socket.io - ReferenceError: io is not defined

Question

I am writing an application for Android 2.3.5 (that will also be compatible with iOS). I wish to transfer data from the app\'s HTML/Javascript to a Python program on a serve

Answer 1

For me after debugging through all of the very helpful suggestions, it turned out to be simply that my node server had stopped. I had been running it manually in a terminal window during dev.

Make sure your node [yourservercode].js is running on the specified port! :-]

Answer 2

I managed to blunder through this, and squandered about an hour, on something that turned out to be a very basic error.

When an function is not defined? Such as " Uncaught ReferenceError: io is not defined ". Does that not mean that the function is getting "used" before it is "created"?

In the part of my HTML file, that "calls" the javaScript files, it looked like this :

<script src='./js/playerChatter.js'></script> <!-- this one calls io -->
<script src="http://localhost:2019/socket.io/socket.io.js"></script><!-- This Creates io -->

and i changed it to this

<script src="http://localhost:2019/socket.io/socket.io.js"></script> <!-- This Creates  io -->
<script src='./js/playerChatter.js'></script> <!-- this on calls io -->

So now the item "io", whether it is an object or function... Is actually getting created before it is getting used :D

Have FUN!
