javascript - Close all info windows google maps API V3?

Question

How do i get all info windows to close upon clikcing another pin or clicking the map in itself? I'm using http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobox/docs/reference.html and a kml overlay. heres my JS so far:

jQuery(document).ready(function ($) {
    function initialize() {
        google.maps.visualRefresh = true;
        var myLatlng = new google.maps.LatLng(51.201465, -0.30244);
        var mapOptions = {
            zoom: 12,
            center: myLatlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

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

        var kmlLayer = new google.maps.KmlLayer({
            url: 'http://***.com/new/wp-content/themes/required-starter/CGAGolfAcademies.kml?rand=' + (new Date()).valueOf(),
            suppressInfoWindows: true,
            map: map
        });

        google.maps.event.addListener(kmlLayer, 'click', function (kmlEvent) {
            showInContentWindow(kmlEvent.latLng, kmlEvent.featureData.description);
        });

        function showInContentWindow(position, text) {
            var content = "<div class='info_win'><p>" + text + "</p></div>";
            var infowindow =new InfoBox({
                 content: content,
                 disableAutoPan: false,
                 maxWidth: 0,
                 position: position,
                 pixelOffset: new google.maps.Size(-140, 0),
                 zIndex: null,
                 boxStyle: { 
                  background: "#FBFBFB"
                  ,opacity: 0.90
                  ,width: "280px"
                 },
                 closeBoxMargin: "10px 2px 2px 2px",
                 closeBoxURL: "http://www.google.com/intl/en_us/mapfiles/close.gif",
                 infoBoxClearance: new google.maps.Size(1, 1),
                 isHidden: false,
                 pane: "floatPane",
                 enableEventPropagation: false
        });


    infowindow.open(map);

        }
                    /******AJAX MAP ****/
            siteURL = 'http://' + top.location.host.toString();
            coachesLinks = jQuery('.info_win a');
            coachesLinks.click(function (e) {
                e.preventDefault();
            });
            coachesLinks.click(function (e) {
                alert('FRED');
                $el = jQuery(this);
                URL = $el.attr('href');
                shareurl = $el.attr('href');
                URL = URL + " .main";
                jQuery('#content_two').show('slow').load(URL, function () {
                    scrollToAnchor('content_two');
                    $('.main').css('overflow', 'visible');
                    $('#content_two').css('overflow', 'visible');
                    jQuery('#content_two .back').on('click', function () {
                        jQuery(this).hide('slow');
                        var contentTwo = jQuery('#content_two');
                        if (contentTwo.is(':hidden')) {
                            jQuery('#content_two .back').hide();
                        } else {
                            contentTwo.hide('slow');
                            jQuery('#content > .main').show('slow');
                            jQuery('#content > .main').css('overflow', 'visible');
                            scrollToAnchor('access');
                        }
                    });

                });
                $('#content > .main').hide('slow');
            });

    }

    google.maps.event.addDomListener(window, 'load', initialize);
});

As you see in the API docs, an InfoBox has a close()-method.

Collect all the InfoBox'es you create in an array. Then iterate over this array and call close for each infobox, when you need to close them all at once.

In the top, add an array to hold all the infoboxes created

jQuery(document).ready(function ($) {
    var infoWindows = [];

In function showInContentWindow add the following right after var infowindow=new.., eg just before infowindow.open

//add infowindow to array
infoWindows.push(infowindow); 

add this function

function closeAllInfoWindows() {
  for (var i=0;i<infoWindows.length;i++) {
     infoWindows[i].close();
  }
}

here called by a link

<a href="#" onclick="closeAllInfoWindows();">Close all infowindows</a>
