thanks a lot for your patience and all these useful hints ! :)

I'm working on a standalone C++ app. The Frontend/UI is the Gecko-Engine
that is embedded in the backend written in C++. All what a webserver does
shall later be done by the C++ backend. Therefore my web code hast just to
be compliant with Firefox/Gecko.

Yes. The show( AJAX_data ) function helps to substitute the total content of
"#MyDiv". The total substitution of all present <p>'s ( with the old one +
the new one) in #MyDiv using show() seemed to be the most easiest way (1)
not only showing the (added) new paragraph, but also (provide) ALL <p>'s
with the click handler.

I have to take some lessons in Javascript OOP

that's the CENTER OF MY TROUBLE. I did speak about the reason for using the
show() function above.
But maybe I can get your patience for one more special example that desribes
my intention and trouble more precisely: Let's assume I work on a web site
that should display the paragraphs of a book. The book has chapters and each
chapter has <p>s. I start displaying the first <p> (of the first chapter).
When read by the user he clicks on the <p> and the next paragraph will
shown.
$("#MyDiv").append(next_pragraph_from_AJAX_call).click( function()
{
get_next_paragraph_via_AJAX
}
I can go on this way until the last <p> of the current chapter is
added/shown. Now I should start with the first <p> of the second chapter.
Therefore I have to delete all <p>'s (of chapter 1) and show the first <p>
of chapter 2. This is what my show()-function should do (that bothers you
[and me too]): replace all current shown <p>'s and RE-START with one <p> -
the first one of chapter 2.
Do you have any hint how to do it better ?
sincerely
