python - Selenium w/Python3 - AttributeError : 'str' object has no attribute 'tag_name'

Question

Selenium/Python 自动化新手。我无法自动填写注册表单。下拉菜单是必需的元素，但我收到以下错误...

属性错误:“str”对象没有属性“tag_name”

我已经在下面发布了我的代码，但在网上找不到任何关于为什么会这样的答案。非常感谢任何/所有帮助。

from selenium import webdriver
from selenium.webdriver.support.select import Select
teamElement = browser.find_element_by_id('id_team')
time.sleep(2)
sel = Select('teamElement')
sel.select_by_value("12")

错误来自 sel = Select('teamElement') 行。

 Traceback (most recent call last):
 File "/Users/jamesstott/PycharmProjects/basics/RunChromeTests.py", 
 line 40, in <module>
 sel = Select('teamElement')
 File "/Users/jamesstott/PycharmProjects/venv/lib/python3.6/site-packages/selenium/webdriver/support/select.py", line 36, in __init__
 if webelement.tag_name.lower() != "select":
 AttributeError: 'str' object has no attribute 'tag_name'

Answer 1

Select 采用 WebElement 类型参数而不是字符串类型。更改以下行

sel = Select('teamElement')

至

sel = Select(teamElement)

完整代码，

from selenium import webdriver
from selenium.webdriver.support.select import Select
teamElement = browser.find_element_by_id('id_team')
time.sleep(2)
sel = Select(teamElement)
sel.select_by_value("12")
