In the markup below, I want to set the container property of the MapView to the <div> with an Id = "viewDiv". When I remove the outer <div> with the Id = "container" everything works and a map appears. When I run using the outer container <div>, the map does not appear. How do I set the container property to the inner <div>?

The reason it works if you remove the outter div is because the inner div has a height of 100% of the window. But with the outter div the the inner div has a height of 100% of nothing (the height specified for the outter div). So give the outter div a height.
#container {
height: 100%
}

I'm using MapBox on my application and i would like to know how can i display lat and lng inside div element after i select an address from a list that are display inside a div? My reference is this MapBox page https://docs.mapbox.com/mapbox-gl-js/example/mapbox-gl-geocoder-no-map/, but i didn't find a correct way to do that using javascript.
To explain more clearly my doubt, below are the code that i'm using on my application and i would like to display lat and lng inside "latitude" and "longitude" div's as below if is possible:

In this case, how can i improve the code above to display latitude and longitude informations inside a div after select a value inside geocoder div?
If I'm understanding you well, what you want is basically capture the result selected in the geocoder and paint the coordinates of the result in a div. For that, you need to subscribe to the result event.
For that, you need to add the event listener like this, and there paint the result in the inner HTML of the div:
geocoder.on('result', function(r) {
console.log(r);
document.getElementById("coords").innerHTML = r.result.center;
})
I have created a fiddle on how to subscribe to result selected on geocoder

everyone, I have uploaded my google map KML file to my website then I have used google map javascript API key. if you notice once you run the map you will see all my markers in white( transparent ) is there a way to have my map exactly the same way like I had it before saving. the code below, Thank you in advance:

I am very new to JS and HTML so please bear with me.
I have a static image (in .jpg format) which is a kind of diagram containing 32 different circles. They are each numbered 1 - 32 however I am not able to manipulate the image in the sense that I cannot move the circles or change the numbers inside of them.
For the sake of simplicity, I have included an image below containing circles - this represents the image that I have.
My first objective is to make this image a thumbnail that, when clicked, expands to cover most of the page.
The following JQuery code serves this purpose:
$("#thumbnailImage").click(function() {
$(this).attr('width', '400');
$(this).attr('height', '300');
I have inserted this into my code:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8' />
<title></title>
<meta name='viewport' content='initial-scale=1,maximum-scale=1,user-scalable=no' />
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<script type="text/javascript">google.load("jquery", "1.3.2");</script>

<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.15.0/mapbox-gl.css' rel='stylesheet' />
<style>
body { margin:0; padding:0; }
#map { position:absolute; top:0; bottom:0; width:100%; }
#panel{ position: absolute; bottom: 10px; right: 10px; z-index: 1010101; display: block; width: 400px; height: 400px; overflow-y: auto; background: rgba(255,255,255,0.1); color: white;}
</style>
</head>
<body>
<div id='map'></div>
<div id = 'panel'>
<img id = "thumbnailImage" src="http://iskandarblue.github.io/mapbox/data/circles_page.jpg" width="350" height="250" alt="circles"/>'
</div>
<script>
mapboxgl.accessToken = 'pk.eyJ1IjoiaXNrYW5kYXJibHVlIiwiYSI6ImNpazE3MTJldjAzYzZ1Nm0wdXZnMGU2MGMifQ.i3E1_b9QXJS8xXuPy3OTcg';
var map = new mapboxgl.Map({
container: 'map', // container id
style: 'mapbox://styles/mapbox/dark-v8', //stylesheet location
center: [-74.50, 40], // starting position
zoom: 9 // starting zoom
});
$("#thumbnailImage").click(function() {
$(this).attr('width', '400');
$(this).attr('height', '300');
});
</script>
</body>
</html>
In this example, the image expands in the wrong direction (it expands outward rather than inward), and does not collapse again when clicked twice. Is there an easy way to fix this ?
Now, once the image has expanded, I would like the user to be able to hover over a circle and see a popup text much like what the tipsy jQuery plugin does (see here): http://onehackoranother.com/projects/jquery/tipsy/
I am not sure how to proceed or how to conceptualize the problem. What's the easiest way to assign pop-up functions to circles on a static image and how can these popups (or tooltips) be activated only when the image is in expanded mode? Any advice would be appreciated.
I need to create a layout with a "menu" sort of thing on the left, and on the right load a the world map. In the left menu I will have a tree, with checkboxes on the leaves. Each leave is a tile that will be loaded on it's position when the checkbox is selected. Let's say on the tree I have as parents USA and Canada. Under USA I have New York Buildings, New York Streets, Washington Buildings, and under Canada something similar. When I check New York Buildings, I need to load that tile over the map and center the map to that tile. When I click New York Streets I need the other tile to be put over this first one(it will have transparency). And so on. The main idea is that I cannot center the map to the location of the tile. Haven't tried the rest, this is where I am stuck. My code:
#{
ViewBag.Title = "Map";
Layout = "~/Views/Shared/_Layout.cshtml";
}

data-dojo-type="dijit.layout.BorderContainer"
data-dojo-props="design:'headline', gutters:false"

this is how I found that one centers the map. But I would like to center it to the loaded tile. Also, can the folder structure with the tiles (http://xx.xxx.xx.xx:xxxx/arcgis/rest/services) loaded in a tree?
The map object has several methods for displaying a particular view, be it centring on a MapPoint or other geometry. For example, you could use Map.centerAt(mapPoint) if you had a map point. What you want to do is centre on the extent of the tiled map service you've loaded so you can use map.setExtent(extent, fit) passing it the extent of the tiled service and the Boolean fit if you want it to zoom as required to fit the whole extent. You can get the extent of the tiled service using TiledMapServiceLayer.fullExtent property. For example:
map.setExtent(tiled.fullExtent, true);
You can subsequently put this into your check box event function so that every time it's checked it zooms to the extent (if that's how you want it to behave, another option might be to have the checkbox click event just toggle the layers visibility but then have a 'goto' button next to it that zooms to it).
You can check out more documentiontation for the map object and all of the ArcGIS API here: https://developers.arcgis.com/javascript/jsapi/map-amd.html
Hope this helps.
Edit:
As per your comment, trying to access the fullExtent property straight after the call to load the layer doesn't work because addLayer is asynchronous and so execution returns before the layer is loaded. To set the extent straight as soon as the layer is loaded, you need to register a function to run when the layers onLoad event is raised. The following code should achieve this:
var tiled = new Tiled("http://xx.xxx.xx.xx:xxxx/arcgis/rest/services/USA/NewYork_tiles/MapServer");
tiled.on("load", displayLayerExtent);
map.addLayer(tiled);
function displayLayerExtent(evt) {
map.setExtent(evt.layer.fullExtent, true);
}
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
