如何实现不显眼的方法转发？
var o = new SomethingComplex;
var o.foo = new SomeThing; // we have o.foo.doSomething
setUpForwarding(o, o.foo);
o.doSomething(); // calls o.doSomething if exist, else o.foo.doSomething
如何设置不显眼的方法转发？使用 ES5 技术是完全没问题的。我可以想象这在 IE6 中是不可能的，
我不是在寻找像 o.call("doSomething"); 这样的方法，我希望它完全不引人注目。
同时编辑 .__proto__ 以便将 o.foo 扔到原型链中是作弊行为，也是不允许的。允许在其自然原型链中使用 o.foo 覆盖 o，但 o 的复杂性不受限制。
还有可行的选择吗？
我只记得 node-proxy 的存在，它允许您扩展 node.js 实现代理（用 C++ 实现）。这提供了包罗万象的功能，并且可以移植到其他 SS JS。
var o = new SomethingComplex;
var o.foo = new SomeThing; // we have o.foo.doSomething
setUpForwarding(o, o.foo);
o.doSomething(); // calls o.doSomething if exist, else o.foo.doSomething
How would one go about setting up unobtrusive method forwarding? Using ES5 techniques is perfectly fine. I can imagine this being impossible in IE6
I'm not looking for a method like o.call("doSomething"); I want it to be completely unobtrusive.
Also editing .__proto__ so you can throw o.foo in the prototype chain is cheating and is disallowed. Overwriting o with o.foo in it's natural prototype chain is allowed but o is not limited in complexity.
Are there any viable options left?
I just remember the existance of node-proxy which allows you to extend node.js to implement proxies (Implemented in C++). This provides catch-all functionality and can probably be ported to other SS JS.

JavaScript 没有“捕获所有”处理程序，尽管正在考虑将其用于未来版本。
您可以通过让
setUpForwarding迭代foo的所有函数成员来解决此特定问题，然后在o中创建具有相同名称的转发函数。但这仅适用于函数。JavaScript does not have 'catch all' handlers, although it is under consideration for a future version.
You could solve this specific issue by having
setUpForwardingiterate through all function member offooand then create a forwarding function inowith the same name. This will only work for functions though.
