[jQuery] callback

[jQuery] callback


Hi,
I am welcoming myself to Jquery, and I am glad that I give myself a
chance to try jquery. The documentation and tutorials which many seems
to ignore is one of the things that makes me to go for jquery for my
javascript & ajax need.
Upon finishing the How jQuery Works, I want to learn why callback
should be executed after the parent. As a newbie to javascript/jQuery,
I am expecting that the callback should be executed first before the
parent. What is the reason or logic behind, and should this be the
case everytime?
Thanks
James
