I am unable to iterate the following JSON as I am expecting. The code is given as below :

$(document).ready(function() {

    var data = '{employees:n

                [{908887 : {firstName:John, lastName:Doe}},n

                 {98764 : {firstName:Anna, lastName:Smith}},n

                 { 98762 : {firstName:Peter, lastName:Jones}}]}';  



    var empObj = JSON.parse(data);

    for(var key in empObj.employees){

        alert('key - ' + key + '  value - ' + empObj.employees[key]);

    }   

});

In alert, I am getting the keys 0, 1, 2, but I want: 908887, 98764, 98762. I also want to iterate over the values.

Please tell how to solve the issue.

This should do it:

var data = '{employees:n

  [{908887 : {firstName:John, lastName:Doe}},n

   {98764 : {firstName:Anna, lastName:Smith}},n

   { 98762 : {firstName:Peter, lastName:Jones}}]}';  





var empObj = JSON.parse(data);



empObj.employees.forEach((item) => {

  Object.entries(item).forEach(([key, val]) => {

    console.log(`key-${key}-val-${JSON.stringify(val)}`)

  });

});
