Unable to locate checkbox Selenium

Question

i am trying to make my selenium script select the "selectALL" checkbox on a website. The trouble is the python program cannot find it

I have tried

Using name
Using xpath

Results are as follows.

With name:

checkButton = driver.find_element_by_name("checkALL")
checkButton.click()

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[name="checkALL"]"}
  (Session info: chrome=80.0.3987.132)

With xpath:

checkButton = driver.find_element_by_xpath("//table[@id='tbl2']/tbody/tr/td/input")
checkButton.click()

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//table[@id='tbl2']/tbody/tr/td/input"}
  (Session info: chrome=80.0.3987.132)

Google Chrome element dump:

<input type="checkbox" name="checkALL" rownumber="" value="notchecked" onclick="checkAllCheckedRows('portID')">

I'm very confused as to why this is not working. I even have a 5 second delay between actions.

Full Code

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from webdriver_manager.chrome import ChromeDriverManager
import time
from selenium.webdriver.support.ui import Select

driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("http://192.168.1.235/login.cgi")
assert "NETGEAR ProSAFE Plus Switch" in driver.title
#Locate Password
passwordInput = driver.find_element_by_id("password")
#Input switch password
passwordInput.clear()
passwordInput.send_keys("password")
passwordInput.send_keys(Keys.RETURN)
#Wait for mainpage to load
time.sleep(5)
#Switch to Port Status
portStatusButton = driver.find_elements_by_xpath('//*[@id="blueLinkBold11"]/div[2]/a')
print(portStatusButton)
portStatusButton[0].click()
time.sleep(5)
#Check select all checkbox
checkButton = driver.find_element_by_name("checkALL")
checkButton.click()
#Select option from Menu (Disable)
speedDropdown = Select(driver.find_element_by_name("SPEED"))
speedDropdown.select_by_value(2)
#Click Apply Button
applyButton = driver.find_element_by_name("btn_Apply")
applyButton.click()
driver.close()

Make sure you wait until the page is loaded and element is displayed. And also check if the element is present in the iframe. — supputuri, Mar 16 '20 at 15:50
@supputuri it certainly has loaded and displayed. Still it does not work — Lyra Orwell, Mar 16 '20 at 16:05
Were you able to find the element with `[name='checkALL']` in the chrome devtools? — supputuri, Mar 16 '20 at 16:18
now check `[name='checkALL']/ancestor::html`. If it's pointing to the browser html then you don't have any iframe wrapping the element but if you see `document#` as parent of the html element then get the iframe and switch to it. — supputuri, Mar 16 '20 at 16:57
I don't see document# I see [name='checkALL']/ancestor::html — Lyra Orwell, Mar 16 '20 at 17:01

You have to switch to the right iframe before interacting with the element.

driver.switch_to.frame(driver.find_element_by_css_selector(css_selector))
# then click on the element.
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='checkALL']"))).click()

To click on the element you have to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

Using CSS_SELECTOR:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='checkALL'][value='notchecked'][onclick^='checkAllCheckedRows']"))).click()

Using XPATH:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='checkALL' and @value='notchecked'][starts-with(@onclick, 'checkAllCheckedRows')]"))).click()

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

I get a raise TimeoutException(message, screen, stacktrace) error — Lyra Orwell, Mar 16 '20 at 16:54
