Creating an AJAX file upload progress bar in JavaScript

In this video we'll be taking a look at creating an AJAX progress bar for file uploads with JavaScript - it's easy to do by using the "onprogress" event part of XMLHttpRequest. To give it a bit of a special touch we'll also be using a CSS3 transition to make the progress bar animated as the percentage goes up.
