JSON.stringify（data）填充变量

Question

I have data from my model coming back to me. In the past i have used

$.parseJSON(data); 

This I would then use $.each and loop through the data and output arrays into tables rows/columns.

Instead what I want to do is have a number of variable in which I can decide whether to set to value of a textbox or div or any element

I was seeing this JSON.stringify and wondered about if it is more practical in that it is putting the data into a string, except I wasn't sure HOW to really use it.

JSON.stringify(data)

Example:

<li><a href="#">USERID</a></li>

OR

<input type=text id="whatever">

I can see in chrome dev tools output of data is

Object {ntid: "bthorn", AuthGroup: "admin", DOCCCOGroup: "sst"}

What is the easiest way to JUST get that "ntid" value?

var ntid = data["ntid"] ???   

Answer 1

alert(data.ntid)

DEMO

Use the key of the value you want to get

Answer 2

$.parseJSON is the same as JSON.parse not JSON.stringify the former parses a JSON string into a javascript object, the latter converts a javascript object into a JSON string.

And answering your question you could access using data.ntid or data["ntid"]

var json = '{ "foo": "bar", "test": "stack" }';
var obj = JSON.parse(json); // obj = { foo: "bar", test: "stack" };

var obj = { foo: "bar", test: "stack" };
var json = JSON.stringify(obj); //'{ "foo": "bar", "test": "stack" }'
