Node code:
var http = require(‘http’);
http.createServer(function (req, res) {

console.log(‘Request received’);

res.writeHead(200, {
‘Content-Type’: ‘text/plain’,
‘Access-Control-Allow-Origin’: ‘*’ // implementation of CORS
});
req.on(‘data’, function (chunk) {
console.log(‘GOT DATA!’);
});

res.end(‘{“msg”: “OK”}’); // removed the ‘callback’ stuff

}).listen(3004);
console.log(‘Server running at http://localhost:3004/‘);

html code:

response here: fill me in

$(document).ready(function() {
$.ajax({
url: ‘http://localhost:3004/’,
data: ‘{“data”: “TEST”}’,
success: function (data) {
alert(‘hi’);
var ret = jQuery.parseJSON(data);
$(‘#lblResponse’).html(ret.msg);
console.log(‘Success: ‘)
},
error: function (xhr, status, error) {
console.log(‘Error: ‘ + error.message);
$(‘#lblResponse’).html(‘Error connecting to the server.’);
},
});
});

Thanks.
