[selenium-users] 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

)
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

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
