Javascript: How to get an Object’s ID

In Javascript, one of the most common things you do is document.getElementById(‘someid’).  But what if you got the Element from an Event and you want to use that Object with the Prototype Javascript Library or some other library that relies on using the ID? 

In that case, you can’t just tack on the Prototype functions like:  obj.addClassname(‘someclass’);  You have to use an object that is extended with the Prototype or other library’s magic. 

In Prototype, the easiest way to do that is to get the Object’s ID and use the  $(‘someid’).someFunction(); methodology.  Getting the ID is really simple, though I spent 20 minutes trying to find it on Google.  Here’s how:

  var ID = object.id;

There you go!
