Selenium2 WebDriver Ruby => how click on a hidden link

Question

I use Selenium 2 WebDriver on Ruby.

How it is possible click on hidden link, with css (display: none)? the link is submenu and is visible when mouse over on menu.

Answer 1

In the past, if I have not had much luck with the ActionBuilder methods, I just use pure javascript:

def mouse_over_and_out(element)
  @driver.execute_script("if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}", element)
  yield element
  @driver.execute_script("if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseout', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseout');}", element)
end

def wait_for_visibility(element) 
  wait = Selenium::WebDriver::Wait.new(:timeout => 15)
  wait.until do
    element.visible?
  end
  element
end

mouse_over_and_out(@driver.find_element(:css => "ul#nav-main li")) do |menu|
  submenu = menu.find_element(:css => "ul li a")
  wait_for_visibility(submenu).click
end
