I'm confused as to where exactly place the script tags in my Rails app to have a Google map embed in a page. I'm following the directions from the Google API https://developers.google.com/maps/documentation/javascript/tutorial
The code looks like this:
<!DOCTYPE html>
<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=AIzaSyAK04aYSxZArPElFFZfo3o2p-CbviPzfhc&sensor=false">
</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>
<body>
<div id="map-canvas"/>
</body>
</html>
I'm placing the first script tag within my application.html.erb file like so:
<%= javascript_include_tag "https://maps.googleapis.com/maps/api/js?key=AIzaSyAK04aYSxZArPElFFZfo3o2p-CbviPzfhc&sensor=false" %>
I have a Venue model and a venues controller.
I want the map to appear in the Venues show action. So I place the second script inside venue.js. My show.html.erb looks like this:
<div class="center">
<h1><%= #venue.name %></h1>
<address><%= #address %></address>
<div id="map-canvas"/>
</div>
But no map appears when I load this page.
A very easy way to do this is to simply embed the map in an iframe. Using .haml for markup,
%iframe.google-location{ frameborder: '0', scrolling: 'no', src: 'https://www.google.com/maps/embed/v1/place?q=place_id:{google_generated_placeId}' }
the class 'google-location' (or whatever you want to name it) only needs to have the size of the iframe.
(make sure to have a valid api key)

I am trying to load an ESRI Tile Layer within an HTML page but for some reason the map isn't displaying.
It should be a straightforward process and I cannot identify what the issue is (I receive no error messages within the console window).
Any suggestions?

Because your imports order is wrong. You should change this line
function(TileLayer, Map, MapView)
to
function(Map, MapView,TileLayer) {

The following code builds 3 datagrids, 2 via markup and one via code.
When you press the "autoheight!" button only the markup datagrids resize.
I don't understand why the code datagrid does not work. As far as i can see, the same attributes are being initialized.
Thanks

again, dojo is a horrible tool. going to datatables (jquery plugin). the sun shines again.
Hi I have a simple one as shown below that displays bordercontainer and contentpane.
I do not understand why the bordercontainer's id is registered twice since I only have one
id defined for bordercontainer.
The error stated: Error: Tried to register widget with id==main_bContainer but that id is already registered
Please advise where I got it wrong.

Becuase you have parse() its 2 times.
Here dojoConfig = { parseOnLoad: true };
and here parser.parse();
Just parse only one the problem will solve.
I have downloaded dojo build, now I have an doubt, in the below example code, I am using "dojo.js.uncompressed.js" as a start of source file, is it right? Just I want to display a button in the web page. Which one is the start file? in dojo library.

dojo (and any js file) should be put next to your html files so that it is served by the server. Then you don't have to relate to long relative paths
I copied an example from the dojo site using Borderlayout. However, when I load in the browser , the entire data is shown for all the section . Then after a few second the content is refersh and the data is displayed correctly.
here is code that i copied . Thanks for your help

This looks a bit upside down : you should put your javascripts in the head section and load the dojo libraries in first place. That's not your problem though.
What happens is that when the page loads, dojo loads all the modules that you "dojo.require", then parses all your tags containing the attribute "dojoType" and processes them for rendering, and this takes time.
So the flickering that you're seeing is the difference between the page before and after the widgets are parsed.
You should add a preloader div and hide it once the page is parsed (see this example).
This is what it would look like for your example :
<html>
<head>

disable parseOnLoad and manually add event to parse widgets for ie.
