Why is my emit not getting called?

- by cRaZiRiCaN

The client and server connect just fine. For some reason the emit on my client is not firing correctly. I am trying to get the testEmit and testEmit2 working. This is my server: express = require 'express' mongo = require 'mongodb' app = express() server = (require 'http').createServer(app) io = (require 'socket.io').listen(server) server.listen(8080) app.use(express.static(__dirname + '/public')) # db = new mongo.Db("documentsdb", new mongo.Server("localhost", 27017, auto_reconnect: true), {safe:true}) io.sockets.on 'connection', (socket) -> console.log 'Socket.io is connected!' #This returns an array of documents sorted via date by decreasing order. (Most recent documents first.) socket.on 'loadRecentDocuments', -> console.log 'Loading most recent documents.' db.collection 'documents', (err, collection) -> collection.find().sort(dateAdded: -1).toArray (err, documents) -> #This emit is recieved at index.html where a javascript function sendDocuments manages the documents. socket.emit 'sendDocuments', documents return #The index.html provides the code data from the search box via a javascript. io.sockets.on 'findDocuments', (code) -> #Returns an array of documents with the corresponding class code. documentCodeToSearch = code console.log 'Retreaving documents with code: ' + documentCodeToSearch db.collection 'documents', (err, collection) -> collection.find(code:documentCodeToSearch).toArray (err, documents) -> socket.emit 'sendDocuments', documents return #Uploads a document to the server. documentData is sent via javascript from submit.html io.sockets.on 'addDocument', (documentData) -> console.log 'Adding document: ' + documentData db.collection 'documents', (err, collection) -> collection.insert documentData, safe: true return #Test socket.io io.sockets.on 'testEmit', -> console.log('Emit recieved.') socket.emit 'testEmit2', 'caca' return app.listen 1337 console.log "Listening on port 1337..." This is my client: <!doctype HTML> <html> <head> <title>ProjectShare</title> <script src="http://localhost:8080/socket.io/socket.io.js"></script> <script src = "http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <script> //Make sure DOM is ready before mucking around. $(document).ready(function() { console.log('jQuery entered!'); var socket = io.connect('http://localhost:8080'); socket.emit('testEmit'); socket.on('testEmit2', function(data) { console.log('Emit recieved at browser.'); console.log(data); }); console.log('jQuery exit.'); }); </script> </head> <body> <ol> <li><a href="index.html">ProjectShare</a></li> <li><a href="guidelines.html">Guidelines</a></li> <li><a href="upload.html">Upload</a></li> <li> <form> <input type = "search" placeholder = "enter class code"/> <input type = "submit" value = "Go"/> </form> </li> </ol> <ol id = "documentList"> </ol> </body> </html>
