如果javascript内置了名称空间，那就更好了，但我发现像Dustin Diaz在这里描述的那样组织东西对我有很大帮助。

var DED = (function() {

    var private_var;

    function private_method()
    {
        // do stuff here
    }

    return {
        method_1 : function()
            {
                // do stuff here
            },
        method_2 : function()
            {
                // do stuff here
            }
    };
})();

我把不同的“名称空间”放在不同的文件中，有时把单独的类放在不同的文件中。通常我从一个文件开始，当类或名称空间变得足够大时，我将它分离到自己的文件中。使用工具将所有文件组合起来进行生产也是一个很好的主意。

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.

代码组织要求采用约定和文档标准: 1. 物理文件的命名空间代码;

Exc = {};

2. 在这些命名空间javascript中分组类; 3.设置原型或相关的函数或类来表示真实世界的对象;

Exc = {};
Exc.ui = {};
Exc.ui.maskedInput = function (mask) {
    this.mask = mask;
    ...
};
Exc.ui.domTips = function (dom, tips) {
    this.dom = gift;
    this.tips = tips;
    ...
};

4. 设置约定以改进代码。例如，将其所有内部函数或方法分组在对象类型的class属性中。

Exc.ui.domTips = function (dom, tips) {
    this.dom = gift;
    this.tips = tips;
    this.internal = {
        widthEstimates: function (tips) {
            ...
        }
        formatTips: function () {
            ...
        }
    };
    ...
};

5. 制作名称空间、类、方法和变量的文档。必要时也讨论一些代码(一些fi和for，它们通常实现代码的重要逻辑)。

/**
  * Namespace <i> Example </i> created to group other namespaces of the "Example".  
  */
Exc = {};
/**
  * Namespace <i> ui </i> created with the aim of grouping namespaces user interface.
  */
Exc.ui = {};

/**
  * Class <i> maskdInput </i> used to add an input HTML formatting capabilities and validation of data and information.
  * @ Param {String} mask - mask validation of input data.
  */
Exc.ui.maskedInput = function (mask) {
    this.mask = mask;
    ...
};

/**
  * Class <i> domTips </i> used to add an HTML element the ability to present tips and information about its function or rule input etc..
  * @ Param {String} id - id of the HTML element.
  * @ Param {String} tips - tips on the element that will appear when the mouse is over the element whose identifier is id <i> </i>.
  */
  Exc.ui.domTips = function (id, tips) {
    this.domID = id;
    this.tips = tips;
    ...
};

这些只是一些技巧，但这对组织代码有很大帮助。记住，你必须自律才能成功!

我为所有我真的不需要在屏幕上实例化几次的东西创建单例，为其他所有东西创建一个类。所有这些都放在同一个文件的同一个名称空间中。所有的东西都是用UML、状态图进行注释和设计的。javascript代码是清楚的html，所以没有内联javascript，我倾向于使用jquery来最小化跨浏览器的问题。

使用继承模式组织大型jQuery应用程序。

对于JavaScript组织一直使用以下

Folder for all your javascript Page level javascript gets its' own file with the same name of the page. ProductDetail.aspx would be ProductDetail.js Inside the javascript folder for library files I have a lib folder Put related library functions in a lib folder that you want to use throughout your application. Ajax is the only javascript that I move outside of the javascript folder and gets it's own folder. Then I add two sub folders client and server Client folder gets all the .js files while server folder gets all the server side files.
