38 The template starts out by defi ning the text input fi eld where the user can input the name of the new note along with a button that the user can click to create the new note. Both the text fi eld and the button will fi re the action createNewNote, which will be called either when the user hits the carriage return key inside the text fi eld, or when the button is pressed. Further, the value of the text fi eld is bound to the controller.newNoteName property via the valueBinding attribute. In fact, whenever a property or a template attribute ends with the keyword Binding, Ember.js will set up a two-way binding in order to keep data in sync between layers within your application, even all the way out to the view. You might be wondering how our Notes application knows when and which note to display, and the secret to this lies in the NoteListItemView. Notes.NoteListItemView = Ember.View.extend({ click: function() { this.get('controller').set('selectedNote', this.get('content')); } }); I have omitted most of the code in this view. Each Ember View will inherit either directly or indirectly from the Ember. View class bringing with it a slew of nice functionality, one of which is event handling. The NoteListItemView is listening for the click event, which will update the selectedNote property on its controller whenever the view is clicked upon with the mouse. At this point, the only thing missing is the selectedNote template. Ember.TEMPLATES['selectedNote'] = Ember.Handlebars.compile('' + '{{#if controller.content}}' + '{{name}}' + '{{view Ember.TextArea valueBinding="value"}}' + '{{/if}}' ); As you can see the selectedNote template will only render if its controller (the SelectedNoteController) has a content, and it will render a simple headline and a text area inside which it will bind the contents the selected note. In this article we have blazed through some of the building blocks of an Ember.js application, but it should be enough to get you up and running. The code sample, the Notes application, is adapted from the fi rst chapter of the book ”Ember.js in Action”, which I am currently writing. The book will be published by Manning Publications in the third quarter of this year, but rest assured, you will be able to get early access to the chapters from mid february as they are being written, exclusively through the books website at http://manning.com/skeie/.

Ember.js Joachim is the author of "Ember.js in Action", published by Manning Publications. He works as an independent consultant through his company Haagen Software AS and has worked with various web technologies since 2006, ranging from JavaServer Pages, JavaServer Faces, SproutCore to Ember.js. He have been the technology lead for norways largest retail application (measured in volume) and know the pains that server–side generated markup and scripts can cause while trying to scale out a service. He fi nally saw the light when he discovered SproutCore in 2009. When Ember.js broke out of the SproutCore community, he knew this was the way to build web applications for the future!
