Recenter A Google Map After Container Changed Width

I have a google map set with the Javascript API V3. It's displayed in a div with a dynamic width, as a content pane slides up when we click on a marker. Everything works fine, but

Solution 1:

Calling resize by it self will not acheive what you need.

What you need to do is first (before a resize occurs) get the current center of the map

var currCenter = map.getCenter();

Then you need to do something like the following, after your div is resized.

google.maps.event.trigger(map, 'resize');
map.setCenter(currCenter);

Should do the trick

UPDATE 2018-05-22

With a new renderer release in version 3.32 of Maps JavaScript API the resize event is no longer a part of Map class.

The documentation states

When the map is resized, the map center is fixed

• The full-screen control now preserves center.

• There is no longer any need to trigger the resize event manually.

source: https://developers.google.com/maps/documentation/javascript/new-renderer

google.maps.event.trigger(map, "resize"); doesn't have any effect starting from version 3.32

Solution 2:

First set a variable for the current center, then use a event listener to detect a resize, and thusly set center.

//Get current centervar getCen = map.getCenter();

//Use event listener for resize on window
google.maps.event.addDomListener(window, 'resize', function() {
   //Set Center
   map.setCenter(getCen);
});

omarello does work but I can't upvote it. You probably forgot to refer to the var that defines your center coordinates. All "resize" does is pull the divs current width and height, it does not change anything about the map--yet!

var center = new google.maps.LatLng(39.5, -98.3);

$(document).ready(function() { 
    $("#fullsize").click(function(e) { 
        e.preventDefault();
        $("#map_canvas").css({ 
            width: '1000px'});
        google.maps.event.trigger(map, "resize"); 
        map.setCenter(center);
        }); 
    });

Solution 4:

Hy there try this ;)

On map initialization

var currentMapCenter = null; 
google.maps.event.addListener(map, 'resize', function () {
    currentMapCenter = map.getCenter();
});

google.maps.event.addListener(map, 'bounds_changed', function () {
    if (currentMapCenter) {
    // react here
        map.setCenter(currentMapCenter);
    }
    currentMapCenter = null;
});

After this just call when tou want the map resize.

google.maps.event.trigger(map, 'resize');
