How to parse JSON data with jQuery / JavaScript?

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) {            $('body').append($('<div>', {                text: element.name            }));        });    }});

or use the $.getJSON method:

$.getJSON('/functions.php', { get_param: 'value' }, function(data) {    $.each(data, function(index, element) {        $('body').append($('<div>', {            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

Try following code, it works in my project:

//start ajax request$.ajax({    url: "data.json",    //force to handle it as text    dataType: "text",    success: function(data) {        //data downloaded so we call parseJSON function         //and pass downloaded data        var json = $.parseJSON(data);        //now json variable contains data in json format        //let's display a few items        for (var i=0;i<json.length;++i)        {            $('#results').append('<div class="name">'+json[i].name+'</>');        }    }});
