I have used a real API key in place of {API_KEY}
How can I achieve my objective?

I pasted your code into a file named test.html, inserted a valid api key and tested the following browsers in MAC OS X 10.9:
Safari
Chrome
Firefox
It works in all these browser without any error. Please check the following:
Validation period of your api key
invisible characters

Why can't Google Maps API access custom CSS file from JS in HTML file?

HTML with JS
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="~/css/custom.css" />
</head>
<body>
<h3>My Google Maps Demo</h3>
<div id="map">
<script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCQKR41AqiPXn-2WfLS-ksdsad&callback=initMap"></script>
<script>
function initMap() {
var uluru = { lat: 51.957244, lng: 4.570751 };
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
</script>
</div>
</body>
</html>
CSS
#map {
width: 100%;
height: 400px;
background-color: grey;
}
The specific problem is that when I put CSS in the HTML with #map the map shows and works but from the separate file it just doesn't show. Why?
EDIT: Making a MVC application via Visual Studio
EDIT 2: Something with the file location was wrong. I created a new project and put the CSS in a file that was already made. Now it's working.
First things first - put your script tags into head and try again. I suspect that there's some funky stuff with google maps replacing contents of #map and removing scripts in the process.
It should be <link rel="stylesheet" type="text/css" href="./css/custom.css" /> Use . insteads of ~

Quartz Composer JavaScript

I'm really stuck so any help would be appreciated. TIA!
I have a Quartz Composition in which I want to display a Streetview (from Google Maps) and be able to control the navigation (as in be able to advance forward, etc.). This would mean I need a JavaScript for it and I've got no idea on how to link the JavaScript Patch in QC with the Google Maps API.
So how could I add two strings, representing Lat and Long and display the Streetview?
Here is a sample HTML from Google doing that:
<!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 type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var bryantPark = new google.maps.LatLng(37.869260, -122.254811);
var panoramaOptions = {
position:bryantPark,
pov: {
heading: 90,
pitch:0,
zoom:0
}
};
var myPano = new google.maps.StreetViewPanorama(document.getElementById("pano"), panoramaOptions);
myPano.setVisible(true);
}
</script>
</head>
<body onload="initialize()">
<div id="pano" style="width: 1280px; height: 1024px"></div>
</body>
</html>
How could I do this in Quartz Composer JavaScript Patch or any other patch?
Thanks a lot!
P.S.: It already works partially by loading the page with CoGe Webkit Plugin for QC. But I have no idea on how to control the JavaScript inside the HTML via QC. Any other way to send variables from QC to a HTML page or anything similar?
Really easy actually, hope it will help others as well.
HTML:
function initialize(x, y) {
var pos = new google.maps.LatLng(x, y);
// whatever else you need it to do
}
QC:
initialize(x, y)
Thanks to the creator of the CoGe WebKit plugin, Tamas Nagy for the answer!
