This is getting into dirty territory (or at least I'd feel so) but:
var x = function(){};
var y = function(){ alert(foo); }
x + ;
function () { }
y + ;
function () { alert(foo); }
Best,

x.method2 with a = 1, b = 2.
Can you give a complete example[1] demonstrating the problem?

I have a class
var TObj = Class.create({
initialize: function() {... },
metod1: function() {
this.method2(1,2); --- cal method2 with parameters
},
method2: function(a, b){
var aa = a; -- a b is undefined!
}
});
why in method2
What is the best way to attach one observer to many events
for examle: I need to attach an observer to input element to validate
input value for 'change' and 'paste' events

I need to distinguish between inside the handler-pressed the button is
pressed by user or by code like this: btnclick (btn).
In the event no difference!
