Variable "marker" is responsible for mark place on map. Now I must to enter coordinates.
I need mark city, but name of the city, no coordinates.
Look into the geocoding API: http://code.google.com/intl/sv-SE/apis/maps/documentation/geocoding/.

I've got a great map with the circle overlay but now I want to add the functionality to geocode an address and show it on the same map to see if the address falls within the cicle.

The above code works great. I just can't get the extra geocoded part done.
Use the google maps api geocode service like this:
var geocoder = new google.maps.Geocoder();
function geocode(address) {
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
});
}
geocode("Wilhelminastraat 109HS")
This will find the latitude and longitude of your address and mark it on the map.

Im triying to create a map with a marker from a position taken from a database. I succeed creating the map using this tutorial. The problem is that i have to enter manually the center position when i create the map.
¿Is there a way to center the map using the marker?. The code that im using is the following:

Thanks a lot!
I used this in an app after adding the marker. Might help you.
bounds = new google.maps.LatLngBounds();
bounds.extend(marker.position);
if (!bounds.isEmpty())
map.panTo(bounds.getCenter());
Original idea was to find the center of a bunch of markers, so this might be overkill.
I've followed the search and zoom example from here: https://developers.google.com/fusiontables/docs/samples/search_and_zoom
and I've managed to get the "Reset" button to work, but the "Search" button isn't working. I wondered if it was because I am using 2 layers, but I don't know how to correct by java script if that is that case. Any help appreciated. Thanks.

I get a "geocoder is undefined" error". Because it isn't defined.
One way to fix it would be to add this to the global scope (just before your initialize function):
var geocoder = new google.maps.Geocoder();
Or you could do it the way it is done in the example you used, it is inside the initialize function there.
working example
My code:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script type="text/javascript" src="jquery.ui.map.full.min.js"></script>
<script>
function initialize() {
$('#map_canvas').gmap().bind('init', function() {
// This URL won't work on your localhost, so you need to change it
// see http://en.wikipedia.org/wiki/Same_origin_policy
$.getJSON( 'demo.json', function(data) {
$.each( data.markers, function(i, marker) {
$('#map_canvas').gmap('addMarker', {
'position': new google.maps.getLatLng(marker.town),
'bounds': true
}).click(function() {
$('#map_canvas').gmap('openInfoWindow', { 'content': marker.content }, this);
});
});
});
});
}
</script>
Why does the google.maps.getLatLng not work?
UPDATE:
$('#map_canvas').gmap('addMarker', { geocoder = new google.maps.Geocoder(); 'position': new google.maps.LatLng(geocoder.getLatLng(marker.town)), 'bounds': true })
How do I find the latutide and longitude based on a town name? I have just tried the above without result.
Why does the google.maps.getLatLng not work?
Where do you find that in the documentation?
The correct syntax for the google.maps.LatLng constructor is:
new google.maps.LatLng(<latitude>, <longitude>)
where <latitude> and <longitude> are numbers
To get the geographic coordinates of a postal address, you need to use a geocoder.
dear professionals.
I want to make info window for each markers on google maps.
My code:
google.maps.event.addListener(marker, 'click', function() {
new google.maps.InfoWindow({content: content}).open(map, marker);
});
show infowindow only for last marker.
Please, give me example or link to tutorial.
This is a modification of my answer to this question: Maps API Javascript v3 how to load markers with a mouse click
It loads an array of markers with info windows, and displays the last one added.
