Can I parse Javascript inside HTML - javascript

I have being trying to parse a HTML file using the following code below, I have a html file passed into the core.Element.parse, which is then rendered to the view:
this.newElement = core.Element.parse(html);
this.view.getContent().append(this.newElement);
html file looks like:
<div>
<html>
<head>
<style>
#map-canvas {
width: 250px;
height: 250px;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script>
function initialize() {
var mapCanvas = document.getElementById('map-canvas');
var mapOptions = {
center: new google.maps.LatLng(53.4333, -7.9500),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(mapCanvas, mapOptions)
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
</div>
Can someone tell me why the html, and css gets parsed but the javascript doesnt? When I inspect element the html is there and css but there is no sign of the javascript and nothing appears.
Thanks in advance for any help!

Why won't google maps show on my website, I have been using the developers website?

/* This is the javascript function that makes the map load */
function initMap() {
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
center: {
lat: 44.540,
lng: -78.546
},
zoom: 8
});
}
/* This is the basic css */
#map {
width: 500px;
height: 400px;
}
<!-- Javascript called into the html page -->
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id="map"></div>
<script src="https://maps.googleapis.com/maps/api/js" async defer></script>
</body>
</html>
your function is not calling use $(document).ready(function()()) for call your function
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.2.min.js" type="text/javascript"></script>
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script>
$(document).ready(function() {
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
center: {lat: 44.540, lng: -78.546},
zoom: 8
});
});
</script>
<style>
#map {
width: 500px;
height: 400px;
}
</style>
</head>
<body>
<div id="map"></div>
</body>
</html>
you need to add a DOM listener that will execute the initMap() function on window load.
try this
function initMap() {
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
center: new google.maps.LatLng(44.540, -78.546),
zoom: 8
});
}
google.maps.event.addDomListener(window, 'load', initMap);
#map {
width: 500px;
height: 400px;
}
<script src="https://maps.googleapis.com/maps/api/js" ></script>
<div id="map"></div>

Load Google Maps in HTML page when button is clicked

I have an HTML page with a list of buttons representing locations. When any button is clicked, I want a Google Map to appear with that location. Should the map open on a new HTML page? (because the map should take up the full page), or is it possible to display the map on the same page?
EDIT - OK, I want to open it in another HTML file. I have an external JS file which has the following Map code:
function initialize(lat, lng) {
var mapOptions = {
center: {lat: parseFloat(lat), lng: parseFloat(lng)},
zoom: 8,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize(-34.397, 150.644));
My external HTML file is given below:
<html>
<head>
<style type="text/css">
html, body, #map-canvas { height: 100%; margin: 0; padding: 0;}
</style>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?v=3&sensor=false"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="script.js" ></script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
But its not working. The external JS file cannot locate "map-canvas", it seems. Can anyone tell me how to fix this? (script.js is the external JS file)
I worked around your question try this :
<!DOCTYPE html>
<html>
<head>
<style>
#map-canvas {
width: 500px;
height: 400px;
}
</style>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

<div>
<a href="#" class="btn cta map-trigger" data-lat="41.8911684" data-lng="12.707724100000019" targe> Show Map3 </a>
</div>
<script>
var render_map = function( lat, lng, title ) {
var mapCanvas = document.getElementById('map-canvas');
// options
var args = {
zoom : 16,
center : new google.maps.LatLng(lat, lng),
mapTypeId : google.maps.MapTypeId.ROADMAP
};
// create map
var map = new google.maps.Map( mapCanvas, args);
// create marker
var marker = new google.maps.Marker({
position: args.center,
map: map,
title: title
});
toggleMap();
}
var toggleMap = function(){
if ($('body').hasClass('-show-map')) {
mapHide();
} else {
mapShow();
};
}
$('.map-trigger').on('click', function(event) {
event.preventDefault();
var lat = $(this).data('lat');
var lng = $(this).data('lng');
render_map(lat, lng);
});
</script>
<div id="map-canvas"></div>

Problems implementing Google Maps API (for Business)

This should be pretty basic but I cant really find the answer to it:
I try to implement a Google map, using the Google API for business and got a working client ID / key.
Using the standard examples from for the documentation (https://developers.google.com/maps/documentation/javascript/tutorial) its only possible to get a blank map.
This is the simple test code that show a blank map:
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
I need to get the correct map with all the info and places that its containing.
All the examples I find are for getting a blank map, or adding stuff to it.
Thanks,
/b
Your supplied JavaScript works for me. Have you included the required div in your webpage?
<div id="map-canvas"/>
Plus the div may need to be styled, as the map may be there but with 0px height and 0px width (hence making it impossible to see), the following CSS will make your div fullscreen:
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map-canvas { height: 100% }
So, overall, you should have this:
<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="https://maps.googleapis.com/maps/api/js?key=API_KEY">
</script>
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"/>
</body>
</html>

Custom Google Map won't show in div element

I'm trying to customize google map but I have a small problem.
Here is the css code:
#map-canvas {
width: 100%;
height: 500px;
}
and the js code:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
And this is how I initialize the map in html. This example actually works.
<div id="map-canvas"></div>
But when I trying to put my map into some div e.g:
<div>
<div id="map-canvas"></div>
</div>
It doesn't work. How to fix that ?
/// EDIT
Please put this into example.html and try to run. Nothing happens for me.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {

}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div>
<div id="map-canvas"></div>
</div>
</body>
</html>
Your parent div should have height and width defined.
<body>
<div style="height:100%; width:100%;">
<div id="map-canvas"></div>
</div>
</body>
Try This.

Google API not loading on my page

I'm trying to set up the google map api on my website so for part of a delivery service I'm offering. I copied the code directly from the sample on developers.google.com but for some reason my map wont load on my page!Ive gone through the code multiple times and cant get it to load...HELP!
<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 }
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBPiGhEEN1WjNHOtVoOMufbwsj_thBse2w&sensor=true">
</script>
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.mapTypeId.ROADMAP,
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
The html:
<body onload="initialize()">
<div class="map-canvas" style= "height: 100%">
</div>
</body>
I get a javascript error: Uncaught TypeError: Cannot read property 'ROADMAP' of undefined
This:
mapTypeId: google.maps.mapTypeId.ROADMAP,
Should be:
mapTypeId: google.maps.MapTypeId.ROADMAP,
The major problem is: Uncaught TypeError: Cannot read property 'offsetWidth' of null because your page doesn't have a div with id="map-canvas":
<div class="map-canvas" style= "height: 100%">
Should be:
<div id="map-canvas" style= "height: 100%;">
You are also calling initialize twice, change:
<body onload="initialize()">
To:
<body>

I see three issues
you use getElementById, but you give your div a class of map-canvas
it's *M*apTypeId (capital M)
you need to give your map-canvas div a fixed height
Also, since you are using addDomListener, it's unnecessary to also have an onload event on the body tag too. I would just use addDomListener.
