This has been covered many times before. You don't need to try and run the JavaScript any more than you need to try and render the HTML. The server only sees the HTTP interaction, so all you need to do is mimic what your browser actually sends to the server.

As it happens, you're in luck, because there is a recent article about how to capture this HTTP interaction with minimal effort:

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
