I have an application that builds page content from multiple page fragments comprising the template page. One or more of these fragments need to run JavaScript when the document has loaded, and it does not make sense to put fragment specific code in the template page comprising the fragments. While this approach has worked out for me quite well, I have a problem when attempting to update a fragment via Ajax based on the user's interaction with the page.

I am using jQuery and $(document).ready(function() {...}); rather liberally, both in the template page (for globally scoped code) and the fragments (for fragment specific code). Problem is, when a fragment is updated using jQuery's .html(HTML code from Ajax response) on the jQuery enriched version of the HTML element and the Ajax response itself contains$(document).ready(function() {...}); code, the HTML content gets updated nicely but the JS does not execute.

Some suggest use of eval() on the JS fragments inside the Ajax response while others forbid it. I am hoping someone will push me in the right direction with this.
