试图使用python上的硒滚动弹出弹出式弹出弹出时，对象无法相互作用

Question

我需要向下滚动以下链接中出现的弹出窗口 https://www.vivino.com/it/en/en/rronchi-di-cialla-picolit-di-cialla/w/2015576?year=2011＆amp;pprice_id = 23500586 （或Vivino上的任何其他葡萄酒链接）单击“显示更多评论”后，但是当我尝试滚动时，我会发现元素无法相互作用的错误。 弹出评论的代码是以下

from urllib.request import urlretrieve
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
import pandas as pd
import csv
import re
import time
import random



target_url = 'https://www.vivino.com/IT/it/ronchi-di-cialla-picolit-di-cialla/w/2015576?year=2011&price_id=23500586'
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option("useAutomationExtension", False)




driver = webdriver.Chrome(options=options)
driver.get(target_url) #apre la pagina

last_height = driver.execute_script("return document.body.scrollHeight") 

while True:
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight/3);")
    time.sleep(1)
    driver.execute_script("window.scrollTo(document.body.scrollHeight/3, document.body.scrollHeight*2/3);")
    time.sleep(1)
    driver.execute_script("window.scrollTo(document.body.scrollHeight*2/3, document.body.scrollHeight);")
    
    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height
    
driver.find_element(By.CSS_SELECTOR, "button[class='MuiButtonBase-root MuiButton-root jss1 MuiButton-outlined jss3 MuiButton-disableElevation']").click()

这是每1秒钟向下滚动到每个评论的代码。我建议您不要直接在评论上循环，即不要做类似的事情

reviews = driver.find_elements(By.XPATH, "//div[contains(@class, 'allReviews__reviews')]/child::div")
for review in reviews:
    ...

，因为最初只加载了很少的评论，然后随着您向下滚动时，会加载更多的评论。因此，如果您使用上述代码评论将仅包含第一个加载的评论。下面的代码解决了此问题，但是如果总评论的数量小于limit，则将失败。因此，您应该改进代码以考虑到这一事实

target_url = 'https://www.vivino.com/IT/it/ronchi-di-cialla-picolit-di-cialla/w/2015576?year=2011&price_id=23500586'
driver.get(target_url)
# go to reviews section
driver.get(target_url + '#all_reviews')
# click on show more reviews
driver.find_element(By.XPATH, "//span[contains(text(), 'Mostra altre recensioni')]/../..").click()
# scroll down to each review, one by one in a loop
limit = 20
for idx in range(limit):
    reviews = driver.find_elements(By.XPATH, "//div[contains(@class, 'allReviews__reviews')]/child::div")
    driver.execute_script('arguments[0].scrollIntoView({block: "center", behavior: "smooth"});', reviews[idx])
    time.sleep(1)
