Wie bekomme ich Breiten- und Längengrad von Google Maps v3 api?

Ich versuche, eine Karte mit Google Maps V3 API zu erstellen. Ich habe den folgenden Code über das Internet gefunden und möchte anstelle der Adresse den Breitengrad und die Logitude im Kartenfenster anzeigen.

<script>
      function initialize() {
        var mapOptions = {
          center: new google.maps.LatLng(-33.8688, 151.2195),
          zoom: 13,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById('map_canvas'),
          mapOptions);

        var input = document.getElementById('searchTextField');
        var autocomplete = new google.maps.places.Autocomplete(input);

        autocomplete.bindTo('bounds', map);

        var infowindow = new google.maps.InfoWindow();
        var marker = new google.maps.Marker({
          map: map
        });

        google.maps.event.addListener(autocomplete, 'place_changed', function() {
          infowindow.close();
          marker.setVisible(false);
          input.className = '';
          var place = autocomplete.getPlace();
          if (!place.geometry) {
            // Inform the user that the place was not found and return.
            input.className = 'notfound';
            return;
          }

          // If the place has a geometry, then present it on a map.
          if (place.geometry.viewport) {
            map.fitBounds(place.geometry.viewport);
          } else {
            map.setCenter(place.geometry.location);
            map.setZoom(17);  // Why 17? Because it looks good.
          }
          var image = {
            url: place.icon,
            size: new google.maps.Size(71, 71),
            Origin: new google.maps.Point(0, 0),
            anchor: new google.maps.Point(17, 34),
            scaledSize: new google.maps.Size(35, 35)
          };
          marker.setIcon(image);
          marker.setPosition(place.geometry.location);
          marker.setVisible(true);

          var address = '';
          if (place.address_components) {
            address = [
              (place.address_components[0] && place.address_components[0].short_name || ''),
              (place.address_components[1] && place.address_components[1].short_name || ''),
              (place.address_components[2] && place.address_components[2].short_name || '')
            ].join(' ');
          }

          infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
          infowindow.open(map, marker);
        });

Bitte helfen Sie mir, Breiten- und Längengrade zu erhalten und anzuzeigen. Vielen Dank.

Wo du hast

  var address = '';
  if (place.address_components) {
    address = [
      (place.address_components[0] && place.address_components[0].short_name || ''),
      (place.address_components[1] && place.address_components[1].short_name || ''),
      (place.address_components[2] && place.address_components[2].short_name || '')
    ].join(' ');
  }

  infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
  infowindow.open(map, marker);

Ändern Sie die Infowindow-Zeile zum Lesen

  infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + place.geometry.location.lat() + ',' + place.geometry.location.lng());

Eine viel einfachere Lösung wird sein: 

var address = "New Delhi"
$.ajax({
  url:"http://maps.googleapis.com/maps/api/geocode/json?address="+address+"&sensor=false",
  type: "POST",
  success:function(res){
     console.log(res.results[0].geometry.location.lat);
     console.log(res.results[0].geometry.location.lng);
  }
});

Prost

Sehen Sie sich diesen Code an.

<!DOCTYPE html>
<html>
<head>
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
    <script>
        function initialize() {
        var address = 'Kolkata';
            geocoder = new google.maps.Geocoder();
            geocoder.geocode({
            'address': address
            }, function(results, status) {      
                var lat=document.getElementById("lat").innerHTML=results[0].geometry.location.lat();    
                var lng=document.getElementById("lng").innerHTML=results[0].geometry.location.lng();        
            });
        }
        google.maps.event.addDomListener(window, 'load', initialize);
    </script>
</head>
<body>
    <p id="lat"></p> 
    <p id="lng"></p> 
</body>

Sieht aus, als würden Sie nach regelmäßigem Geolokationsmaterial suchen? Hier ist mein Ausschnitt aus einem Projekt, um die Lat/Long eines Benutzers zu erfassen

auslösen show user location (); um die Geolocation-API zu starten.

function show_user_location(){ 

    navigator.geolocation.getCurrentPosition(display_user_location, error_response); 
} 
function display_user_location(user_position){ 
    var lat = user_position.coords.latitude; 
    var lon = user_position.coords.longitude; 

// once we get here make that AJAX query
// #loc.value="<p>Your latitude is: "+lat+", your longitude is: "+lon+"</p>"+ "<p><a href='http://maps.google.com/?q="+lat+","+lon+"'>View your location on Google Maps</a></p>";

    // I often put the lat/lon in a hidden form for later retrieval here.
    // value = document.getElementById('lat').value;
    // value = document.getElementById('lat').value;

    document.getElementById("lat").value = lat;
    document.getElementById("long").value = lon;

}

Wenn Sie die Breite und Länge eines Teils der Karte festlegen möchten, fügen Sie die Klicklistener für die Karte und nicht die Markierung hinzu. Der Code sollte wie folgt aussehen:

var infowindow = new google.maps.InfoWindow();
    var service = new google.maps.places.PlacesService(map);

    service.getDetails({
        placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4'
    },function(place,status){
        if(status === google.maps.places.PlacesServiceStatus.OK)
        {
            var marker = new google.maps.Marker({
                map:map,
                position: place.geometry.location

            });

        google.maps.event.addListener(map, 'click', function(e) {
          infowindow.setContent('<div>'+'Longitute'+'<strong>' + e.latLng.lng() + '</strong><br>' +
            'Latitude:'+'<strong>' + e.latLng.lat()+'</strong>'  + '</div>');
          infowindow.open(map, this);
        });
        }
    });

Dies zeigt den Breiten- und Längengrad aller Positionen auf der Karte mithilfe eines Infofensters an.
