Answer 1

您可以使用 presence_of_element_located 和 explicit waiting使用 css 选择器定位元素:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException

try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.CSS_SELECTOR, "option[value='123']"))
    )
    print("Option loaded")
except TimeoutException:
    print("Time exceeded!")
