How can I use howler js and update the progress bar as the audio plays?
I assume I use either pos or seek however I can't seem to get it working.
Can I create a on event listener to change every time the position changes?
Progress bar HTML:
<progress id="progress_bar" value="0.0" max="1.0" style="-webkit-appearance: none; appearance: none; height: 48px; float: left;"></progress>
Howler js:
on ('update_progress', function() {
document.getElementById('progress_bar').value = audio.pos();
}),
and then how can I update the position of the audio if the progress bar is pressed. I think I might actually be better served using an input range in that case.
There is currently no progress event in howler.js, though it may get added at a later date. However, you can get the current position by calling audio.seek() at any time (on 2.0) or audio.pos() on 1.0. You could then either call this in requestAnimationFrame (this is what the 2.0 demos use) or setInterval to update your progress bar.
