Hey, I am using the very cool ym4r tool to get maps and markers on my company website. I need to be able to save a position ( by button click, link, etc ) to update the customer model with a lat and long for position to zoom and init next time they log in. In the google map api, there is a map.getCenter() and i have seen in examples ( not using rails ) of map.getCenter().lat() and map.getCenter().lng() my question is, how can i pass these values to a controller, expecially without a page refresh? thanks for any help shawn
