facebook invite all script

This is really a powerful tool, because clicking every friends one by one is a really tedious job.
1.In Mozilla Firefox, go to your Event, Group or page and click “Invite People”.

2.Once the page has loaded you should see all of your friends, but they are not selected.

3.At this point, copy and paste the java script code below into your Web browser’s address bar, then hit “Enter”.

javascript:elms=document.getElementById(‘friends’).getElementsByTagName(‘li’);for(var fid in elms){if(typeof elms[fid] === ‘object’){fs.click(elms[fid]);}}

OR

javascript:fs.select_all();return false;  

4.If all goes well, it selects all of your friends! Now Click Send Invitations, and you’re done!

Easy as that, and it just took 1 second to invite all your friends. Wow!

I had test this JavaScript with Google Chrome and it works.
