Answer 1

Thats because json variable contains an json object instead of a json string. when you change it to a string, everything works as expected.

var jsonStr = '{"result": "success"}';
var ajaxres = JSON.parse(jsonStr);
console.log(ajaxres.result);

var json = {
  "result": "success"
}
console.log(json.result);

<div></div>

Answer 2

That's because you are trying to parse a JavaScript object, not a string. You should either do:

var json = '{"result":"success"}';
var ajaxres = JSON.parse(json);
console.log(ajaxres.result);

OR

var json = {"result":"success"};
console.log(json.result); // json["result"] will give you the same result.

Answer 3

You don't need to parse a Javascript Object again using JSON.parse.

If you have a JSON string only then use JSON.parse() , like below

JSON.parse('{"result":"success"}')

Answer 4

If you want that variable json to hold a JSON string, you have to do

var json  = '{"result":"success"}'
var ajaxres = JSON.parse(json);
console.log(ajaxres.result)

I also fixed your typo: result instead of resut.

Answer 5

JSON.parse() converts any JSON String passed into the function, to a JSON Object.

var response = '{"result":"success"}'; //sample json object(string form)
JSON.parse(response); //converts passed string to JSON Object.

But your JSON response if already parsed. So, use DOT(.) to access your key-value

Answer 6

First you need to store json as a string. Then that string should be converted to javascript object. Then It should be printed.

var json  = '{"result":"success"}';
var ajaxres = jQuery.parseJSON(json);
console.log(ajaxres.result);
