Keep scrolling until Python elements are discovered

My goal is to create a Facebook script that can automatically add all friends from my "Friend List" who are not already on my friend's list. However, the issue arises when there are mutual friends at the top of the list. I need the script to scroll down until it reaches the "Add Friend" button for new connections, and then proceed to click on it.

Since I am new to programming, I would appreciate detailed instructions on how to achieve this task. I understand that Java is typically used for this purpose, but could someone please explain how to implement this in Python?

Below is the initial code snippet:

root.get(targets_url)        #targets_url refers to the link of the target friend list
time.sleep(10)

while True:
    element = root.find_element_by_class_name('FriendRequestAdd').click()

Answer №1

You don't have to use Java for this task as Python will do just fine. If you want to locate the add friends element, you can simply use the find_element_by_id method or any other method available. However, if you are determined to find and scroll to the element.

from selenium.webdriver.ui.support import expected_conditions as ec
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By

wait = WebDriverWait(root)     

root.wait(3) #wait for element to be visible. implicit wait.

#you can change XPATH to CSS_SELECTOR or any other suitable locator
friendlist = wait.until(ec.element_to_be_clickable((By.XPATH,'xpath value'))  #explicitly wait for element to appear on the page
root.execute_script("arguments[0].ScrollIntoView;", friendlist)
friendlist.click()

The purpose of the wait is to ensure that the add friend id loads before Selenium starts looking for it, especially if it doesn't load immediately with the page. If Selenium still cannot find add friend, I would suggest using expected_condition and WebDriverWait, although it's unlikely to come to that

If an explicit wait doesn't work, consider checking if that section of the page is within an iframe or a different frame
