要指定模型類,需要重寫的集合類的模型屬性。
Backbone.Collection.model
<!DOCTYPE html> <head> <title>Collection Example</title> <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script> </head> <body> <script type="text/javascript"> //The model 'MyTeam' includes default values and extended using the Backbone.Model class var MyTeam = Backbone.Model.extend({ defaults: { player: "sachin", country: "india" }, }); //'MyTeam1' is an instance of the collection var MyTeam1 = Backbone.Collection.extend({ model: MyTeam //model 'MyTeam'is specified for a collection by overriding the 'model' property }); //The collection 'MyTeam1' is instantiated by using new keyword var myval=new MyTeam1({}); //The JSON.stringify() method returns values of collection in the JSON format document.write("The values in the collection are: ",JSON.stringify(myval)); </script> </body> </html>
讓我們進行以下步驟來看看上面的程式碼工作:
儲存上述程式碼在檔案model.html
在瀏覽器開啟這個HTML檔案。
