如何在JavaScript中为命名空间提供实例对象 [英] How to provide namespaces in JavaScript with instanced objects

问题描述

我有一个JavaScript对象"，它是通过以下方式构建的:

I've got a JavaScript "object", built this way:

function foo()
{
    this.length = 0;
}

foo.prototype.getLength = function()
{
    return this.length;
}

...

我知道如何使用单例JavaScript对象模拟名称空间，但是命名"对象(例如上面提到的对象)的最佳方法是什么?

I know how to emulate namespaces with singleton JavaScript objects, but what is the best way to "namepace" an object such as that above that will intanced?

我知道几个JavaScript库都具有命名空间功能，但是我使用的是jQuery，并且宁愿不添加其他库.我希望能够通过使用jQuery为需要实例化的我的JS对象提供内部命名间隔方案来提供自己的名称.

I know that several JavaScript libraries have namepacing capabilities, but I'm using jQuery and would rather not add another library to the mix. I'd like to be able to provide my own, perhaps by exploiting jQuery, intrinsic namespacing scheme for the JS objects of mine that need to be instanced.

谢谢 rp

推荐答案

简单:

if(!MyNamespace) MyNamespace = {};

MyNamespace.foo = function() {
   this.length = 0;
};
MyNamespace.foo.prototype.getLength = function() {
   return this.length;
};
