What do you mean by "send javascript commands"??

I had some success back in 2002 using Mozilla's Spidermonkey
javascript engine to process a proxy autoconfig file to decide whether
to use a proxy or not. I used curl to grab the autoconfig file from
the server, tacked on a small block of required functions and pushed
it through js. The result was either "DIRECT" or the name of the
proxy to use.

If you're hoping to process a web page and "do the right thing" for
the javascript it contains, there's a *lot* more work involved. You'd
probably end up writing a large fraction of a web browser to be able
to handle all the javascript that could show up.
