Hi!
Could anyone why this line:
this.intercambiador.observe(''click'',
NodoYanged.intercambiar.bindAsEventListener(NodoYanged));
raises NodoYanged.intercambiar has no properties?
Here the complete code:
var NodoYanged = Class.create({
initialize: function(objeto) {
this.objeto = $$(objeto).first();
this.intercambiador =
this.objeto.select(''.Intercambiador'').first();
this.intercambiador.observe(''click'',
NodoYanged.intercambiar.bindAsEventListener(NodoYanged));
},
intercambiar: function(evento)
{
alert(this);
},
});
Thanks!

I don''t mean to be flippant (too much), but it''s likely that
NodoYanged.intercambiar doesn''t have any properties. In other words,
this expression likely isn''t returning anything:
this.objeto.select(''.Intercambiador'').first();
Is it a problem with case-sensitivity of your CSS class?

Hi Tom!
I check this.objeto.select(''.Intercambiador'').first() and is
correct
(is the expected DOM object)
NodoYanged.intercambiar as you could see is a method of the class
NodoYanged
Any idea?

NodoYanged is the class, not an object. You need to instantiate an object and bind its method to the object. If you don''t understand the distinction between classes and their instances, you need to go read up on it. --Greg On Wed, Oct 31, 2007 at 12:42:03PM -0600, Tom Gregory wrote:> I don''t mean to be flippant (too much), but it''s likely that > NodoYanged.intercambiar doesn''t have any properties.

Yeah, it works with this Sorry, Greg, but the example isn''t about a class and this is my very fist one javascript object (but not my first object, I''m a Zoper) thanks a lot!

Doesn''t matter, Greg! I''m from Barcelona (Spain) and my english is so rudimentary that sometimes I don''t understand the correct tone of the responses :D I point the example with the hope the writer reads this and put another one with a class too Glad to be helped by you!
