python中的Selenium在单击隐藏单选按钮时出现问题

Question

使用driver.find_元素（）可以定位按钮，但在此之后，我使用click（）然后弹出一些错误，如下所示：

  File "C:\Python34\lib\site-packages\selenium\webdriver\remote\webelement.py", line 65, in click
    self._execute(Command.CLICK_ELEMENT)
  File "C:\Python34\lib\site-packages\selenium\webdriver\remote\webelement.py", line 385, in _execute
    return self._parent.execute(command, params)
  File "C:\Python34\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 173, in execute
    self.error_handler.check_response(response)
  File "C:\Python34\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 166, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotVisibleException: Message: 'Element is not currently visible and so may not be interacted with' ; Stacktrace:

为什么会这样？在

错误消息告诉您发生这种情况的确切原因：

Element is not currently visible and so may not be interacted with

Selenium只允许您与可见元素交互，前提是如果它是不可见的，那么用户不能与它交互，如果用户不能与它交互，那么Selenium也不能。在
