Sinatra / Padrino partials with modal window

Question

A modal window is generally done using javascript. For example, using jQuery UI (from the docs)

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.1/themes/base/jquery-ui.css" />
  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  <script src="http://code.jquery.com/ui/1.10.1/jquery-ui.js"></script>
  <link rel="stylesheet" href="/resources/demos/style.css" />
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>


</body>
</html>

Sinatra/Padrino will take care of the layout and the view, you just have to add the script portion. Assuming you're using Haml, your view would look like this:

#dialog{title: "Basic dialog"}
  %p
    This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.

:javascript
  $(function() {
    $( "#dialog" ).dialog();
  });

The javascript doesn't need to go inside the head tags as the jQuery docs suggest.

Edit:

There are a couple of choices for loading a partial into a window. One is to use a javascript library like Handlebars, but I prefer to get the javascript to load it from a route, that way all the view code stays together, e.g.

get "/templates/modal1/?" do
  haml :modal1, :layout => !xhr?
end

In the javascript, make an AJAX call to that route and you'll get only the HTML sans the layout, then use it to fill the box:

$.get('ajax/test.html', function(data) {
  $('#dialog').html(data);
}

and in your view just describe the div:

#dialog1
  -# The HTML from the view will be put here by the jQuery code.

Something like that.
