How can I invite all my Facebook friends to an event in one go?

The javascript things that kept popping up when I was Googling it (which automatically checks/clicks all your friends) doesn't work on the new Facebook anymore. Help

I created a bookmarklet that will select all friends when clicked. I've posted it here:

All you have to do is drag the link with the text, "FB Select All," to your bookmarks bar. Then, when you have the "Invite Friends" window open, click on the bookmarklet in your bookmarks bar and it will select all friends.

Tested successfully in Chrome and IE.
