How to limit the amount of buttons Watir collects?

I'm collecting the follow buttons of twitter. How can I limit the buttons to just 30 buttons not everything on the page ?

    #Collect the "Follow" buttons
    browser.spans(:class => ['user-actions-follow-button js-follow-btn follow-button']).each do |b|

        #Click them! One by one.
        b.click

        # Generate random sleep period
        r = Random.rand(4...7)

        #Sleep so not to appear like a bot.
        sleep(r)
        # end
    end
Solution

  • Use #shift method

    browser.spans(:class => ['user-actions-follow-button js-follow-btn follow-button'])
    .to_a
    .shift(30)
    .each do |b|

  b.click

end
