I am send some data from php by json_encode to javascript. this is the data

[{"albumid":"ASaBFzCtl8","albumname":"anni","type":"3","access":"2","itemcount":"2"},{"albumid":"EmgsZ43ehT","albumname":"testalbum","type":"1","access":"1","itemcount":"0"},{"albumid":"Jf4H4SvFGk","albumname":"test2album","type":"3","access":"1","itemcount":"0"},{"albumid":"k3pacBSmIl","albumname":"testalbumpvt","type":"3","access":"2","itemcount":"0"}]

after enoding in php it is something like that

       //json_encode($data);

"[{\"albumid\":\"ASaBFzCtl8\",\"albumname\":\"anni\",\"type\":\"3\",\"access\":\"2\",\"itemcount\":\"2\"},{\"albumid\":\"EmgsZ43ehT\",\"albumname\":\"testalbum\",\"type\":\"1\",\"access\":\"1\",\"itemcount\":\"0\"},{\"albumid\":\"Jf4H4SvFGk\",\"albumname\":\"test2album\",\"type\":\"3\",\"access\":\"1\",\"itemcount\":\"0\"},{\"albumid\":\"k3pacBSmIl\",\"albumname\":\"testalbumpvt\",\"type\":\"3\",\"access\":\"2\",\"itemcount\":\"0\"}]"

i am receiving this in jquery

$.post("demo.php",
  {
    token:"123456789"
  },
  function(data,status){
    alert("Data: " + data + "
Status: " + status);
  });

what can i do so that i get all data in javascript array i need type value out of it and looking something like that

var typevalue = jsonArray['type'];
// typevalue = 3

Answer 1

Assuming you have parsed json here's how you loop it:

$.each(data, function(key, album){
    console.log(album.type);
});

To grab the first type in the list simply do:

var albumType = data[0].type;

Full solution with parsing:

$.post("demo.php", {
    token: "123456789"
},

function (data, status) {
    $.each(data, function (key, album) {
        alert(album.type);
    });

}, "json"); //datatype defined here
