Is there a reliable way of getting the instance of a JavaScript object?

For example, relying on the fake \'obj.getInstance()\' function.

var

    You can do :

        get(){ // Method
            for ( var nameOfVariable in window ) 
                if (eval(nameOfVariable +"=== this")) return nameOfVariable;// true if variable name is instace of this
            return "";            
        }
