var Upload = (function(win, upload) {

  upload.submit = function() {
    var self = this,
      form = document.getElementById('form'),
      formdata = new FormData(form),
      xhr = new XMLHttpRequest();

FormData，这是另一种针对 XHR2 设计的新数据类型。使用 FormData 能够很方便地实时以 JavaScript 创建 HTML <form>。

var fs = require('fs'),
  formidable = require('formidable');

app.post('/upload', function(req, res) {
  var form = new formidable.IncomingForm(),
    data;

  // formidable 属性设置可以参考 github 上说明
  form.uploadDir = './uploads';
  form.encoding = 'utf-8';
  form.keepExtensions = true;
  form.maxFieldsSize = 1024 * 1024 * 50; // 50MB

  form.parse(req, function(err, fields, files) {
    console.log('on parse');
    res.writeHead(200, {'content-type': 'text/plain'});
    data = files.fileToUpload;
    res.end(JSON.stringify(data));
  });

  // 我们可以在文件上传完成后移到放置文件的目标目录
  form.on('end', function() {
    fs.renameSync(data.path, './uploads/'+ data.name);
  });
});
