title: Javascript source file download progress?
body: <p>I am sourcing a large mapping/widget javascript file (1.3 MB) and wanted to display a progress bar as it loads. I know firebug's net watch tab knows a lot of this information, but I would like something more lightweight. I came across this website:
  <a href="http://blog.greweb.fr/2012/04/work-in-progress/" rel="nofollow">http://blog.greweb.fr/2012/04/work-in-progress/</a> </p>
  
  <p>which almost gets me there except that I need to source the file I'm downloading. I didn't see any listeners on jQuery's getScript as the file downloads.  Does anyone know how to get at the progress of a sourced file download?</p>
  
  <p>Thanks in advance!</p>
