How can I add multiple sources to an HTML5 audio tag, programmatically?
Why add multiple files with JavaScript when you can just detect the types supported? I would suggest instead detecting the best type then just setting the src.
var source= document.createElement('source');if (audio.canPlayType('audio/mpeg;')) { source.type= 'audio/mpeg'; source.src= 'audio/song.mp3';} else { source.type= 'audio/ogg'; source.src= 'audio/song.ogg';}audio.appendChild(source);Add as many checks as you have file types.
You can use the same DOM methods as with any other element:
var source= document.createElement('source');source.type= 'audio/ogg';source.src= 'audio/song.ogg';audio.appendChild(source);source= document.createElement('source');source.type= 'audio/mpeg';source.src= 'audio/song.mp3';audio.appendChild(source);
