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.

JavaScript: Use the goo.gl link shortener from your own site

Here's a quick, stripped-down version of a javascript implementation of the goo.gl link-shortener service. It asynchronously loads the Google client API, then uses another callback when the link shortener service is loaded. After the service loads, you can call shortenUrl() as many times as you'd like. For simplicity, I've only shortened one URL here. It doesn't appear that you need an API key to simply shorten URLs, but certain calls to this service would require one. Here's the basic version, which should work in modern browsers.

var shortenUrl = function() {
  var request = gapi.client.urlshortener.url.insert({
    resource: {
      longUrl: 'http://plasticsoundsupply.com'
    }
  });
  request.execute(function(response) {
    var shortUrl = response.id;
    console.log('short url:', shortUrl);
  });
};

var googleApiLoaded = function() {
  // gapi.client.setApiKey("YOUR API KEY")
  gapi.client.load("urlshortener", "v1", shortenUrl);
};

window.googleApiLoaded = googleApiLoaded;
$(document.body).append('<script src="https://apis.google.com/js/client.js?onload=googleApiLoaded"></script>');
