Selenium+Python想要实现：可以点击到对应的 选项 按钮，并选择下拉的某个值，比如5
selenium click select option and choose value
How to Select Option from DropDown using Selenium Webdriver
How to select a dropdown value in Selenium WebDriver using Java – Stack Overflow
此处不是select，子元素也不是option
且可以选择的value也没有，只有子元素a，里面的data-m的值是个json字符串，最后包含：itemCount":5，表示是第五个。
<ul id=”22bc22dd-ef9d-4d3c-8de9-1e7bc704f9f9_menu” role=”group” aria-labelledby=”22bc22dd-ef9d-4d3c-8de9-1e7bc704f9f9″ class=”dropdown-menu”>
<li role=”option”>
<a data-m=”{"aN":"shoppingCart","cN":"UpdateQuantity","bhvr":91,"pid":"8X58XHDX57SX","sku":"F96R","itemCount":1}” id=”22bc22dd-ef9d-4d3c-8de9-1e7bc704f9f9_menuItem_1″ class=”ember-view x-hidden-focus”> 1

Selecting a value from a drop-down option using selenium python – Stack Overflow
用xpath去选择，比较好。
如果不用option的value去选，倒是也可以考虑用index去选。
结果此处用：
cartNumOptionElemList = driver.find_elements_by_xpath(‘//ul[@class=”dropdown-menu”]/li[@role=”option”]’)
logging.info(“cartNumOptionElemList=%s”, cartNumOptionElemList)
carNumSelect = Select(cartNumOptionElemList)
carNumSelect.select_by_index(gCfg[“msStore”][“onceBuyNum”])
但是出错：
carNumSelect = Select(cartNumOptionElemList)
File “/usr/local/lib/python2.7/site-packages/selenium/webdriver/support/select.py”, line 36, in __init__
if webelement.tag_name.lower() != “select”:
AttributeError: ‘list’ object has no attribute ‘tag_name’
所以去改为：
直接用for循环就好了。
另外参考：
python – find_elements_by_partial_link_text won’t locate the elements – Stack Overflow
去试试之前就知道的：
Xpath中用contains／startWith
去实现，此处再次判断底层的tag中class／id等包含字符串／或者说 以字符串 开始
以便于更加精确的匹配：
具体写法，参考：
4. 查找元素 — Selenium-Python中文文档 2 documentation
starts-with [XPath 2.0 Reference @ Zvon.org]
contains [XPath 2.0 Reference @ Zvon.org]
更加精确的是：
matches [XPath 2.0 Reference @ Zvon.org]
结果：
【已解决】selenium.common.exceptions.ElementNotVisibleException Message element not visible
然后就可以获得对应列表元素，并点击了。
【总结】
代码：
<code>cartNumOptionElemList = driver.find_elements_by_xpath('//ul[@class="dropdown-menu"]/li[@role="option"]')
</code>对应网页：
点击了展开列表选项5之后效果：
