javascript - Uncaught Error : Nothing handled the action 'createTodo'

Question

我正在使用 Ember's Getting Started Guide创建一个 TodoMVC .即使我严格按照说明进行操作，我仍然停留在 creating a new model instance .

当我输入一个新的待办事项并按回车键时，我得到以下控制台输出:

Uncaught Error: Nothing handled the action 'createTodo'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble. ember.min.js:18

我的 js/controllers/todos_controller.js 看起来像这样:

Todos.TodosController = Ember.ArrayController.extend({
  actions: {
    createTodo: function() {
      // Get the todo title set by the "New Todo" text field
      var title = this.get('newTitle');
      if (!title.trim()) { return; }

      // Create the new Todo model
      var todo = this.store.createRecord('todo', {
        title: title,
        isCompleted: false
      });

      // Clear the "New Todo" text field
      this.set('newTitle', '');

      // Save the new model
      todo.save();
    }
  }
});

有什么想法吗？

更新

将我的代码放入 JSFiddle 确实有效:http://jsfiddle.net/narzero/7926x/5/ .我不明白为什么。

我正在使用 Mac OSX 10.9.1。

如果有人还在寻找答案。我遇到了与上述问题相同的问题。

我有由 yeoman 安装的 ember 应用程序。它提供了一个 app.js 文件:

var TodomvcEmber = window.TodomvcEmber = Ember.Application.create();

/* Order and include as you please. */
require('scripts/controllers/*');
require('scripts/store');
require('scripts/models/*');
require('scripts/routes/*');
require('scripts/views/*');
require('scripts/router');

注意到在我的 .tmp/scripts/combined-scripts.js 文件中添加的 Controller 我放在/scripts/controllers/todos_controller.js 中，但没有集成。 在 app.js 文件中，我更改了 require 的顺序(将 Controller 的 require 向下一点)

var TodomvcEmber = window.TodomvcEmber = Ember.Application.create();

/* Order and include as you please. */
require('scripts/store');
require('scripts/models/*');
require('scripts/controllers/*');
require('scripts/routes/*');
require('scripts/views/*');
require('scripts/router');

这对我有用。
