I am wondering how can I parse Array of JSON objects in NodeJS?

I want to post JSON array to the server, and be able to use the received array as a regualar JavaScript array.

Thanks in advance.

This is my front-end part that I am converting Array to String using stringify function

document.getElementById(sendJson).addEventListener(click, function () {

    $.post(/echo, JSON.stringify(QuestionsArray), function (data) {

        alert(data);

    });

})

This my back-end part that I am trying to convert Array of JSON object to Array

app.post('/echo', function (req, res) {

    var Array = JSON.parse(JSON.stringify(req.toString()));

    res.end(Array[0][QuestionText].toString());

});

This is Array that I am trying to sent to the server:

[  

   {  

      QuestionText:What is your Name,

      QuestionType:1

   },

   {  

      QuestionText:Where are you from,

      QuestionType:2,

      ChoiceList:[  

         US,

         UK

      ]

   },

   {  

      QuestionText:Are you married,

      QuestionType:3,

      ChoiceList:[  

         Yes,

         No

      ]

   }

]

Here is the source code

In your app.js:

var bodyParser = require(body-parser);

...

app.use(bodyParser.urlencoded({extended: true}));

Then you can just use req.body to get the posted values:

app.post('/echo', function (req, res) {

    var Array = req.body.data;

    res.end(Array[0][QuestionText].toString());

});

In front-end, don't do any stringifying:

$.post(/echo, {data: QuestionsArray}, function (data) {

    alert(data);

});
