The fitBounds() method in Google Maps API V3 is extremely helpful for adjusting

I am trying to display a map on my website using this code:

function initialize() {
    var myOptions = {
      center: new google.maps.LatLng(45.4555729, 9.169236),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP,

panControl: true,
mapTypeControl: false,
panControlOptions: {
            position: google.maps.ControlPosition.RIGHT_CENTER
        },
zoomControl: true,
zoomControlOptions: {
    style: google.maps.ZoomControlStyle.LARGE,
    position: google.maps.ControlPosition.RIGHT_CENTER
},
scaleControl: false,
streetViewControl: false,
streetViewControlOptions: {
    position: google.maps.ControlPosition.RIGHT_CENTER
            }
        };
    var map = new google.maps.Map(document.getElementById("mapCanvas"),
        myOptions);



var Item_1 = new google.maps.LatLng(45.5983128 ,8.9172776);

var myPlace = new google.maps.LatLng(45.4555729, 9.169236);

var marker = new google.maps.Marker({
    position: Item_1, 
    map: map});

var marker = new google.maps.Marker({
    position: myPlace, 
    map: map});

var bounds = new google.maps.LatLngBounds(myPlace, Item_1);
map.fitBounds(bounds);

    }

Although the two points are 25 km apart, the zoom level is not high enough for my liking. I want to render a higher zoom level.

To achieve this, I am using the fitBounds() method.

    var bounds = new google.maps.LatLngBounds(myPlace, Item_1);
    map.fitBounds(bounds);

Any assistance or advice on how to improve this would be greatly appreciated. Thank you!

Answer №1

The reason for this issue is that the LatLngBounds() function requires SW and NE points, not just any two random points.

To address this, you can utilize the .extend() method on a newly created bounds object.

var bounds = new google.maps.LatLngBounds();
bounds.extend(myLocation);
bounds.extend(Point_A);
map.fitBounds(bounds);

Check out the demonstration here: http://jsfiddle.net/jane/37bds/

Answer №2

LatLngBounds must always have points in the (south-west, north-east) order. It seems like your points are not arranged correctly.

If you are unsure whether the points are in the right order, a good solution is to create an empty bounds and then extend it with the desired points:

var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

By following this method, the API will automatically adjust the bounds for you.

Answer №3

Even though I am facing a similar issue as you described, my approach involves gradually constructing my LatLngBounds as suggested above. The challenge lies in the asynchronous nature of things, and executing map.fitBounds() at an incorrect time could result in a scenario like the one mentioned in the question. To address this, I have discovered that placing the call within an idle handler works best, like so:

google.maps.event.addListenerOnce(map, 'idle', function() {
    map.fitBounds(markerBounds);
});

Answer №4

 const myMap = new google.maps.Map(document.getElementById("map"),{
                mapType: google.maps.MapTypeId.ROADMAP

            });
const boundaries = new google.maps.LatLngBounds();

for (let x = 0; x < locations.length; x++){
        marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[x][1], locations[x][2]),
            map: myMap
        });
boundaries.extend(marker.position);
}
myMap.fitBounds(boundaries);
