How can I get the "name" attribute in node.js

Just use node-formidable for file uploads.

The right way in node.js is would be to use a web app framework like express. It gives you more options as well as flexibility. In express you can do :

var express = require('express');                     //Initialize express
var app = express();
app.listen(3000);

app.use(express.bodyParser());                        //to parse the forms
app.post('/pagesubmit', function(request, response){  //to handle POST to the page
  console.log(request.body.username);                 //tp access input text 'username'
  console.log(request.files.name);                    //to access input file 'name'
});
