Capybara testing value of hidden field

Actually, it seems that you can just send a \n to capybara's native set method and achieve the same effect (in a more flexible, driver agnostic way).

So in my code, this is currently working to trigger a form submit event (handled by JS):

  field = find("form input[type=text]")
  field.set "my comment\n"

(Note that, as the author of the pull request explains here, this only works if you're binding to the specific keydown event, not if you're binding to the form submit that should result from it.)

I found the following worked for me:

# Check
find(:css, "#cityID[value='62']").set(true)

# Uncheck
find(:css, "#cityID[value='62']").set(false)
