python - 无法使用 Selenium 选择下拉值

Question

我正在尝试使用此代码选择下拉值之一，但没有任何反应：

selectopt = Select(driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-bc-reservation/div/div[1]/div[1]/select'))
selectopt.select_by_value('1cfc3cd0ac77bba30ffac794183100dc220758511a6c943264f8273d90eb54c2')

还尝试通过以下方式选择：

select_by_visible_text
select_by_index

没发生什么事 ：（

更新：

添加完整代码，稍作改动，仍然是同样的问题。

代码将您定向到该页面，执行一些操作，在最后一页，我需要这个机器人从下拉列表中选择项目，但我无法做到。

它所需要的只是显式等待。

试试这个：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(30)
driver.get("https://eregitra.lt/advance-reservation/service")
wait = WebDriverWait(driver, 10)

vehicRegBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-service/div/div/div/button[1]')
vehicRegBut.click()

OneVehicRegBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-service/div/div/div[1]/button')
OneVehicRegBut.click()

NatPersonBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div/div[1]/button[1]')
NatPersonBut.click()

Name = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[1]/input')
Name.send_keys('Name')

SurName = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[2]/input')
SurName.send_keys('Surname')

Email = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[3]/input')
Email.send_keys('[e-mail]')

Tel = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[4]/div/input')
Tel.send_keys('65555560')

CheckBox = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[2]/div[1]/p-checkbox/input')
CheckBox.click()

NextBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[3]/div[2]/button')
NextBut.click()

select_ = wait.until(EC.visibility_of_element_located((By.XPATH, "//select[contains(@class, 'select-text smaller-text')]")))
selectopt = Select(select_)
selectopt.select_by_value('1cfc3cd0ac77bba30ffac794183100dc220758511a6c943264f8273d90eb54c2')
