Audio loop setting?

JavaScript
1

Where in this JS does it show whether the audio should repeat or not? How can I add it to this?

import lottieWeb from 'https://cdn.skypack.dev/lottie-web';

        super();

        shadow.appendChild(templateContent.cloneNode(true));
    }

    connectedCallback() {
        everything(this);
    }
}

I think I found something to add to the line

const audio = shadow...etc.

I added this below it

audio.loop = false;

3

It’s still looping in the iPad. From desktop it works fine. :thinking:

4

Does the variable count in the last few lines of the code you posted have anything to do with it?

5

I’m not sure. Where is that?

6

Oh ok I found it. I don’t think so, because I removed that line after seeing that it didn’t work out.

Does your HTML <audio> tag include the loop attribute?

8

No, this is the HTML that I have

<div id="audio-player-container"><audio src="" preload="metadata" loop></audio><button id="play-icon" title="Play/Pause"></button><span id="song" class="title">Evenstar</span><span id="current-time" class="time">0:00</span><input type="range" id="seek-slider" max="100" value="0"><span id="duration" class="time">0:00</span><output id="volume-output">100</output><input type="range" id="volume-slider" max="100" value="100"><button id="mute-icon" title="volume"></button></div>

  <audio-player data-src="https://docs.google.com/uc?export=download&id=1W3YcvV7--lsBko9iOngVkBHu-4sXMDG6"></audio-player>

There is a tag in it also, but I didn’t include it here, to show you what the HTML part of the audio player is… but, I could if you need to see that.

Well maybe this

preload="metadata" loop

Is what you’re mentioning? I tried making it as loop="false", and this helped on desktop, but not iPad…

Also, my mute icon to the player is on the wrong side in the iPad. I don’t know how that’s happened, as I didn’t change anything…

11

Yes, all you need to do is just delete loop. Don’t put ="false". What then happens on your iPad?

Ok let me try that. Well, then it will stop looping on desktop as well… or would it?

13

iPad - no loop after

Desktop - no loop after

Yes, thanks :slight_smile: . So then how would I make it so it resets to 0:00 after the song ends?

16

I suggest adding an event listener for the ended event and use that to set the text to 0.00.

Like this


addEventListener("ended", (event) => {});

onended = (event) => {0};
18

Try this:

audio.addEventListener("ended", () => {currentTimeContainer.textContent = "0.00";});

Where in the script does it go?

I could put it before this

audio.addEventListener('progress', displayBufferedAmount);
      seekSlider.addEventListener('input', (e) => {
        showRangeProgress(e.target);
        currentTimeContainer.textContent = calculateTime(seekSlider.value);
        if (!audio.paused) {
          cancelAnimationFrame(raf);
        }
      });
