Play one HTML audio element at a time

问题

I have many audio elements on a single page and I want to play just one element at a time. That is if one audio element is playing and I click on play on another element, the previous audio element should pause.

I found a jQuery code from another question to do this but that uses an image as play/pause controls. I'm using the inbuilt controls='controls' attribute for the audio element instead. Is it possible to use jQuery to control the play/pause feature for the audio element in my case?

Here is my HTML code

<div>
    <p class="song"><h3><strong>#1 Intro - The Oath</strong></h3><p>
    <audio class="playback" src=http://geo-samples.beatport.com/lofi/5005876.LOFI.mp3 controls='controls' preload="none">
        <I>Your browser does not support the audio element.</I>
    </audio>
</div>

<div>
    <p class="song"><h3><strong>#2 A State Of Trance Year Mix 2013</strong></h3></p>
    <audio class="playback" src=http://geo-samples.beatport.com/lofi/5005933.LOFI.mp3 controls='controls' preload="none">
        <I>Your browser does not support the audio element.</I>
     </audio>
</div>

Here is the jQuery code

$(document).ready(function() {
    var curPlaying;

    $(function() {
        $(".playback").click(function(e) {
            e.preventDefault();
            var song = $(this).next('audio')[0];
            if(song.paused){
                song.play();
                if(curPlaying) $("audio", "#"+curPlaying)[0].pause();
            } else { song.pause(); }
            curPlaying = $(this).parent()[0].id;
        });
    });
});

The jQuery code doesn't seem to be working for me.

回答1:

$(function(){
    $("audio").on("play", function() {
        $("audio").not(this).each(function(index, audio) {
            audio.pause();
        });
    });
});

See sample at JSFiddle

Vanilla JS solution

Here's a solution that doesn't require jQuery.

function onlyPlayOneIn(container) {
  container.addEventListener("play", function(event) {
  audio_elements = container.getElementsByTagName("audio")
    for(i=0; i < audio_elements.length; i++) {
      audio_element = audio_elements[i];
      if (audio_element !== event.target) {
        audio_element.pause();
      }
    }
  }, true);
}

document.addEventListener("DOMContentLoaded", function() {
  onlyPlayOneIn(document.body);
});

Some things to note:

Because this listens for events on a parent element, not on the audio elements themselves, they can be added or removed after the page is loaded and it will still work.
It watches for the play event in the capture phase because play events don't bubble.
More media events are described here on MDN.
Listening for "DOMContentLoaded" should work for most browers.

Assuming that your syntax for stopping and pausing tracks is correct (I don't know anything about the audio element), you should be able to do something like this:

$(".playback").click(function(e) {

  // pause all other tracks
  $('.audio').each(function () {
    var song = this;
    if (!song.paused) { song.pause(); }
  });

  // play the audio associated with this element
  this.play();

});

Little Modification to LostInComputer's Answer

In Your HTML Write:

<audio controls onplay="pauseOthers(this);" >
                    <source src="SourcePath">

                </audio>

In Js Write:

function pauseOthers(ele) {
                $("audio").not(ele).each(function (index, audio) {
                    audio.pause();
                });
            }
