Selenium 无法以任何方式找到元素

Question

I am trying to fill out a login form with python code. For that I need to click submit as the last step.

But Selenium can't find the submit button, wether by ID, Class, CSS Selector or Name.

Here is my full code

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
import time

website_link = "https://wildfall.net/wp-admin/"
username = "xxxx"
password = "xxxx"

element_for_username = "user_login"
element_for_password = "user_pass"
element_for_submit = "wp-submit"

browser = webdriver.Chrome()
browser.get((website_link))

time.sleep(5)

username_element = browser.find_element(By.ID, element_for_username)
username_element.send_keys(username)
password_element = browser.find_element(By.ID, element_for_password)
password_element.send_keys(password)
WebDriverWait(browser, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name^='a-'][src^='https://www.google.com/recaptcha/api2/anchor?']")))
WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='recaptcha-checkbox goog-inline-block recaptcha-checkbox-unchecked rc-anchor-checkbox']/div[@class='recaptcha-checkbox-border']"))).click()
time.sleep(10)
submit_element = browser.find_element(By.ID, element_for_submit)
submit_element.click()

Part where the error occurs

submit_element = browser.find_element(By.ID, element_for_submit)
submit_element.click()

Here is the error

>>> submit_element = browser.find_element(By.ID, element_for_submit)
Traceback (most recent call last):

I don't understand why it can't find the button, as it finds all others. It's also no iframe so can't be because of that. Maybe I just don't find the correct Name/Class/ID for the Button but there's not much to choose from, so I'm lost at this point.

Answer 1

You switched to the iframe, you have to switch back. Try using:

driver.switch_to.default_content()

Answer 2

As @facuew correctly pointed out, once you click on the reCAPTCHA checkbox , to click on the element Anmelden you have to switch to the default content.

Your optimized code block can be:

driver.get('https://wildfall.net/wp-admin/')
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#user_login"))).send_keys("username@stackoverflow.com")
driver.find_element(By.CSS_SELECTOR, "input#user_pass").send_keys("simplyGamic")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title=reCAPTCHA]")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.recaptcha-checkbox-border"))).click()
driver.switch_to.default_content()
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#wp-submit"))).click()
