How to locate the username and password element through Selenium WebDriver and Python

 原文  2019-01-07 15:49:22  0   2    python/ selenium/ xpath/ css-selectors/ webdriverwait

Question

I am attempting to automatically enter my username and password for a particular website with Selenium. I am having trouble finding the element to send the keys to. I have attached the website's HTML code below.

Here is what I am currently using: 

username = driver.find_element_by_id('UserName').getAttribute('value')

Additionally, the website ends in a .bsd which I am not entirely familiar with and think that it could be contributing to the problem.

Thanks.

Just use 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")

Hope this helps you!

To send character sequence to the username and password field in the particular website as the elements are within a <frame> you have to:

  • Induce WebDriverWait for the desired frame to be available and switch to it .
  • Induce WebDriverWait for the desired element to be clickable .

  • You can use either of the following solutions:

    • Using CSS_SELECTOR : 

       WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"frame[name='MainWin'][src^='Logon.bsd?Lang=English']"))) WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "label[for='UserName']"))).send_keys("Its_code_outside") driver.find_element_by_css_selector("label[for='Password']").send_keys("Its_code_outside")

    • Using XPATH : 

       WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//frame[@name='MainWin' and starts-with(@src, 'Logon.bsd?Lang=English')]"))) WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@for='UserName']"))).send_keys("Its_code_outside") driver.find_element_by_xpath("//label[@for='Password']").send_keys("Its_code_outside")

  • Note : You have to add the following imports : 

     from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
