Enhance the visibility of the google.maps marker by zooming in

Question

Enhance the visibility of the google.maps marker by zooming in

I am having trouble properly zooming to a specific marker.

When trying to change the view to a designated marker, I am unable to achieve it successfully.

I have attempted:

map.setCenter(location);
map.setZoom(20);

as well as

map.fitBounds(new google.maps.latLngBounds(location,location));

In the first scenario, I find myself zoomed in without the center actually shifting. In the second case, the map displays an overview of a large area instead of zooming in.

One potential solution might involve using a delay between setting the center and adjusting the zoom level, but I consider that workaround less than ideal. I would much prefer a more elegant solution.

How do others approach this challenge?

Additionally, if there is a way to show the infowindow without altering its content, that would be a nice feature to have. However, my primary concern remains zooming in accurately on the marker.

Thank you for your assistance.

After some investigation, the resolution was

map.setZoom(17);
map.panTo(markerLocation.position);

For those in need of some example code, I thought I'd share an answer here.

I recently faced the challenge of zooming in and centering on a marker as soon as it was added to the map.

Hopefully, this code snippet proves useful for someone.

function findLocation(zip) {

    var geolocator = new google.maps.Geocoder();

    geolocator.geocode( { 'address': zip + ', UK'}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {

            var pin = new google.maps.Marker({
                map: map,
                position: results[0].geometry.location
            });

            map.setZoom(10);
            map.panTo(pin.position);
        }
        else {
            alert('Geocode was not successful due to: ' + status);
        }
    });
}

Are you creating a new instance of a map object? If so, you can simplify by creating an object that contains the location and zoom values, then pass that object to the map initialization process. You can follow this example from the Gmaps basics tutorial http://code.google.com/apis/maps/documentation/javascript/basics.html:

function initialize() {
    var myLatlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
        zoom: 8,
        center: myLatlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
