I am developing an application and this chrome extension is part of that web application. Whenever user launches this extension it should display a map with predefined markers. Here is my sample code which I wrote test.html
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<link rel="stylesheet" type="text/css" href="style.css" />
<script src="http://maps.googleapis.com/maps/api/js"></script>
<script>
function initialize() {
var mapProp = {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="loading">
<div>
<img src="img/sunny.png" />
<p>Getting Data From Server</p>
</div>
</div>
<div id="wrapper">
<div id="weather"></div>
<div id="googleMap" style="width:500px;height:380px;"></div>
</div>
</body>
</html>
Main.js
chrome.app.runtime.onLaunched.addListener(function() {
chrome.app.window.create('weather.html', {
id: 'weather',
innerBounds: {
height: 450,
width: 300,
},
resizable: true
});
});
It opens a popup window but doesn't load map. While this html file is working perfectly when I open it directly in a browser.

I try to make a leaflet map and added Openstreetmap as a background map. But if I load the map, nothing appears. Checking the firefox network analysis all the required tiles are loaded succesfully, but they do not show.
My HTML code :
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="https://unpkg.com/leaflet#1.4.0/dist/leaflet.css" integrity="sha512-puBpdR0798OZvTTbP4A8Ix/l+A4dHDD0DGqYW6RQ+9jxkRFclaxxQb/SJAWZfWAkuyeQUytO7+7N4QKrDh+drA==" crossorigin=""/>

</head>
<body>
<div id="map">
</div>
<div id="logo">
<!--- a logo will appear here --->
</div>
<script src="map.js"></script>
</body>
My javascript code :
var map = L.map('map', {
center: [51.505, -0.09],
zoom: 13
});
var osm = new L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
});
osm.addTo(map);
The div "map" has a higher z-index than "logo", so that should not be the problem.
Where is map style ?
You should give a height and a width to your map in order to be rendered
<div id="map" style="width: 600px; height: 400px;">
Demo
My page has been loaded with google map but using Jquery i am hiding it. On click of button it should display my google map loaded in that page. but i am not able to see the full map,i.e. am seeing only a part of map.
Below is my code:-

You're loading the Google maps using window's onload event and for a hidden element. Then you're again showing it so the maps is bit stuck to get resized.
So when you show the div, trigger the resize event of Google maps like
$(document).ready(function() {
$("#maps12").hide();
$("button").click(function() {
$("#maps12").show();
google.maps.event.trigger(map, "resize");
});
});

Having a bit of trouble placing a map within data-role="content" while using Google Maps v3 and JQuery. No errors show in the console so I am having a hard time debugging. No map shows up on the screen.
Here are my two files:

mapload.js
function initialize()
var mapOptions = {
center: new google.maps.LatLng(49,-8),
zoom: 15,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"),mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
This gave me some insight but didn't complete answer my question.

There's only one available way of using Google maps with jQuery Mobile. Because jQuery Mobile is specific window load can't be used to initialize the map.
Specifically correct height is needed to initialize the map successfully and it can ONLY be done during the jQuery Mobile pageshow page event. If you want to find out more about jQuery Mobile page events and why is pageshow event important for plugin initialization take a look at my private blog ARTICLE. Or you can find it HERE.
Let me make this story short, here's a working example: http://jsfiddle.net/Gajotres/pkZHg/
And here's a javascript and CSS used:
Javascript
$(document).on('pageinit', '#index',function(e,data){
var map = new google.maps.Map(document.getElementById('map_canvas'), {
center: new google.maps.LatLng(42.618044,-87.823347),
zoom: 15,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
});
CSS
#content {
padding: 0;
position : absolute !important;
top : 40px !important;
right : 0;
bottom : 40px !important;
left : 0 !important;
}
load mapload.js at the end of the html
<div data-role="page" id="map">
<div data-role="header">
<h1>Header</h1>
</div>
<div data-role="content">
<div id="map-canvas"></div>
</div>
</div>
<script type="text/javascript" src="js/mapload.js"></script>
the DOM is not ready yet when you are calling the map functions
the other error might be CSS styling.. you could try this
a set width and height
`
#map-canvas {
width: 480px;
height: 640px;
}
`
I just check out the demos for jquery-ui-map here http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-mobile.html#basic_map
This is exactly what I am trying to implement, its very basic, I just did as they did in the example but it doesn't seems working, I tested it on Chrome Desktop browser.
Here is the source:

This shows only header and footers for now.
There is one important thing, when I give some height to the map div, it shows Static map image.
Just got it working now, Source code is fine. There was a problem because jQuery Mobile Map respond to Touch event.
In Chrome touch event are not enabled by default, so just turn on the Touch event in Chrome Console.
What I am trying to achieve from past 2 days is that - I could show a error msg on my jquery mobile page when there is no internet connection that 'Sorry, No internet connection.'
I have tried alot of stuff but none worked. Code below is now when last I tried by using try-catch block. But even this ain't helping. Following happens when i load the page in browser -
When Internet Connection Available - Map Loaded and works perfectly fine.
When No Internet Connection - I get blank page. without page header and footer. with some default grey background and that looks bad for my application. :(
Any kind of help is appreciable. I am still learning.
Code am using right now is given below -

script element triggers onerror event, when it can't load the script. You can add handler and track whether script loaded successfully:
<script src="http://maps.google.com/maps/api/js?sensor=false"
onerror="javascript:alert('No internet connection.')"></script>
UPDATE: You could try something like this:
