我正在尝试使用 selenium 将页面保存为整个 html，页面中有一个下拉列表。该列表中有 2 个元素，我想在单击每个元素后保存整个 html。
下面是我正在使用的代码：
devlink='http://www.t-mobile.com/content/tmo-wem/en/index/cell-phones/nokia-lumia-521.html'
devname= devlink[devlink.rfind("/")+1:]
ignore_tags=('script','noscript','style')
with contextlib.closing(webdriver.Firefox()) as browser:
browser.get(devlink) # Load page
dropdown = browser.find_element_by_class_name('dropdown-menu')
elements = dropdown.find_elements_by_tag_name('li')
i=0
for element in elements:
element.click()
i = i+1
time.sleep(2)
content=browser.page_source
cleaner=clean.Cleaner()
content=cleaner.clean_html(content)
with open(str(i)+devname,'w') as f:
f.write(content.encode('utf-8'))
这段代码给了我一个错误，它的回溯看起来像这样Traceback (most recent call last):

此代码无法单击它找到的 2 个元素，请帮助我解决此问题。
