Hi,
I have a class ''Menu'' with a method
''addItem''. The method (simplified)
looks like this:
addItem: function(itemId, text)
{
this.container.innerHTML += ''<div
id="''+itemId+''">''+text+''</div>'';
Event.observe(itemId, ''mouseover'',
this.onMouseOverHandler.bindAsEventListener(this), false);
}
I call my class in the following way:
var myMenu = new Menu();
myMenu.addItem(''item1'', ''Item 1'');
myMenu.addItem(''item2'', ''Item 2'');
myMenu.addItem(''item3'', ''Item 3'');
And here comes the mystery: only the last item (item3) triggers the
''onMouseOverHandler'' listener. When I remove item3, than
it''s trigged by
item2 and so on...
Anyone have a solution? Thank you in advance!
Thomas

Try this: Event.observe($(itemId),''mouseover'', this.onMouseOverHandler.bindAsEventListener(this),false); - Joe On 29 Apr 2006 20:59:24 -0000, Thomas Anderson < devlists-scriptaculous-mifkN9UeCURWk0Htik3J/w@public.gmane.org> wrote:> > Hi, > > I have a class ''Menu'' with a method ''addItem''.

Thanks Joe, but $(itemId) behaves the same way as itemId. I''ve solved it by using Insertion.Before instead of direct innerHTML but I still don''t understand what was wrong with my code... Anyone can help me explain it?

Wow, now it''s clear! Thank you a lot!!
