Invite All Friends to an Event on Facebook

It is possible to invite all friends to an event on facebook with this procedure. I've prepared a video to help you through the process. See below the video for the cut and paste code that you'll need.

Here's the code that as of 2012 works:
-----------cut------------
javascript:(function(){elms=document.getElementsByName("checkableitems[]");for(i=0;i<elms.length;i++){if(elms[i].type="checkbox"){elms[i].checked=true;if(elms[i].parentNode.className.indexOf("disabledCheckable")<0){elms[i].click();elms[i].parentNode.className+=" selectedCheckable";}}};})();


--------------cut---------
