I have a custom map with an information bubble and custom markers. When I zoom into points of interest such as parks and universities appear and when I click an information window opens. How do I disable the info window?
My code is as follows:
var geocoder;
var map;
var infoBubble;
var dropdown = "";
var gmarkers = [];
var hostel_icon = new google.maps.MarkerImage('/resources/hostel_blue_icon.png',
new google.maps.Size(28,32),
new google.maps.Point(0,0),
new google.maps.Point(14,32));
var bar_icon = new google.maps.MarkerImage('/resources/bar_red_icon.png',
new google.maps.Size(28,32),
new google.maps.Point(0,0),
new google.maps.Point(14,32));
var icon_shadow = new google.maps.MarkerImage('/resources/myicon_shadow.png',
new google.maps.Size(45,32),
new google.maps.Point(0,0),
new google.maps.Point(12,32));
var customIcons = {
hostel: {
icon: hostel_icon,
shadow: icon_shadow
},
bar: {
icon: bar_icon,
shadow: icon_shadow
}
};
function initialize() {
var latlng = new google.maps.LatLng(12.82364, 26.29987);
var myMapOptions = {
zoom: 2,
center: latlng,
panControl: false,
scaleControl: true,
mapTypeId: google.maps.MapTypeId.TERRAIN,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR},
navigationControlOptions: {style: google.maps.NavigationControlStyle.DEFAULT}
}
map = new google.maps.Map(document.getElementById("map_canvas"), myMapOptions);
infoBubble = new InfoBubble({
shadowStyle: 0,
padding: 0,
backgroundColor: 'rgb(57,57,57)',
borderRadius: 5,
arrowSize: 10,
borderWidth: 1,
maxWidth: 400,
borderColor: '#2c2c2c',
disableAutoPan: false,
hideCloseButton: true,
arrowPosition: 50,
backgroundClassName: 'phoney',
arrowStyle: 0
});

Simply style the map to not show Points of Interest. This is simple and does not breach Google's terms of service.
eg
You can do this by creating a styled map without labels for the points of interest. This maintains the topography and other nice pieces of information on the map, but removes the markers.
You could consider the following approach to disable POI Info Window:
Example
The above example affects all the info windows, so if you need to disable only POI Info Window, then we could introduce flag to determine whether it is POI Info Window or not:
Example
We can do it by handling clicks on poi, Google api has provided a way to detect clicks on POI as per this article
Based on article above Here is a simpler version of code that can be used to stop the clicks on POI
UPDATE Google Maps JavaScript API V3
You can set clickableIcons to false in MapOptions. This will keep the POI icons but disable the infowindows just as you want.

If you want the data without getting the InfoWindow HTML showing at all, you simply have to re-work the prototype of google.maps.InfoWindow:
