    str += chunk;
  });
  response.on('end', function () {

http.request(options, callback).end();

Answer 1

You should use POST request, because form tag contain method attribute

 <form id="frmThis" name="frmThis" method="post" action="">

Try this code:

var querystring = require('querystring');
var http = require('http');

var post_data = querystring.stringify({
    txtSearch: "17051017387"
})

var options = {
    host: 'nbr.gov.bd',
    path: '/getbinfield.php',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': post_data.length
    }
};

callback = function(response) {
    console.log(arguments);
    var str = '';
    response.on('data', function (chunk) {
        str += chunk;
    });
    response.on('end', function () {
        console.log(str);
    });
}

var req = http.request(options, callback)
req.write(post_data)
req.end()

Using the request module:

var request = require('request')
request.post('http://nbr.gov.bd/getbinfield.php', {
  form: {
    txtSearch: '...search for something',
    bthSubmit: 'Search'
  }
}, function (err, res, body) {
  console.log(body)
})
