HTML5/jQuery audio shuffle onClick

问题

I have a simple HTML5 audio playlist and I would like the user to click a "shuffle" button and shuffle the audio but I don't know the best way to go about this. I'm using audio.js for HTML5 audio.

As you can see in the fiddle, audio.js grabs the <a> tag inside the <li> to play an audio file in the player at the top. The shuffle button would need to pick a random <li a> on click.

Any help would be greatly appreciated! Thank you!

Here is the logic for shuffle button. You'll have to write in the code to the get the track to play but it shouldn't be that difficult. I added a class to the ul called "tracks".

 $(".shufflebutton").click(function() {
        var trackCount = $(".tracks li").length;
        console.log('trackCount:' + trackCount);
         /* Pick random number between 1 and trackCount */
        var randomNum = Math.ceil(Math.random()*trackCount); 
        console.log("randomNum:" + randomNum);     
      });
