   </head>
   <body>
      <script type="text/javascript">
      	//The model 'MyTeam' contains default values and extended using the Backbone.Model class
         var MyTeam = Backbone.Model.extend({
            defaults: {
               player: "Ganguly",
               country: "India"
            }
        });

        //The 'MyTeam1' is a collection instance and model 'MyTeam' is specified by overriding the 'model' property
        var MyTeam1 = Backbone.Collection.extend({
           model: MyTeam
        });
        var player1 = new MyTeam({
           player: "Dravid",
           country: "India"
        });
        var player2 = new MyTeam({
           player: "Tendulkar",
           country: "India"
        });

        //Passing the objects 'player1' and 'player2' to the collection
        var myval=new MyTeam1([player1,player2]);

        //The 'myval.models' define the array of models inside the collection
        document.write("The values of models in the collection are: "+JSON.stringify(myval.models));
      </script>
