Selecting several users on Facebook, non-manually?

Is it possible to (perhaps with Firebug) or some other method to select ALL you开发者_C百科r contacts in ONE GO when creating an event on Facebook? How?

You could try the script below:

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

Go to your event page click to invite people then paste this code in the URL bar and hit enter.
