内容图文
我正在尝试使用Selenium自动输入特定网站的用户名和密码.我无法找到要发送密钥的元素.我在下面附上了网站的HTML代码.
这是我目前使用的：
username = driver.find_element_by_id('UserName').getAttribute('value')
此外,网站以.bsd结尾,我并不完全熟悉它,并认为它可能导致问题.
谢谢.

</html>解决方法:
只需使用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.Chrome(executable_path=r'C:\path\To\chromedriver.exe')
driver.get(url)
wait = WebDriverWait(driver, 10)
username = wait.until(EC.presence_of_element_located((By.XPATH, "//input[@id='UserName']")))
# username = driver.find_element_by_xpath("//input[@id='UserName']")
username.send_keys("the useName")
# password = driver.find_element_by_xpath("//input[@id='Password']")
password =wait.until(EC.presence_of_element_located((By.XPATH, "//input[@id='Password']")))
password.send_keys("yourPassword")
希望这对你有所帮助！
