无法在 selenium chromedriver 中找到元素，即使它存在

Question

我正在尝试单击thetimes.co.uk网站上的“ I Agree ”按钮，但是会引发异常，指出找不到该元素。

这是我尝试过的：

import time
from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.thetimes.co.uk/")

time.sleep(1)

# Neither one of the below worked:
driver.find_element_by_xpath("/html/body/div/div[3]/div[3]/button[2]").click()
driver.find_element_by_css_selector("body > div > div.message.type-modal > div.message-component.message-row > button:nth-child(3)").click()
driver.find_element_by_css_selector(".message-component.message-button.no-children").click()

是否有任何 cookie 可以发送到网站以禁用弹出窗口或成功单击“ I Agree ”按钮？

Answer 1

您遇到了一个经典的 iframe 问题，“我同意”按钮位于内部 HTML 文档中，您需要先切换到它才能找到该按钮； 请参阅下面的代码示例，

import time

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 import webdriver

driver = webdriver.Chrome("./chromedriver")
driver.get("https://www.thetimes.co.uk/")

iframe = (By.CSS_SELECTOR, "#sp_message_iframe_216133")
btn_agree = (By.CSS_SELECTOR, "body > div > div.message.type-modal > div.message-component.message-row > button:nth-child(3)")

iframe_element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(iframe))
driver.switch_to.frame(iframe_element)
WebDriverWait(driver, 10).until(EC.element_to_be_clickable(btn_agree)).click()

# remember to switch back out
driver.switch_to.default_content()
