Question

嗨获取具体的数据，我有以下的JSON：

[ 
    {"id":"1","question":"Whats is your name ?","type":"Text","source":"-","default":"-","control":"-","requestDate":"Yes","required":"Yes"}, 
    {"id":"2","question":"What is your Age ?","type":"Text","source":"-","default":"-","control":"-","requestDate":"No","required":"No"}, 
    {"id":"3","question":"What is your interest?","type":"Text","source":"-","default":"-","control":"-","requestDate":"Yes","required":"No"},

    {"id":"5","question":"What is your Nic ?","type":"Text","source":"-","default":"-","control":"-","requestDate":"Yes","required":"No"} 
] 

现在我来从JSON，我希望获取由id参数数据，其ID获取过程中提供的数据。例如提取结果提供了json对象

​​

如果我在collection.fetch事件中提供id = 1 ..任何方法？

Answer 1

如果你在Backbone Collection中有这个JSON。您可以通过传入id，cid或Model对象来获取特定的模型。在你的情况

myModel = collection.get(1); 

其中collection应该是无论你的集合实例是

Answer 2

如果我正确理解你的问题，你正在寻找：

collection.fetch({ data: $.param({ id: 1}) }); 

你必须添加一些代码服务器端。

Answer 3

如果你把所有的JSON数据已经，并希望过滤它只是一个匹配的记录，你可以使用findWhere：

myModel = collection.findWhere({id: 1});
