EmberJS- Manually Managing View Hierarchy

Manually Managing View Hierarchy

You can also manage views manually by using Ember.ContainerView and it programmatically adds and removes the views.

var VarName = Ember.ContainerView.create();

Example

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Manually Managing View Hierarchy</title>

         <h2>Handling Child View</h2>
         <button>{{#view 'child'}}Click Me{{/view}}</button>
      </script>

      <script type="text/javascript">
         //declaring App as ContainerView object
         App = Ember.ContainerView.create();

         App.BaseView = Ember.View.extend({
            click: function() {
               document.write("<b>Main View");
               //calling child view
               this.send('wat');
            }
         });

         App.ChildView = App.BaseView.extend({
            //child view extended by base view
            actions: {
               wat: function() {
                  document.write("<br><b>Child View");
               }
            }
         });
      </script>
