Google Maps doesn't load the 2nd time - AngularJS

问题

I'm using the GoogleMap API ('angular-google-maps' js package) and I have a very weird behavior.

The first time I load it, i get the full map loaded, like here:

Then i close the dialog and reopen it, i see this:

Keep in mind, that the map is displayed as a dialog on top of another dialog.

Any ideas?

If you are using Angular Google Map module you must add the refresh attribute to the googlemap element.

As it written in the Module documentation:

refresh = "expression" - Expression which, if it evaluates to true, will trigger a map refresh. Useful when the map is initially hidden.

You have to redraw the map. You can do this using the following code:

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

This will make the map refresh, fixing your issue.

just add:

$scope.render = true;

and add ng-if="render" to your your map control, like this:

<ui-gmap-google-map ng-if="$parent.render" center="map.center" zoom="map.zoom">
        <marker coords="map.center"></marker>
    </ui-gmap-google-map>

Issue is answered here https://github.com/allenhwkim/angularjs-google-maps/issues/88

you need to center it manually to avoid this problem like the following,

In your js controller

$scope.$on('mapInitialized', function (event, map)
{
    window.setTimeout(function() {
      window.google.maps.event.trigger(map, 'resize');
      map.setCenter(new google.maps.LatLng(38,-98));
    }, 100)
});

And in your HTML

<ng-map ng-if="subView=='map'" center="38,-98" zoom="5"></ng-map>
