cannot display my variable on browser - node.js

Question

I am working on a socket.io + Node.js project.
When I print an variable using console.log, I get my variable on console.
But when I sent this variable to a client, it seems as [object Object] form on browser.
How can I see my variable on browser?
Thanks

Answer 1

Try console.log(JSON.stringify(myVariable)); and then look at it in your browser and you'll gain more insight as to what's happening exactly.

Answer 2

You may be using the 0.6 serverside syntax of:
socket.send({foo: 'bar'})
Try using the following updated syntax:
socket.json.send({foo: 'bar'})
You can find more information here:

Answer 3

thanks, console.log(JSON.stringify(myVariable)); worked for my case. Variable has shown as
{ coloumn_that_result_lays: "result"}. Of course we can overcome it with javascript-substring but is there a function which gives "result" directly.
// Require HTTP module (to start server) and Socket.IO
var io = require('socket.io'),
http = require('http');
io = require('socket.io');
// Start the server at port 8080
var server = http.createServer(function(req, res){
// Send HTML headers and message
res.writeHead(200,{ 'Content-Type': 'text/html' });
res.end('<h1>Hello Socket Lover!</h1>');
});
server.listen(8080);
// Create a Socket.IO instance, passing it our server
var socket = io.listen(server);
// Add a connect listener
socket.on('connection', function (client){
//mysql
var mysql = require('db-mysql');
new mysql.Database({
hostname: 'localhost',
user: 'root',
password: '123123',
database: 'node'
}).connect(function(error) {
if (error) {
return console.log('CONNECTION error: ' + error);
}
this.query('SELECT data FROM exam where id=2 ').
execute(function(error,result) {
if (error) {
console.log('ERROR: ' + error);
return;
}
client.json.send(JSON.stringify(result));
});
});
// Create periodical which ends a message to the client every 5 seconds
var interval = setInterval(function() {
client.send('This is a message from the server! ' );
},1000);
// Success! Now listen to messages to be received
client.on('message',function(event){
console.log('Received message from client!',event);
});
client.on('disconnect',function(){
clearInterval(interval);
console.log('Server has disconnected');
});
});
