For the first time I'm trying to incorporate the Google Maps API into a website and it's not working at all. I can't tell if there's something wrong with the code and I'd like to rule that out before trying to create another API Key
I've moved the tag around and tried different styling approaches, but it just doesn't show anything.
<!DOCTYPE html>
<html>
<head>
<script>
function initMap() {
var location = { lat: -30.0327268, lng: -51.2095745 };
var map = new google.maps.Map(document.getElementById("map"), {
zoom: 4,
center: location
});
}
</script>
<script async defer
src="https://maps.googleapis/maps/api/js?key=AIzaSyBDXh6FfycwxdCaHUbrCWkswSarA77kowY&callback=initMap">
</script>
<title>
</title>
<style>
* {
margin: 0;
padding: 0;
}
#map {
height: 500px;
width: 100%;
}
</style>
</head>
<body>
<div id="map"></div>
</body>
</html>
The URL in the script that you are using is incorrect.
You are using: https://maps.googleapis/maps/api/js?key=AIzaSyBDXh6FfycwxdCaHUbrCWkswSarA77kowY&callback=initMap
The correct URL: https://maps.googleapis.com/maps/api/js?key=AIzaSyBDXh6FfycwxdCaHUbrCWkswSarA77kowY&callback=initMap
Hope this helps!
The below line was not added correctly,
It should be in this form
Below is the updated code in which map is working fine..

Google API map not displaying when I load my code in a google chrome browser. I created my authentication key with in a new project on the Google Cloud Platform.

As I've already stated, the google map api will not display a map of my actual location.
You have two issues with the posted code.
Your map div doesn't have a size, you need to define the size of html and body so the #map 100% height has something to reference:
<style>
#map{
height:100%;
}
</style>
should be:
<style>
html, body, #map {
height: 100%;
margin: 0;
padding: 0;
}
</style>
you have an unneeded src on your script tag:
<script src="app.js">
should be:
<script>
proof of concept fiddle
html,
body {
height: 100%;
margin: 0;
padding: 0;
}
#map {
height: 90%;
}
<div id="output">Complete JavaScript Course </div>
<div id="map"></div>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk"></script>
<script>
window.onload = init;
var m = document.getElementById('map');
function init() {
navigator.geolocation.getCurrentPosition(placeMap);
}
function placeMap(data) {
var options = {
center: {
lat: data.coords.latitude,
lng: data.coords.longitude
},
zoom: 5
}
var map = new google.maps.Map(m, options);
console.dir(data);
}
</script>
You need to access the API using the callback after google maps have already been loaded. This is done by passing in a parameter to google maps initialization by passing in callback as a query parameter. You also need to activate your api to have Javascript functionality

i'm tring to create an html file whith google API to display on google MAPS a KML File.
this is the HTML Code:

});
var ctaLayer = new google.maps.KmlLayer({

when i launch the html, the google maps start but my kml is not visualized.
Help!!
Thanks in advance Vincenzo
Your KML file must be accessible on the public Internet - that is, it must be accessible to any machine which is connected to the internet.Make sure your kml file is publicly accessible
/* This is the javascript function that makes the map load */
function initMap() {
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
center: {
lat: 44.540,
lng: -78.546
},
zoom: 8
});
}
/* This is the basic css */
#map {
width: 500px;
height: 400px;
}

your function is not calling use $(document).ready(function()()) for call your function

you need to add a DOM listener that will execute the initMap() function on window load.
try this
function initMap() {
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
center: new google.maps.LatLng(44.540, -78.546),
zoom: 8
});
}
google.maps.event.addDomListener(window, 'load', initMap);
#map {
width: 500px;
height: 400px;
}
<script src="https://maps.googleapis.com/maps/api/js" ></script>
<div id="map"></div>
This should be pretty basic but I cant really find the answer to it:
I try to implement a Google map, using the Google API for business and got a working client ID / key.
Using the standard examples from for the documentation (https://developers.google.com/maps/documentation/javascript/tutorial) its only possible to get a blank map.
This is the simple test code that show a blank map:
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
I need to get the correct map with all the info and places that its containing.
All the examples I find are for getting a blank map, or adding stuff to it.
Thanks,

Your supplied JavaScript works for me. Have you included the required div in your webpage?
<div id="map-canvas"/>
Plus the div may need to be styled, as the map may be there but with 0px height and 0px width (hence making it impossible to see), the following CSS will make your div fullscreen:
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map-canvas { height: 100% }
So, overall, you should have this:
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map-canvas { height: 100% }
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=API_KEY">
</script>
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"/>
</body>
</html>
I am working with Google Maps and I want to load the map in an external file, where I can use jQuery to set up the rest of the page.
I have made three changes to the Hello World example: I've included jQuery, I've initialised the map in an external file, and I've removed the onload event in the <body> tag. And I now have a blank screen where there used to be a map, and no console errors to give me a clue.
This is my HTML:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script src="./js/jquery.js"></script>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=true">
<script src="./js/maps.js"></script>
</head>
<body>
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
This is maps.js in full:
$(document).ready(function () {
console.log('document ready');
function initializeMap() {
console.log('initialize');
var myOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
initializeMap();
});
I don't see any of the console statements. I also don't see a map - just a blank screen.
I must be doing something stupid, but what is it?
You're missing an </script> after src="http://maps.googleapis.com/maps/api/js?sensor=true">
