Yes, I'm trying to fix something that isn't broken.

No, I'm not using ajax to to register the events.  By "get rid of my
inline onclicks" simply means removing the onclick from my <a
href=..."> tags and apply with something like Event.Observe().


I've got a <div> that is updated by an ajax request, say clicking on a
table heading sorts by that column, or selecting a tab as in the
example below).  The links (with the onclick behavior) are included
*within* the <div>.

If the onclick is in-lined into those links returned in the ajax
response, then all is well;  they get set when the response is
processed by the browser.  Here's an example of that method:

    http://hank.org/demos/ajax-inline.html



Now, since I'm trying to get rid of the in-line onclick on my <a>
elements, I need a way to re-assign the event handlers to the <a>
elements after the ajax update.

What I'm doing now is including a <script> section in the ajax update

    http://hank.org/demos/ajax.html

and telling Prototype's Ajax.Updater to run any <script> sections
returned in the ajax response, as you can see in this response:

    http://hank.org/demos/recent


I posted about this earlier on the Rails spinoff list (which sometimes
discusses Prototype).  Sorry for any duplicates.
