<script type="text/javascript">
//Here the model name is 'Player' and contains default value
var Player = Backbone.Model.extend({
defaults: {
name: 'sachin'
},
});
//'PlayersCollection' is an instance of collection
var PlayersCollection = Backbone.Collection.extend({
model: Player //model 'Player' is specified by using model property
});
var player1 = new Player({ name: "dhoni" }); //'player1' is instance of the model
var mycollection = new PlayersCollection(); //'mycollection' is instance of the collection
mycollection.add(player1); //adding model instance 'player1' along with value to the collection
//The set() method update the 'player1' model by passing this value in the collection
mycollection.set([player1, { name: "raina" }]);
document.write(JSON.stringify(mycollection.toJSON()));
