In this post I’ll explain how to select all friends on facebook steb-by-step!
It’s very simple and avoids hundreds of clicking on each friend.
Lets start:
- copy this code including semicolon: javascript:elms=document.getElementsByName(“checkableitems[]“);for (i=0;i<elms.length;i++){if (elms[i].type=”checkbox” )elms[i].click()};
- Go to your FB page.
- Click on “Invite Friends”.
- When friends list window appears select “Search All Friends” and scroll down until all friends appear.
- Click on F12 key and choos Console tab.
- Paste copied code in console tab. If there already is other codes paste it on the bottom of them.
- Press Enter key.
- Wait for a while, your browser may freeze for a few minutes, especially if you have many FB friends.
- Enjoy!
all friends Selected!
