This is your dataArray                  id  28         Title   Sweden                    id  56         Title   USA                    id  89         Title   England           Then parseJson can be used     jQuery parseJSON JSON stringify dataArray    each function           var ID   this id      var TITLE   this Title

Your question feels a little incomplete  but I think what you re looking for is a way of making your JSON accessible to your code   if you have the JSON string as above then you d just need to do this  var jsonObj   eval     id  28  Title   Sweden      id  56  Title   USA      id  89  Title   England         then you can access these vars with something like jsonObj 0  id etc  Let me know if that s not what you were getting at and I ll try to help   M

Swapnil Godambe It works for me if JSON stringfy is removed  That is     jQuery parseJSON dataArray   each function           var ID   this id      var TITLE   this Title

This isn t a single JSON object  You have an array of JSON objects  You need to loop over array first and then access each object  Maybe the following kickoff example is helpful  var arrayOfObjects         quot id quot   28     quot Title quot    quot Sweden quot          quot id quot   56     quot Title quot    quot USA quot          quot id quot   89     quot Title quot    quot England quot       for  var i   0  i  lt  arrayOfObjects length  i        var object   arrayOfObjects i     for  var property in object        alert  item     i          property         object property             If property names are known beforehand  you can also just do e g       alert object id         object Title      If the array of JSON objects is actually passed in as a plain vanilla string  then you would indeed need eval   here  var string       quot id quot  28  quot Title quot   quot Sweden quot      quot id quot  56  quot Title quot   quot USA quot      quot id quot  89  quot Title quot   quot England quot      var arrayOfObjects   eval string           To learn more about JSON  check MDN web docs  Working with JSON

By  JSON array containing objects  I guess you mean a string containing JSON   If so you can use the safe var myArray   JSON parse myJSON  method  either native or included using JSON2   or the usafe var myArray   eval       myJSON         eval should normally be avoided  but if you are certain that the content is safe  then there is no problem   After that you just iterate over the array as normal   for  var i   0  i  lt  myArray length  i          alert myArray i  Title
