UPDATE 2: Still a lot of visitors come to my site, so I decided to update the code to a newer one which works as of November 2011. It’s worth to mention that executing Javascript directly in the URL field is not supported for all browsers. It should work in Google Chrome, there is now even an extension for this feature called Facebook Super Select All. Thanks for the contribution in the comments!
UPDATE 1: After this post was originally written, Facebook came up with a solution to create lists of friends. You can create several lists, based on your own personal criterias, and add your friends to different lists, which you then can send event or page invitations to. I would rather recommend using this solution provided by Facebook, so that you don’t send information which might not apply to all of your friends.
To create a list, go to your Account settings, choose Edit Friends and Create new list. After you’ve created new lists you have an option to filter friends based on list names when you’re inviting friends to events or pages.
The newly redesigned Facebook has led inviting members to an event/group/page to an even more complex process. Why can’t they just make a “select all” button? Initially I got tired of clicking several hundred times on all the pictures to invite people to my event, so I came up with this small piece of Javascript:
Go to your event/group/page, click invite people and then paste this snippet in the URL field of your browser.
Left-click the mouse in the URL field and hit Enter. Your invitations will not be sent yet, but all your friends will be selected. Click the “Invite” or “Send” button on the Facebook page to finally send the invites.
Soi! Done in one go

Great information! Thanks for sharing. I saved a lot of time due to your tips.
January 13th, 2012 at 13 January, 2012
it works perfectly, the first thing u must do after clicking invite friends is that u must scroll down on yr friends list to the last one on the page and past the script in the url field, if dont do that its gonna invite about 50 to 100 friends at a time

I savour, result in I found just what I used to be having a look for. You’ve ended my four day lengthy hunt! God Bless you man. Have a great day. Bye

I have used this ingenious script with specific lists and it works well. Scroll to the end of the list first then insert the URL. Unbelievable time saver. Thanks!

Did not work!

I wonder what has happened to the button that used to ‘invite a friend to join fb’? It used to be quite easy to find, now I cannot find it!
Many thanks,
Alma.

I have tried the following article and the code works perfectly :

January 23rd, 2012 at 23 January, 2012
how long does it take to select all my friends? i have about 1,000 and nothing has happened after about ten minutes.
January 25th, 2012 at 25 January, 2012
This is a very nice trick.
But his will only apply to Facebook. How to use this feature if you have a website?
January 26th, 2012 at 26 January, 2012
Thank you SO much for this!!
Question: Why,when I utilize this, it doesn’t select all of my friends (is there a limit on the number of names that can be selected at one time)? And why are some friends still available for selection after I’ve sent them an invitation?
Again, thank you for this great time saver!!

keith, you have to type “javascript:” at the beginning. It doesn’t copy over on its own.
Anyway, thanks for this epic tool. I, too, don’t see why this hasn’t been added as a button in Facebook. You’d think it would be a no-brainer considering the size of most folk’s friends lists.

GRACIAS theeeee Businesssss
February 14th, 2012 at 14 February, 2012
Just to burst your bubble. It still doesn’t work. Facebook has an anti spam detector that allows only a certain amount of invites to be sent. it lets you think you’ve invited all but really only sends between 1-10 invites. I found this out yesterday after a year of wondering why people I know weren’t responding to my invites. I thought I was unpopular. Now after realising this and inviting one at a time once a day i realise I was unpopular!! har har
February 22nd, 2012 at 22 February, 2012
do you have a new javascript.? it doesnt work any more
February 22nd, 2012 at 22 February, 2012
You’re an amazing person… Thankyou so much…
February 23rd, 2012 at 23 February, 2012
i couldn’t get it to work. It kept redirecting to me to a search engine that showed all pages that had to do with selecting all
March 2nd, 2012 at 2 March, 2012
Thank you!! Again – why does FB not have a Select all Friends button??
Unbelievable.

k doesn’t work i tried like 7 times.
March 29th, 2012 at 29 March, 2012
Why didn’t you make a select all button, EH? That would have saved me a button press.
March 29th, 2012 at 29 March, 2012
facebook does not allow you to invite more than 300 people at a time…300 pending is all it handles…so using this code to do groups of more than 300 seems futile. I cant even do more than 300 manually
April 1st, 2012 at 1 April, 2012
its pretty sweet runs 50-100 at a time
thanks you rock
April 1st, 2012 at 1 April, 2012

In chrome you have to go to tools and then javascript console and paste it there… It works..
And a huge thank you to the author of the script..

In Chrome, the “javascript:” disappears. You need to fill it in yourself. Then it works fine!
