How to invite all your Facebook friends at Once

In the last few days, Facebook has changed the “invite your friends” functionality, which powers suggestions and invitations to events, groups, pages, etc.
The result is that old Javascript codes that allowed you to invite ALL your Facebook friends to an event in a snap (such as this) are now broken.
To select all your new friends in the new interface you can use this code, tested under Safari 5.0.4, Chrome 10 and Firefox 4 (should work also under IE).
UPDATE: There are many reports of it working on newer versions in the comments below


.
javascript:var x=document.getElementsByTagName("input");for(var i=0;i<x.length;i++) {if (x[i].type == 'checkbox') {x[i].click();}}; alert('Done, all your friends have been selected');

In order to use this code, copy and paste it in the address bar of your browser after you have opened the “invite your friends” dialog and AFTER YOU HAVE SCROLLED DOWN THE LIST.
Important note: as said, you HAVE to scroll down your friends list in order to invite all your friends: in fact the new interface only loads few friends via AJAX at a given time.
Facebook should definitely be a little more open regarding MY data, loaded on their systems… and this script opens it just a bit more.
