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。

您没有提到服务器端语言是什么。或者，更确切地说，您在服务器端使用什么框架(如果有的话)。

IME，我在服务器端组织东西，让它全部震动到网页上。该框架的任务不仅是组织每个页面必须加载的JS，还包括与生成的标记一起工作的JS片段。这样的片段通常不希望发出超过一次——这就是为什么它们被抽象到框架中，以便代码处理该问题。: -)

对于必须发出自己的JS的最终页面，我通常发现生成的标记中有一个逻辑结构。这种本地化的JS通常可以在这种结构的开始和/或结束处组装。

请注意，这些都不能免除您编写高效JavaScript的责任!: -)

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。

"Write like crazy and just hope it works out for the best?", I've seen a project like this which was developed and maintained by just 2 developers, a huge application with lots of javascript code. On top of that there were different shortcuts for every possible jquery function you can think of. I suggested they organize the code as plugins, as that is the jquery equivalent of class, module, namespace... and the whole universe. But things got much worse, now they started writing plugins replacing every combination of 3 lines of code used in the project. Personaly I think jQuery is the devil and it shouldn't be used on projects with lots of javascript because it encourages you to be lazy and not think of organizing code in any way. I'd rather read 100 lines of javascript than one line with 40 chained jQuery functions (I'm not kidding). Contrary to popular belief it's very easy to organize javascript code in equivalents to namespaces and classes. That's what YUI and Dojo do. You can easily roll your own if you like. I find YUI's approach much better and efficient. But you usualy need a nice editor with support for snippets to compensate for YUI naming conventions if you want to write anything useful.

在我之前的工作中，我成功地将Javascript模块模式应用到Ext JS应用程序中。它提供了一种创建良好封装代码的简单方法。

我认为这可能与DDD(领域驱动设计)有关。我正在开发的应用程序，虽然缺乏正式的API，但确实通过服务器端代码(类/文件名等)给出了提示。有了这些，我创建了一个顶级对象作为整个问题域的容器;然后，我在需要的地方添加名称空间:

var App;
(function()
{
    App = new Domain( 'test' );

    function Domain( id )
    {
        this.id = id;
        this.echo = function echo( s )
        {
            alert( s );
        }
        return this;
    }
})();

// separate file
(function(Domain)
{
    Domain.Console = new Console();

    function Console()
    {
        this.Log = function Log( s )
        {
            console.log( s );
        }
        return this;
    }
})(App);

// implementation
App.Console.Log('foo');
