我使用 watir-webdriver 来自动化一些日常任务，最近我完美的工作脚本在开始时中止了。当我使用 browser.goto "webpage" 时，网页没有完全加载，因为页面底部有一个计数器，并且计数器服务似乎暂时关闭。有时它会加载，有时不会。否则，我需要的所有 html 元素都已加载且可见，但页面无法完全加载，因此 30 秒后我总是收到 tiemout 错误，并且我的 Ruby 脚本以以下错误消息终止：

/opt/ruby1.8/lib/ruby/1.8/timeout.rb:64:in `rbuf_fill': execution expired (Timeout::Error)
    from /opt/ruby1.8/lib/ruby/1.8/net/protocol.rb:134:in `rbuf_fill'

    from /opt/ruby1.8/lib/ruby/gems/1.8/gems/watir-webdriver-0.6.1/lib/watir-webdriver/browser.rb:63:in `goto'

有什么方法可以避免程序终止并使用未完全加载的页面？我的意思是如果可能的话，任何超时异常处理，最重要的是我的 Ruby 脚本继续没有终止。我试过这个，但没有奏效，因为我只是 3 天的 ruby​​ 程序员：

begin
  browser.goto "http://example.com"
rescue Watir::Exception::NavigationException => e #catch the Exception
  puts "Page did not load: #{e}" 
  # program continues from here 
end

尝试救援Timeout::Error而不是Watir::Exception::NavigationException.
