I have been trying to add an If/Else statement to my Socket.io client for a personal project I've been working on. The end goal is to create a Bitcoin ticker with 2 values (oldPrice and newPrice) sent from the server. I would like to be able to change the styling and bg color depending on the values.

This is what I have to far:

var socket = io.connect('http://localhost:1000');

socket.on('newPrice', function(data){
   var newPrice = data.value  
});

socket.on('oldPrice', function(data){
   var oldPrice = data.value    
});

Open in new window


I would like to add this:

if (newPrice < oldPrice) {

            }else if (newPrice > oldPrice) {

            }

Open in new window


Thanks!

Hi,
I think you have to generate the variables "globally" like
var socket = io.connect('http://localhost:1000');
var newPrice = 0, oldPrice = 0;

socket.on('newPrice', function(data){
   newPrice = data.value  
});

socket.on('oldPrice', function(data){
   oldPrice = data.value    
});

Open in new window


Your compare should then be like
if (newPrice < oldPrice) {

            }else {

            }

Open in new window
