Executing javascript from Ruby

[bcparanj]

I need to execute a javascript from Ruby. The result of the javascript
is a URL. I could not find anything that help bridge the gap between
javascript and Ruby. Does anyone know if there is something that I can
use for this problem? TIA.

Hi ---

do you want to open the URL in Ruby ?
There are many possibilities: look eg. here:

Yes.... Johnson bridges Ruby to JavaScript. We haven't released a gem
yet, but you can check it out from github now. Its pretty stable, and
we only have 1 bug blocking our release.

http://github.com/jbarnette/johnson/tree/master

Example:

context = Johnson::Context.new
context.evaluate("function foo() { return 'hello world'; }")
context.evaluate("foo()") # => 'hello world'
