Closing any open info windows in google maps api v3

Question

As the title states, on a given event (for me this happens to be upon opening a new google.maps.InfoWindow I want to be able to close any other currently open info

Answer 1

I ran into the same problem and fixed it by creating a global info window.

var infowindow = new google.maps.InfoWindow();

Then I have a function to do the following on the click listener:

function getInfoWindowEvent(marker) {
    infowindow.close()
    infowindow.setContent("This is where my HTML content goes.");
    infowindow.open(map, marker);
}

This achieves what I think you're looking for b/c there is now only one info window on the map and I just close it, reload the content and open it again for the given marker.
