ruby - 如何使用 watir-webdriver 从 text_area 调用 id？

Question

for i in 0..10
  if @b.text_field(:cols  => "40", :index => i).exists?
    id = @b.text_field(:cols  => "40", :index => i)
    if profile_profile_qualifications_attributes_new_(\d)+_comment/.match(id)
      @b.text_field(:cols  => "40", :index => i).set "Rock!"
    end
  end
end

上面的代码失败了

Error: can't convert Watir::TextField to String (TypeError)

Answer 1

id = @b.text_field(:cols  => "40", :index => i).id
