Python and Selenium For "execute_script" for "ElementNotVisibleException"
I am using Selenium to save a webpage. The content of the web page will change after clicking certain checkboxes. I want to click a checkbox and then save the page content. (Checkboxes are driven by JavaScript.)
First, I used:
driver.find_element_by_name("keywords_here").click()
it ends up with an error:
NoSuchElementException
then I tried "xpath" like, with implicit / explicit expectation:
URL = "the url"
verificationErrors = []
accept_next_alert = True
aaa = driver.get(URL)
driver.maximize_window()
WebDriverWait(driver, 10)
#driver.find_element_by_xpath(".//*[contains(text(), ' keywords_here')]").click()
#Or:
driver.find_element_by_xpath("//label[contains(text(),' keywords_here')]/../input[@type='checkbox']").click()
it gives error:
ElementNotVisibleException

How do I get Selenium WebDriver to click on an element that is not currently visible?
suppose checkboxes need to be done before clicking, for example using:
execute_script
The question may sound silly, but how can I find the correct sentence for the "execute_script" checkbox visibility from the page source code?
Also, is there any other way?
Thank.
By the way, the html string code looks like this:
<input type="checkbox" onclick="ComponentArt_HandleCheck(this,'p3',11);" name="keywords_here">
its xpath looks like this:
//*[@id="TreeView1_item_11"]/tbody/tr/td[3]/input

An alternative would be to do click()
inside execute_script()
:
# wait for element to become present
wait = WebDriverWait(driver, 10)
checkbox = wait.until(EC.presence_of_element_located((By.NAME, "keywords_here")))
driver.execute_script("arguments[0].click();", checkbox)
where is EC
imported as:
from selenium.webdriver.support import expected_conditions as EC
Alternatively and as another snapshot in the dark, you can use the element_to_be_clickable
Expected Condition and click in the usual way:
wait = WebDriverWait(driver, 10)
checkbox = wait.until(EC.element_to_be_clickable((By.NAME, "keywords_here")))
checkbox.click()

I had problems with expected conditions, I prefer to build my timeout.
import time
from selenium import webdriver
from selenium.common.exceptions import \
NoSuchElementException, \
WebDriverException
from selenium.webdriver.common.by import By
b = webdriver.Firefox()
url = 'the url'
b.get(url)
locator_type = By.XPATH
locator = "//label[contains(text(),' keywords_here')]/../input[@type='checkbox']"
timeout = 10
success = False
wait_until = time.time() + timeout
while wait_until < time.time():
try:
element = b.find_element(locator_type, locator)
assert element.is_displayed()
assert element.is_enabled()
element.click()
success = True
break
except (NoSuchElementException, AssertionError, WebDriverException):
pass
if not success:
error_message = 'Failed to click the thing!'
print(error_message)
may need to add InvalidElementStateException and StaleElementReferenceException
