I am working with the google maps API and whenever I return the variable to the initialize function from the codeLatLng function it claims undefined. If I print the variable from the codeLatLng it shows up fine.
var geocoder;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(40.730885,-73.997383);
var addr = codeLatLng();
document.write(addr);
}
function codeLatLng() {
var latlng = new google.maps.LatLng(40.730885,-73.997383);
if (geocoder) {
geocoder.geocode({'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
return results[1].formatted_address;
} else {
alert("No results found");
}
} else {
alert("Geocoder failed due to: " + status);
}
});
}
}
prints out undefined
If I do:
var geocoder;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(40.730885,-73.997383);
codeLatLng();
}
function codeLatLng() {
var latlng = new google.maps.LatLng(40.730885,-73.997383);
if (geocoder) {
geocoder.geocode({'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
document.write(results[1].formatted_address);
} else {
alert("No results found");
}
} else {
alert("Geocoder failed due to: " + status);
}
});
}
}
prints out New York, NY 10012, USA
