Question

I am working in google maps and successfully implemented the infobox plugin of google maps.Now my concern is that how can we know that the infobox for a marker is in open state or not. so that I can toggle it on click of the marker…

var locations = [
        //this is array of arrays
    ];

    var map = new google.maps.Map(document.getElementById('map_canvas'),{
        disableDefaultUI : true,
        zoom : 12,
        center : new google.maps.LatLng(defaultLatitude,defaultLongitude),
        mapTypeId : google.maps.MapTypeId.ROADMAP
    });


    var mapcode,myOptions;

    for (var i = 0,len = locations.length; i < len; i++) {
        var marker = add_marker(locations[i][1],locations[i][2],locations[i][3],'this is title',locations[i][0]);
        allMarkers.push(marker);
        marker.setMap(map);
    };

    function add_marker(lat,lng,icn,title,box_html) {

        var marker = new google.maps.Marker({
            animation : google.maps.Animation.DROP,
            position : new google.maps.LatLng(lat,lng),
            map : map,
            icon : icn
        }); 

        mapcode = '<this is the code of infobox to show>';

        myOptions = {
             //options of the infobox...bla bla
        };

        var ib = new InfoBox(myOptions);

        google.maps.event.addListener(marker, 'click', function() {
            ib.open(map, marker);
        });   
        return marker;
    }

I am new in google maps so may be I am missing some very small stuff…thanks in advance….

In case you just need one infobox open at any time you could do it like that:

    var ib = new InfoBox();
    ib.isOpen = false;
    function add_marker(lat,lng,icn,title,box_html) {

    var marker = new google.maps.Marker({
        animation : google.maps.Animation.DROP,
        position : new google.maps.LatLng(lat,lng),
        map : map,
        icon : icn
    }); 

    mapcode = '<this is the code of infobox to show>';

    myOptions = {
         //options of the infobox...bla bla
    };
    marker.ibOptions = myOptions;

    google.maps.event.addListener(marker, 'click', function() {
        ib.setOptions(marker.ibOptions);
        ib.open(map, marker);
        ib.isOpen = true;
    });   
    return marker;
}

If you do it like that you need to reset flag every time you call ib.close() with ib.isOpen = false; (you didn’t specify in what situations do you close the box)

In case you need multiple boxes to be opened:

function add_marker(lat,lng,icn,title,box_html) {

    var marker = new google.maps.Marker({
        animation : google.maps.Animation.DROP,
        position : new google.maps.LatLng(lat,lng),
        map : map,
        icon : icn
    }); 

    mapcode = '<this is the code of infobox to show>';

    myOptions = {
         //options of the infobox...bla bla
    };

    var ib = new InfoBox(myOptions);
    ib.isOpen = false;
    marker.ib = ib;

    google.maps.event.addListener(marker, 'click', function() {
        marker.ib.open(map, marker);
        marker.ib.isOpen = true;
    });   
    return marker;
}

And again if you ever call allMarkers[…].ib.close() you will need to reset the flag with allMarkers[…].ib.isOpen = false;

I hope this helps.
