Setting Style of Css in python

Question

This is my Code (without imports and stuff):

driver.get('http://democaptcha.com/demo-form-eng/hcaptcha.html')
time.sleep(3)
driver.execute_script("document.getElementsByName('h-captcha-response').style.display='none';")

But this throws me the error:

selenium.common.exceptions.JavascriptException: Message: javascript error: Cannot set property 'display' of undefined

when i do:

driver.execute_script("document.getElementById('h-captcha-response-0zu3aawejggj').style.display = 'block';")

it shows me the error

selenium.common.exceptions.JavascriptException: Message: javascript error: Cannot read property 'style' of null

(code is referenced to)

Selenium (with python) how to modify an element css style

How can I change/remove style attibute with selenium python?

THANKS!

getElementsByName returns an array of elements, not one element. You can't do getElementsByName().style. An array has no .style property. — Jeremy Thille

It's because it can't find the element. Probably because the ID keeps changing every page load. Another option could be

driver.execute_script("document.querySelector(`[id^='h-captcha-response']`).style.display = 'block'");

It means that it will find the first element with an ID that starts with h-captcha-response.

Try this:

driver.execute_script("document.getElementsByName('h-captcha-response')[0].style.display = 'block';")
