Facebook Select All Code for Events and Fanpages

Steps on how to use the script:

1. Go to the FB Events or Fanpage that you have
2. Go to the Select Friends Dialog (the one with the many checkboxes) (Be sure to select all of your friends and not only the friends you have recently interacted with (Recent Interactions Tab) if you wish to select "all of your friends")
3. Scroll down to the very bottom of the list (this is important since if you don't not all of your friends would get selected)
4. Open the Console (Ctrl-Shift-J [Chrome] or Ctrl-Shift-K [Firefox]
5. Paste the code above
6. Hit Enter
7. Wait for a few seconds or minutes (if you have long list of friends).
8. Solve the captcha if it shows up.
