:) I don't think so.  What would be doable (I think) would be to interpret a
:) subset of JS (the parts that generate html on the fly).

I have been looking at the problem since some time ago, you can make easy
subsitution when you have urls of the form

  'http://www.cnn.com/' + tail

where tail is some variable, I think this is easy to support but it's too
restricted to call it a contribution to anything.

  The problem is that Javascript is a programming language, you need to
support expressions like

  if (this condition) then
     variable = window.open('http://this.address'+info+'.html', etc, etc)
  else
     variable = window.open('http://other.address', etc, etc)

and so on. A job like this requires that you have a way to get values of
JS variables from the document itself, for example, when doing forms, so
you need to consider that this means that a lot of new functions must be
added to the library. You would need to keep the document in memory (or on
file), is this already done? I believe that you can get relatively good
success if you get a good way to parse documents that contain expressions
like above and ignore what really does not apply to lynx.
