Google Maps Map Movement


#1

Hi everyone,

I need help with RoR and Google Maps. Here is my dilemma. Say
coordinates are being fed into a db. I would like to create a page that
gets those coordinates say every 5 seconds and moves a marker on a
Google Map. I do not want to refresh the page. Maybe AJAX? I’m not
sure. Has anyone ever done this? Any help would be greatly appreciated.

You’ll want to use Prototypes PeriodicalExecuter function to
periodically call more data from Ruby and execute a function in your
javascript.
Check the API for Prototype:
