python selenium驱动程序中的"消息:未知错误:无法聚焦元素"

Question

为什么这段代码会抛出异常selenium.common.exceptions.WebDriverException: Message: unknown error: cannot focus element？

据我所知,我选择了正确的元素.谷歌搜索建议.click()在发送密钥之前有一个on元素,但这也没有帮助.

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()
driver.get("https://netbanking.hdfcbank.com/netbanking/")
login_wait = WebDriverWait(driver, 10)

assert "Welcome to HDFC Bank" in driver.title

frame = login_wait.until(EC.presence_of_element_located((By.NAME, 'login_page')))
driver.switch_to.frame(frame)

try:
    elem = login_wait.until(EC.presence_of_element_located((By.CLASS_NAME, 'pwd_field')))
    print("Page is ready!")
    elem.send_keys("123456")
    elem.send_keys(Keys.RETURN)
except TimeoutException:
    print("Loading took too much time!")

driver.close()

Answer 1

这是因为您通过pwd_field类名span定位的元素- 您实际上已经获得了与定位器匹配的元素.相反,你打算去密码input元素:

elem = login_wait.until(EC.visibility_of_element_located((By.CLASS_NAME, 'input_password')))
