JavaScript MVC Örnek

Öncelikle Sayfamıza button ekliyoruz id'si "add-friend" olarak tanımlıyoruz. Daha sonra girilen verilerin gösterimin yapılacağı bir list tanımı yapıyoruz id'si "friends-list" atamasını yapıyoruz.

sayfamıza aşağıda yer alan jsicript kütüphanelerini ekliyoruz :
script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"
script src="http://ajax.cdnjs.com/ajax/libs/underscore.js/1.1.4/underscore-min.js"
script src="http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js"


Javasipt Kodu :

(function ($) {
 
  Friend = Backbone.Model.extend({
    //Create a model to hold friend atribute
    name: null
  });
 
  Friends = Backbone.Collection.extend({
    //This is our Friends collection and holds our Friend models
    initialize: function (models, options) {
      this.bind("add", options.view.addFriendLi);
      //Listen for new additions to the collection and call a view function if so
    }
  });
 
  AppView = Backbone.View.extend({
    el: $("body"),
    initialize: function () {
      this.friends = new Friends( null, { view: this });
      //Create a friends collection when the view is initialized.
      //Pass it a reference to this view to create a connection between the two
    },
    events: {
      "click #add-friend":  "showPrompt",
    },
    showPrompt: function () {
      var friend_name = prompt("Who is your friend?");
      var friend_model = new Friend({ name: friend_name });
      //Add a new friend model to our friend collection
      this.friends.add( friend_model );
    },
    addFriendLi: function (model) {
      //The parameter passed is a reference to the model that was added
      $("#friends-list").append("
  • " + model.get('name') + "
  • ");
          //Use .get to receive attributes of the model
        }
      });
     
      var appview = new AppView;
    })(jQuery);
