Error in parsing JSON in Nodejs from Posted data

I have used this jquery ajax code to pass JSON:

var jsonObjects = [{id:1, name:"amit"}];

$.ajax({
 type: 'GET',
 url: 'http://localhost:8080',
 data: {
     jsonData: JSON.stringify(jsonObjects)
   },
   dataType: 'json',
   complete: function(validationResponse) {
  }
});

I have used this node js code to parse JSON data:

http.createServer(function (request, response) {
response.writeHeader(200, {
    "Content-Type": "text/plain"
});
 response.writeHead(200, {"Content-Type":"text/plain"});

  var theUrl = url.parse(request.url);
  var queryObj = queryString.parse( theUrl.query );
  var obj = JSON.parse( queryObj.jsonData);
  console.log(obj[0].id)
 response.write(String(obj[0].id))
   response.end();
}).listen(8080,'127.0.0.1');

but it displays following error in console:

undefined:1

Then the code stops..

This isn't a direct answer for your issue but I would suggest checking out Express and the bodyParser middleware.

They you can do something like:

var express = require('express');
var app = express();

app.get('/', function(req, res){
  console.log(req.query.jsonData);
  res.send('return data here');
});

app.listen(8080);

This section:

response.writeHeader(200, {
  "Content-Type": "text/plain"
});
response.writeHead(200, {"Content-Type":"text/plain"});

Seems garbled: is that your real code? If so, remove the first three lines. If that doesn't fix it, console.log request.url first, then queryObj.jsonData and see if they're reasonable.
