Javascript geocoding from address to latitude and longitude numbers not working

rated 0 times [ 33] [ 1] / answers: 1 / hits: 191945 / 13 Years ago, thu, may 12, 2011, 12:00:00

I'm using the following geocoding function to convert a textual address into latitude and longitude numbers, but it's not working right. The alert writes undefined.

Can anyone say what's wrong?

<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.latitude;

    var longitude = results[0].geometry.location.longitude;

    alert(latitude);

    } 

}); 

</script>

Try using this instead:

var latitude = results[0].geometry.location.lat();

var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){

    $(#CreateDialog).find('input[name='+ this.types+']').attr('value', this.long_name);

});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.

If you're only interrested in the whole formated address then you can follow Google's example
