{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition,showError);
}
else{x.innerHTML="Geolocationisnotsupportedbythisbrowser.";}
}
functionshowPosition(position)
{
varlatlon=position.coords.latitude+","+position.coords.longitude;
varimg_url="http://maps.googleapis.com/maps/api/staticmap?center="
+latlon+"&zoom=14&size=400x300&sensor=false";
document.getElementById("mapholder").innerHTML="<imgsrc='"+img_url+"'/>";
}
functionshowError(error)
{
switch(error.code)
{
caseerror.PERMISSION_DENIED:
