Is it possible to re initialize a gmap3 map to its default settings (lat, long, zoom etc)?
I tried destroy on the map and then re run the initialise but it is not working.
See my jsfiddle here - http://jsfiddle.net/vlowe/z9dDE/1/
Wrap the map element in a container div, and then when you want to reset the map, just remove the whole map div and recreate it. This should solve the problem.
According to the gmap3 documentation, you still need to call destroy on the map before removing the dom element.
HTML code
<div>
<div id="map"></div>
</div>
restore
JavaScript
var dlat = 53.9783997; // default map latitude
var dlng = -1.5666347; // default map longitude
var dzoom = 6; // default map zoom
var dmaptype = "roadmap"; // default map type
// create gmap
$('#map').gmap3({
action: 'init',
options: {
center: [dlat, dlng],
zoom: dzoom,
mapTypeId: dmaptype,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
},
navigationControl: true,
scrollwheel: true,
streetViewControl: true
}
});
function restore() {
$('#map').gmap3({
action: 'destroy'
});
var container = $('#map').parent();
$('#map').remove();
container.append('<div id="map"></div>');
// create new gmap
$('#map').gmap3({
action: 'init',
options: {
center: [dlat, dlng],
zoom: dzoom,
mapTypeId: dmaptype,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
},
navigationControl: true,
scrollwheel: true,
streetViewControl: true
}
});
}
Here's an alternative method:
rather than destroying the map and recreating it entirely, you could save the initial state and the restore it to that state like this: http://jsfiddle.net/UvAL3/1/
(these functions existed as part of the API in V2)

I'm using the google map angular component and it's working pretty good!
But now I want to remove some of the landmarks from the map to reduce its congestion, to be able to show my markers a little more clearly.
I've found these resources below but can't figure out how to apply it to the <google-map> node package I'm using.
Site to create json for hiding landmarks and other features on map
shows how to hide map features from google map dev site
SO link that describes same issue
I see in this google documentation it shows applying styles to 'googlemap' with 'setMapStyle()' but this isn't a method in the angular package
Here below is my component (not all code) where I'm using google maps but it shows how I'm using the all code for the map
import {
MapInfoWindow,
MapMarker,
GoogleMap
} from '#angular/google-maps';
export class YogabandEventsComponent implements OnInit {
colContentRef: ElementRef;
#ViewChild(GoogleMap, {
static: false
}) googleMap: GoogleMap;
#ViewChild(MapInfoWindow, {
static: false
}) infoWindow: MapInfoWindow;
zoom = 12;
center: google.maps.LatLngLiteral;
options: google.maps.MapOptions = {
mapTypeId: 'roadmap',
mapTypeControl: false,
scrollwheel: true,
maxZoom: 18,
minZoom: 10,
streetViewControl: false,
fullscreenControl: false
};
markers: Marker[];
infoContent = '';
constructor(...) { ...
}
openInfo(marker: MapMarker, content) {
this.infoContent = content;
this.infoWindow.open(marker);
}
showMarkers() {
this.markers = [];
for (const ybEvent of this.yogabandEvents) {
const marker = new Marker();
marker.info = ybEvent.name;
marker.title = ybEvent.name;
marker.position = {
lat: ybEvent.latitude,
lng: ybEvent.longitude
};
marker.label = {
color: '#17a2b8',
text: ybEvent.yogaType,
fontWeight: 'bold',
fontSize: '16px'
};
marker.options = {
icon: {
// scaledSize: new google.maps.Size(40, 40),
url: 'assets/images/marker.svg',
labelOrigin: new google.maps.Point(18, 50)
}
};
this.markers.push(marker);
}
}
}
<div class="col flex-fill h-100 px-0 right-col">
<google-map [options]="options" [zoom]="zoom" [center]="center" class="h-100" height="100%" width="100%">
<map-marker #markerElem *ngFor="let marker of markers" [position]="marker.position" [label]="marker.label" [title]="marker.title" [options]="marker.options" (mapClick)="openInfo(markerElem, marker.info)">
</map-marker>
<map-info-window>{{ infoContent }}</map-info-window>
</google-map>
</div>
Try with the styles property of the MapOptions interface.
Like this:
options: google.maps.MapOptions = {
mapTypeId: 'roadmap',
mapTypeControl: false,
scrollwheel: true,
maxZoom: 18,
minZoom: 10,
streetViewControl: false,
fullscreenControl: false,
styles: [...]
};
It could gets a bit annoying styling it detailed. You can generate a set of styles from this Styling Wizard (it also have a Landmarks slide to remove them gradually, then just export the styles array).
I have an overlay placed on a google map:
function CustomerMarker(map) {
this.Map = map;
this.setMap(map);
}
GoogleMap = new google.maps.Map(document.getElementById("map"), {
zoom: 16,
canZoom: false,
center: { lat: lat, lng: lng },
mapTypeControl: false,
streetViewControl: false,
scaleControl: false,
clickableIcons: false
});
CustomMarker.prototype = new google.maps.OverlayView();
CustomMarker.prototype.onAdd = function () {
//Some code
};
CustomMarker.prototype.draw = function () {
//Some code
};
CustomMarker = new CustomMarker(GoogleMap);
Which works fine, and the overlay shows up, however is issue arises when I try to remove that
CustomMarker.setMap(null)
I get an error and the marker remains
Error: this.remove is not a function

The documentation for OverlayView states:
You must implement three methods: onAdd(), draw(), and onRemove().
I don't see an implementation for onRemove.
I've included the Modernizr Touch Events detection to my project (only left the rest out to keep it light as possible).
I use it to set different Google Maps JS options as following:
<script>
function initMap() {
var myLatLng = {lat: 52.022322, lng: 4.209055};
if( Modernizr.touchevents ) {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
disableDefaultUI: false,
center: myLatLng,
scrollwheel: true,
draggable: false,
});
} else {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
disableDefaultUI: false,
center: myLatLng,
scrollwheel: false,
draggable: true,
});
}
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Duijnisveld Kasconstructies',
});
}
</script>
I've included this script in my page-contact.php file which displays the contact page on my Wordpress project.
Whenever I view the page I see no map and note the following error in my console:
(index):235 Uncaught ReferenceError: Modernizr is not defined
What am I missing here?
Thanks guys!
You are calling Modernizr before theme-min.js which is where you are defining it.
You should move your code below this line.
<script type="text/javascript" src="http://duijnisveld.wpengine.com/wp-content/themes/duijnisveld-kascontructies/scripts/min/theme-min.js?ver=4.5.3"></script>
I am trying to load Google Maps API in a webpage with the <script> tags at the bottom of the body with the #map element referenced above.
Get the error alert: "This page was unable to display a Google Maps element. The provided Google API key is invalid or this site is not authorized to use it. Error Code: InvalidKeyOrUnauthorizedURLMapError"
My API KEY is definitely correct; I have checked it multiple times.
I have chosen to accept request from the following referrers
*.mywebsite.com/*
*.mywebsite.com*
www.mywebsite.com/*
www.mywebsite.com/test // this is the url I am trying to load the map on.
I have tried without the API Key Reference and without the Init callback and the map loads intermittently. Sometimes it will load (around 20% of the time), other times it doesn't and I get the following console log - ReferenceError: google is not defined;
<script async defer src="https://maps.googleapis.com/maps/api/js?key=MY_API_KEY&callback=initMap"></script>
<script src="/js/map.js"></script>
My map.js file containing the map config
var map;
var mapLatLng = {lat: 13.778182, lng: -0.23676};
var mapStyle = [maps style options] // https://snazzymaps.com/style/38/shades-of-grey
var mapMarker = '/img/marker.png';
function initMap() {
var styledMap = new google.maps.StyledMapType(mapStyle,
{name: "Styled Map"});
var mapOptions = {
center: mapLatLng,
zoom: 10,
scrollwheel: false,
navigationControl: false,
mapTypeControl: false,
scaleControl: false,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'map_style']
}
};
var map = new google.maps.Map(document.getElementById('map'),
mapOptions);
var marker = new google.maps.Marker({
position: mapLatLng,
map: map,
title: 'Hello World!',
icon: mapMarker
});
//Associate the styled map with the MapTypeId and set it to display.
map.mapTypes.set('map_style', styledMap);
map.setMapTypeId('map_style');
}
google.maps.event.addDomListener(window, 'load', initMap);
You call the GMap script as async defer, so you are not sure that the script will be downloaded and executed before map.js. And your map.js script call the GMap API.
Could you test first without the async defer attribute. If it's ok, just move all your initialization code in the initMap function, it should work :
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
var marker = new google.maps.Marker({
position: mapLatLng,
map: map,
title: 'Hello World!',
icon: mapMarker
});
//Associate the styled map with the MapTypeId and set it to display.
map.mapTypes.set('map_style', styledMap);
map.setMapTypeId('map_style');
var styledMap = new google.maps.StyledMapType(mapStyle, {name: "Styled Map"});
var mapOptions = {
center: mapLatLng,
zoom: 10,
scrollwheel: false,
navigationControl: false,
mapTypeControl: false,
scaleControl: false,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'map_style']
}
};
}
I'm try to set map center using gmapjs. When I resize the window I get:
Uncaught TypeError: undefined is not a function
Here the map and the listener for the resize event:
$(function () {
var holder = $('#map-property'),
lat = 46.534820,
lng = 13.024809;
var map = new GMaps({
div: '#'+holder.attr('id'),
lat: lat,
lng: lng,
zoom: 14,
scrollwheel: false,
panControl : false,
streetViewControl: false,
mapTypeControl: false,
draggable: true,
disableDoubleClickZoom: true,
zoomControlOptions:{
style:google.maps.ZoomControlStyle.SMALL
}
})
.addMarker({
lat: 46.534820,
lng: 13.024809,
title: 'Da Matteo',
icon: "/img/gmaps-marker.png"
});
$(window).on('resize', function() {
map.setCenter(lat, lng); // here is the error!
});
});
AFAIK the setCenter function is:
this.setCenter = function(lat, lng, callback) {
this.map.panTo(new google.maps.LatLng(lat, lng));
if (callback) {
callback();
}
};
The problem is, map = new Gmaps().addMarker() returns a marker object, not a map. Therefore it has no setCenter method.
You can do something like:
var map = new Gmaps({...})
map.addMarker({...})
Then write the event.
