使用scrolldown从表中抓取Selenium数据

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

driver = webdriver.Chrome('/path/to/chromedriver')
driver.get('https://example.com')

table = driver.find_element_by_xpath('//table')

while True:
    # 模拟按键向下滚动网页
    table.send_keys(Keys.PAGE_DOWN)
    
    # 等待加载新数据
    time.sleep(1)
    
    # 检查是否已滚动到底部
    if driver.execute_script('return document.body.scrollHeight') == last_height:
        break
    else:
        last_height = driver.execute_script('return document.body.scrollHeight')

data = []
rows = table.find_elements_by_xpath('.//tr')
for row in rows:
    cols = row.find_elements_by_xpath('.//td')
    row_data = [col.text for col in cols]
    data.append(row_data)

driver.quit()
# 处理抓取到的数据，如存储到数据库或进行进一步分析
