[Tutor] opening a javascript window and reading its source

[Remco Gerlich]

Hi,

Python can't run Javascript functions. Note that "HTTPCookieProcessor"
is a HTTP thing, so it can handle  "http:" links, not "javascript:"
links.

Your best bet would probably be to download all the Javascript files
mentioned in the original HTML file, and try to find out what the
toggleBackpack() function does. If you can find out from that
Javascript function what the URL is that it opens in the new window,
then you can download that same URL from Python.

There is no such thing as a "Javascript window". Javascript can be
used to open perfectly normal windows, that contain normal HTML.

It's hard to give more help without knowing more about your problem.

Hope this helps a little,
Remco Gerlich
