JQuery-ytAPI-Plugin is a project mainly written in JavaScript, it's free.
Simple plugin to get information about videos from YouTube. A friend needed to get descriptions of videos for his web app so I hacked this together.
= YtApi with jQuery
== Install
This JS requires jQuery. In fact, it'd be pretty useless without it. All you need to have some script tag thingies after bringing jQuery into the equation:
<script type="text/javascript" src="js/jquery.yt-api.js"></script>== Usage
index.html has a basic example but you should use the YouTube Data API as a reference since this is just a quick and dirty abstraction over that.
== For the Future
Although this currently relies on jQuery down to the core, I'm thinking of completely removing this dependency. It'd probably be more useful.
