python - 有一个特殊的网页找不到任何元素

问题描述

该网站是https://www.gaitame.com/bo/demo.html

中间有一个带有日语“デモトレード版を利用する”的按钮

然后将转到这样的演示交易者页面

在此页面中，我无法获取任何元素

其他页面都可以

我已经切换到这个标签

请帮忙.............

这是我的测试代码

from selenium import webdriver
import time
url = 'https://www.gaitame.com/bo/demo.html'
driver = webdriver.Chrome()
driver.get(url)
# Click the button and wait for loading
driver.find_element_by_class_name("blue2btn").click()
time.sleep(5)
# Switch to another tab
driver.switch_to.window(driver.window_handles[1])
# Try find any elements
driver.find_elements_by_class_name("header_area")

这是错误消息
