[Google Maps API v3] Re: google map api v3 reverse geocoding not working ?

[mark]

I have eventually got this working, baring in mind that im a complete 
javascript beginner how does my code look. Are there any errors or anything 
i should be worried about ?

Example link is the same http://rayoflightes.com/gmaps/form1.php

var geocoder = new google.maps.Geocoder();

function geocodePosition(pos) {
  geocoder.geocode({
    latLng: pos
  }, function(responses) {
    if (responses && responses.length > 0) {
      updateMarkerAddress(responses[0].formatted_address);
    } else {
      updateMarkerAddress('Cannot determine address at this location.');
    }
  });
}

function updateMarkerStatus(str) {
  document.getElementById('markerStatus').innerHTML = str;
}

function updateMarkerPosition(latLng) {
  document.getElementById('latitude').value = [
    latLng.lat()
  ];
  document.getElementById('longitude').value = [
    latLng.lng()
  ];
}



function initialize() {

          var address = document.getElementById("address").value;

  var latLng = new google.maps.LatLng(-34.397, 150.644);
  var map = new google.maps.Map(document.getElementById('mapCanvas'), {
    zoom: 12,
    center: latLng,
    mapTypeId: google.maps.MapTypeId.SATELLITE
  });
    
    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,
            draggable: true,
            position: results[0].geometry.location,
        });

    map.setZoom(18);

  // Update current position info.
  updateMarkerPosition(latLng);
  geocodePosition(latLng);
  
  // Add dragging event listeners.
  google.maps.event.addListener(marker, 'dragstart', function() {
    updateMarkerAddress('Dragging...');
  });
  
  google.maps.event.addListener(marker, 'drag', function() {
    updateMarkerStatus('Dragging...');
    updateMarkerPosition(marker.getPosition());
  });
  
  google.maps.event.addListener(marker, 'dragend', function() {
    updateMarkerStatus('Drag ended');
    geocodePosition(marker.getPosition());
  });
    
    /* When geocoding "fails", see if it was because of over quota error: */
            } else if (status == 
google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
              wait = true;
              setTimeout("wait = false", 1000);

            } else {
              alert("Geocode was not successful for the following reason: " 
+ status);
            }
    });
  

}

// Onload handler to fire off the app.
google.maps.event.addDomListener(window, 'load', initialize);
