Google MAPS JS API doesn't load - javascript

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

Google map displayed but empty

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.

Google maps in odoo backend

I would like to show a google map in my Odoo contact page. I already installed a function that gets the Lat and Long but then i would like to show them in a map.
So far i was able to show the google map with the following code.
But I have 2 problems
1. the map is only visible after resizing my page manually
I don't know how to get die values from the odoo fields above.
Hope anyone can help! Thx
<div id="googleMap" style="width:100%;height:400px;"></div>
<script>
function myMap() {
var lat= 51;
var long= 2;
var mapProp= {
center:new google.maps.LatLng(lat,long),
zoom:10,
};
var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
google.maps.event.trigger(map, 'resize');
}</script>
<script src="https://maps.googleapis.com/maps/api/js?key=MY-KEY&callback=myMap"></script>
Thx for the answer but if I use your code i get the following error:
Change the H & W to a fixed value doesn't work either.
<h3>My Google Maps </h3>

Google Maps local not working constantly

I am trying to implement Google maps with a specified location on an website. Trying it for the first time, got the code from google dev and it doesn't work how it should, let me explain:
It works sometimes( when I load the page sometimes, or click in and out of other links, but not constantly) and no error on the log. I haven't noticed a pattern so that's why I am posting here. Really appreciate you reading this and giving your input!
First the HTML:
<h2>My Google Maps Demo</h2>
<div id="map"></div>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDwCEHnAjByWbixBh7zEm0VT712Cmlc(not the real key)callback=initMap">
</script>
<script src="javascript/scripts.js"></script>
Second the JS:
function initMap() {
var uluru = {lat: 46.77889, lng: 23.58624};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 16,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}

How does the Google Maps API work with AngularJS?

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,
http://embed.plnkr.co/VT7cO0L2ckSWG6g63TVG/preview

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.

Multiple Maps on One Page - ColdFusion

Getting stuck on Google Maps
Using ColdFusion - I am populating a list of Arena's...
I want a drop down of the maps if they have one - and link to add map. Links to populate the map and mark it work fine.
When I have multiple entries - I don't get multiple maps - only get map showing of last result.
I've tried some other coding I have used in past - but still no luck with multiple maps - so starting with this easier looking javascript.
Any help is appreciated. Deleting old code - going to what is currently working - just not showing markers
<img src="../images/gps1.png" height=25 border=0 alt="Show Map" onclick="javascript:showElement('g#aid#')">
Also - when I use style="display:none;" with the Google Map Div:
<div id="g#aid#" style="width: 600px; height: 300px;" style="display:none;"></div>
the drop down map is buggered and not centered. Without it - it closes and opens just fine - but is always defaulting to open.
As suggested - Here is Javascript output...
Here is output below for 2 results... Only last one shows map..
Below is some progress - starting at Google API - This is where I'm at...
There is a body onload to make this work...
All maps are showing properly... even added another... Just not getting markers...
I have tried Google Marker code... No luck yet... So just going to code that is displaying maps properly...
Just need to figure map marker out...
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<cfoutput query=arena">
<script>
var map;
function initialize() {
var mapOptions = {
zoom: 13,
center: new google.maps.LatLng(#arena.agpslat#,#arena.agpslong#),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('g#arena.aid#'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<div id="g#arena.aid#" style="width: 600px; height: 300px;"></div>
</cfoutput>
Adding this: Does not get me a marker...
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: '#arena.arename#'
});
The problem is you're calling the JS file and defining an identically-named function within your query loop. You need to move this stuff out of your query loop so you only call the file and create the function once.
So instead of having your initialise function recreated each time within the loop, move that out of the loop. And instead have the call to that function from within the loop, passing the different lat/lng values, div ID's and names into it each time.
Get rid of any existing calls to your initialize functions from the body tag and just use the google event listeners for when the window loads, passing different parameters each time to initialize.
Something like the following:
<script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script>
var arenas = []; // array of arenas, to be populated later within the query loop
function initialize() {
var intArena, myLatlng, mapOptions, map, marker;
// loop over all the arenas, creating maps and markers for each
for (intArena = 0; intArena < arenas.length; intArena++) {
myLatlng = new google.maps.LatLng(arenas[intArena].lat, arenas[intArena].lng);
mapOptions = {
zoom: 11,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById(arenas[intArena].id), mapOptions);
marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: arenas[intArena].name
});
}
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<cfoutput query="arena">
<cfif arena.agpslat is not "" and arena.agpslong is not "">
<script>
// add struct of arena data to the array for use later on in the initialize function
arenas.push({
lat: #arena.agpslat#,
lng: #arena.agpslong#,
id: 'g#arena.aid#',
name: '#JsStringFormat(arena.arenaname)#'
});
</script>
<div id="g#arena.aid#" style="width: 600px; height: 300px;"></div>
</cfif>
<div align=center>g#arena.aid#<br><b>[ <font color=cc3300>Change/Add Using Map Function</font> ]</b><br></div>
</cfoutput>
Also please note I've prefixed the references to your query columns with the query name. It's almost always a good idea to correctly scope all your variables.
Got... Thx for suggestions all...
Needs a
<body onload="initialize()">
ColdFusion Coding - used the variable to rename the function and mapoption - so they are always different.
<cfoutput query=arena>
<cfif arena.agpslat is not "" and arena.agpslong is not "">
<script type="text/javascript">
function initialize() {
var #arena.aid#Latlng = new google.maps.LatLng(#arena.agpslat#,#arena.agpslong#);
var #arena.aid#Options = {
zoom: 15,
center: #arena.aid#Latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("g#arena.aid#"), #arena.aid#Options);
var marker = new google.maps.Marker({
position: #arena.aid#Latlng,
map: map,
title: '#arena.arenaname#'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<div id="g#arena.aid#" style="width: 600px; height: 300px;"></div>
<div align=center>g#arena.aid#<br><b>[ <font color=cc3300>Change/Add Using Map Function</font> ]</b><br></div>
</cfif>
</cfoutput>
