Question

我在selenium的这个ElementNotVisibleException问题上看到了很多问题/答案。我到目前为止所做的最好的代码如下：

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")

给出以下输出：

Got url.
Element located.
login_form.is_displayed() =  False
---------------------------------------------------------------------------

     12 displayed = login_form.is_displayed()
     13 print "login_form.is_displayed() = ", displayed
---> 14 login_form.send_keys("a")

    493         params['id'] = self._id

    234         response = self.command_executor.execute(driver_command, params)
    235         if response:

    237             response['value'] = self._unwrap_value(
    238                 response.get('value', None))

/Users/romain/anaconda/lib/python2.7/site-packages/selenium/webdriver/remote/errorhandler.pyc in check_response(self, response)
    190         elif exception_class == UnexpectedAlertPresentException and 'alert' in value:
    191             raise exception_class(message, screen, stacktrace, value['alert'].get('text'))
--> 192         raise exception_class(message, screen, stacktrace)
    193 
    194     def _value_or_default(self, obj, key, default):

ElementNotVisibleException: Message: element not visible

因此，页面被下载，html由驱动程序获取，但是无法发送任何密钥。这里也有答案： Selenium Element not visible exception

建议使用ActionChain，但我尝试没有成功：（

如果我这样做：

driver.page_source

我得到了html：

u'<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://opengraphprotocol.org/schema/"><head>\n        \n                                                                                    \n<title>Ouverture de session / Utilisateur - l\'actualit\xe9 du capital investissement : transactions LBO, M&amp;A, Venture France - Corporate Finance et Private Equity</title>\n<meta name="description" content="CFNEWS est le premier site \xe0 proposer actualit\xe9s et r\xe9f\xe9rentiels du corporate finance en France sur les...etc...

Answer 1

试试这个并成功!!!

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

driver = webdriver.Firefox()
url      = "http://www.cfnews.net/user/login"
driver.get(url)

wait = WebDriverWait(driver, 10)
login_form = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "input#nom-user")))

login_form.send_keys("a")

Answer 2

而不是＆＃34; .invisibility_of_element_located＆＃34;你可以试试＆＃34; visibility_of_element_located＆＃34;。
