javascript - Node+Express Post Error -

i trying post fields form lista[0].usuario seems empty in jade page.

i using: node version v0.12.3000 express 3.20.3

--my code--

---app.js---

var express = require('express'); var routes = require('./routes'); var http = require('http'); var path = require('path');  var app = express();  var v_login = require('./routes/login');  // environments app.set('port', process.env.port || 3000); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'jade'); app.use(express.logger('dev')); app.use(express.json()); app.use(express.urlencoded()); app.use(app.router); app.use(express.static(path.join(__dirname, 'public')));  // development if ('development' == app.get('env')) {     app.use(express.errorhandler()); }  app.get('/login', v_login.login); app.get('/login', v_login.get_enviar); app.post('/login', v_login.post_enviar);  http.createserver(app).listen(app.get('port'), function(){     console.log('express server listening on port ' + app.get('port')); }); 

---login.js---

var lista = new array();  function login(req, res){     res.render('login'); };  exports.login = login;  exports.get_enviar = function(req, res){     login(req, res); }  exports.post_enviar = function(req, res){ var usuario = req.body.usuario; var password = req.body.password; console.log(usuario); console.log(password);  lista.push({     usuario: usuario,     password: password }) res.render('login', {lista: lista}); console.log(lista[0].usuario); console.log(lista[0].password);   } 

---login.jade---

doctype html html(lang='en') head body #container form#frm(method="post", name="frm", action="login", enctype="application/x-www-form-urlencoded") h1 login h2 usuario input#usuario(name='usuario', type='text', value='') br h2 password input#password(type='password', name='password', value='') br br input(type='submit', value='conectar') br br if lista     h1 #{lista[0].usuario}  #footer 

you calling login function:

exports.post_enviar = function(req, res){     var usuario = req.body.usuario;     var password = req.body.password;     lista.push({         usuario: usuario,         password: password     })     login(req, res); // here } 

but if see, don't have declaration of function in login.js file.

you have login exposed on exports object:

exports.login = function(req, res){     res.render('login'); }; 

like above post says, can declare login function separate function:

function login(req, res){     res.render('login'); } 

and update export object to:

exports.login = login; 

so that:

 exports.post_enviar = function(req, res){     var usuario = req.body.usuario;     var password = req.body.password;     lista.push({         usuario: usuario,         password: password     })     login(req, res); // here } 

it work ok.

updates:

• you using express 3.x

regarding problem need add emphasized line app.js file:

     // environments     ..     app.use(express.logger('dev'));     app.use(express.json());     app.use(express.urlencoded());     .. 

then able values usuario , password in req.body object.

another update:

you need check if lista variable contains username , password. change emphasized code index.jade:

       ..       input(type='submit', value='conectar')       br       br      if lista       h1 #{lista[0].usuario}      #footer     .. 

once finish processing usuario , password values, need re-render index html passing list array:

then in exports.post_enviar method change emphasized code @ end of method:

       ..       lista.push({           usuario: usuario,           password: password       })           console.log(lista[0].usuario);       console.log(lista[0].password);          res.render('index', {lista: lista});     }
