硒：如何看到完整的DOM结构？

Question

我看到了有关此问题的类似帖子，分辨率是使用WebDriverWait。但是我仍然会遇到一个异常错误，认为选择器不存在。 即使我打印driver.execute_script（“ return document.body.innerhtml;”在我的代码结束时，完整的DOM并未显示，它看起来完全像页面源，但我需要HTML的其余部分

from multiprocessing.connection import wait
from ntpath import join
import os
from xml.dom.minidom import Element
from selenium import webdriver
from selenium.webdriver.common.by import By ## Used for grabbing elements by 
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
import time

os.environ['PATH'] += ";C:\seleniumDrivers"
chrome = webdriver.Chrome()
chrome.get("https://jklm.fun/XSNM")

chrome.implicitly_wait(10)
name = chrome.find_element(By.CLASS_NAME, "nickname")
name.clear()
name.send_keys("Mr.Roboto")

btn = chrome.find_element(By.XPATH, '/html/body/div[2]/div[3]/form/div[2]/button')
btn.click()

join_btn = WebDriverWait(chrome, 1000000).until(EC.presence_of_element_located(
    chrome.find_element(
    By.XPATH, '/html/body/div[2]/div[3]/div[1]/div[1]/button')))
#join_btn = chrome.find_element(By.XPATH, '/html/body/div[2]/div[3]/div[1]/div[1]/button')
#join_btn = chrome.find_element(By.CSS_SELECTOR, 'button[data-text="joinGame"')
join_btn.click()
