I am trying to create coordinates based on city with google maps, here is example what i have for now, i always get error?
var address = 'Zurich, Ch';
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var Lat = results[0].geometry.location.lat();
var Lng = results[0].geometry.location.lng();
} else {
alert("Something got wrong " + status);
}
});
var myOptions = {
zoom: 11,
center: new google.maps.LatLng(Lat, Lng),
};
The geocoder is asynchronous. You need to use the returned data in the callback function when/where it is available.

code snippet:
function initialize() {
var address = 'Zurich, Ch';
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var Lat = results[0].geometry.location.lat();
var Lng = results[0].geometry.location.lng();
var myOptions = {
zoom: 11,
center: new google.maps.LatLng(Lat, Lng)
};
var map = new google.maps.Map(
document.getElementById("map_canvas"), myOptions);
} else {
alert("Something got wrong " + status);
}
});
}
google.maps.event.addDomListener(window, "load", initialize);
