Watir::Exception::MissingWayOfFindingObjectException: invalid attribute: :css

问题

I am pretty sure watir-webdriver had css selector support, but looks like it is not there any more:

$ 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

Am I doing something wrong?

回答1:

watir-webdriver currently only supports this if you use Browser#element

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

We could add support for other element methods, but we'd have to find a way to handle e.g.

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

回答2:

Funny, enough I can still bypass a lot of limitations or missing functionality not exposed by watir making direct JS calls, e.g.

browser.execute_script('jQuery(\'div#td%s div a\').trigger(\'click\')' % reagent_id)

As I said, in some cases this the only way for me. It would be really cool to have a tighter integration into the DOM.
