Bookmarklet: Select & invite all friends on Facebook

This may be an evil thing, as I hate getting unwanted invites and spam on Facebook... But if you're throwing an event or have created a Facebook "Page", you might want to invite a bunch of people. You probably don't want to have to click each person's name/picture to add them to the invite, so I wrote a little bookmarklet to select them all at once. Simply scroll down to the bottom of your list of friends (it will load more in as you scroll). Once your (no-longer) friends have all loaded, click the bookmarklet to check them all. Here's the original code:

var checks = document.getElementsByClassName('checkableListItem');
for(i=0; i<checks.length; i++){ $(checks[i]).click(); }

And the same code, reformatted for a bookmarklet:

javascript:(function()%7Bvar checks%3Ddocument.getElementsByClassName(%27checkableListItem%27)%3Bfor(i%3D0%3Bi<checks.length%3Bi%2B%2B)%7B%24(checks%5Bi%5D).click()%3B%7D%7D)()%3B

I shall pay for this with spam karma.
