How to parse data from Json Result in Jquery Ajax?

Question

I am getting Json Data from WCF service. But I unable to extract/parse data in Jquery Ajax Call?

 

Ajax:

$.ajax({

type: 'GET',

contentType: 'application/json; charset=utf-8',

url: './Services/Service.svc/GetUserDetails',

data: { uname: 'e0205' },

async: false,

dataType: 'json',

success: function (response) {

//var testMsg = $.parseJSON(response);

alert(response.GetUserDetailsResult);

},

error: function (error) {

alert(error);

}

});

 

Json Data :

 

{"GetUserDetailsResult":"{\"Table\":[{\"UserName\":\"E0205\",\"EmpName\":\"Manjeet\",\"LocationName\":\"Gurgaon\",\"Designation\":\"Analyst\"}]}"}

 

Kindly suggest any possible ways. Thanks in advance.
