Info Window not closing automatically (Google Maps)

Question

I have created a map http://userpages.flemingc.on.ca/~eluli/example3.html When the layers are turned on, I click on them to see the InfoWindow. As you can see from the link, the InfoWindows do not automatically close when I click on an another layer.

My JavaScript code is as follows. The problem lies in // Pop-up window. I don't have the above issue when I enable this code. However, then the map shows up with all the layers turned on (even though in the legend they are not checked off). This is not something that I want. I want the initial map to have no layers on so that the users themselves can toggle with the layers. And the InfoWindows to close automatically when I click on another layer.

var map, layer2, layers;
layers = [];
function initialize() {
    var ontario = new google.maps.LatLng(49.2867873, -84.7493416);

var mapOptions = {
        zoom: 5,
        center: ontario,
styles: [{"featureType":"landscape.natural","elementType":"geometry.fill","stylers":[{"visibility":"on"},{"color":"#e0efef"}]},{"featureType":"poi","elementType":"geometry.fill","stylers":[{"visibility":"on"},{"hue":"#1900ff"},{"color":"#c0e8e8"}]},{"featureType":"road","elementType":"geometry","stylers":[{"lightness":100},{"visibility":"simplified"}]},{"featureType":"road","elementType":"labels","stylers":[{"visibility":"off"}]},{"featureType":"transit.line","elementType":"geometry","stylers":[{"visibility":"on"},{"lightness":700}]},{"featureType":"water","elementType":"all","stylers":[{"color":"#7dcdcd"}]}]
    }

    var infoWindow = new google.maps.InfoWindow();
    var openInfoWindow = function (KMLevent) {
        infoWindow.close();
        infoWindow.setOptions(
        {
            content: KMLevent.featureData.infoWindowHtml,
            position: KMLevent.latLng,
            pixelOffset: KMLevent.pixelOffset
        });
        infoWindow.open(map);
    };

     map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

    var kmlOptions = {
        suppressInfoWindows: true,  // do not to display an info window when clicked
        preserveViewport: false,
        map: map
    };

Answer 1

To get the infowindows to close when you click on another layer, set suppressInfowindows:true , then add a click listener to each layer that calls your openInfoWindow function. Declare a single global InfoWindow for all the layers to use.

for (var i = 0; i < layers.length; i++) {
    layers[i].setMap(null);
    google.maps.event.addListener(layers[i], "click", openInfoWindow);
}
