Menu
I have a page that uses the Google Maps API to display a map. When I load the page directly, the map appears. However, when I try to load the page using AJAX, I get the error:
Uncaught ReferenceError: google is not defined
Why is this?
This is the page with the map:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
var mapOptions = { zoom:7, mapTypeId: google.maps.MapTypeId.ROADMAP, center: chicago }
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
directionsDisplay.setMap(map);
}
$(document).ready(function(e) { initialize() });
</script>
<div id="map_canvas" style="height: 354px; width:713px;"></div>
And this the page with the AJAX call:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
<script>
$(document).ready(function(e) {
$('button').click(function(){
$.ajax({
type: 'GET', url: 'map-display',
success: function(d) { $('#a').html(d); }
})
});
});
</script>
<button>Call</button>
<div id="a"></div>
</body>
</html>
Thanks for your help.

You can do that by accessing Application restrictions, then navigate to “HTTP referrers” then type in your domain's name. After making the necessary changes, click Save. Copy the API key because you will need it to get the map back on your website.
Go to the Google Maps Platform > Credentials page. On the Credentials page, click Create credentials > API key. The API key created dialog displays your newly created API key. Click Close.
The API can't be loaded after the document has finished loading by default, you'll need to load it asynchronous.
modify the page with the map:
<div id="map_canvas" style="height: 354px; width:713px;"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&callback=initialize"></script>
<script>
var directionsDisplay,
directionsService,
map;
function initialize() {
var directionsService = new google.maps.DirectionsService();
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
var mapOptions = { zoom:7, mapTypeId: google.maps.MapTypeId.ROADMAP, center: chicago }
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
directionsDisplay.setMap(map);
}
</script>

I know this answer is not directly related to this questions' issue but in some cases the "Uncaught ReferenceError: google is not defined" issue will occur if your js file is being called prior to the google maps api you're using...so DON'T DO this:
<script type ="text/javascript" src ="SomeJScriptfile.js"></script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
Uncaught ReferenceError: google is not defined error will be gone when removed the async defer from the map API script tag.

At a guess, you're initialising something before your initialize function:
var directionsService = new google.maps.DirectionsService();
Move that into the function, so it won't try and execute it before the page is loaded.
var directionsDisplay;
var directionsService;
var map;
function initialize() {
directionsService = new google.maps.DirectionsService();
directionsDisplay = new google.maps.DirectionsRenderer();
}
