I am using the new Google Maps v3 STYLED MAP.
I want to change how the map is Styled based on the zoom level.
I have the following pseudo-code, how do change my map-style based on the zoom level?
var myOptions = {
zoom: zoom,
center: latlng,
disableDefaultUI: true,
navigationControl: true,
scrollwheel: false,
navigationControlOptions: {style:
google.maps.NavigationControlStyle.SMALL,position:
google.maps.ControlPosition.TOP_RIGHT},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var mapStyleZoomedOut = [{ featureType: "landscape",
elementType: "all",
stylers: [{ visibility: "off" }]
}];
var mapStyleZoomedIn = [{ featureType: "landscape",
elementType: "all",
stylers: [{ visibility: "off" }]
},{
featureType: "poi",
elementType: "all",
stylers: [{ visibility: "off" }]
}];
map = new google.maps.Map(document.getElementById("find-map"),
myOptions);
var styledMapOptions = {map: map};
var styleMapType = new google.maps.StyledMapType(mapStyle,
mapStyleZoomedOut);
map.mapTypes.set('minimial', styleMapType);
map.setMapTypeId('minimial');
google.maps.event.addListener(map, 'zoom_changed', function() {
// === IF Zoom Level <= 8 use mapStyleZoomedIn
// === If Zoom Level > 8 use mapStyleZoomedOut
});
Thanks in advance
Using the Google maps API V3, I put together a test example from your source code (with actual values in order to make the test work).
Below is the code I used to test successfully, the main code to pay attention to is in the start() function.
var myOptions = {
zoom: 7,
center: new google.maps.LatLng(1,1),
disableDefaultUI: true,
navigationControl: true,
scrollwheel: false,
navigationControlOptions: {style: 'SMALL',position: 'TOP_RIGHT'},
mapTypeId: 'ROADMAP'
};
var mapStyleZoomedOut = [{ featureType: "landscape",
elementType: "all",
stylers: [{ visibility: "off" }]
}];
var mapStyleZoomedIn = [{ featureType: "landscape",
elementType: "all",
stylers: [{ visibility: "off" }]
},{
featureType: "poi",
elementType: "all",
stylers: [{ visibility: "off" }]
}];
function start()
{
map = new google.maps.Map(document.getElementById("find-map"), myOptions);
var styledMapOptions = {map: map, name: 'minimial'};
var styledMapOptions2 = {map: map, name: 'maximial'};
var sMapType = new google.maps.StyledMapType(mapStyleZoomedOut,styledMapOptions);
map.mapTypes.set('minimal', sMapType);
map.setMapTypeId('minimal');
var sMapType2 = new google.maps.StyledMapType(mapStyleZoomedIn,styledMapOptions2);
map.mapTypes.set('maximial', sMapType2);
google.maps.event.addListener(map, 'zoom_changed', function()
{
var zoomLevel = map.getZoom();
//DEBUG alert(zoomLevel+', '+map.getMapTypeId());
var sMapType;
// === IF Zoom Level <= 8 use mapStyleZoomedIn
if(zoomLevel <=8)
map.setMapTypeId('maximial');
// === If Zoom Level > 8 use mapStyleZoomedOut
else
map.setMapTypeId('minimal');
});
}
if (window.addEventListener)
window.addEventListener("load", start, false);
else if (window.attachEvent)
window.attachEvent("onload", start);
Simple function that goes to satellite when user is zoomed in, road map when zoomed out
google.maps.event.addListener(map, 'zoom_changed', function() {
if (map.getZoom() >= 15) {
map.setMapTypeId('satellite');
}
else {
map.setMapTypeId('roadmap');
}
});
