backbone.js集合create backbone.js集合create|Backbone.js教程

本文概述

参数说明

Backbone.js集合的create方法用于在集合中创建模型的新实例。
句法：

collection.create(attributes, options)

参数说明属性：它指定已定义模型的属性。
【backbone.js集合create】options：它指定参数（例如id，name等）来创建集合实例。
让我们以一个示例来部署create方法。
请参阅以下示例：

< !DOCTYPE html> < head> < title>Create Collection Example< /title> < script src="http://img.readke.com/220416/06102SP0-0.jpg" type="text/javascript">< /script> < script src="http://img.readke.com/220416/06102V030-1.jpg" type="text/javascript">< /script> < script src="http://img.readke.com/220416/06102SP7-2.jpg" type="text/javascript">< /script> < /head> < body> < script type="text/javascript"> //The model 'ModelDemo' uses the sync method to display the model state such as create, read, update etc var ModelDemo = Backbone.Model.extend({ sync : function (method, model, options) { document.write(JSON.stringify(arguments)); } }); //'CollectionDemo' is an instance of the collection var CollectionDemo = Backbone.Collection.extend({ model : ModelDemo//The model 'ModelDemo' is specified by overriding the 'model' property }); //'ViewDemo' is the name of the view var ViewDemo = Backbone.View.extend({//The instance of the collection 'collectiondemo' is created within the 'initialize()' function initialize : function () { var collectiondemo = new CollectionDemo(); collectiondemo.create({ Name:"Narendra Modi", Country:"India" }); } }); new ViewDemo(); //The view instance 'ViewDemo' is created using the 'new' keyword. < /script> < /body> < /html>

输出：
将以上代码保存在create.html文件中，然后在新的浏览器中打开该文件。
