Assuming your server side script doesn t set the proper Content-Type  application json response header you will need to indicate to jQuery that this is JSON by using the dataType   json  parameter   Then you could use the   each   function to loop through the data     ajax        type   GET        url   http   example functions php        data    get param   value          dataType   json       success  function  data               each data  function index  element                   body   append     lt div gt                      text  element name                                          or use the   getJSON method     getJSON   functions php     get param   value     function data          each data  function index  element               body   append     lt div gt                  text  element name

Setting dataType  json  will parse JSON for you     ajax     type   GET     url   http   example functions php     data   get param   value      dataType   json     success  function  data        var names   data         cand   html data             Or else you can use parseJSON   var parsedJson     parseJSON jsonToBeParsed     Then you can iterate the following   var j      id   1   name   test1     id   2   name   test2     id   3   name   test3     id   4   name   test4     id   5   name   test5           by using     each   var json     parseJSON j     json  each function  i  val        each val  function  k  v        console log k           v                JSFiddle

I agree with all the above solutions  but to point out whats the root cause of this issue is  that major role player in all above code is this line of code   dataType  json    when you miss this line  which is optional   the data returned from server is treated as full length string  which is default return type   Adding this line of code informs jQuery to convert the possible json string into json object   Any jQuery ajax calls should specify this line  if expecting json data object
