Hi Rossko:
acctually I make my code more simple :
Javascript code :
var latlngArray = null;
var ThisCarDeviceId = null;
var AutoScaleFlagBool = null;
function load(y, x) {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(x, y), 17);
map.setMapType(G_HYBRID_MAP);
map.addControl(new GSmallMapControl());
map.addControl(new GScaleControl());
map.addControl(new GMapTypeControl());
map.addControl(new GOverviewMapControl());
var ppgicon = new new GIcon(G_DEFAULT_ICON);
ppgicon.src = strimg;
ppgicon.iconSize = new GSize(24, 24);
ppgicon.iconAnchor = new GPoint(12, 12);
ppgicon.infoWindowAnchor = new GPoint(0, 24);
ppgicon.transparent = null;
ppgicon.imageMap = null;
var latlng = new GLatLng(y, x);
if (!isDefined(latlngArray)) {
latlngArray = new Array();
}
latlngArray.push(latlng);
if (isDefined(ThisCarDeviceId))
if (ThisCarDeviceId == deviceid) {
DESTINATION_MARKER = new GMarker(latlng, ppgicon);
map.addOverlay(DESTINATION_MARKER);
}
}
