how to make map updatabe?

[jeltz]

Hi,
I have an application to collect telemetry data from geographically distributed sensors and to visualize status in Google Map.
E.g., presently my app outputs Google map API 3 html/java script into the local folder.
 Presently, the application just overwrites output html with the new html/javascript whenever something in sensor status is changed
I am using java script timer to re- load the page periodically, but it seems as new html is never loaded.
What would be the simplest approach to update google map "on demand" ?
Thanks,
-V

AJAX (Asynchronous Javascript And Xml [or JSON])

Use a cache busting argument in the URL to prevent the browser from
caching it.

I thought AJAX can get data from server without reloading page. How does that can help? I need to reload page when content is changed on server.

My point was that you don't need to reload the page when the data on
the server changes. But maybe I misunderstood your requirement.
