Question

Say I have a given a link to a map with a location marker , how can I find the latitude and longitude from that map marker using JavaScript and the Google API?

The trick is that I don’t know the address. Is there a way to find out what the address on the page is elegantly, without having to use regular expressions on the HTML?

Specifically, I want to extract the address and latitude/longitude out of the given marker.

That’s ‘easy’. Google Maps api has a geolocation object, that is the same used by google maps. So you should use something like that:

var geocodeLocation = 'String of the adress you''re looking for';

  var geocoder = new google.maps.ClientGeocoder();
  geocoder.getLatLng(geocodeLocation, function(point) {
    if (point) {
      //Do something with point - //You have point.x and point.y
    }
  });
