css - Watir::Exception::MissingWayOfFindingObjectException:无效属性::css

Question

我很确定 watir-webdriver 支持 css 选择器，但看起来它不再存在了:

$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]

$ gem -v
1.8.15

$ gem list selenium-webdriver
*** LOCAL GEMS ***
selenium-webdriver (2.17.0)

$ gem list watir-webdriver
*** LOCAL GEMS ***
watir-webdriver (0.4.1)

$ irb
> require "watir-webdriver"
 => true 

> browser = Watir::Browser.new :firefox
 => #<Watir::Browser:0x787eb29124fb7658 url="about:blank" title=""> 

> browser.goto "google.com"
 => "http://www.google.com.mx/" 

> browser.a(:css => "a").flash

环境:Mac OS X 10.7.2、Firefox 9.0.1。

我做错了什么吗？

Answer 1

watir-webdriver 目前只在你使用 Browser#element 时支持这个

 browser.element(:css => "a")

我们可以添加对其他元素方法的支持，但我们必须找到一种方法来处理例如

 browser.a(:css => "div.foo")
