Script Clip: HTML5 Audio Player with jQuery Controls

HTML5 and jQuery provide mind-blowing functionality. Projects that would have taken hours of development and hundreds of lines of code a few years ago can now be completed in about the time it'll take you to read this paragraph. If you wanted to add your own audio player on a web page in the past, what would it have involved? Complicated elements? Flash (*shudders*)? It was so complicated that most developers just linked to the audio file, and the user just downloaded the file to play it locally. With HTML5, an embedded, cross-browser audio player can be added to a page with five lines of code, and if you want to get really fancy, you can easily use jQuery to add some custom controls.

If you've read any of my previous blogs, you know that I love when I find little code snippets that make life as a web developer easier. My go-to tools in that pursuit are HTML5 and jQuery, so when I came across this audio player, I knew I had to share. There are some great jQuery plugins to play music files on a web page, but they can be major overkill for a simple application if you have to include comprehensive controls and themes. Sometimes you just want something simple without all of that overhead:

Oooh... Ahhh...

That song — Pop Bounce by SoftLayer's very own Chris Interrante — is written in five simple lines of HTML5 code:

<audio style="width:550px; margin: 0 auto; display:block;" controls>
  <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.ogg" type="audio/ogg">
  <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

If IE 9+, Chrome 6+, Firefox 3.6+, Safari 5+ and Opera 10+ would all agree on supported file formats for the <audio> tag, the code snippet would be even smaller. I completely geek out over it every time I look at it and remember the days of yore. As you can see, the HTML5 application has some simple default controls: Play, Pause, Scan to Time, etc. As a developers, I couldn't help but look for a to spice it up a little ... What if we want to fire an event when the user plays, pauses, stops or takes any other action with the audio file? jQuery!

Make sure your jQuery include is in the <head> of your page:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>

Now let's use jQuery to script separate "Play" and "Pause" links ... And let's have those links fire off an alert when they are pressed:

$(document).ready(function(){
  $("#play-button").click(function(){
   $("#audioplayer")[0].play();
   alert('You have played the audio file!');
  })    
 
  $("#pause-button").click(function(){
   $("#audioplayer")[0].pause();
   alert('You have paused the audio file!');
  })    
})

With that script in the <head> as well, the HTML on our page will look like this:

<div class=:"audioplayer">
  <audio id="audioplayer" name="audioplayer" controls loop>
    <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.ogg" type="audio/ogg">
    <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.mp3" type="audio/mpeg">
  Your browser does not support the audio element.
  </audio>
 
  <a id="play-button" href="#">Play!</a>
  <a id="pause-button" href="#">Pause!</a>
</div>

Want proof that it works that simply? Boom.

You can theme it any way you like; you can add icons instead of the text ... The world is your oyster. The bonus is that you're using one of the lightest media players on the Internet! If you decide to get brave (or just more awesome), you can explore additional features. You're using jQuery, so your possibilities are nearly limitless. If you want to implement a "Stop" feature (which returns the audio back to the beginning when "Stop" is pressed), you can get creative:

$("#stop-button").click(function(){
    $("#audioplayer")[0].currentTime = 0; // return the audio file back to the beginning
}

If you want to include some volume controls, those can be added in a snap as well:

$("#volumeUp").click(function(){
    $("#audioplayer")[0].volume +=0.1;
}
 
$("#volumeDown").click(function(){
    $("#audioplayer")[0].volume -=0.1;
}

Try it out and let me know what you think. Your homework is to come up with some unique audio player functionality and share it here!
