how to get all markers on google-maps-v3

Question

Is there a way to get all the markers on Google Maps?

Answer 1

If you mean "how can I get a reference to all markers on a given map" - then I think the answer is "Sorry, you have to do it yourself". I don't think there is any handy "maps.getMarkers()" type function: you have to keep your own references as the points are created:

var allMarkers = [];
....
// Create some markers
for(var i = 0; i < 10; i++) {
    var marker = new google.maps.Marker({...});
    allMarkers.push(marker);
}
...

Then you can loop over the allMarkers array to and do whatever you need to do.

Answer 2

The one way found is to use the geoXML3 library which is suitable for usage along with KML processor Version 3 of the Google Maps JavaScript API.
