Question

I am wanting to know how to check if a HTML5 audio element is loaded.

Answer 1

To find out when the audio is ready to start playing, add listeners for the oncanplay or oncanplaythrough events. To find out when the audio has loaded at all, listen to the onloadeddata event:

<audio oncanplay="myOnCanPlayFunction()"
       oncanplaythrough="myOnCanPlayThroughFunction()"
       onloadeddata="myOnLoadedData()"
       src="myaudio.ogg"
       controls>
    <a href="myaudio.ogg">Download</a>
</audio>

<script>
function myOnCanPlayFunction() { console.log('Can play'); }
function myOnCanPlayThroughFunction() { console.log('Can play through'); }
function myOnLoadedData() { console.log('Loaded data'); }
</script>
