Rails spinoffs - Oct 2005 - AJAX and disapear javascript tags

Hello everyone.
 I''m writing web aplications using AJAX (library prototype and
scriptaculous). I have situation that I want to change content of one div in my
site. I  make ajax request to server and getting new content of that div. The
problem is that this div should have javascript code (e.g. looks like that
<div><script>js code</script>
<ul></ul></div>) but haven''t. I can see the server
response and everything is ok, (the AJAX data pack is ok, have js code in div),
i can see the data just moment before browser is getting it (thanks for
greasemonkey!) and still everything is ok, but when browser is changing that div
on my site the js code is gone! What I''m doing wrong? or this is not a
good way and i shouldn''t doo like that?
I cant make it alone so thanks for any help

Yeah, I think you''re tackling this the wrong way.

You need to split up the response. If you want to show just HTML then show
it, if you want to execute javascript then return that separately and then
run an eval() on it.

Cheers,
Bruce

Prototype automatically executes JavaScript code inside <script> tags  
because your browser won''t when replacing elements contents (some  
browsers actually *might* execute the code, but it''s not reliable  
across the supported browsers). It then throws away the script tags,  
because they are useless. Any functions and code you define inside  
them will still be available.

You need to define the evalScripts:true option in your new  
Ajax.Updater() call.

So you''re not doing anything wrong. :)
