单击单选按钮时的问题无法选择单选按钮。消息：过时的元素引用：元素未附加到页面文档

Question

错误：selenium.common.exceptions.StaleElementReferenceException：消息：过时的元素引用：元素未附加到页面文档。

我正在抓取的网站https://www.telekom.de/unterwegs/apple/apple-iphone-13-pro/graphit-512gb 我想在每个部分循环这个关税细节，每个单选按钮显示不同的价格。我想一一抓取每个单选按钮的价格详细信息，并检查单选按钮名称以及价格，直到页面末尾。我已经尝试过，但我无法成功。

任何人都可以帮助解决这个问题。我会帮助我学习。我一直在尝试更改关税链接，但我正面临着获取详细信息的问题。更改以下链接中给出的关税链接，

Answer 1

选择不同的选项后，页面会刷新，因此出现了问题。我无法找到您尝试单击代码中按钮的位置。因此尝试使用以下代码单击所有radio buttons 并成功。检查代码一次。

from selenium import webdriver
import time
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

driver = webdriver.Chrome(executable_path="path to chromedriver.exe")
driver.maximize_window()
driver.implicitly_wait(10)

driver.get("https://www.telekom.de/unterwegs/apple/apple-iphone-13-pro/sierrablau-128gb")
wait = WebDriverWait(driver,30)
wait.until(EC.element_to_be_clickable((By.XPATH,"//button[text()='Accept All']"))).click()

radiooptions = wait.until(EC.presence_of_all_elements_located((By.XPATH,"//span[@class='phx-radio__element']")))

for i in range(len(radiooptions)):
    radiooptions = driver.find_elements_by_xpath("//span[@class='phx-radio__element']")
    radiooptions[i].click()
    time.sleep(2)

Answer 2

请用 li 元素代替 span

//li[@data-qa='list_ColorVariant']

点击后还会添加等待。 5 秒。然后点击下一个
