小编Pol*_*nce的帖子

I'm trying to play audio files (I've tried many). All of them are mp3s. I've tested the following on both MAMP localhost and also by just running it in the browser.

I use the following javascript:

var testSound = new Audio();
testSound.src = "a.mp3"
setTimeout(testSound.play.bind(testSound),100)

This returns the error:

Uncaught (in promise)

Trying to catch it:

var testSound = new Audio();
testSound.src = "a.mp3"
setTimeout(playSound,100)
function playSound () {
    testSound.play().then(response => {

    }).catch(e => {
        console.log(e);
    })
}

returns nothing …
