在 Backbone.js 上在线查找文档真的很容易，但很难找到关于如何在项目中设置 Backbone 并具有良好的类分离的教程或文档。大多数教程只会将所有代码转储到文档就绪函数中......并没有真正投入其中。

我正在尝试遵循此处找到的骨干命名空间模式（使用咖啡脚本而不是香草 js）http://ricostacruz.com/backbone-patterns/#namespace_convention

这是我的基本设置：

索引.html

<!DOCTYPE html>

    <body>

            <!-- SPOTS LIST -->
            <div data-role="page" id="spots">

                <div data-role="header">
                    <h1>Spots</h1>
                    <a href="#search" data-role="button" class="ui-btn-right" data-icon="search" data-corners="false">search</a>
                </div><!-- /header -->

                <div data-role="content">   
                    spots list
                </div><!-- /content -->

                <!-- footer fixed bottom -->
                <div data-role="footer" class="ui-bar" data-position="fixed">
                    <div data-role="navbar">
                        <ul>
                            <li><a href="#home">Home</a></li>
                            <li><a href="#spots">Spots</a></li>
                            <li><a href="#me">Me</a></li>
                            <li><a href="#friends">Friends</a></li>
                        </ul>
                    </div>
                    <!-- /navbar -->
                </div>


            </div><!-- /page -->

                <script type="text/javascript" src="cordova-2.1.0.js"></script>
        <script type="text/javascript" src="js/jquery-1.8.2.js"></script>
                <script type="text/javascript" src="js/jquery.mobile-1.2.0.js"></script>
                <script type="text/javascript" src="js/underscore.js"></script>
                <script type="text/javascript" src="js/backbone.js"></script>

                <!-- backbone -->
                <!-- backbone views -->
                <script type="text/javascript" src="js/app/views/spots_list.js"></script>

                <!-- backbone app js file, not to be confused with phonegap app.whatever -->
                <script type="text/javascript" src="js/app.js"></script>

                <!-- initialize the phonegap app -->
                <script type="text/javascript">
            app.initialize();
        </script>
    </body>
</html>

应用程序.coffee

window.App =
  Models: {}
  Views: {}
  Collections: {}
  Routers: {}
    init: ->
      spotsList = new App.Views.SpotsList()


$ ->
  console.log "init"
  App.init()

spot_index.coffee

class App.Views.SpotsListView extends Backbone.View

  el: $ 'body'

  initialize: ->
    console.log "initialize called"

目录和项目设置如下所示：

文件夹结构图

问题是，当 document ready 触发时，我收到此错误：

Uncaught ReferenceError: App is not defined

也得到这个错误：

Uncaught TypeError: Object #<Object> has no method 'init' app.js:20
(anonymous function) app.js:20
fire jquery-1.8.2.js:974
self.fireWith jquery-1.8.2.js:1082
jQuery.extend.ready jquery-1.8.2.js:406
DOMContentLoaded

（顺便说一句，这个项目是在 Phonegap、coffeescript、backbone.js 和 jQuery Mobile 中完成的）

我引用 ：

        <!-- backbone -->
        <!-- backbone views -->
        <script type="text/javascript" src="js/app/views/spots_list.js"></script>

        <!-- backbone app js file, not to be confused with phonegap app.whatever -->
        <script type="text/javascript" src="js/app.js"></script>

您至少需要在与 App 相关的任何内容之前调用 app.js 脚本，如果您没有先定义对象，则无法调用它。所以对

    <!-- backbone app js file, not to be confused with phonegap app.whatever -->
    <script type="text/javascript" src="js/app.js"></script>

    <!-- backbone -->
    <!-- backbone views -->
    <script type="text/javascript" src="js/app/views/spots_list.js"></script>
