Get Map Object in Javascript after using CodeIgniter Google Maps API

Question

Hi, I'm using the codeigniter library for the google maps api. I load the map using the library located on the CI Wiki: http://www.phpinsider.com/php/code/GoogleMapAPI/

I want to then use javascript on the map object after loading the page. How can I get the map object in javascript? Can I use GMap2 on the same div? Won't that recreate the map?

The reason I want to do this is to bind an event to the map.

Thanks!
