taking attribute (zip code) and using it in Google maps API 3

i have a magento site where my products are businesses. I want to add a google map to the product page and need someone to help me with my code.

I can call the zip code by typing

<?php echo $_product->getpostcode() ?>

I have taken code from the internet and am trying to put it together for my site. here is the code:

  <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>

   <script>
  var geocoder;
  var map;
  var address = '<?php echo $_product->getpostcode() ?>'
  function initialize() {
    geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var mapOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
  }

  function codeAddress() {
    var address = document.getElementById('address').value;
    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
        });
      } else {
        alert('Geocode was not successful for the following reason: ' + status);
      }
    });
      }
    </script>
    <body onload="initialize()">

    <div id="map_canvas" style="width: 500px; height: 300px"></div>

At the moment it is using the lat long in the code. How can i change it to using the zip code?`

//i have working function use it.
  function initialize() {
var address = "<?php echo $address?>";
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(50.317408,11.12915);
var myOptions = {
  zoom: 8,
  center: latlng,
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("location-canvas"), myOptions);
if (geocoder) {
  geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      if (status != google.maps.GeocoderStatus.ZERO_RESULTS) {
      map.setCenter(results[0].geometry.location);

        var infowindow = new google.maps.InfoWindow(
            { content: '<b>'+address+'</b>',
              size: new google.maps.Size(150,50)
            });

        var marker = new google.maps.Marker({
            position: results[0].geometry.location,
            map: map, 
            title:address
        }); 
        google.maps.event.addListener(marker, 'click', function() {
            infowindow.open(map,marker);
        });

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

}

Maps always use co-ordinates. That how maps work. If you want to use a zipcode, you need to convert that to co-ordinates — that process is called geocoding.

You have a geocoding function in your code, which won't work at the moment because you don't have an element called address, but it can be used with a little adjustment.

You currently have a global variable called address, which contains your zipcode, so get your geocoder function to use it:

At the bottom of function initialize(), add a call to the geocoder function, passing it the global variable:

 map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
 codeAddress(address);
}

Change that function to accept a parameter:

function codeAddress(addy) {

and then to use it:

// var address = document.getElementById('address').value;
// The above line needs to be removed; the one below amended
geocoder.geocode( { 'address': addy}, function(results, status) {
