切换到Selenium中包含登录提示的框架

我正尝试使用Selenium登录到ESPN。过去的解决方案详述如下：here。为了登录，我需要找到具有用户名和密码字段的框架并切换到该框架。不幸的是，该框架的数字指标并不总是相同的。我决定尝试所有这些，但只要我切换到一帧，切换到下一个失败，selenium.common.exceptions.StaleElementReferenceException: Message: The element reference of <iframe class="ob-pifr"> stale: either the element is no longer attached to the DOM or the page has been refreshed。所以我在寻找切换到Selenium中包含登录提示的框架

来切换图像，而不StaleElementReferenceException
一种方法来检查帧是否是一个我想之前，我切换到它
一些其他的解决方案的一种方式，但我ð喜欢的东西内省的魔法（大概脆弱）公式像“它总是从最终的第3张）

下面是一些示例代码，导致StaleElementReferenceException：

from time import sleep 
from selenium import webdriver 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.by import By 
from selenium.common.exceptions import NoSuchElementException 


driver = webdriver.Firefox(executable_path = '/usr/local/bin/geckodriver') 
driver.get("http://games.espn.go.com/ffl/signin") 
WebDriverWait(driver, 1000).until(EC.presence_of_all_elements_located((By.XPATH,"(//iframe)"))) 

elem = None 
frms = driver.find_elements_by_xpath("(//iframe)") 
print("Found {} frames", len(frms)) # Varies from 6 to 8 
for count, frm in enumerate(frms): 
    print("Trying frm[{}]".format(count)) 
    driver.switch_to.frame(frm) 
    sleep(2) 
    try: 
     # The command below will fail the second time around with 
     # `either the element is no longer attached to the DOM or the page has been refreshed` 
     elem = driver.find_element_by_xpath("(//input)[1]") 
    except NoSuchElementException: 
     pass 
    else: 
     break

帧ID是disneyid-iframe其所以首先打开登录弹出你需要切换到它

driver.switch_to_frame(driver.find_element_by_id("disneyid-iframe"))

，然后执行类似

driver.find_element_by_xpath("//input[@type='email']").send_keys("emailid") 

driver.find_element_by_xpath("//input[@type='password']").send_keys("password")

其他方式的SendKeys帧切换时ExplicitWait。它等到框架可一旦有那么它得到

wait = WebDriverWait(driver, 60) 

wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID, "disneyid-iframe")))

您的最终代码转换将是：

from time import sleep 
from selenium import webdriver 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.by import By 
from selenium.common.exceptions import NoSuchElementException 


driver = webdriver.Firefox(executable_path = '/usr/local/bin/geckodriver') 
driver.get("http://games.espn.go.com/ffl/signin") 

wait = WebDriverWait(driver, 60) 

wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID, "disneyid-iframe"))) 


driver.find_element_by_xpath("//input[@type='email']").send_keys("emailid") 
driver.find_element_by_xpath("//input[@type='password']").send_keys("password") 
driver.find_element_by_xpath("//button[@type='submit']").click()

注意：请检查语法按Python的。
