Selenium：获取在“检查元素”中未显示的innerHTML的代码源

问题描述 投票：0回答：1

美好的一天！

我一直在浏览整个互联网，但没有发现像我这样的问题。

我正在尝试使用硒从'https://mobile.bet9ja.com/mobile'获取数据，我已逐步导航到所需的路径，直到到达所需的页面。

该页面将加载一张图片，然后经过一些我想要的时间数字和数据。

我的完整代码是：

import requests
from bs4 import BeautifulSoup
import lxml
from selenium import webdriver
import selenium
from selenium.webdriver.common.keys import Keys
import time
from selenium.webdriver import ActionChains

log_in_url = 'https://mobile.bet9ja.com/mobile/login'
driver = webdriver.Chrome('/Users/macbook/Downloads/chromedriver')
driver.get(log_in_url)
user_name = driver.find_element_by_css_selector("input.form-input[type='text']")
password = driver.find_element_by_css_selector("input.form-input[type='password']")
log_in_button = driver.find_element_by_tag_name('button')
user_name.clear()
password.clear()
# It needs log in
user_name.send_keys('user_name')
password.send_keys('password')
log_in_button.click()
time.sleep(5)

try:
    # Close a pop up window
    close_pop_up_window = driver.find_element_by_class_name('modal-close')
    close_pop_up_window.click()
except:
    pass

time.sleep(2)
league_button = driver.find_element_by_id('iconslider_1549_league_element')
league_button.click()
time.sleep(6)
premiere_legue = driver.find_element_by_class_name('col-xs-6')
premiere_legue.click()
time.sleep(15)

在我尝试了所有这些代码之后，它们返回了相同的结果：

html = driver.page_source()

和

html = driver.execute_script("return document.body.innerHTML")

和

html = driver.execute_script("return document.getElementsByTagName('html')[0].innerHTML")

结果是：

我曾尝试使用google chrome来检查该网页，并且我注意到当我第一次检查该网页时（请查看链接以获取屏幕截图）：

Screenshot of the code. The arrow points to the place where the code I need will be

并且当我第二次检查它时，我得到了所需的代码。

我确实投入了大量时间来寻找任何解决方案，但我一无所获。我很高兴在这里找到解决方案。

非常感谢

非常感谢@Sureshmani和@Anees Ijaz的评论。

因此，在您提出建议后，解决方案开始切换到iframe，这就是解决我的问题的方法：

iframe = driver.find_element_by_id('playAreaFrame')
driver.switch_to.frame(iframe)
print(driver.page_source)
driver.switch_to.default_content() #To switch back to the original content

非常感谢你们
