The data originates in a database but is served to the script through an AJAX call that returns JSON. Then I simply loop through the JSON object and pass the type to the icons array like this.

for(var i = 0; i < json.length; i++) {
    var point = new GLatLng(json[i].Latitude, json[i].Longitude);
    var marker = new GMarker(point, { icon: myIcons[json[i].Type]});
    // Do some more stuff to add the marker to the map
}

My question was in your posting you said you use

var marker = new GMarker(point, { icon: myIcons[type]});

instead of

var marker = new GMarker(point, { icon: myIcons['house']});

I would like to know how you are passing the ‘house’ variable to ‘type’. Are you grabbing it from a database, xml or some other way.

var marker = new GMarker(point, { icon: myIcons[type]});

I have a column in my database that labels (e.g. 1 , 2, 3 ) locations. How do I pass that label to the type variable?

Thanks in advance.
