Geocoding using Google API

Question

I used this code to get latitude and longitude. I want to expand to multiple geo-code for multiple locations.

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript">

var geocoder = new google.maps.Geocoder(); var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

 if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
alert(latitude);   }  });  </script>

If I modify to, include two locations. Any ideas why this doesn't write to the webpage, any idea on how to store the latitude and longitude of multiple locations into an array.

See the documentation, address is a string, not an array of arrays of strings.

Note that the geocoder is subject to a quota and rate limit so the code below will only work for approximately 10 results without addressing status=OVER_QUERY_LIMIT.

var geocoder = new google.maps.Geocoder();
var address = [
    ['New York City'],
    ['Chicago, IL']
];
for (var i = 0; i < address.length; i++) {
    geocoder.geocode({
        'address': address[i][0]
    }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            document.getElementById('info').innerHTML += latitude + "<br>";
            document.getElementById('info').innerHTML += longitude + "<br>";
        } else {
            alert("geocode failed:"+status);
        }
    });
}

code snippet:

var geocoder = new google.maps.Geocoder();
var address = [
  ['New York City'],
  ['Chicago, IL']
];
for (var i = 0; i < address.length; i++) {
  geocoder.geocode({
    'address': address[i][0]
  }, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      var latitude = results[0].geometry.location.lat();
      var longitude = results[0].geometry.location.lng();
      document.getElementById('info').innerHTML += latitude + "<br>";
      document.getElementById('info').innerHTML += longitude + "<br>";
    } else {
      alert("geocode failed:" + status);
    }
  });
}
