Chrome driver not finding ID nor replacing them, what am I doing wrong?-CodePudding

I am trying to build my first python selenium bot that checks me into southwest automatically. I've got the code to open southwests' check-in site, but it doesn't type anything. Can anyone tell me what I am doing wrong?

from selenium import webdriver

driver = webdriver.Chrome('/Users/thomas****/chromedriver/chromedriver')

driver.get('https://www.southwest.com/air/check-in/index.html')

conf_num = driver.find_element_by_id("confirmationNumber")
first_name = driver.find_element_by_id("passengerFirstName")
last_name = driver.find_element_by_id("passengerLastName")

conf_num.send_keys("1234")
first_name.send_keys("Thomas")
last_name.send_keys("****")

submit = driver.find_element_by_id('form-mixin--submit-button')
submit.click()

CodePudding user response：

I just checked, it is working. Your only issue is that '1234' is not a valid confirmation number. Look closely and it shows Enter valid confirmation #. under the Confirmation # field.

Replace it with something like the following, for example, and you will see a bigger error.

conf_num.send_keys("977089")

CodePudding user response：

I use don't use the function find_element_by_id(). Try using By.

conf_num = driver.find_element(By.ID, "confirmationNumber")
first_name = driver.find_element(By.ID, "passengerFirstName")
last_name = driver.find_element(By.ID, "passengerLastName")
... 
submit = driver.find_element(By.ID, 'form-mixin--submit-button')

Note that you have to import:

from selenium.webdriver.common.by import By

CodePudding user response：

Looks like you are missing a delay. You need to wait for elements to be loaded and be ready to accept inputs. WebDriverWait is used for that. Also, all the find_element_by_* are obsolete now. New syntax should be used instead as following:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

options = Options()
options.add_argument("start-maximized")

webdriver_service = Service('/Users/thomas****/chromedriver/chromedriver')
driver = webdriver.Chrome(options=options, service=webdriver_service)
wait = WebDriverWait(driver, 20)

url = "https://www.southwest.com/air/check-in/index.html"

driver.get(url)

wait.until(EC.element_to_be_clickable((By.ID, "confirmationNumber"))).send_keys("1234")
wait.until(EC.element_to_be_clickable((By.ID, "passengerFirstName"))).send_keys("Thomas")
wait.until(EC.element_to_be_clickable((By.ID, "passengerLastName"))).send_keys("****")
wait.until(EC.element_to_be_clickable((By.ID, "form-mixin--submit-button"))).click()
