I am trying Selenium Webdriver to find input element by name and enter a value-CodePudding

I am trying to enter a value in the last box. (Numéro de châssis)

I have tried:

from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from webdriver_manager.chrome import ChromeDriverManager

URL_BASE = "https://www.mobilit.fgov.be/WebdivPub_FR/wmvpstv1_fr?SUBSESSIONID=16382865"
browser = webdriver.Chrome(executable_path=ChromeDriverManager().install())
browser.get(URL_BASE)  
input_1 = WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='Writable3']")))
input_1.send_keys("ABCD")

I got this error

  File ~\anaconda3\lib\site-packages\selenium\webdriver\support\wait.py:90 in until
    raise TimeoutException(message, screen, stacktrace)

TimeoutException

HTML:

<input type="TEXT" autocomplete="off"  name="Writable3" id="Writable3" maxlength="17" style="dir:ltr;   position:absolute; left:416; top:446; width:235; height:22;  ">

CodePudding user response：

Element you trying to access is inside an iframe. You first need to switch to that iframe in order to access elements inside it.
This worked for me:

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('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service, options=options)
url = 'https://www.mobilit.fgov.be/WebdivPub_FR/wmvpstv1_fr?SUBSESSIONID=16382865'
driver.get(url)
wait = WebDriverWait(driver, 20)

wait.until(EC.frame_to_be_available_and_switch_to_it(driver.find_element(By.CSS_SELECTOR, "[name='AppWindow']")))

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='Writable3']"))).click()

When you finished working inside the iframe don't forget to get back to the default content with

driver.switch_to.default_content()
