Javascript proxy-pattern problem

Question

I have something like that:

// original function
Foo = function(params) {
 do foo...
}
Foo.prototype.alert = function() {
 alert('foo');
}

Now i want to interfere:

Bar = Foo;
Foo = function(params) {
 do bar...
 return Foo(params);
}

Or the JQuery way:

(function() {
 var proxied = Foo;
 Foo = function() {
 do bar...
 return proxied.apply(this, arguments);
 };
})(); 

The problem now is that Foo is missing all its prototype methods. Any idea how I could make this work?

• nimcap: Isn't it supposed to be return Bar(params); in your code?

Answer 1

jQuery.extend(Foo.prototype, proxied.prototype);

Or even:

Foo.prototype = proxied.prototype;
