I made this piece of code for turning sound on/off in a game I'm making. It works great with Google Chrome and IE. Proud as I was I gave the code to my friend who tried it on Firefox..
But he made me sad by saying it didn't work on Firefox...
I don't know why it doesn't work, can somebody tell me what's wrong or maybe what I have to change?
P.S.: "geluidknop" is Dutch for "soundbutton".
var audio = new Audio('Beep.mp3');
function playAudio() {
audio.play();
}
function pauseAudio() {
audio.pause();
audio.currentTime = 0;
}
window.addEventListener('keydown', playAudio);
audio.play();
function CanvasApp() {
'use strict'
var canvas = document.getElementById("canvas"),
style = window.getComputedStyle(canvas),
context = canvas.getContext("2d"),
source1 = "geluidaan.png",
source2 = "geluiduit.png",
click = false,
geluidknop = {x: 0, y: 0, width: 1024, height: 768};
geluidknop.aspect = geluidknop.height / geluidknop.width;
geluidknop.width = 500;
geluidknop.height = geluidknop.width * geluidknop.aspect;
canvas.width = parseInt(style.width, 10);
canvas.height = parseInt(style.height, 10);
var img = new Image();
img.onload = function () {
context.drawImage (img, geluidknop.x, geluidknop.y, geluidknop.width, geluidknop.height);
};
img.src = source1;
function changeImage() {
if (click) {
img.src = source2;
} else {
img.src = source1;
}
}
function MouseClick() {
var rect = canvas.getBoundingClientRect(),
x = event.clientX - rect.left,
y = event.clientY - rect.top;
if (x >= geluidknop.x && x <= geluidknop.x + geluidknop.width) {
if (y >= geluidknop.y && y <= geluidknop.y + geluidknop.height) {
if (click) {
click = false;
playAudio();
changeImage();
}else {
click = true;
pauseAudio();
changeImage();
}
}
}
context.save();
context.setTransform(1, 0, 0, 1, 0, 0);
context.clearRect(0, 0, canvas.width, canvas.height);
context.restore();
}
canvas.addEventListener('click', MouseClick);
function restartAudio() {
audio.currentTime = 0;
audio.play();
}
audio.addEventListener('ended', restartAudio);
}
function WindowLoaded() {
'use strict';
CanvasApp();
}
window.addEventListener("load", WindowLoaded);

I think you forgot to pass event
to your event handler function. Chrome will fill this in, but Firefox will not.
It should be:
function MouseClick(event) {}

This issue might not be your code, but more likley .mp3 support in firefox. Dependant on the version of firefox he was using a .mp3 file might not be supported
check out the mozilla docs on audio support
