I am working on a project that includes google maps api v3 and PostGres.
What I want to do is to pass the bounding box coordinates(bottom left and top right) of my map window to POSTGRES and get the POI locations for the generated map window on a particular zoom level.
How can I achieve this.. ? Any Ideas? Is there already a direct function for this in api v3?
I've got this on SO but this does not seem to work for me
Finding the lat-long of the corners in a Google Maps window
The question is using the Google Maps API v2, use the Google Maps API v3 equivalent google.maps.Map.getBounds().
The bounds will not be available until the bounds_changed event has fired, so wrap it in a listener for bounds_changed
google.maps.event.addListener(map, "bounds_changed", function() {
// send the new bounds back to your server
alert("map bounds{"+map.getBounds());
});
