I am trying to use the ArcGIS 2.1 JS API to create a custom interface that looks similar to Google Maps.
What is confusing me (particularly with Dojo's layout scheme) is how Google Maps has a map pane that extends the whole width of the page and has a left search results panel that seems to be floating above the map pane.
How does this work in terms of Dojo layouts? I have frustratingly worked with BorderContainers and looked at the documentation for a FloatingPane with no avail.
Any direction is appreciated.
Not sure what problem you're running into - either troubleshooting or design, but, here is a rigid construct example that might work:

You can substitute components for expando panes, and other gizmos, but this should technically work and look like:

Or you could just use the ArcGIS Extension for Google Maps :)

I was searching for free maps as an alternative to google maps to use in my website. As I searched I found leaflet. Referring the tutorial I tried creating a simple map in my localhost. But its loading blank. I am using leaflet for the first time. Is there anything I am missing out in my code? Can anyone help me..? Thanks in advance.
Here is my code:
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js"></script>
<style>
#map{ height: 100% }
</style>
</head>
<body>
<div id="map"></div>
<script>
var map = L.map('map',{
center: [43.64701, -79.39425],
zoom: 15
});
</script>
</body>
</html>
You need to add a tile layer to your map and try using one of the latest leaflet versions, such as 1.3.3. Moreover set a height like this:
#map{ height: 500px }
Try this
var map = L.map('map').setView([43.64701, -79.39425], 15);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
}).addTo(map);
L.marker([51.5, -0.09]).addTo(map)
.bindPopup('A pretty CSS3 popup.<br> Easily customizable.')
.openPopup();
#map {
height: 500px
}

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 ~
When I try to run this code in a browser, the google maps window appear, but the satelite or map image doesn`t show properly. I can hardly see the map or satelite image.

I am using JQuery mobile with the Google Map API.
The map is not displayed properly unless I refresh the page and I don't understand why.
here is my map.html file:
<div data-role="page" id="map-page">
<div data-role="content" id="canvas-map" style="background-color:red"></div>
<script src="js/map.js"></script>
<script type="text/javascript">
var $canvasMap = $('#canvas-map');
$('#canvas-map').on('pagebeforeshow', initMap());
</script>
</div>
and my map.js file:
function initMap() {
"use strict";
google.maps.visualRefresh = true;
var marker, map,
myLocation = {lat:50, lon:-80},
mapOptions = {
zoom: 5,
center: new google.maps.LatLng(myLocation.lat, myLocation.lon),
mapTypeId: google.maps.MapTypeId.PLAN,
disableDefaultUI: true
};
$('#canvas-map').css("height", "200px").css("padding", "0px");
map = new google.maps.Map(document.getElementById('canvas-map'), mapOptions);
/** MyPosition **/
marker = new google.maps.Marker({
map: map,
draggable: false,
animation: google.maps.Animation.DROP,
position: new google.maps.LatLng(myLocation.lat, myLocation.lon),
});
}
If I navigate from another page to the above page, I get the following result:
And then when I refresh, I get the expected result:
It is obviously not a problem with the canvas, since it is displayed (in red). Plus,if I navigate trhough the map, I can see the marker displayed at the right position.
These screenshots were made using Google Chrome, I tried with Firefox and the canvas is here completely red, no map at all.
PS: this is a simple version of my original code, but the behavior is the same.
EDIT:
See Gajotres' answer for details, but basically, within the link to access map.html page, adding target="_blank" solved the issue. Note that target="_self" seems to work as well, strange since it is supposed to be the default value. Details on target here.
There's a trick how google maps v3 framework can be easily implemented with jQuery Mobile.
Lets talk about the problems here. your content div has a height and width problem, mainly because only time page dimensions can be calculated correctly is during the pageshow event. But even then content div will not cover full page.
Your problem can be solved with a little bit of CSS :
#content {
padding: 0 !important;
position : absolute !important;
top : 40px !important;
right : 0 !important;
left : 0 !important;
height: 200px !important;
}
Basically you are forcing your content to cover available space.

If you take a look at this ARTICLE you will find much more information regarding this topic plus examples.
Try to add following code...
$('#canvas-map').on('pageshow', function(){
google.maps.event.trigger(canvas-map, "resize");
});
this will fire resize event and reload the map on your page.
Just for completeness: The action of drawing the map should be performed after the page loads, that is when the page has actual values for width and height and you can initialize it as follows:
var map; //declared as global so you can access the map object and add markers dynamically
$("#canvas-map").on( "pageshow", function() {
var mapProp = {
center:new google.maps.LatLng(53.6721226, -10.547924),
zoom:13,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
map=new google.maps.Map(document.getElementById("map-canvas"),mapProp);
});
No refresh needed
I am using Google Maps JavaScript API to load map inside my mobile website. When I navigate from the previous page map won't load but if I refresh the page map load as expected. If I use the JavaScript inside the body even the page is not loading. I can't figure out the problem. Is it something with the previous page code ?
Here is my code in Head tag.

I refer question This and This but it's not working with my code.
Problems
First of all, why are you using jQuery Mobile? I don't see the point in your current example.
In this case jQuery Mobile is the main problem. Because jQuery Mobile is used everything will be loaded into the DOM. When you "navigate from the previous page" page is not refreshed and this line:
google.maps.event.addDomListener(window, 'load', initialize);
can't trigger. It will trigger only if you manually refresh the page.
Second thing, you cant use jQuery Mobile page events without having any page what so ever. In your code you have this part:
$(document).delegate('#content', 'pageinit', function () {
navigator.geolocation.getCurrentPosition(initialize);
});
For it to initialize successfully div with an id content MUST have another attribute called data-role="page", like this:
<div id="content" data-role="page">
</div>
Third thing. Lets assume everything else is ok. Pageinit will not trigger from the HEAD. When jQuery Mobile loads pages it loads them into the DOM and only BODY part will be loaded. So for your map to work you need to move our javascript to the BODY (including a css). In you first example it didnt worked because you were triggering page even on a non-page div container.
And last thing, if you want to use jQuery Mobile properly you will need to take care correct version of jQuery is used with a correct version of jQuery Mobile. If you want to be safe use jQ 1.8.3 with jQM 1.2

Working examples and much more information regarding this topic can be found in this ARTICLE.
just add: data-ajax="false" to the link tag which redirects to the page that contains your map. for example, if map.aspx contains your map, you can link to it like this:
<a href="map.aspx" data-ajax="false">
I was having same problem but I have no any jquery-mobile libraray or any other which would conflict the map. Struggling a hard time, I found a solution for my project:
Doesn't work:
<script src="http://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" async defer>
</script>
Works (Removing async and defer attributes):
<script src="http://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
Hope! This helps someone if the other solutions doesn't work. Try this only if none of other solution work because it is not good suggestion as we know google page speed guide or google map api guide says to use it.
I have also same problem with
google.maps.event.addDomListener(window, 'load', initialize); where initialize is my method .
I just add few line of code before google.maps.event.addDomListener(window, 'load', initialize);
Code is
$(document).ready( function () {
initialize();
});
and this code is working for me
You should use the pageloadevent to load everything. This way everything is loaded once jquery Mobile has done all the DOM changes it needs. I've had this same problem and that's what helped.
$(document).on('pageload', function() {
initialize();
});
It's in the docs: http://api.jquerymobile.com/pageload/
EDIT: Sometimes it also helps to load the markers in a separate function than the one loading the map.
