How do I get Html5 audio to play sound on click? (ogg for browsers like Firefox and mp3 for browsers like chrome)

So far onclick I can change to a single filetype but I can't get it to have a backup option like you do on a normal html5 audio declaration i.e.

<audio controls>
  <source src="horse.ogg" type="audio/ogg">
  <source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ".dtd">
<html xmlns="">

<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>How do i call the javascript function and get it to play .ogg if can't play .mp3?</title>
</head>
<body>
    <audio id="Mp3Me" autoplay autobuffer controls>
  <source src="Piano.mp3">
</audio>

<a href="javascript:GuitarTrack()">Guitar</a>

<script type="text/javascript">
function GuitarTrack(){
var Mp3Me= document.getElementById('Mp3Me');
Mp3Me.src = "Guitar.mp3";
Mp3Me.src = "Guitar.ogg";
}
</script>

</body>

</html>

Reset to default 3

Since you are creating only one <source> element, you have to either create another <source> element in HTML or create one using JavaScript.

  1. Creating second element using HTML. http://jsfiddle/PVqvC/

    <audio id="Mp3Me" autoplay autobuffer controls>
<source src="Piano.mp3">
<source src="Piano.ogg">
</audio>
<a href="javascript:GuitarTrack();">Guitar</a>

<script type="text/javascript">
function GuitarTrack(){
    var Mp3Me= document.getElementById('Mp3Me');
    Mp3Me.children[0].src = "Guitar.mp3";
    Mp3Me.children[1].src = "Guitar.ogg";
    Mp3Me.load();
}
</script>

  2. Creating second element using JS. http://jsfiddle/MBvsC/1/

    <audio id="Mp3Me" autoplay autobuffer controls>
<source src="Piano.mp3">
</audio>
<a href="javascript:GuitarTrack();">Guitar</a>

<script type="text/javascript">
function GuitarTrack(){
    var Mp3Me= document.getElementById('Mp3Me').getElementsByTagName('source');

    if(Mp3Me.length > 1) { //there are 2 elements
        Mp3Me[0].src = "Guitar.mp3";
        Mp3Me[1].src = "Guitar.ogg";
    }
    if(Mp3Me.length == 1) { //only one element, so we need to create the second one
        Mp3Me[0].src = "Guitar.mp3"; //changes existing element

        var node = document.getElementById('Mp3Me');
        var newelem = document.createElement('source');
        newelem.setAttribute('src', 'Guitar.ogg');
        node.appendChild(newelem); //creating new element with appropriate src                         
    }
    Mp3Me.load();
}
</script>

As you can see, the first method is a lot shorter and cleaner, so if you can use it - use it. If you have any further questions - feel free to ask.
