How can I remove the info-windows but keep the actual landmark visible? I just don't want the actual info-window to appear when the landmark is clicked because I have markers around landmarks and sometimes the landmarks are accidentally clicked instead.
Those are called clickableIcons.
To turn off the InfoWindows, set the MapOption clickableIcons: false.
From the documentation
:
clickableIcons | Type: boolean
When false, map icons are not clickable. A map icon represents a point of interest, also known as a POI. By default map icons are clickable.
code snippet:
function initialize() {
var map = new google.maps.Map(
document.getElementById("map_canvas"), {
center: new google.maps.LatLng(37.4419, -122.1419),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP,
clickableIcons: false
});
}
google.maps.event.addDomListener(window, "load", initialize);
html,
body,
#map_canvas {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px
}
<script src="https://maps.googleapis.com/maps/api/js"></script>
<div id="map_canvas"></div>
I am able to capture the google map image. But I want it to capture automatically. I am able to but it has image which is not fully rendered. So I want to know is there any proper way to know that required tiles are loaded and rendered fully.I tried tilesloaded, idle events but seems not working rightly.
is it a good way to use idle under tilesloaded...i may sound wrong as i'm very new to google map api.
function initialize() {
var mapOptions = {
zoom: 17,
center: new google.maps.LatLng(lat,lng),
mapTypeId: google.maps.MapTypeId.ROADMAP,
rotateControl:true
};
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
google.maps.event.addListener(map, 'tilesloaded', function(event) {
console.log("tilesloaded");
map.addListener('idle', function(event) {
console.log("idle");
});
});
}
google.maps.event.addDomListener(window, 'load', initialize);
you can easily add a listener on the tilesloaded event. Like this:
google.maps.event.addListener(map, 'tilesloaded', function() {
..... your code ...
});
Does anyone know how i would move the pan/zoom control position of google maps whilst inside streetview?
I can position the controls to the right side on normal map view, but when streetview is activated the pan control and the zoom buttons switch over to the left hand side?
How would i go about telling these to position to the right whilst streetview is active?
Thanks!
I've tested the following code and it worked for me
map.get('streetView').setOptions({
panControlOptions: map.get('panControlOptions'),
zoomControlOptions: map.get('zoomControlOptions')});
the streetView has it's own control-options which will not be inherited from the map.
You must explicitly set these control-options for the streetView:
<script>
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(42.345573,-71.098326),
zoom: 14,
panControlOptions:{
position:google.maps.ControlPosition.RIGHT_TOP
},
zoomControlOptions:{
position:google.maps.ControlPosition.RIGHT_TOP
}
};
var map = new google.maps.Map(
document.getElementById('map-canvas'), mapOptions);
//apply the map-settings for panControl and zoomControl to the streetView:
map.get('streetView')
.setOptions({panControlOptions: map.get('panControlOptions'),
zoomControlOptions: map.get('zoomControlOptions')});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<div id="map-canvas" style="width: 400px; height: 500px"></div>
I'm having a heck of a time trying to get a basic Google Map to show up. I've been on Stack Overflow for hours and haven't had any success so far. The closest I've gotten is the map loads 1/4 of a square, the top left quarter. But then if you try to drag, zoom, etc it just turns grey like the rest of the map. On a few occasions, with the same code, the map will load fully but only after a long time (not sure exactly how long, but > 5 minutes).
In my template I have
<div id="map" style="width: 500px; height: 400px;"></div>
And then in my backbone view
$.getScript('http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback')
window.gMapsCallback = function(){
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
}
Any ideas what might be happening? I am also open to any suggestions on a superior way to load a google map into a backbone view.
Ok, turns out there were a number of issues, including embedding a map in a Bootstrap tab, not including a callback, defining the div height and width, setting a small delay to load the map, and setting css attributes for the map. Oi. My final solution turned out to be:
In the template
<script src='http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback'></script>
<div id="map" style="width: 500px; height: 400px;"></div>
In the stylesheet
#map img {
max-width: none;
}
#map label {
width: auto; display:inline;
}
In the Backbone View
setTimeout(function(){
var myLatlng = new google.maps.LatLng(53.1, -2.44);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
// Create marker
var marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(53.1, -2.44),
title: 'The armpit of Cheshire'
});
// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
map: map,
radius: 10000, // metres
fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');
google.maps.event.trigger(map, "resize");
map.setZoom( map.getZoom() );
}, 100);
Painful. Notice that when I call the gmaps script I had to include the callback even though I never use it. Without it, it didn't work fully. No clue why.
As part of a much bigger project, we're trying to get a Map on a site using Google's Map API v3. I have followed the simplest steps that Google has laid out, I've tried copying code outright from other working maps. But no matter what I do, all we get is a gray box and no map.
Using Firebug, I can see the information trying to populate the map, but it is simply not displaying. I've tried jquery, jquery libraries specifically made for google maps, nothing is working. I have been up and down the internet and all through google's api help files. Plus, the problem is not local as I've uploaded the file to multiple servers and tested it on multiple browsers and computers. Nothing is working.
At this point it's got to be something stupid that I'm overlooking. Here's my code.

This works for me. You simply have to set zoom parameter:
UPDATE (by #user2652379): You need to set BOTH zoom and center options. Just zoom does not work.

Another case is when map container is hidden at the moment you initialize the map. E.g. you are doing it inside bootstrap show.bs.modal event, instead of shown.bs.modal
I had the same issue and came across a lot of topics on stackoverflow but none of them had the working solution for me. I eventually found out it was caused to a line of css I had added.
All the elements in the map inherited a
overflow:hidden;
By adding the following line to my CSS it was fixed
#map * {
overflow:visible;
}
I would like to add a quick comment to this since I had the same problem with the zoom parameter set.
I found out that the problem was my theme's css. In my base theme I had the following CSS:
img, embed, object, video {
max-width: 100%;
max-height: 100%;
width: auto;
height: auto;
}
This messed up the rendering of the map and after I removed it, my map renders just fine.
Also beware of having an invalid latitude or longitude value for the map center or your markers. For example, this fiddle shows the Grey Map Of Death because the map center is at latitude 131.044 which is invalid (not from +90:-90).
function initMap() {
var uluru = {lat: 131.044, lng: -25.363};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
In my case, I was working on a map with vue and a modal in the iview library; and during the first render it worked, but any other render displayed the grey screen of death. I fixed the issue by setting a timeout function to display the map after 50 ms to give the modal enough time to render and be visible.
//Time out is crucial for the map to load when opened with vue
setTimeout(() => {
this.showMap(id);
}, 50);
The above example was an earlier fix and a quick hack, i have realized all you need to do is wait for the next tick, on vue you can achieve this by
async mounted(){
await this.$nextTick()
this.showMap(id)
}
or if you are not comfortable with async await you can try the callback option
mounted(){
Vue.nextTick(function () {
this.showMap(id)
})
}
I had the same issue. i was using google maps in Jquery Accordion and when i expand the div the map only consisted a grayed area. I was able to solve this issue by triggering a click event on the specified accordion heading and setting the map container to visible.
Script:
<script type="text/javascript">
var map;
function initMap(lat, lng) {
var myCenter = new google.maps.LatLng(lat, lng);
var mapOptions = {
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: myCenter
};
map = new google.maps.Map(document.getElementById('map'), mapOptions);
}
function ViewMap() {
var latlng = document.getElementById('<%=txt.ClientID%>').value.split(','); // This is where my latlng are placed: 25.12312,55.3212333
$("#showmap").show();
// Sorry for mixing up Jquery and javascript.
initMap(latlng[0], latlng[1]);
}
</script>
ASPX File/Html Markup:
<h3 id="lMap" onclick="ViewMap();"><i class="fa fa-map-o" onclick="ViewMap();"></i>Location Map</h3>
<div style="height:auto" id="showmap">
<div id="map" style="width: 850px; height: 550px; overflow: visible"></div>
</div>
I realise this is an old thread, but this may help someone in the future.
Struggled with this for hours, but after discovering that the Google Map is rendered with a grey box overlay if the map is rendered while not being visible, I used a bit of jQuery to make my application only instantiate and render the map if the map is visible, like such:
if ($("#myHomeMapHolder").is(":visible")) {
if (homemap == null) {
homemap = new google.maps.Map(document.getElementById("myHomeMapHolder"), myOptions);
google.maps.event.addListener(homemap, 'click', function (event) {
placeHomeMarker(event.latLng);
});
} else {
homemap.setCenter(myLatlng);
}
if (homemarker == null) {
homemarker = new google.maps.Marker({
position: myLatlng,
map: homemap,
title: "Home"
});
} else {
homemarker.setPosition(myLatlng);
}
}
And voila, my map is only rendered if the map holder is visible, so it never renders with a grey box.
For anyone wondering, myHomeMapHolder is a div which the map sits inside.
In my case, someone had dropped this little prize in some responsive.css file:
img {
max-width: 100% !important;
}
Removed that and all is fine now.
I had this issue with a site I'm working on too. We're doing some things to all <img> tags for responsiveness. This fix is working for us for the map:
img {max-width: initial !important;}
For those who might be stuck regardless of the nice solutions provided here, try setting the height and width of your container directly in the html markup instead of a stylesheet ie.
<div id="map-container" style="width: 100%; height: 300px;"></div>
happy mapping!
This may not be the case for everyone, but maybe it can help someone.
I was creating markers in my map from data attributes placed on the map element like this: data-1-lat="2" data-1-lon="3" data-text="foo". I was putting them in an array based on the order they were placed in the data attributes.
The problem is that IE and Edge (for some mad reason) invert the order of the data attributes in the HTML tag, therefore I wasn't able to correctly extract them from the data attributes.
None of the existing answers helped me because my problem was that Apollo was adding extra properties ("__typename" fields) to my MapOptions object.
In other words, the JSON looked like this:
mapOptions {"__typename":"MapOptions","center":{"__typename":"GeoCoordinates","lat":33.953056,"lng":-83.9925},"zoom":10}
Once I realized that those extra properties were problematic, this is how I solved it (using TypeScript):
function getCleanedMapOptions(mapOptionsGql: google.maps.MapOptions): google.maps.MapOptions {
const mapOptions = { ...mapOptionsGql };
const lat: number = mapOptions.center.lat as number;
const lng: number = mapOptions.center.lng as number;
const mapOptionsCleaned = {
center: new google.maps.LatLng({ lat, lng }),
zoom: mapOptions.zoom,
};
return mapOptionsCleaned;
}
export function createMap(mapOptions: google.maps.MapOptions): google.maps.Map {
const mapOptionsCleaned = getCleanedMapOptions(mapOptions);
const map = new google.maps.Map(document.getElementById('map') as HTMLElement, mapOptionsCleaned);
return map;
}
In my case (version is 3.30 when submitting this), it was because the div id MUST be "map"
<div id="map"></div>
...
document.getElementById("map")
