I encountered the following problem in completing my work:
Uncaught ReferenceError: google is not defined
Below is the code I ran:
<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>

<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>
What’s causing it, and how can it be resolved in the “uncaught referenceerror: google is not defined“ in the programs?
The cause:
This error occurs because by default, the API cannot be loaded after the document has completely loaded.
Solution:
It must be loaded asynchronously.
Let’s change the map page as needed to solve your problem:
Although this answer doesn’t directly relate to the question’s issue, in some cases the “Uncaught ReferenceError Google is Not Defined” error will occur if the google maps API you’re using is calling your js file before it…so DO NOT do this.
