<!DOCTYPE html>
<html>
<head>
<title>BART</title>
<style>
body
{
height: 100%;
}
#map
{
height: 80%;
width: 60%;
}
</style>
<script src = "https://maps.googleapis.com/maps/api/js?key=mykey</script>
<script>
var map ;
//function to initialize map
var initialize = function()
{
var mapOptions = {
center :{lat: 37.775362, lng: -122.417564},
zoom : 12,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
}
window.onload = initialize;
</script>

<div id ="map">

You should add CSS as
#map {
height: 400px;
width: 400px;
}
<!DOCTYPE html>
<html>
<head>
<title>BART</title>
<style>
body {
height: 100%;
}
#map {
height: 400px;
width: 400px;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?"></script>
<script>
var map;
//function to initialize map
var initialize = function() {
var mapOptions = {
center: {
lat: 37.775362,
lng: -122.417564
},
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
}
window.onload = initialize;
</script>
</head>
<body>
<div id="map">
</div>
</body>
</html>
Please use the code provided in google map documentation.

and js file
function initMap() {
alert("Inside initMap");
var uluru = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
if i am removing (from html file)
<style>
#map {
height: 400px;
width: 100%;
}
</style>
then map is not showing but a error in console is coming (in image)
any body can please tell me how style or css can effect this
(with style tags)
after tried a lot , I had apply previous answer but not got proper solution . Actually I want that when user enter address of location then my code must show that address on map in web . But it is not happening .
convert.js :-
geocoder=new google.maps.Geocoder();
function getCoordinates(address,callback)
{
var coordinates;
geocoder.geocode({address:address},function(results,status){
alert('Called');
coordsx=results[0].geometry.location;
//coords1=results[0].geometry.location;
coordinates=[coordsx.lat(),coordsx.lng()];
callback(coordinates);
//alert(coordinates)
})
}

The line map=new google.maps.Map(document.getElementById('map-canvas'),mapOptions); needs to be inside the anonymous function function(coords){.. where mapOptions is defined. This should work:
<!DOCTYPE html>
<html>
<head>
<title></title>
<style>
#map-canvas {
width: 700px;
height: 600px;
position: absolute;

}
</style>
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script src="convert.js"></script>
<script>
google.maps.visualRefresh=true;
function initialize() {
var mapOptions;
getCoordinates('J-24 MIG colony indore',function(coords){
mapOptions = {
center: new google.maps.LatLng(coords[0],coords[1]),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map=new google.maps.Map(document.getElementById('map-canvas'),mapOptions);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas" height="100%" width="100%%"></div>
</body>
</html>
The problem is that you had not put map object so it happens try to put these in your code ,
map=new google.maps.Map(document.getElementById('map-canvas'),mapOptions);
It will surely work
New tiles are not being loaded on drag and release. Instead just the blank background is shown.
Zoom in or out will load a new map.
I'm loading the current release: http://maps.google.com/maps/api/js
<style type="text/css"> .single_map_canvas img { max-width: none; } </style>
<div class="single_map_canvas" id="single_map" style="height: 225px; width: 450px;"></div>
<script type="text/javascript">
function initialize() {
var singleLatlng = new google.maps.LatLng(37.5364,-122.2455);
var mapOptions = {
zoom: 12,
center: singleLatlng,
draggable: true
}
var map = new google.maps.Map(document.getElementById('single_map'), mapOptions);
var marker = new google.maps.Marker({
position: singleLatlng,
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
UPDATE: This has to be inside the <head> tag.
<style type="text/css"> .single_map_canvas img { max-width: none; } </style>
<!DOCTYPE html>
<html>
<head>
<!-- <title>Simple Map</title>

hope this helps
most probably ur network is slow, i guess
I would like to break this code into one JS, CSS and HTML file each. How could I do that?
<!DOCTYPE html>
<html>
<head>
<title>Simple Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script>
var map;
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
You can move the Javascript (contents between scripts tags) to a separate file, for example
<script src="scripts/myscripts.js"></script>
Similarly you can move the CSS (contents between style tags and embed it like this:
<link rel="stylesheet" href="my.css" />
So your Javascript file would look like this:
var map;
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
and your CSS file like this:
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
// html
<!DOCTYPE html>
<head>
<title>
</title>
<link rel="stylesheet" type="text/css" href="style2.css">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
// load google map
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js? key=&sensor=true">
</script>
<script type="text/javascript">
var myLatlng = new google.maps.LatLng(33.319914, 44.304771);
var marker = new google.maps.Marker({map: map, position:myLatlng, title:"Hello World!"});
var map = null;
function initialize()
{
var mapOptions =
{
center: new google.maps.LatLng(33.319914, 44.304771),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true,
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
// marker.setMap(map);
}
// second map with marker
function initialize2()
{
var mapOptions =
{
center: new google.maps.LatLng(33.319914, 44.304771),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true,
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);

if (searchvalue == "1")
{

}

// if there is a better way to load markers with the seachbox or button im all ears been trying all day
// css

}
#map-canvas
{
height: 500px;
width: 500px;
margin: 50px 50px 50px 50px;
}
#searchwrapper
{
width:310px;
height:40px;
background-image:url('images/searchbox6.png');
background-repeat:no-repeat;
padding:0px;
margin:0px;
position:relative;
}
#searchwrapper form
{
display: inline;
}
.searchbox
{
border:0px;
background-color:transparent;
position:absolute;
top:4px;
left:9px;
width:256px;
height:28px;
color: #fff;
}
.searchbox_submit
{
border:0px; /*important*/
background-color:transparent; /*important*/
position:absolute; /*important*/
top:4px;
left:265px;
width:32px;
height:28px;
}
stop the form from summiting, like this:
$('#upload').submit(function(e){
e.preventDefault();
...
});
Hope this helps :/
