I'm trying to calculate distance between to addresses
var geocode = function(start, end) {
geocoder.geocode({'address': start}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//In this case it creates a marker, but you can get the lat and lng from the location.LatLng
map.setCenter(results[0].geometry.location);
document.getElementById('startLatlng').value = results[0].geometry.location;
}
});
geocoder.geocode({'address': end}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//In this case it creates a marker, but you can get the lat and lng from the location.LatLng
map.setCenter(results[0].geometry.location);
document.getElementById('endLatlng').value = results[0].geometry.location;
}
});
}
...
...
google.maps.geometry.spherical.computeDistanceBetween(document.getElementById('startLatlng').value, document.getElementById('endLatlng').value) // error
alert(document.getElementById('startLatlng').value) // empty
alert(document.getElementById('endLatlng').value) // empty
I tried also to use callbacks to set a global variable like this
var startl
var endl
var geocode = function(start, end, callback, callback2) {
// ....
callback(results[0].geometry.location)
// ....
callback2(results[0].geometry.location)
}
function setstart(value)
startl = value
function setend(value)
endl = value
....
....
geocode(origin, destination)
alert(startl) // undefined
alert(endl) // undefined
google.maps.geometry.spherical.computeDistanceBetween(startl, endl) // error
the problem i need the both results to compute the distance
i tried to use setTimeout to wait for the async call to be finished like this
....
setTimeout(
google.maps.geometry.spherical.computeDistanceBetween(startl, endl), 3000);
but nothing happened
