How is it possible to use the Google Maps API with AngularJS?
I am using this code in my AngularJS app:
<style>
#googleMap {
width: 200px;
height: 200px;
}
</style>
<div id="googleMap"></div>
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js"></script>
<script language="javascript">
var map;
function initialize() {
var mapOptions = {
mapTypeId: google.maps.MapTypeId.ROADMAP,
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
map = new google.maps.Map(document.getElementById('googleMap'), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
This code is in the view and not in the controller.
I have other functions in the view and they work, but google map is still not working.
This is the error I get in the browser console:
Error: google is not defined

What am I doing wrong?
I searched the web but everyone seems to be using libraries like angular-google-map or ui-map. Why is no one using the direct API?
You can implement google maps in angularjs without using any plugins like this,
<!--use this div where ever you want to create a map-->
<div id="map"></div>
define the width and height for map div,
#map {
height:420px;
width:600px;
}
in controller you glue this id="map" with scope like this,
$scope.mapOptions = {
zoom: 4,
center: new google.maps.LatLng(41.923, 12.513),
mapTypeId: google.maps.MapTypeId.TERRAIN
}
$scope.map = new google.maps.Map(document.getElementById('map'), $scope.mapOptions);
if you want to create markers for the cities or countries you want,
var cities = "Atlanta, USA";
var geocoder= new google.maps.Geocoder();
$scope.markers = [];
var createMarker = function (info){
var marker = new google.maps.Marker({
map: $scope.map,
position: new google.maps.LatLng(info.lat(), info.lng())
});
}
geocoder.geocode( { 'address': cities }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
newAddress = results[0].geometry.location;
$scope.map.setCenter(newAddress);
createMarker(newAddress)
}
});
Last but not least make sure you added the google maps api script before doing all this stuff,
<script type="text/javascript" src="https://maps.google.com/maps/api/js?sensor=false"> </script>
Here is the working plunker with this code, inside a bootstrap model,

Hope this helps!
It was late to post but I have done this as solution. By this there is no need to add the google map script src in the head of the html or there is no chance of any error for google map src related errors. The script will be added automatically by the loadScript function. In angular it is needed to add new js src in partials rather than the head of main script. So I think this will be the best solution
I used this code chunk into my controller.
$scope.initialize = function() {
$scope.mapOptions = {
zoom: 8,
center: new google.maps.LatLng(22.649907498685803, 88.36255413913727)
};
$scope.map = new google.maps.Map(document.getElementById('googleMap'), $scope.mapOptions);
}
$scope.loadScript = function() {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://maps.google.com/maps/api/js?sensor=false&callback=initialize';
document.body.appendChild(script);
setTimeout(function() {
$scope.initialize();
}, 500);
}
setTimeout is there because some time is needed for google map src to be downloaded and be ready. & callback=initialize is needed because by this google map will be ready for a callback.The main problem was that the code google.maps.event.addDomListener(window, 'load', initialize) was not executing if I add the google map src in partial rather than the head of main index.html. But this setup works flawlessly.
And this chunk to the html
<div class="form-group col-lg-12" id="googleMap">
<center>Waiting for the map...</center>
</div>
Now place ng-init="loadScript()" anywhere in any outer div so that loadScript initializes before.

I want to display a Google map - however, the latter isn't filled (no Google's logo is shown, neither the cities, streets, etc.). There's no error in the console. Here is an illustration of the problem:
Sources
The following code is an extract. Tags like <body>, etc. are not shown.
<div style="width: 500px; height: 500px;">
<div style="width: 500px; height: 500px;" id="page-gaz-de-ville-map"></div>
</div>
<script type="text/javascript">
$(document).ready(function() {
var map;
$.getScript('https://maps.googleapis.com/maps/api/js?key=XYZ', initMap);
function initMap() {
var clusterStyles = [];
var mapstyles = [];
map = new google.maps.Map(document.getElementById('page-gaz-de-ville-map'), {
styles : mapstyles
});
}
});
</script>
Question
It is a fake API key.
Why is the map empty and how can I fix the problem?
I would recommend loading the js file as:
<script async defer src=".....key=XYZ&callback=initMap"></script>
This should ensure the deferred loading which I guess you were trying to achieve through the getScript call.
And define the initMap function at a script element in the head tag. Did the trick for me.
Please take the below code,
<!--- First of all need to add below script --->
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=Your Key&v=3&libraries=places,visualization"></script>
<!--- Below code is used to invoke the google map --->
<script type="text/javascript">
$(document).ready(function() {
myLatlng = new google.maps.LatLng(64485, 2674827.909);
var myOptions = {
zoom: 18,
zoomControl: true,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
myMarker = new google.maps.Marker({
position: myLatlng
});
myMarker.setMap(map);
});
</script>
<!--- Html code --->
<div style="width: 600px; height: 400px;" id="map_canvas"></div>
Let me know if you have any questions.
This is actually You Want. 1st You Must Add HTML, BODY Tags, then Must Import JQuery Plugin ($(document) is JQuery)
$(document).ready(function () {
var map;
$.getScript('https://maps.googleapis.com/maps/api/js?key=XYZ', initMap);
function initMap() {
var myOptions = {
zoom: 12,
center: new google.maps.LatLng(9.981496491854426, 76.30557754516597),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('page-gaz-de-ville-map'), myOptions);
}
});
You need to generate an api key.
and replace the XYZ, in javascript call, by your key.
I'm building a websites, that occupies the Google Maps JS API, but for some reason, the map stays white, but there's no error in the Google Chrome Console.
HTML code:
<div id="map-container-5" class="z-depth-1" style="height: 200px"></div>
<script src="https://maps.google.com/maps/api/js?key"></script>
JS code:
function myMap() {
var mapProp= {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5,
};
var map=new google.maps.Map(document.getElementById("map-container- 5"),mapProp);
}
I'm not really getting the point, why this is not working, as there's no error.
My kind of template was: https://www.w3schools.com/graphics/tryit.asp?filename=trymap_intro
If you want to simply show a map with your coordinates using the googleapi then do as follows. This will show the map with your lat and lng.
CSS:
#map {
height: 400px; /* The height is 400 pixels */
width: 100%; /* The width is the width of the web page */
}
The HTML
<div id="map"></div> /* Place on your page
And this BEFORE the /body tag with YOUR key
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=YOURKEY&callback=initMap">
</script>
And the JS script which again is places about the /body
<script>
function initMap() {
// The location of Uluru
var uluru = {lat: 51.5087420, lng: -0.120850};
// The map, centered at Uluru
var map = new google.maps.Map(
document.getElementById('map'), {zoom: 10, center: uluru});
// The marker, positioned at Uluru
var marker = new google.maps.Marker({position: uluru, map: map});
}
</script>
Your code is correct. You just need to call the myMap() function once it is defined.
Try running the snippet below. (Same as your code with an additional line for calling myMap() function.)
function myMap() {
var mapProp = {
center: new google.maps.LatLng(51.508742, -0.120850),
zoom: 5,
};
var map = new google.maps.Map(document.getElementById("map-container-5"), mapProp);
}
myMap();
<div id="map-container-5" class="z-depth-1" style="height: 200px"></div>
<script src="https://maps.google.com/maps/api/js?key=AIzaSyC7q_f_aMi9o-hoSl3PYSVHRlN99AU3nBg"></script>
The API key you used is W3Schools one! API keys are used for Google to ask for money when your map gets lots of views.
You can get your own API key at https://cloud.google.com/maps-platform/ but you also need to register your credit card (or a fake one).
Note that you don't need an API key if your project is local (not served via HTTP).
(Also you didn't call myMap, so be sure to add myMap() to the end of your code.)
first you have to get your own key for google maps api. then you need to correct the tag like this.Also you have to call your "myMap" function.
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=myMap" async defer></script>
you then want to replace "YOUR_API_KEY" in the code with your key.
and "myMap" with your function name which in this case is the same (myMap)
In your style try using a valid height and width, and be sure the div is visible at startup
<div id="map-container-5" class="z-depth-1" style="height: 200px; width:200px;"></div>
And try remove the last comma in mapProp
var mapProp= {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5
};
Is not cleat how invoke the function myMap().. so try also using the code directly in
<script>
var mapProp= {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5
};
var map=new google.maps.Map(document.getElementById("map-container- 5"), mapProp);
</script>
and check in your javascript console .. for error
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)
proof of concept fiddle
code snippet:
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,
});
}
google.maps.event.addDomListener(window, 'load', initMap);

I am work in ZK and now I am need use the Google API maps. I have used this API in other framework sometimes.
I don't show the maps.
Firstly I thought the problem may be the css, but it isn't.
I added a initialize (maps) function to a event onLoad of windows but I had still the same problem. I debug the code in the browser with the js console and I seen that the window event load isn't available so I called the function initialize from the event load from the div (which contents the maps), again the js console showed the same message.
I use a directive
<div id="map_canvas" style="width: 320px; height: 480px;" xmlns:w="http://www.zkoss.org/2005/zk/client" w:onClick="initialize()"></div>
But the div wasn't shown.
Finally I used a pure html element, using the html tag of ZK:
<html><![CDATA[
<div id="map_canvas" onload="initialize()" style="width: 320px; height: 480px;"/>
]]></html>
but the result in the js console is again
<div class="noscript"><p>Sorry, JavaScript must be enabled.<br/>Change your browser options, then try again.</p></div>
I'd like know way the function which shows the maps don't do it. I think the problem is the js but I am not sure, do anybody tell me if the problem is the js called please?
Thanks.
Edit:
I have used this way to do it (Thank you very much to Sean Connolly: How get the zk element id from js)
<zk>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=API_KEY&sensor=false">
</script>
<script type="text/javascript">
var map;
function initialize() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(zk.Widget.$(jq('$map_canvas2')).$n(), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<div id="map_canvas2" style="width: 1320px; height: 1480px;" />
I think you want something like this:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
}
function codeAddress() {
var address = document.getElementById("address").value;
geocoder.geocode({'address': address},
function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
alert(results[0].geometry.location.latlng[0]);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
initialize();
</script>
<div id="map_canvas" style="width: 320px; height: 480px;" onClick="initialize()"></div>
I have searched a lot of solutions for this problem but none worked out for me. I would like to integrate Google Maps into a Wordpress page, without using a plugin and without embedding.
In the head of header.php I attached this:
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=*********&sensor=true"> </script>
Then also in header.php I have put this:
<body onload="initialize()">
But now I don't know where to put the script:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(50.371, -4.136),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
function loadScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "https://maps.googleapis.com/maps/api/js?key=AIzaSyDo2uLLlKn3xuYolvd0VNzBujoZ952YywE&sensor=true&callback=initialize";
document.body.appendChild(script);
}
window.onload = loadScript;
If anybody has a solution I would really appreciate it, thanks a lot!
You can put the code into a js file and load it after the api script include.
A little bit cleaner code would be:
(function () {
function initMap() {
var mapOptions = {
center: new google.maps.LatLng(50.371, -4.136),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initMap);
}());
With this self calling anonymous function you don't introduce globals and encapsulates you code.
