我正试图在CC的登录页面中输入用户名(和密码(。
然而，Selenium给了我一个错误：
"selenium.com.mon.exceptions.NoSuchElementException：消息：无法定位元素：[id="username"]"。
在尝试识别用户名id之前，我让页面加载了5秒钟，但这没有帮助。我还尝试过用xpath和name进行识别，但没有成功。有人知道可能出了什么问题吗？
这是我要登录的CC网页。
到目前为止，这是我的代码：
def login(url, usernameId, username, passwordId, password, submit_buttonId):
driver.get(url)
time.sleep(5)
driver.find_element_by_id(usernameId).send_keys(username) #username input box not being identified
driver.find_element_by_id(passwordId).send_keys(password)
driver.find_element_by_xpath(submit_buttonId).click()
login(
'https://cards.barclaycardus.com/',
'username', myBarclaysUsername,
'password', myBarclaysPassword,
'loginButton'
)
<iframe id="login-iframe" title="Login" src="https://www.barclaycardus.com/servicing/authenticate/home?rnd=120231985&xsessionid=FF4CC3BDD157751E5B9AF5E756D3E303" frameborder="0"></iframe>
你有一个iframe开关。
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID, "login-iframe")))
导入
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
这是一个iframe，所以你必须切换到它
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
def login(url, usernameId, username, passwordId, password, submit_buttonId):
driver.get(url)
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID, "login-iframe")))
time.sleep(5)
driver.find_element_by_id(usernameId).send_keys(username) #username input box not being identified
driver.find_element_by_id(passwordId).send_keys(password)
driver.find_element_by_xpath(submit_buttonId).click()
login(
'https://cards.barclaycardus.com/',
'username', myBarclaysUsername,
'password', myBarclaysPassword,
'loginButton'
)
您尝试过wait.until吗？看看这样的东西是否有效：
from selenium import webdriver
from selenium.webdriver.support import ui
driver = webdriver.Chrome()
driver.get(url)
wait.until(lambda driver: driver.find_element_by_id('username'))
