我在Selenium的這個ElementNotVisibleException問題上看到了很多問題/回答。 到目前爲止，我已經做了最好的代碼如下：Selenium - ElementNotVisibleException
from selenium.webdriver.support.ui import WebDriverWait
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
url = "http://www.cfnews.net/user/login"
driver.get(url)
print "Got url."
wait = WebDriverWait(driver, 10)
login_form = wait.until(EC.invisibility_of_element_located((By.ID, "user-login")), "pbm")
print "Element located."
displayed = login_form.is_displayed()
print "login_form.is_displayed() = ", displayed
login_form.send_keys("a")
這給下面的輸出：
Got url.
Element located.
login_form.is_displayed() = False

ElementNotVisibleException Traceback (most recent call last)

所以，下載該網頁時，HTML是由司機下車，但它不可能發送任何密鑰。 還有這裏的答案：哪些建議使用ActionChain Selenium Element not visible exception
，但我想沒有成功:(
如果我做的：
driver.page_source
我得到的HTML：
