...and also more correct variant

var wifi = require("Wifi");

var page = "<!DOCTYPE html>\r\n<html>\r\n<body>\r\n\r\n";
page += "<form action=\"\" method=\"post\">\r\n First name: ";
page += "<input type=\"text\" value=\"\" name=\"fname\"><br>\r\n  ";
page += "Last name: <input type=\"text\" value=\"\" name=\"lname\"><br>\r\n  ";
page += "<input type=\"submit\" value=\"Submit\">\r\n</form>\r\n\r\n";
page += "<p>Click on the submit button, and the input will be sent to Espruino.";
page += "</p>\r\n\r\n</body>\r\n</html>";

var b;

function onPageRequest(req, res) {
  if (req.method == "GET") {
    res.writeHead(200, { 'Content-Type': 'text/html' });
    res.end(page);
  } else {  
    req.on("close", function () {
      console.log("AVAIL:" + req.available());
      b = req.read();
      console.log("BODY: " + b);
    });

    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end("ok");
  }
}
require("http").createServer(onPageRequest).listen(8080);

var b consist all your data, but data requires parse. (example data: "fname=Pavel&lname=123&xname=rtavel&zname=12673")

for do this i developed little parser:

var str = "fname=Pavel&lname=123&xname=rtavel&zname=12673";

function splitData(data) {
    var dataReady = [];
    var part = true;
    var commVal = "";

    for (var index = 0; index < data.length; index++) {
        if (part) {
            if (data[index] != '=') commVal += data[index];
            else {
                dataReady.push(commVal);
                commVal = "";
                part = false;
            }
        }
        else {
            if (data[index] != '&') commVal += data[index];
            if (data[index] == '&') {
                dataReady.push(commVal);
                commVal = "";
                part = true;
            }
            if (index == data.length - 1) {
                dataReady.push(commVal);
                return dataReady;
            }
        }
    }
}

console.log(splitData(str));

or more simple variant parser:

var str = "fname=Pavel&lname=Dubailo&xname=TEST"

var arr = str.split("&")
var result = {};

arr.forEach(function (pair) {
    var elem = pair.split("=");
    result[elem[0]] = elem[1];
});

console.log(result);
