我很惊讶没有人提到MVC框架。我一直在使用Backbone.js来模块化和解耦我的代码，这是非常宝贵的。

有相当多这样的框架，其中大多数也非常小。我个人的观点是，如果您想为华丽的UI编写几行jQuery以外的东西，或者想要一个丰富的Ajax应用程序，那么MVC框架将使您的工作更加轻松。

你的问题是去年年底困扰我的一个问题。区别在于——将代码交给从未听说过私有方法和公共方法的新开发人员。我必须建造一些简单的东西。

最终的结果是一个小框架(大约1KB)，它将对象文字转换为jQuery。语法在视觉上更容易扫描，如果你的js变得非常大，你可以编写可重用的查询来查找使用的选择器、加载的文件、依赖的函数等。

在这里发布一个小框架是不切实际的，所以我写了一篇博客文章和例子(我的第一个。那真是一次冒险!)欢迎您来看看。

对于这里有几分钟时间来查看的其他人，我非常感谢反馈!

推荐使用FireFox，因为它支持对象查询示例的toSource()。

干杯!

遵循良好的OO设计原则和设计模式有助于使代码易于维护和理解。 但我最近发现的最好的东西之一是信号和槽，也就是发布/订阅。 看看http://markdotmeyer.blogspot.com/2008/09/jquery-publish-subscribe.html 简单的jQuery实现。

这个想法在其他语言的GUI开发中也得到了很好的应用。当代码中某个重要的事件发生时，你会发布一个全局合成事件，其他对象中的其他方法可能会订阅该事件。 这提供了很好的对象分离。

我认为Dojo(和Prototype?)有这种技术的内置版本。

参见什么是信号和槽?

以Jquery为中心的命名空间方式组织您的代码可能看起来如下…并且不会与其他Javascript API(如Prototype, Ext)冲突。

<script src="jquery/1.3.2/jquery.js" type="text/javascript"></script>
<script type="text/javascript">

var AcmeJQ = jQuery.noConflict(true);
var Acme = {fn: function(){}};

(function($){

    Acme.sayHi = function()
    {
        console.log('Hello');
    };

    Acme.sayBye = function()
    {
        console.log('Good Bye');
    };
})(AcmeJQ);

// Usage
//          Acme.sayHi();
// or
// <a href="#" onclick="Acme.sayHi();">Say Hello</a>


</script>

希望这能有所帮助。

好的OO + MVC原则对于管理一个复杂的javascript应用程序肯定大有帮助。

基本上，我将我的应用程序和javascript组织成以下熟悉的设计(从我的桌面编程到Web 2.0一直存在)

图像上数值的说明:

Widgets representing the views of my application. This should be extensible and separated out neatly resulting good separation that MVC tries to achieve rather than turning my widget into a spaghetti code (equivalent in web app of putting a large block of Javascript directly in HTML). Each widget communicate via others by listening to the event generated by other widgets thus reducing the strong coupling between widgets that could lead to unmanageable code (remember the day of adding onclick everywhere pointing to a global functions in the script tag? Urgh...) Object models representing the data that I want to populate in the widgets and passing back and forth to the server. By encapsulating the data to its model, the application becomes data format agnostics. For example: while Naturally in Javascript these object models are mostly serialized and deserialized into JSON, if somehow the server is using XML for communication, all I need to change is changing the serialization/deserialization layer and not necessarily needs to change all the widget classes. Controller classes that manage the business logic and communication to the server + occasionally caching layer. This layer control the communication protocol to the server and put the necessary data into the object models Classes are wrapped neatly in their corresponding namespaces. I am sure we all know how nasty global namespace could be in Javascript.

In the past, I would separate the files into its own js and use common practice to create OO principles in Javascript. The problem that I soon found that there are multiple ways to write JS OO and it's not necessarily that all team members have the same approach. As the team got larger (in my case more than 15 people), this gets complicated as there is no standard approach for Object Oriented Javascript. At the same time I don't want to write my own framework and repeat some of the work that I am sure smarter people than I have solved.

jQuery是非常好的Javascript框架，我喜欢它，但随着项目越来越大，我显然需要额外的结构为我的web应用程序，特别是促进标准化OO实践。就我自己而言，经过几次试验，我发现YUI3 Base和Widget (http://yuilibrary.com/yui/docs/widget/和http://yuilibrary.com/yui/docs/base/index.html)基础设施完全满足了我的需要。我使用它们的几个原因。

It provides Namespace support. A real need for OO and neat organization of your code It support notion of classes and objects It gives a standardize means to add instance variables to your class It supports class extension neatly It provides constructor and destructor It provides render and event binding It has base widget framework Each widget now able to communicate to each other using standard event based model Most importantly, it gives all the engineers an OO Standard for Javascript development

与许多观点相反，我不一定要在jQuery和YUI3之间做出选择。这两者可以和平共处。虽然YUI3为我复杂的web应用程序提供了必要的OO模板，但jQuery仍然为我的团队提供了我们都喜欢和熟悉的易于使用的JS抽象。

使用YUI3，我成功地创建了MVC模式，通过分离将Base扩展为模型的类，将Widget扩展为视图的类，当然还有进行必要逻辑和服务器端调用的控制器类。

Widget可以使用基于事件的模型相互通信，并根据预定义的接口侦听事件并执行必要的任务。简单地说，把OO + MVC结构的JS是一个乐趣对我来说。

声明一下，我不是为雅虎工作的!仅仅是一个建筑师在试图解决最初的问题所带来的问题。我认为如果有人找到了等效的OO框架，这也可以。基本上，这个问题也适用于其他技术。感谢所有提出OO原则+ MVC的人，使我们的编程更易于管理。

Dojo从一开始就使用模块系统。事实上，它被认为是Dojo的基石，是将所有Dojo结合在一起的粘合剂:

dojo。要求——官方文件。 理解dojo.declare, dojo。Require和dojo. provider。 引入Dojo。

使用模块Dojo可以实现以下目标:

Namespaces for Dojo code and custom code (dojo.declare()) — do not pollute the global space, coexist with other libraries, and user's non-Dojo-aware code. Loading modules synchronously or asynchronously by name (dojo.require()). Custom builds by analyzing module dependencies to create a single file or a group of interdependent files (so-called layers) to include only what your web application needs. Custom builds can include Dojo modules and customer-supplied modules as well. Transparent CDN-based access to Dojo and user's code. Both AOL and Google carry Dojo in this fashion, but some customers do that for their custom web applications as well.
