Google Maps API，如何从机场代码获取时间？

Question

I wonder how to get the LAT and LONG from an airport. For example I have the airport code "CPH" (Copenhagen) and I need to draw a line from my marker to that point. Right now my code for the line is this:

        var flightPlanCoordinates = [
        new google.maps.LatLng(event.latLng.lat(), event.latLng.lng()),
        new google.maps.LatLng(21.291982, -157.821856)
    ];
    flightPath = new google.maps.Polyline({
        path: flightPlanCoordinates,
        geodesic: true,
        strokeColor: '#FF0000',
        strokeOpacity: 1.0,
        strokeWeight: 1
    });

    flightPath.setMap(map);

But I need the line to go the the airport. I've looked at the geocoding but I don't understand on how to use it with an airport. Can someone do a example for me? Thank you! :)

Use the geocoder, it supports the "CPH" abbreviation (you might want to make it "CPH airport" to be safe).

geocoder.geocode( { 'address': "CPH airport"}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK) {
    CPH = results[0].geometry.location;
    bounds.extend(CPH);
    var marker = new google.maps.Marker({
      map: map,
      position: results[0].geometry.location
    });
  } else {
    alert('Geocode was not successful for the following reason: ' + status);
  }
});

code snippet:

 var geocoder = new google.maps.Geocoder(); var map; var CPH; var bounds = new google.maps.LatLngBounds(); function initialize() { map = new google.maps.Map( document.getElementById("map_canvas"), { center: new google.maps.LatLng(37.4419, -122.1419), zoom: 13, mapTypeId: google.maps.MapTypeId.ROADMAP }); geocoder.geocode({ 'address': "CPH airport" }, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { CPH = results[0].geometry.location; bounds.extend(CPH); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert('Geocode was not successful for the following reason: ' + status); } }); google.maps.event.addListener(map, 'click', function(event) { var flightPlanCoordinates = [ event.latLng, CPH ]; bounds.extend(event.latLng); flightPath = new google.maps.Polyline({ path: flightPlanCoordinates, geodesic: true, strokeColor: '#FF0000', strokeOpacity: 1.0, strokeWeight: 1 }); map.fitBounds(bounds); flightPath.setMap(map); }); } google.maps.event.addDomListener(window, "load", initialize);
