Hi T.J, I'm not able to use the AJAX.Updater because of policy regarding AJAX requests require me to use another ajax. Suffice to say by the time I see the response it's two strings one with HTML and one with JavaScript.
Here is the path I followed to get where I'm at. The following sample code (in my opinion) should correctly register the myfunction() and then allow me to call it. This is not the case and I get 'myfunction is not defined' in firefox, and the ever unhelpful Object Expected in IE. <head> <script src="assets/js/prototype-1.6.0.3.js" type="text/javascript"></ script> <script type="text/javascript"> Event.observe(window, 'load', function() { $('container').update("<p>New HTML</p> <script> alert('this will'); function myfunction(){ alert('this wont!'); } <\/script>"); // Fire the new function... does not work? myfunction(); }); </script> </head> <body> <div id="container"> Old Content.</div> </body> </html> Swapping around, as the documentation suggested, to var myfunction = function(){ alert('this wont!'); } also fails. but here is where it gets interesting, both of the following work... eval("var myfunction2 = function(){ alert('this will 2!'); };" ) myfunction2(); eval("function myfunction3() { alert('this will 3!'); } " ) myfunction3(); So I'd have to conclude that prototype does not eval scripts in the same way as the eval() function does.? of course [hitting head on keyboard] that just gave me the solution... don't use prototype to inject the js. :) eval(new_content_js); var function_name = 'template_'+ template_name +'_onload'; eval(function_name + '();' ); Still an interesting exercise and life experience.

Both kinds of declarations work fine (on FF3, IE6, Safari > 3.1.2, and Opera 9.1 -- all on Windows).
