Have just one InfoWindow open in Google Maps API v3

Question

I need to have only one InfoWindow open on my Google Map. I need to close all other InfoWindows before I open a new one.

Can someone show me how to do this?

Answer 1

Create your infowindow out of the scope so that you can share it.

Here is a simple example:

var markers = [AnArrayOfMarkers];
var infowindow = new google.maps.InfoWindow();

for (var i = 0, marker; marker = markers[i]; i++) {
  google.maps.event.addListener(marker, 'click', function(e) {
    infowindow.setContent('Marker position: ' + this.getPosition());
    infowindow.open(map, this);
  });
}
