This is to start with a very basic page: HTML Form, a button, and a div-box.
.click of the button would POST the Form data through AJAX.
The data is to be stored in MongoDB, and retrieved into the div-box without a page-refresh.
AJAX from index.html:
$(document).ready(function()
{
// handle button clicks
$('#buttonID').click(function() {
// make an ajax call
$.ajax({
dataType: 'jsonp',
jsonpCallback: '_wrapper',
data: $('#formID').serialize(),
type: 'POST',
url: http://localhost:9999/start,
success: handleButtonResponse,
});
});
function handleButtonResponse(data)
{
// parse the json string
var jsonObject = JSON.parse(data);
$('#reponseID').append( jsonObject.message );
}
});
app.js:
var express = require('express'),
app = express();
cons = require('consolidate');
MongoClient = require('mongodb').MongoClient,
Server = require('mongodb').Server;
app.engine('html', cons.swig);
app.set('view engine', 'html');
app.set('views', __dirname + /views);
var mongoclient = new MongoClient(new Server('localhost', 27017,
{ 'native_parser' : true }));
var db = mongoclient.db('database_name');
app.get('/', function (req, res) {
db.collection('collectionName').find({}, function (err, doc) {
res.render('index', doc);
});
response.writeHead(200, {Content-Type:: application/json});
var submittedPost = {};
submittedPost['message'] = 'Proof that Node and Mongo are working..';
response.write( _wrapper(' );
response.write( JSON.stringify(submittedPost) );
response.write( '));
response.end();
});
app.get('*', function (req, res) {
res.send(404.., 404);
});
mongoclient.open(function (err, mongoclient) {
if (err) throw err
app.listen(9999);
console.log(Express server started on port 9999);
});
How/Where does the JSON connect to/from MongoDB?
Also, does Express require a templating engine, such as Consolidate? If so, how/where does that fit in?
