Question

[
    [
        {
            "Id": 3,
            "Code": "232",
            "TicketImage": "0"

    [
        {
            "Id": 1,

            "TicketImage": "1"
        },

            "Id": 2,

            "TicketImage": "1"
        }
    ],
    []
]

I have this JSon object which I m trying to parse.

var res = jQuery.parseJSON(JSON.stringify(obj.Message));

              $.each(res, function (i, tickets) {
                  $.each(tickets, function (i, ticket) {
                      console.log($(this));
                  });
              });

When i try this i get zillions of popups with letters. but i want object.

How can i parse this JSON data?

UPDATE:

           $.each(res, function (i, tickets) {
                  $.each(tickets, function (i, ticket) { 
                      console.log(ticket.Code);
                      console.log(ticket.TicketImage);
                  });
              });

This did it.

$(this) will give you the object ? < inside the .each loop > unless I am missing something else :) hope this helps — Tats_innit

console.log(obj.message) to make sure the data is correct. then console.log(res) to make sure it parsed correctly. — Matthew Blancarte

Careful you are overriding the i variable :

$.each(res, function (i, tickets) {
                  $.each(tickets, function (j, ticket) {
                      console.log(this);
                      // as a full string
                      console.log(this.ticketId+' : '+JSON.stringify(this));

                  });
});

Besides this small thing, your loop is correct, you don't need the jquery wrapper on your 'this'. in $.each(array,function(k,v){}) , the k variable is the key to retrieve the current object and v it's value so you could also access it by doing this :

$.each(res, function (i, tickets) {
                  $.each(res[i], function (j, ticket) {
                      console.log(res[i][j].ticketId+' : '+res[i][j]);
                      // which is the exact same thing as :
                      console.log.(ticket);
                      // and even this:
                      console.(this);

                  });
});

The same code using 'this' :

$.each(res, function (i, tickets) {
                  $.each(this, function (j, ticket) {
                      console.log(this.ticketId+' : '+this);
                  });
});

using each value :

$.each(res, function (i, tickets) {
                  $.each(tickets, function (j, ticket) {
                      console.log(ticket.ticketId+' : '+ticket);
                  });
});

Try:

var res = jQuery.parseJSON(eval(obj.Message));
