How to access javascript result in selenium

Question

I use below code to execute javascript, and it works well.

from selenium import webdriver driver=webdriver.Firefox() driver.get("https:example.com") driver.execute_script('isLogin()') 

But when I try to access the result return by isLogin() with

isLogin = driver.execute_script('isLogin()') print(isLogin) # always None 

Answer 1

You need to return the value returned by isLogin()

isLogin = driver.execute_script('return isLogin();')
