Dear Angel, thanks for answering, but your suggestion does not solve this problem. See below

Hello, Romuald

There may be several issues there, but there must be a simple solution.


and a div container in which 
external html pages are loaded. 

Is that an IFRAME? Otherwise, I am not sure how an external page may be 
loaded into a div, that could be donde by the jQuery library but it is not 
straightforward.
Actually, loading an html file into a div  container does work, and it is is still the case when I load external html pages that call jsmol. Every html instruction is well interpreted, with the exception of the pages that contain jsmol controls (buttons or checkboxes).
As far as I have read on forums, it seems to be possible to load external html files inside div containers. I have seen other possibilities with iframes, but I did not succeed either.
If you do use an iframe, then you can test your pages on their own before 
loading them as secondary pages. But there should be no difference.
I have tested the external pages individually (adding the call to jsmol.min.js, vide infra) and this case everything appears, including the jsmol applet and the control buttons.


Important: where do you issue the Jmol commands/links from? From the 
main page or from the secondary ones?
From the secondary one.


with links (such as <a href="" class="moz-txt-link-rfc2396E" href="_javascript_:Jmol.script(JmolPG,'select*;cartoonsoff;spacefillonly')">"_javascript_:Jmol.script(JmolPG,'select 
*;cartoons off;spacefill only')">spacefill</a>) 

There is a fundamental difference here. Script just sends instructions to 
Jmol, while the others create controls in the page. That may be why the first 
works for you but not the others.


, the applet and the rest 
of the external file appear in the div container, as desired. 

That's important, meaning your JSmol setup is correct.


I would have expected that you need to call Jsmol.min.js in the secondary 
page. I can see you found the contrary, don't know why.  Have you tested if 
the checkboxes etc work when you add that?
- without the call to jsmol.min.js in the external file : everything works fine with links only, but the checkbox is then the only thing that appears when it is additionally used
- with a call to jsmol.min.js in the external file : the links appear on the page, but it not the case anymore of the jsmol applet (and of the checkbox, of course)
  
Anyway, the problem may be that the Jmol object is not created --so it 
seems-- until the page has finished loading, but the code for the controls is 
being run before, so maybe they fail because the Jmol object does not exist 
yet.
That is the reason why I have tried to define an asynchronous loading, but I am not sure that I really know how to do that
Oh, well, you have defined  JmolPG in advance, so that should not be the 
case. Maybe try these changes: give some value to the variable, then use 
the variable and not the text string:

var JmolPG = "JmolPG"; // within INITIALIZE JMOL

   $("#JmolappPG").html(Jmol.getAppletHtml(JmolPG, InfoPG))
// within $(document).ready(function() 

(Not sure about that, but could be the reason)
Good try, but unfortunately it is not the reason. This does not change anything.
