Asp.net 2.0 Web Pages_play file mp3, mp4

Question

I want to play mp3 and mp4 files in Pages using html5, JavaScript and jQuery. If files are in a project that play files it works but if the files are in another folder on my computer( E, D or Download...) they don't run.
Error:

Error :searchms.aspx:1491 Uncaught (in promise) DOMException: The element has no supported sources.

(play.click(function (e) { e.preventDefault(); song.play();  // this error

Answer 1

Since Chrome 50, a play() call on audio (or video) element returns Promise instance (further details can be found in this reference). You should add detection for successful play and the Promise instance is fulfilled like this example:

HTML

<audio id="song" src="../path/to/audio/file.mp3" />
<button id="play">Play</button>

JS

var play = $('#play'); // example
play.click(function (e) { 
    e.preventDefault(); 
    var playback = document.querySelector('#song').play();
    if (playback !== undefined) {
        playback.then(function() {
            // do something
        }).catch(function(error) {
            // do something else
        });
    }
});

Another example can be found in HTMLMediaElement.play() Returns a Promise Sample.

If it turns to be CORS issue, try to set crossorigin attribute as anonymous one, then ensure that response header returned from server contains Access-Control-Allow-Origin: *:

var song = document.getElementById('song');
song.setAttribute('crossorigin', 'anonymous');

// or this:
song.crossOrigin = 'anonymous';
