I´m trying to put a google maps image into my HTML page. I cannot touch the <head> section as the page is dynamically loaded using PHP code (this logic is not explained here).
So, I´ve build the following HTML test code, that doesn´t work - the maps does not appear on screen.
<!DOCTYPE html>
<html lang="en-us">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta charset="UTF-8" />
<title>TEST PAGE</title>
</head>
<body>
<h1>Maps test page.</h1>
<script type="text/javascript">
function initialize() {
alert("Initialize");
var mapCanvas = document.getElementById("mapCanvas");
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644),
}
var map = new google.maps.Map(mapCanvas, mapOptions);
google.maps.event.addDomListener(window, "load", initialize);
}
window.onload = function() {
alert("Onload");
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js";
document.body.appendChild(script);
}
</script>
<div id="mapCanvas" style="width: 650px; height: 350px;"></div>";
<script type="text/javascript"> initialize() </script>
</body>
</html>
The alerts are coming up, but no map is shown...
Help is appreciated to make is work.
Asynchronously load the Google Maps Javascript API, use the callback parameter to run your initialize function.
working example
<html lang="en-us">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta charset="UTF-8" />
<title>TEST PAGE</title>
</head>
<body>
<h1>Maps test page.</h1>
<script type="text/javascript">
function initialize() {
alert("Initialize");
var mapCanvas = document.getElementById("mapCanvas");
var mapOptions = {

}
var map = new google.maps.Map(mapCanvas, mapOptions);
google.maps.event.addDomListener(window, "load", initialize);
}
window.onload = function() {
alert("Onload");
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js?callback=initialize";
document.body.appendChild(script);
}
</script>
<div id="mapCanvas" style="width: 650px; height: 350px;"></div>";
</body>
</html>
The problem is that initialize() is getting executed before the Google Maps Javascript has been added to the page. You aren't importing the Google Maps JS until the DOM has finished loading, in your window.onload callback. Try this instead:
<div id="mapCanvas" style="width: 650px; height: 350px;"></div>
<script src="http://maps.googleapis.com/maps/api/js"></script>
<script>
function initialize() {
alert("Initialize");
var mapCanvas = document.getElementById("mapCanvas");
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
var map = new google.maps.Map(mapCanvas, mapOptions);
}
window.onload = function() {
initialize();
};
</script>

I am currently have trouble loading my libraries=places into my google maps api. The api will let me either use the key OR libraries=places but not both. The error shows:
"Exception parsing document: template="index", line 10 - column 134"
line 10 is
script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key={MY_KEY}&libraries=places"
column 134 is the "=" between libraries and places.
Any suggestions would be welcome.
Can you try blow is updated;
<script type="text/javascript" th:src="#{https://maps.googleapis.com/maps/api/js(key='MY_KEY',libraries=places)}"></script>
I was able to get it to work with the following code:
<script type="text/javascript" th:src="#{https://maps.googleapis.com/maps/api/js(libraries=places, key=MY_KEY)}"></script>
I'm trying to follow this Google Maps example, but instead of hardcoding my API KEY, I'm trying to fetch it from an API I created.
So, I created this HTML file. The KEY is properly fetched, but when I'm trying to set the script's src attribute on runtime (so I can add my own key to the URI), it's not getting added at all.
This is my HTML

var marker = new google.maps.Marker({

</script>

$.get( "maps_api_key", function( data ) {

console.log("API_KEY: " + API_KEY)
var uri = "https://maps.googleapis.com/maps/api/js?key=" + API_KEY + "&callback=initMap"
console.log("URI is: " + uri)
$("#maps_fetcher").attr("src", uri)

src="https://maps.googleapis.com/maps/api/js?key=API_KEY&callback=initMap">
console.log("Map fetcher")
</script>
</body>
</html>
The line at console.log("Map fetcher") is never being printed either.
For what it's worth, I'm serving the HTML through Node and Express.
Any ideas on what could be happening here?
Thanks in advance

Add your api key in the script url
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" type="text/javascript"></script>
Ref https://developers.google.com/maps/documentation/javascript/get-api-key
I've tried all possible solutions but the map just isn't showing. My webview just shows blank.

I've narrowed down to this line: map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
When this line is executed, it fails.
Any help is appreciated.
Thanks.

I can't see myLatLng definition other than in centerAt() function. You need to pass Google Maps LatLng object to the center attribute of myOptions:
var myLatlng = new google.maps.LatLng(latitude, longitude);
var myOptions = {
zoom: 20,
center: myLatLng
}
...
And there is also a strange thing which I can't understand:
var map; " +
^ ^
my bad, submitted the wrong code. Anyway, the major issue here is the connection. That took me a long time to realize it since i was just focusing on the codes.
Thanks.
Why does my marker not appear?
I also tried without the line "marker.show", but the marker just seems not to appear.

This should do the trick:
var marker = new google.maps.Marker();
marker.setPosition(new google.maps.LatLng(47.3732589, 8.2382168));
marker.setMap(map);
You were close, but you forgot the new keyword when adding your position. It should look like this:
var marker = new google.maps.Marker({ position: new google.maps.LatLng(47.3732589, 8.2382168), title: 'x', map:map});
