Hi,
I'm trying to integrate the Earth plugin into my website. I'd like to
use a <div> with several views (maps, sattelite, terain and earth).
That's easy but I want to add some layers to earth (roads, borders and
buildings). I'm learing with code playgroud where I paste this code:
var map;
var ge;
google.load("maps", "2.x");
function init() {
map = new GMap2(document.getElementById('map3d'));
map.setCenter(new GLatLng(37, -122), 12);
var mapui = map.getDefaultUI();
mapui.maptypes.physical = false;
map.setUI(mapui);
// add 'Earth' as one of the map types
map.addMapType(G_SATELLITE_3D_MAP);
// create a marker
var marker = new GMarker(new GLatLng(37, -122));
GEvent.addListener(marker, "click", function() {
var html = '<div style="width: 210px; padding-right: 10px">Hello
world!</div>';
marker.openInfoWindowHtml(html);
});
map.addOverlay(marker);
google.maps.Event.trigger(marker, "click");
// create a polyline (LineString Placemark in KML)
var polyline = new GPolyline([
new GLatLng(37.04, -122.04),
new GLatLng(37.02, -122.02),
new GLatLng(37.03, -122.01),
new GLatLng(37.01, -121.99)
], "#ff0000", 10);
map.addOverlay(polyline);
// do stuff with Earth when the user switches to it
GEvent.addListener(map, 'maptypechanged', function() {
if (ge)
return;
map.getEarthInstance(function(pluginInstance) {
ge = pluginInstance;
doStuffWithEarth();
});
});
}
function doStuffWithEarth() {
document.getElementById('installed-plugin-version').innerHTML =
ge.getPluginVersion().toString();
ge.getLayerRoot().enableLayerById(ge.LAYER_ROADS, true);
ge.getLayerRoot().enableLayerById(ge.LAYER_BORDERS, true);
ge.getLayerRoot().enableLayerById(ge.LAYER_BUILDINGS, true);
}
All of this is standard "Maps/Earth Integration" except the last 3
lines.
After the map is loaded, i can switch to earth and all layers are
displayed BUT when i switch back to maps and again to earth then the
layers disappear. What's wrong with this code?
