Google Maps: Auto close open InfoWindows?

On my site, I'm using Google Maps API v3 to place house markers on the map.

The InfoWindows stay open unless you explicitly click the close icon. Meaning, you can have 2+ InfoWindows open at a time if you hover over the map marker.

Question: How do I make it so that only the current active InfoWindow is open and all other InfoWindows are closed? Meaning, no more than 1 InfoWindow will be open at a time?

There is a close() function for InfoWindows. Just keep track of the last opened window, and call the close function on it when a new window is created.

My solution.

var map;
var infowindow = new google.maps.InfoWindow();
...
function createMarker(...) {
var marker = new google.maps.Marker({
     ...,
     descrip: infowindowHtmlContent  
});
google.maps.event.addListener(marker, 'click', function() {
    infowindow.setOptions({
        content: this.descrip,
        maxWidth:300
    });
    infowindow.open(map, marker);
});

Declare a variable for active window

var activeInfoWindow;

and bind this code in marker listener

 marker.addListener('click', function () {
    if (activeInfoWindow) { activeInfoWindow.close();}
    infowindow.open(map, marker);
    activeInfoWindow = infowindow;
});

From this link http://www.svennerberg.com/2009/09/google-maps-api-3-infowindows/:

Teo: The easiest way to do this is to just have one instance of the InfoWindow object that you reuse over and over again. That way when you click a new marker the infoWindow is “moved” from where it’s currently at, to point at the new marker.

Use its setContent method to load it with the correct content.

Here is what I used if you are using many markers in a for loop (Django here). You can set an index on each marker and set that index every time you open a window. Closing the previously saved index:

markers = Array();
infoWindows = Array();
var prev_infowindow =false;
{% for obj in objects %}
var contentString = 'your content'
var infowindow = new google.maps.InfoWindow({
            content: contentString,
          });
var marker = new google.maps.Marker({
               position: {lat: {{ obj.lat }}, lng: {{ obj.lon }}},
               map: map,
               title: '{{ obj.name }}',
               infoWindowIndex : {{ forloop.counter0 }}
          });
google.maps.event.addListener(marker, 'click',
            function(event)
            {
           if( prev_infowindow ) {
               infoWindows[prev_infowindow].close();
                }
                prev_infowindow = this.infoWindowIndex;
                infoWindows[this.infoWindowIndex].open(map, this);
            }
        );

        infoWindows.push(infowindow);
        markers.push(marker);

      {% endfor %}
