无法读取span元素

Question

嗨，因为我做了创业板安装watir watir-经典，我的脚本不再阅读跨元素。你能帮我解决这个问题吗？

这里是我的例子

源

Rented 
<SPAN class="displayData" style="padding-left:2px; width: 15;"><span name="tab4RateInfoForm.vehicleGroup"/>F</span></SPAN>&nbsp;

我的代码

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

错误消息

Answer 1

解决方案1:使用css定位器

您必须使用css定位器(或xpath)：

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

解决方案2:猴子补丁

或者，如果您有大量使用name属性的遗留脚本，您可以对Watir进行猴子补丁，使其具有所有元素的name方法(如果需要的话，可以使用特定的元素)。

在任何需要watir的地方添加以下内容：

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起作用了。

Answer 2

看起来span元素不能再通过name属性访问了。

试试这个(使用泛型element而不是span)：

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