Question

我需要循环遍历网页的元素并从每个元素中删除数据，但是每25秒我们的元素会不断刷新，而且我的代码在这段时间内没有完成所有元素的迭代，之后我得到了element is not attached to the page document错误：

driver.get("https://www.luckia.es/apuestas")
time.sleep(5)
driver.switch_to.frame("sbtechBC")
eventos_de_hoy=driver.find_element_by_id("today_event_btn")
eventos_de_hoy.click()
time.sleep(7)
ligi = driver.find_elements_by_class_name("leagueWindow ")
print(len(ligi))
for items in ligi:
    driver.execute_script("arguments[0].scrollIntoView(true);", items)
    nume_liga= items.find_element_by_tag_name("h5")
    print(nume_liga.text)

我的想法很新鲜。

您可以尝试以下代码以避免StaleElementReferenceException上的脚本制动：

from selenium import webdriver
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.common.exceptions import StaleElementReferenceException

driver = webdriver.Chrome()
driver.get("https://www.luckia.es/apuestas")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it("sbtechBC"))
eventos_de_hoy = driver.find_element_by_id("today_event_btn")
eventos_de_hoy.click()

ligi_len = len(WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "leagueWindow "))))
print(ligi_len)
for index in range(ligi_len):
    try:
        item = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "leagueWindow ")))[index]
        driver.execute_script("arguments[0].scrollIntoView(true);", item)
        nume_liga = item.find_element_by_tag_name("h5")
        print(nume_liga.text)
    except StaleElementReferenceException:
        item = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "leagueWindow ")))[index]
        driver.execute_script("arguments[0].scrollIntoView(true);", item)
        nume_liga = item.find_element_by_tag_name("h5")
        print(nume_liga.text)
