代码：
cartNumOptionElemList = driver.find_elements_by_xpath(‘//ul[@class=”dropdown-menu”]/li[@role=”option”]’)
cartNumOptionCount = len(cartNumOptionElemList)
logging.debug(“cartNumOptionElemList=%s,cartNumOptionCount=%s”, cartNumOptionElemList, cartNumOptionCount)
# toSelectNum = toProcessInfoDict[“orderNumber”]
toSelectNum = cartNumOptionCount
if cartNumOptionCount > toProcessInfoDict[“orderNumber”]:
logging.debug(“Current Cart select max number %s > remain buy number %s, so only need select %s”,
cartNumOptionCount, toProcessInfoDict[“orderNumber”], toProcessInfoDict[“orderNumber”])
toSelectNum = toProcessInfoDict[“orderNumber”]
logging.info(“Found cart number drop down list”)
toSelectIdx = toSelectNum – 1
carNumSelectElem = cartNumOptionElemList[toSelectIdx]
logging.debug(“carNumSelectElem=%s”, carNumSelectElem)
carNumSelectElem.click()

想要：鼠标滚动到可选择列表的底部
（然后再去点击）
很明显是还不可见就点击所以报错。

后来继续测试，结果又没法选择滚动去选择最后的30了，因为此时只能选择5个了：
不过暂时对于代码：
toSelectIdx = toSelectNum – 1
carNumSelectElem = cartNumOptionElemList[toSelectIdx]
logging.debug(“carNumSelectElem=%s”, carNumSelectElem)
# if not carNumSelectElem.is_displayed():
logging.info(“to select cart number element MAYBE invisible, now to scroll to visible”)
driver.execute_script(“arguments[0].scrollIntoView(true);”, carNumSelectElem)
去选择5个，是可以工作的:
【后记】
但是发现，更多的时候，对于5个时候，一次性都可以显示的时候：
结果代码都是出错：
<code> carNumSelectElem.click() File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webelement.py", line 80, in click self._execute(Command.CLICK_ELEMENT) File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webelement.py", line 501, in _execute return self._parent.execute(command, params) File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 308, in execute self.error_handler.check_response(response) File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.ElementNotVisibleException: Message: element not visible (Session info: chrome=63.0.3239.84) (Driver info: chromedriver=2.33.506106 (8a06c39c4582fbfbab6966dbb1c38a9173bfb1a2),platform=Mac OS X 10.13.2 x86_64) </code>
所以，看来这个办法是有问题的。
或者是需要优化的。
所以暂时还是注释掉代码。
等后续有30个可以选择，需要滚动的时候，再去测试。
【总结】
最后的相关代码是：
