Custom progress bar for <audio> and <progress> HTML5 elements

Question

I am mind boggled at working out how to create a custom seekbar for an audio player using the tag and simple Javascript.

Current Code:

    <script>   function play() {    document.getElementById('player').play();   }    function pause() {    document.getElementById('player').pause();   } </script>   <audio src="sample.mp3" id="player"></audio>   <button onClick="javascript:play()" >Play</button> <button onClick="javascript:pause()" >Pause</button> <progress id="seekbar"></progress> 

Would it be possible to link the progress bar so that when i play a song the progress is shown?

Answer 1

Yes, it is possible using the timeupdate event of the audio tag. You receive this event every time the position of the playback is updated. Then, you can update your progress bar using the currentTime and duration properties of the audio element.

You can see a working example in this fiddle

Answer 2

If you want smooth progress bar,try somethink like that

HTML:

<div class="hp_slide">      <div class="hp_range"></div> </div> 

CSS:

.hp_slide{     width:100%;     background:white;     height:25px; } .hp_range{     width:0;     background:black;     height:25px; } 

JS:

var player = document.getElementById('player');     player.addEventListener("timeupdate", function() {     var currentTime = player.currentTime;     var duration = player.duration;     $('.hp_range').stop(true,true).animate({'width':(currentTime +.25)/duration*100+'%'},250,'linear'); }); 

Pretty rough,but works
