JavaScript implementation of a Proxy class.

proxy.js

/**
 * JavaScript implementation of a Proxy class.
**/
​function Proxy(p_target)
{
	var self = this;
	self.target = p_target;
	
	// Access target's properties
	self.get = function (p_property)
	{
		return self.target[p_property];
	}
	
	self.set = function (p_property, p_value)
	{
		self.target[p_property] = p_value;
	}
	
	// Proxy target's functions
	for (var key in self.target)
	{
		if (typeof self.target[key] === 'function')
		{
			self[key] = function ()
			{
				return self.target[key].apply(self.target, arguments);
			}
		}
	}
}
                
Proxy.prototype = new Object();​

Line 25 needs a closure for private scope, otherwise all the functions are assigned to the latest proxied function.

Here is how I put it together

self[key] = (function (localKey)
{
    return function() { return self.target[localKey].apply(self.target, arguments); };
})(key);

Thanks for sharing your code!
