Both Twitter and Facebook have little JavaScript widgets that allow you to share a page using the respective service, displaying a running total of users who have done so. While that’s fine for most purposes, what if you just need the count, for some atypical application?
It’s not well-documented, but the two social media sites have JSON APIs for that purpose.
With a little bit of jQuery magic, you can collect the values on page load and update the DOM with the number. Here’s something I threw together for a project I was working on:
(function() {
var url = 'http://xkcd.com/792/';
jQuery.getJSON("http://urls.api.twitter.com/1/urls/count.json?url="+url+"&callback=?", function(data) {
jQuery('#socialstuff span.twcount').html(data.count);
});
jQuery.getJSON("https://graph.facebook.com/"+url+"&callback=?", function(data) {
jQuery('#socialstuff span.fbcount').html(data.shares);
});
}());
As long as you remember to include jQuery, and have the right HTML elements for the JavaScript to populate, it’s pretty much plug-and-play.
