主要成分：从JSON创建集合 [英] Backbone: Create collection from JSON

问题描述

我试图加载JSON（从PHP的json_en code）成骨干JS集合。我已经简化了问题：

I'm attempting to load JSON (from php's json_encode) into a Backbone JS collection. I've simplified the problem to:

var myJSON = '[{ "id":"1","name":"some name","description":"hmmm"}]';

var myCollection = new MyCollection(myJSON, { view: this });

和

MyObject = Backbone.Model.extend({

  id: null,
  name: null,
  description: null
});

MyCollection = Backbone.Collection.extend({ 
model: MyObject,
initialize: function (models,options) { }
});

错误：

未捕获类型错误：在运营商不能使用

Uncaught TypeError: Cannot use 'in' operator to search for 'id' in

类似的问题：骨干：从服务器上获取集合

我的JSON肯定似乎是在正确的格式，我失去了一些东西明显？我一直在使用简单的ID企图：1，而不是ID具有相同的结果。

My JSON certainly appears to be in the right format, am I missing something obvious? I have attempted using simply id: "1" as opposed to "id" with the same result.

推荐答案

您JSON仍处于字符串格式。分配前将它传递给JSON.parse：

Your JSON is still in string format. Pass it to JSON.parse before assigning it:

var myJSON = JSON.parse('[{"id":1,"name":"some name","description":"hmmm"}]');
