Answer 1

Solution:
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
function initialize() {
var loc = {};
var geocoder = new google.maps.Geocoder();
if(google.loader.ClientLocation) {
loc.lat = google.loader.ClientLocation.latitude;
loc.lng = google.loader.ClientLocation.longitude;
var latlng = new google.maps.LatLng(loc.lat, loc.lng);
geocoder.geocode({'latLng': latlng}, function(results, status) {
if(status == google.maps.GeocoderStatus.OK) {
alert(results[0]['formatted_address']);
};
});
}
}
google.load("maps", "3.x", {other_params: "sensor=false", callback:initialize});

Answer 2

google.loader.ClientLocation only gives a very approximate estimate as to the user's location.
Best choice is to use that as a fallback if HTML5 geolocation is not present, or not allowed by the user.
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(
function(p) {
//get position from p.coords.latitude and p.coords.longitude
},
function() {
//denied or error
//use google.loader.ClientLocation
}
);
} else {
//use google.loader.ClientLocation
}

jQuery('#map_canvas').gmap({ 'zoom':2,'center':new google.maps.LatLng(39.809734,-98.55562), 'callback': function() {
var self = this;
self.getCurrentPosition(function(position, status) {
if ( status === 'OK' ) {
clientlat = position.coords.latitude;
clientlon = position.coords.longitude;
var clientlatlng = new google.maps.LatLng(clientlat, clientlon);
}
});
}});
