Answer 1

解决方案 1：使用 css 定位器

您必须使用 css-locator（或 xpath）：

carGroup = browser.span(:css, 'span[name="tab4RateInfoForm.vehicleGroup"]').text

解决方案 2：猴子补丁

或者，如果您有很多使用 name 属性的旧脚本，您可以修改 Watir 以使所有元素（或特定元素，如果需要）具有 name 方法。

将以下内容添加到您需要的地方：

Watir::IE.new(true)
module Watir
  class Element
    def name
      return self.attribute_value('name')
    end
  end
end

您原来的方法现在应该可以工作了。

Answer 2

看起来span 元素不能再通过name 属性访问。

试试这个（使用通用的element 而不是span）：

carGroup=browser.element(:name => 'tab4RateInfoForm.vehicleGroup').text
