backbone.js集合fetch backbone.js集合fetch|Backbone.js教程

本文概述

参数说明

Backbone.js集合的获取方法用于使用sync方法获取集合中的默认模型集。
句法：

collection.fetch(options)

参数说明选项：它指定“成功”或“错误”回调，它们都将作为参数传递。
让我们以一个示例来部署fetch方法。
请参阅以下示例：

< !DOCTYPE html> < head> < title>Fetch Collection Example< /title> < script src="http://img.readke.com/220416/06101B632-0.jpg" type="text/javascript">< /script> < script src="http://img.readke.com/220416/06101B3T-1.jpg" type="text/javascript">< /script> < script src="http://img.readke.com/220416/06101B017-2.jpg" type="text/javascript">< /script> < /head> < body> < script type="text/javascript"> //The sync() method represents state of a model Backbone.sync = function(method, model) {//The 'method' gives 'read' state of the model by representing data in JSON format document.write("The fetched details are: ", method + ": " + JSON.stringify(model)); }; //The collection instance 'details' contains the values which are to be fetched in the collection var details = new Backbone.Collection({ Name:"Narendra Modi", Country:"India" }); //This will display the model state by delegating the 'sync()' method details.fetch(); < /script> < /body> < /html>
