I was trying to make AJAX post request with JQuery to my Node.JS server in Node.JS and Express, but it doesn't works!
var express = require('express')
var app = express();
app.listen(8888);
app.configure(function(){
app.use(express.bodyParser());
app.set('views',__dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.static(__dirname + '/public'));
app.use(express.cookieParser());
app.use(app.router);
});
app.get('/', function (req, res){
res.render('ajax.ejs');
});
app.post('/ajax', express.bodyParser(), function (req, res){
console.log(req);
console.log('req received');
res.redirect('/');
});
And this is the ajax.ejs:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script type="text/javascript">
$('#enter').click(function(){
$.ajax({
url: '/ajax',
type: 'POST',
cache: false,
data: { field1: 1, field2: 2 },
success: function(data){
alert('Success!')
}
, error: function(jqXHR, textStatus, err){
alert('text status '+textStatus+', err '+err)
}
})
});
</script>
</head>
<body>
<form>
<input type="button" id="enter" value="Enter">
</form>
</body>
</html>
When the ajax.ejsis loaded, there isn't any output in the console, so, the post request didn't work. What can I do?
Thanks advance!

I found your problem. You need to move your script from your head to your body (after the form tag):
...
</form>
<script type="text/javascript">
$('#enter').click(function(){
...
</script>
</body>
The below code works as per the new releases.
server.js
var express = require('express')
var app = express();
var bodyparser = require('body-parser');
var urlencodedparser = bodyparser.urlencoded({extended:false})
app.set('views',__dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.static(__dirname + '/public'));
app.use(express.cookieParser());
app.get('/', function (req, res){
res.render('ajax.ejs');
});
app.post('/ajax', urlencodedparser, function (req, res){
console.log(req);
console.log('req received');
res.redirect('/');
});
app.listen(8888);
ajax.ejs

}
})
