Could someone help me on this topic? I've got this code.

var textArray = [     'song1.ogg',     'song2.ogg' ] audioElement.setAttribute('src', textArray); 

How can I randomly get one of those strings into my audio element?

Would be glad if someone can help....

Answer 1

var textArray = [     'song1.ogg',     'song2.ogg' ]; var randomNumber = Math.floor(Math.random()*textArray.length);  audioElement.setAttribute('src', textArray[randomNumber]); 

Answer 2

var randomIndex = Math.floor(Math.random() * textArray.length);  var randomElement = textArray[randomIndex];
