Understanding Ember.Object

Almost every object in Ember.js is derived from a common object: Ember.Object. This object is used as the basis for views, controllers, models, and even the application itself. This simple architectural decision is responsible for much of the consistency across Ember. Because every object has been derived from the same core object, they all share some core capabilities. Every Ember object can observe the properties of other objects, bind their properties to the properties of other objects, specify and update computed properties, and much more. As you'll see in this post, it's easy to get started with Ember.Object, but also easy to overlook some of its capabilities. Creating objects It's almost as simple to create a new Ember.Object as a plain Javascript object: The object literal that is optionally passed to Ember.Object.create() defines properties directly on the instantiated object, not unlike the vanilla object. Extending classes Now, let's instantiate a person with create():

Ember.js Router Action to Controller ejemplo slide fotos Writing an Ember.js App From Scratch (Part 2) | Drew Schrauf In part 1 of this tutorial we began to make a very simple todo app which used Ember to handle all of the logic. If you haven't read it yet, check it out! Our little todo app is now displaying a couple of prepopulated Todo items with a little counter at the bottom that shows the number of incomplete items. Obviously, a todo app isn't very useful if you can't add your own items to it so that's what we'll dive into next. As before, our controller is where all of our business logic should be sitting so we'll start by adding a method to our controller which will add a new item to our list. The function createTodo that we've defined here doesn't really do anything special. If you remember the Ember.Checkbox we used in part 1 to bind a Todo's properties to a view, you can probably guess at where we're going next. All we've done here is override the insertNewline method of Ember's TextField to make it call the createTodo method we defined earlier if the user has entered a value. …into this:

Getting Started With EmberJS - andy matthews JavaScript heavy applications can be found all over the place these days. As JavaScript applications become more and more complex, it's no longer acceptable to have a long chain of jQuery callback statements, or even distinct functions called at various points through your app. JavaScript developers are slowly learning what traditional software programmers have known for decades. I consider myself a pretty good developer...by no means the best, but I'm skilled at taking existing technologies and forging them into something unique and of my own creation. One of the drawbacks of Ember over Backbone is that the latter has a wealth of tutorials, articles, and Github projects while the former has very little available material. Ember.js is an MVC (or Model View Controller) style framework which simply means that it offers you the ability to break out your code into 3 distinct types of pieces. M = Model - The Model is like a cookie jar. Let's get started shall we? Congratulations!

Flame on! A beginner's guide to Ember.js Sophisticated JavaScript applications can be found all over the place these days. As these applications become more and more complex, it's no longer acceptable to have a long chain of jQuery callback statements, or even distinct functions called at various points through your application. This has led to JavaScript developers learning what traditional software programmers have known for decades: organization and efficiency are important and can make the difference between an application that performs great and one that doesn't. One of the most commonly used architecture patterns to achieve this organization and efficiency is known as Model View Controller (or MVC). This pattern encourages developers to separate distinct parts of their application into pieces that are more manageable. In this tutorial you'll become more familiar with the basics of Ember.js as you build a working Twitter timeline viewer. Ember has only one dependency—jQuery.
