HTML5 introduces the <audio> element which offers a way to play audio natively
in the browser. However the native controls are a little lacking in style.
Thankfully HTML5 also brings a full api to interact with which allows us to skin
an Audio object however we want.
The primary goal of this project is to create a high quality HTML5 audio boombox that can be easily skinned and extended.
First things first—make sure you’re running a modern browser. My favorite is Chrome but Safari, Opera, Firefox, or even IE9 will also do.
Let me repeat that—this app works in ALL major modern browsers.
Next grab the latest copy of jQuery and boombox.js and include a link to both of
them in your HTML <head> section.
<head>
<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
<script src="js/boombox.js" type="text/javascript"></script>
</head>
In theory you could have as many boomboxes on a page as you wish. For each one you'll need to provide the following markup. Make sure that you wrap each group of buttons in a div with a unique id. You'll be using that unique id in the next step.
<div id="boombox">
<div><span class="boomboxCounter">1</span> <span class="boomboxTrackName"></span></div>
<button class="boomboxPlayBtn">Play</button>
<button class="boomboxPauseBtn">Pause</button>
<button class="boomboxPreviousBtn">Previous</button>
<button class="boomboxNextBtn">Next</button>
<button class="boomboxVolumeDownBtn">Volume Down</button>
<button class="boomboxVolumeUpBtn">Volume Up</button>
<button class="boomboxMuteBtn">Mute</button>
</div>
To create a new boombox simply call
new Boombox(//arguments);
The Boombox constructor takes an object literal of tracks and configuration values.
<script>
new Boombox(
tracks : {
'Blasting Laser Fire' : './music/BlastingLaserFire',
'Ultra Drop' : './music/UltraDrop'
},
configs : {
container : '#boombox',
autoplay : false
}
);
</script>
Notice the object literal being passed into the Boombox constructor has two properties which are themselves objects—tracks and configs.
The titles and paths for the audio tracks go in the tracks object. The audiotrack paths don’t have a file extension. That’s
because boombox detects what codec the browser supports and serves up the
correct file. As a developer you need to encode your audiofiles once as .mp3 and
once as .ogg and put the path to those files in the object literal that is
passed into the boombox function.
In the configs object you put the id of the container div for this boombox as well as a boolean value which triggers autoplay.
To get Firefox to recognize the .ogg file type correctly you’ll need to add this one line to the .htaccess file on the server that is serving up the audiofiles.
AddType audio/ogg .ogg
