ReferenceError: audio is not defined

I'm building an audio player in Meteor for a client.

I'm getting an error when I try to create an audio object. I'm using the following code. Any idea why this is happening? Any help would be greatly appreciated.

// Define Audio
song = new Audio('/audio/waitforme.mp3');

// Define Play
play = $('#playicon');

$(function() {
$('#playicon').on("click", function() {
e.preventDefault();
song.play();
})
});

Solution

I think there's a misconception here. You have the right code, but it's running in a different context.

In the case of Meteor, the NodeJS back-end is also running your 'client-side' code. NodeJS doesn't have support for the Audio API that you're using, sadly, but your browser does.

This code serving and running in both the client-side and server-side can get a bit confusing to know the lines between client + server, especially when Meteor tries to blur those lines!

I would look up Meteor's architecture so you can best structure your code to target the 'client-end' vs. 'back-end' environments. A great article is here: https://www.discovermeteor.com/blog/what-goes-where/

Basically, Meteor provides two directories that you can use to specifically target the client or server. You can place files in /client or /server and it will be handled for you.

For something quick or for a file that is used in both contexts, the Meteor docs explains a boolean flag called Meteor.isClient or Meteor.isServer that you can use to mark code to be ran only on the client-side / server-side: http://docs.meteor.com/#/basic/Meteor-isClient
