我是 MEAN Stack 开发的初学者。我试图玩一些 Angular 东西，但 Controller 完全搞乱了。 这是我的主要 html 文件
<!--main.html-->
<html>
<head>
<title>Chirp</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<script src="javascripts/chirpApp.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<link rel="stylesheet" href="stylesheets/style.css">
</head>
<body ng-app="chirpApp">
<div id='main' class="container" ng-controller="mainController">
<div class="col-md-offset-2 col-md-8">
<div class="clearfix">
<form ng-Submit="post()">
<input required type="text" class="form-control" placeholder="Your name" ng-model="newPost.created_by" />
<textarea required class="form-control" maxlength="200" rows="3" placeholder="Say something" ng-model="newPost.text"></textarea>
<input class="btn submit-btn pull-right" type="submit" value="Chirp!" />
</form>
<div id="post-stream">
<h4>Chirp Feed</h4>
<div class="post" ng-repeat="post in posts | orderBy:'created_at':true" ng-class-odd="'odd'" ng-class-even="'even'">
<p>{{post.text}}</p>
<small>Posted by @{{post.created_by}}</small>
<small class="pull-right">{{post.created_at | date:"h:mma 'on' MMM d, y"}}</small>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
我已经创建了另一个用于注册的 html 文件。这是它的代码。
<!--register.html-->
<html>
<head>
<title>Chirp</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<script src="javascripts/chirpApp.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<link rel="stylesheet" href="stylesheets/style.css">
</head>
<body ng-app="chirpApp">
<div id='main' class="container" ng-controller="authController">
<form class="form-auth" ng-submit="register()">
<h2>Register</h2>
<p class="text-warning">{{error_message}}</p>
<input type="username" ng-model="user.username" placeholder="Username" class="form-control"><br>
<input type="password" ng-model="user.password" placeholder="Password" class="form-control"><br>
<input type="submit" value="Register" class="btn btn-primary" />
</form>
</div>
</body>
</html>
我创建了两个单独的 Controller 用于注册和发帖。第一个 Controller 运行良好，但每当我尝试添加第二个 Controller 时，我都会收到一条错误消息。这是我的 Controller 的代码。
//chirpApp.js
var app = angular.module('chirpApp', []);
app.controller('mainController', function($scope){
$scope.posts = [];
$scope.newPost = {created_by: '', text: '', created_at: ''};
$scope.post = function(){
$scope.newPost.created_at = Date.now();
$scope.posts.push($scope.newPost);
$scope.newPost = {created_by: '', text: '', created_at: ''};
};
});
app.controller('authController', function($scope){
$scope.user = {username: '', password: ''};
$scope.error_message = '';
$scope.login = function(){
//placeholder until authentication is implemented
$scope.error_message = 'login request for ' + $scope.user.username;
};
$scope.register = function(){
//placeholder until authentication is implemented
$scope.error_message = 'registeration request for ' + $scope.user.username;
};
});
我在 Chrome 控制台中收到以下错误:

main.html 工作正常，数据绑定(bind)成功。 问题出在 register.html 页面上。我想 authController 没有被绑定(bind)
有人可以建议我实现相同方法的最佳方法吗？为什么 Controller 变得未定义？
最佳答案
尝试以下 list :
- AngularJS 库包含在 中
- ng-app=".."指令位于index.html
- ..path/to/module 和index.html 中的其他 Controller
- 正确定义模块和 Controller (拼写、语法等)
Controller 示例(如果不使用全局 Angular 变量:
app.controller('AppController', ['$http', '$scope', '$log',
function($http, $scope, $log) {
// TODO: implement
}
]);
希望这有帮助。
关于javascript - Controller 不是函数得到未定义的错误消息 Angular js，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29980190/
