It All Starts With Templates

An Ember application starts with its main template. Put your header, footer, and any other decorative content in application.handlebars.

<header>
  <img src="masthead">
</header>

<footer>

var FormView = Backbone.View.extend({
  el: '#form',

  events: {
    // Fired automatically when a file-type input is detected with a
    // non-blank value. You can use this hook to implement a handler that
    // will deal with those non-blank file inputs. Returning false will
    // disallow standard form submission.
    'ajax:aborted:file'     : 'ajaxAbortedFile',
