我想点击悬停后可见的按钮.它的
HTML是：
<span class="info"></span>
我用过这段代码：
import selenium.webdriver as webdriver
from selenium.webdriver.common.action_chains import ActionChains
url = "http://example.com"
driver = webdriver.Firefox()
driver.get(url)
element = driver.find_element_by_class_name("info")
hov = ActionChains(driver).move_to_element(element)
hov.perform()
element.click()
虽然不行.我得到一个错误连接到最后一行代码element.click()：
selenium.common.exceptions.ElementNotVisibleException: Message: \ u'Element is not currently visible and so may not be interacted with'
有什么建议吗？
