python - 如何通过 Selenium 和 Python 在我的页面上向下滚动？

Question

试图向下滚动到页面底部 https://silpo.ua/offers/?categoryId=13但是没有结果(没有动静)

我的代码:

import bs4
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

URL = "https://silpo.ua/offers/?categoryId=13"
driver = webdriver.Firefox()
driver.get(URL)

page = driver.find_element_by_tag_name("html")
page.send_keys(Keys.PAGE_DOWN)

html = driver.page_source

Answer 1

有几种方法可以向下滚动到页面底部。根据 url https://silpo.ua/offers/?categoryId=13，copyright 消息位于页面底部。因此，您可以使用 scrollIntoView() 方法在 Viewport 中滚动 copyright 消息如下:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

URL = "https://silpo.ua/offers/?categoryId=13"
driver = webdriver.Firefox(executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get(URL)
copyright = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.copyrights")))
driver.execute_script("return arguments[0].scrollIntoView(true);", copyright)
