用来设置在一个模型项以更新集合。如果找到任何新的模型,该项目将被添加到该模型。
collection.set(models,options)
<!DOCTYPE html>
   <head>

   <body>
      <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()));
      </script>
   </body>
</html>
