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.
This question is related to
ajax
google-maps-api-3
What worked for me after following all your workarounds was to call the API:
<script async defer src="https://maps.googleapis.com/maps/api/js?key=you_API_KEY&callback=initMap&libraries=places"
type="text/javascript"></script>
before my : <div id="map"></div>
I am using .ASP NET (MVC)
Might not be relevant for everyone but this little detail was causing mine not to work:
Change div from this:
<div class="map">
To this:
<div id="map">
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, directionsService;
var map;
function initialize() {
directionsService = new google.maps.DirectionsService();
directionsDisplay = new google.maps.DirectionsRenderer();
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.
For me
Adding this line
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
Before this line.
<script id="microloader" type="text/javascript" src=".sencha/app/microloader/development.js"></script>
worked
