Undead gets Dynamic HTML. Dynamic HTML are created by JavaScript.
Add this line to your application's Gemfile:
gem 'undead'And then execute:
$ bundle
Or install it yourself as:
$ gem install undead
You need at least PhantomJS 1.8.1. There are no other external dependencies (you don't need Qt, or a running X server, etc.)
- Homebrew:
brew install phantomjs - MacPorts:
sudo port install phantomjs - Manual install: Download this
- Download the precompiled binary for Windows
Do this as a last resort if the binaries don't work for you. It will take quite a long time as it has to build WebKit.
- Download the source tarball
- Extract and cd in
./build.sh
(See also the PhantomJS building guide.)

Undead.get can get Dynamic HTML. <script> is evaluated, then HTML is created.
