how do i import javascript executor in python?

[Enrico Bergamini]

So I'm trying to click on multiple like buttons on facebook, which is difficult cause clickable elements are hidden inputs in a form. (full details here) 

I load all the page with the multiple elements then I have 2 paths to find and click like buttons:

buttons =  driver.find_elements_by_tag_name("input")
for element in buttons:
    ActionChains(driver).click(element).perform()

This returns: selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: Offset within element cannot be scrolled into view: (0, 0): [object HTMLInputElement]. 

Probably because the element is invisible

Or I try to inject JS:

driver.execute_script("document.getElementsByClassName('commentable_item').click();");

But it returns that the function document.getElementsByClassName(...).click() is undefined. Why? Should I use any import to make execute_script work?

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import TimeoutException
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
from selenium.webdriver.common.action_chains import ActionChains

You forget that the base method you are executing returns an array, only getElementById() returns singular, all the other document.getXyz methods return plural/array, even if the result is a single result. Therefore, you need to add an index to the call, e.g.

driver.execute_script("document.getElementsByClassName('commentable_item')[0].click();");

if you did want/have multiple elements, you'd have to iterate through that array and click each element:

var elems = document.getElementsByClassName('commentable_item');
for(var i= 0;i<elems.length;i++){
 elems[i].click();
}//and execute this whole block of code with execute_script
