This is the first time I've used a google api and I followed the instructions exactly but the map won't load just the grey box that I started with, please help.
<div class="map">
</div>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk&callback=initMap">
</script>
function apimap() {
var uluru = {lat: -73.993439, lng: 40.750545};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
It seems there's an issue regarding your implementation. You are using apimap() as your init function while in your load request's callback, you are using initMap(). You should replace initMap() with apimap() or vice-versa. With this, your map will work.
I've replicated your issue, the location is in Antartica. You can check the demo below.
var map;
function apimap() {
var uluru = {lat: -73.993439, lng: 40.750545};
map = new google.maps.Map(document.getElementById('map'), {
center: uluru,
zoom: 4
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
height: 100%;
margin: 0;
padding: 0;
}
<div id="map"></div>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCzjs-bUR6iIl8yGLr60p6-zbdFtRpuXTQ&callback=apimap"
async defer></script>
And also, please refrain from posting your Google Maps API key unless it is restricted to prevent abuse and to avoid your API key being used by unauthorized applications. To learn more about API restrictions, you can check Restricting an API key.
Hope it could help and good luck on your coding!

i have multiple google map instances on my website,now there are two different google map on a same page, what happens is the first one works and other doesn't now i know the logical issue let me show you my code first
<script>
function initMap() {
var myLatLng = {lat: 43.6222102, lng:-79.6694881};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
center: myLatLng
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
});
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=my_key&callback=initMap"
async defer></script>
now as i defined a callback method it always initializes the method named initMap whereas what i want to do is there can be multiple google maps lets suppose initMap2 how can i load them without callback method?
To load the map without a callback, load the API synchronously/inline (without the async defer), then call your initMap function on the load event.
(Note: FYI: Google changed all their examples to using asynchronous loading to improve the load times)
(Note2: Google has added a "sample" to their documentation describing synchronous loading)

function initMap() {
var myLatLng = {

Would anybody possibly know what could be the issue here? The console does not show any errors.
Thank you.

Remove this CSS rule from your page and it will work...
If you are trying to hide certain features from the map, don't do it with CSS. Do it with the map options.
I'm using Squarespace to build my website and want to insert a custom map from google maps javascript api. I've already gotten google api key.
I've followed steps as below :
What I'm trying to archive is just to show a google map on my web.
Step 1: Insert a embed block for html
<div id="map_canvas"></div>
Step 2: insert javascript in page header
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=my-key&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
Step 3 : in custom css section
#map_canvas
{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px
}
But the codes I put on Squarespace didn't work. How should I do?
Here the link to my webpage on SquareSpace
Your Site Title
Thanks!!
LoL, u put the script at a very wrong place i think.
1st. put your script, all of it after </body>
2nd. you need a cover for your maps <div> like a wrapper or so to put it in center. and using a cover/wrapper div you can manipulate the size and the shape.
3rd. i don't know id="maps_canvas". because from google i got this <div id='gmap_canvas' style='height:100%;width:100%; position:static'>, it was gmap_canvas. and put style in it to make them fit with your cover/wrapper div.
easier way: http://embedgooglemaps.com/en/
perhaps it'll help. :)
This is what I changed in my code as below :
Step 1: Insert a code block for html <-- it was not embed block, but code block. I mistyped before.
<div id="mapWrapper">
<div id='gmap_canvas' style='height:100%;width:100%; position:static'>
</div>
</div>
Step 2: insert javascript in page header.
I change only ID name from 'map_canvas' to 'gmap_canvas'
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=my-key&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('gmap_canvas'), myOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
Step 3 : in custom css section.
Changed ID name from 'map_canvas' to 'mapWrapper', then set another size.
#mapWrapper
{
width: 750px;
height: 500px;
margin: 0px;
padding: 0px
}
I tried to put most of everything people advised me, but still the map doesn't come up on my site.
Is there something wrong yet?
I did the same thing with my site.
What I did differently is not put my #map-canvas within a wrapper. While previewing your site, are you able to find your gmap_canvas with the inspect view? It may be that the content is there, just not displaying properly.
My code:
The following is in the page header code injection box. Note that a large bit of this code (and I don't remember which parts since I don't know JS) is just to keep the pin centered on different screen sizes.
<style type="text/css">
html, body, #map-canvas {
height: 400px;
width 960px;
margin: 0;
padding: 0;}
#banner-area-wrapper {
display: none;
}
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=my_key&callback=initMap">
</script>
<script type="text/javascript">
function detectBrowser() {
var useragent = navigator.userAgent;
var mapdiv = document.getElementById("map-canvas");
if (useragent.indexOf('iPhone') != -1 || useragent.indexOf('Android') != -1 ) {
mapdiv.style.width = '100%';
mapdiv.style.height = '100%';
} else {
mapdiv.style.width = '600px';
mapdiv.style.height = '800px';
}
}
function initialize() {
var myLatLng = {lat: 39.910073, lng: -82.965509};
var mapOptions = {
center: myLatLng,
zoom: 14,
panControl: false,
mapTypeControl: false,
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.DEFAULT,
position: google.maps.ControlPosition.LEFT_CENTER},
streetViewControl: false
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Opportunity Center'
});
google.maps.event.addDomListener(window, "resize", function() {
var center = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
});
}
On the page, I have a code block, with the following in it:
<div id="map-canvas" style="width:90%;margin:auto;"></div>
Note that I did not put my #map-canvas inside a wrapper, nor include anything in the custom CSS.
I made a quick dummy site, and replicated your failure to show the map, but I don't know quite enough about Squarespace to say exactly why. I'd start with copying my code and see if that works for you - seems like the big difference is your wrapper around the canvas.
Google yesterday released v3.22 of their maps api which moves a bunch of the standard controls.
According to the Google Blog at http://googlegeodevelopers.blogspot.co.uk/2015/09/new-controls-style-for-google-maps.html#gpluscomments you can temporarily revert to the old controls, but I can;t get this to work at all.
The blog post says to simply add google.maps.controlsStyle = 'azteca' before you initialize the map, but I'm still getting the old controls displayed and they clash with some of my custom controls.
I've tried adding the line right at the start of my initialize() routine (which sets up all of the map options and creates the map object; and also right before the map = new google.maps.Map() statement.
Has anyone got any pointers as to what I'm doing wrong?
They have a typo in the post (and in the documentation)
Issue in the issue tracker
google.maps.controlsStyle = 'azteca';
should be:
google.maps.controlStyle = 'azteca';
code snippet:
var map;
function initMap() {
google.maps.controlStyle = 'azteca'
map = new google.maps.Map(document.getElementById('map'), {
center: {
lat: -34.397,
lng: 150.644
},
zoom: 8
});
}
google.maps.event.addDomListener(window, 'load', initMap);

google.maps.controlStyle = 'azteca';
I'm trying to set a contact page in which I display google's map to indicate the place of a meet. I'm currently using using these codes:
js
(function(){
document.getElementById('map_canvas').style.display="block";
var myOptions = {
zoom: 14,
center: new google.maps.LatLng(0.0, 0.0)
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
})();
html
<script type="application/javascript" src="/js/google-map.js">
<div id="map_canvas" style="width:80%; height: 400px; margin:auto;"></div>
The problem is that I couldn't be able to mark the indicated place like in google map to precise to the user the indicated place. Any brilliant idea, please?
First you need to define the Latitude and Longitude of the mark
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
Then you need to add a marker:
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
