Function to get Longitude and Latitude from Location using Javascript

Question

My function is like this.

function getLatLong(address){
    var latitude="";
    var geocoder =  new google.maps.Geocoder();

    geocoder.geocode( { 'address': address}, function(results, status) {
        latitude = results[0].geometry.location.lat();
        alert(latitude);
});
   return latitude;
}


  alert(getLatLong(co));

when i call this function I get empty result but the alert in the function returns the latitude.what the problem?

the geocode request is asynchronous, so your return statement can execute before the geocode function completes. See https://developers.google.com/maps/documentation/javascript/geocoding — duncan, May 20 '14 at 10:27

I think the ops answer in this question might help :

Google maps geocode API V3 not returning result in javascript function

As you can see in the solution, the op uses a callback from geocoder.geocode.
