I cannot think of a way to achieve this.
You could, however, include a list of filenames in your Javascript, and
then simply check it to see whether a particular file exists.
There are some problems, though:
you may not wish to give visitors a list of all the files;
the list may be rather long;
and it might be a pain keeping the list up-to-date. :(
Does your host offer server side scripting, such as PHP or Perl? That's
probably the best solution.
