; }
    $scope.posts.push({
      title: $scope.title, 
      link: $scope.link,
      upvotes: 0
    });
    $scope.title = '';
    $scope.link = '';
  };
}]);
.controller('PostsCtrl', [
'$scope',
'$stateParams',
'$posts',
function($scope, $stateParams, posts) {
  $scope.posts.push({
    titile: $scope.title,
    link: $scope.link,
    upvotes: 0,
    comments: [
      {author: 'Joe', body: 'Cool post!', upvotes: 0},
      {author: 'Bob', body: 'Great idea but everything is wrong!', upvotes: 0}
    ]
  });
  $scope.post = posts.posts[$stateParams.id];
}]);

当我删除;从第46行我在控制台中得到以下奇怪的东西。它似乎陷入了一个带有连续错误信息的循环中。

Answer 1

删除;控制器定义正上方的PostsCtrl：

}]) //here
.controller('PostsCtrl'

;正在干扰控制器的链接。

尝试在服务器，IIS或Apache下打开您的应用程序，不要只在浏览器中打开index.html
