title: Running JavaScript downloaded with XMLHttpRequest
body: <p>I have a site that loads information using the XMLHttpRequest when a user clicks a link. The system works well but I would like to be able to execute JavaScript gathered in this process.</p>
  
  <p>This is a problem as I would like to download the scripts 'on demand' if it were, rather than loading them all when the page is loaded.</p>
  
  <p>Thanks for any help</p>
