Question

I’m trying to get longitude and latitude values from the google maps api with an address, however it doesn’t seem to be returning any value. Is there a problem with my syntax?

var point = GClientGeocoder.getLatLng('1600 Pennsylvania Avenue NW Washington, DC 20500');
alert(point);

Answer 1

This works (provided you have the correct API key, subject to the 2500 requests/day rate limit):

address_string = '1600 Pennsylvania Avenue NW Washington, DC 20500';
geocoder = new GClientGeocoder();
geocoder.getLatLng(
    address_string,
    function(point) {
        if (point !== null) {
            alert(point); // or do whatever else with it
        } else {
            // error - not found, over limit, etc.
        }
    }
);

You seem to be calling a function of GClientGeocoder, where you need to create a new GClientGeocoder() and call its function.
