something better than httrack to download files?

I am trying to download documents (pdf, tiff, images) from webpages that have javascript and frames in them. example: http://127.0.0.1/web/guest/en/websys/webArch/mainFrame.cgi

'httrack -开发者_如何学运维-get-files' didn't download any, are there other ways you may think of? another program? will I have to write that program myself?

Thanks a lot!
