硒未装载在聚会技术中显示更多

如何解决硒未装载在聚会技术中显示更多

我花了近几天的时间来解决这个问题，但没有成功:(有人可以帮忙吗？基本上是在metup网站上针对给定城市的内容，当硒单击“显示更多”时，它会加载但没有任何显示，但是如果我这样做了手动在相同的链接上进行操作。任何帮助将不胜感激。PS我是新手，所以不要难：）

解决方法

尝试此代码

from selenium import webdriver
import time

url = 'https://www.meetup.com/find/?allMeetups=true&radius=100&userFreeform=Rio+de+Janeiro%2C+Brazil&mcId=c1002406&mcName=Rio+de+Janeiro%2C+BR&sort=recommended'

browser = webdriver.Chrome('C:\\seleniumDrivers\\chromedriver.exe')
getr = browser.get(url)
browser.maximize_window()

def clickonce():
    time.sleep(3)
    browser.execute_script("window.scrollTo(0,document.body.scrollHeight);")
    time.sleep(5)
    browser.find_element_by_xpath("//span[contains(text(),'Show more')]").click()

def scrolldown():
    time.sleep(3)
    browser.execute_script("window.scrollTo(0,document.body.scrollHeight);")
    time.sleep(5)

clickonce()
while True:
    scrolldown()
