• Felix Kling: Parse the JSON into a JavaScript object and extract the desired data. Read Working with Objects if you don't know how to access properties of objects (JavaScript basics).
• watraplion: I tried var obj = jQuery.parseJSON(JSON); It showing Object expected. But i tried with double quotes.
• watraplion: this is working obj = JSON.parse(json); Thank you Felix and you all.

Answer 1

First of all, if you execute the JSON variable you have there, should give you a syntax error because you need to escape the double quotes, such as:

var JSON = "{ \"UserID\":\"1\",\"ClientID\":\"1\",\"UserName\":\"User1\"}";

or simply use single quotes to create the string

var JSON = '{ "UserID":"1","ClientID":"1","UserName":"User1"}';

Then you can just parse it using jQuery.parseJSON()

var obj = jQuery.parseJSON(JSON);
obj.UserID == 1; // true

Answer 2

Be wary of unescaped quotation marks in that string. I changed the outer quotes to single quotes.

var obj = jQuery.parseJSON('{ "UserID":"1","ClientID":"1","UserName":"User1"}')
var UserID = obj.UserID 
var ClientID = obj.ClientID
var UserName = obj.UserName
