Client Side Reverse Geocoding (Google Maps V3 API)

Question

How do you do reverse geocode on a client computer using the Google Maps V3 API? The direct geocode from address to LatLng is direct (code below), but how do you do the same for reverse geocode?

Normal geocode code:

geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK) {
    map.setCenter(results[0].geometry.location);
    var marker = new google.maps.Marker({
    map: map,
    position: results[0].geometry.location
  });

Answer 1

The process is exactly the same, with a slight difference, that instead of providing the address object of the geocoding function, you provide the LatLng object

Reverse Geocode Code:

var input = document.getElementById("latlng").value;
var latlngStr = input.split(",",2);
var lat = parseFloat(latlngStr[0]);
var lng = parseFloat(latlngStr[1]);
var latlng = new google.maps.LatLng(lat, lng);

geocoder.geocode({'latLng': latlng}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK) {
    if (results[1]) {
      map.setZoom(11);
      marker = new google.maps.Marker({
          position: latlng, 
          map: map
      }); 
      infowindow.setContent(results[1].formatted_address);
      infowindow.open(map, marker);
    } else {
      alert("No results found");
    }
  } else {
    alert("Geocoder failed due to: " + status);
  }
});
