谷歌怎么定位事件的元素:难点

1. 定位hover事件，和对应click标签

   下面是代码触发

   	from selenium.webdriver.common.keys import Keys
   	from selenium.webdriver.common.action_chains import * # 动作
   	caipiaogames = handle.find_element_by_xpath('//*[@id="li_lotto"]')
   	actions = ActionChains(handle)
   	actions.move_to_element(caipiaogames)
   	actions.perform()
   	caipiaogames = handle.find_element_by_xpath('//*[@id="li_lotto"]/ul/li[3]/a')
   	actions = ActionChains(handle)
   	actions.move_to_element(caipiaogames).key_down(Keys.CONTROL).click(caipiaogames).key_up(Keys.CONTROL).perform()
