如何访问Json对象的元素？ [英] How to access element of a Json Object?

问题描述

我正在将DataSet转换为Json，它看起来像这样（客户端的data.d返回给客户端）

I am converting DataSet to Json which looks like this (data.d at clientside which is returned to client)

{"patients":[{"name":"sam","id":"1"},{"name":"mark","id":"2"}],"medications":[{"id":"1","medication":"atenolol"},{"id":"2","medication":"amoxicillin"}]}

现在我是试图在变量中获取患者数据表，但我无法这样做。

我试过

Now I am trying to get Patient datatable in a variable but I am unable to do so.
I tried

var dt=data.d;

但

But

dt['patients'] 

给我解开。

推荐答案

嗨Arbaaz，



实际上它是一个JSON对象而不是一个数组所以你必须使用以下内容：

Hi Arbaaz,

Actually it is a JSON object not an array so you have to use following:

//First convert your response in JSON object
var dt = JSON.stringify(data.d);

//Now you can access Patients name like
alert(dt.patients[0].name) // it will popup "sam"

谢谢，
