【中文标题】播放/暂停所有音频链接的通用功能【英文标题】:General function to play/pause all audio links 【发布时间】:2019-06-06 11:43:29 【问题描述】:我有一个带有一堆音频链接的 html。我正在尝试让我的所有音频链接在点击时播放/暂停,我已经尝试了解决方案here。这正是我所追求的,除了我现在坚持修改此函数以应用于我的代码中的所有音频链接(因为我无法为每个链接定义一个函数)。关于如何做到这一点的想法?
例子:
<script type="text/javascript">
function loadAudio(source)
currentSource = source;
audiosource.src = source;
audio.load();
var audio = document.getElementById('audio');
var audioSource = document.getElementById('audioSource');
var currentSource;
document.querySelectorAll('.play-audio').forEach(function(link)
link.addEventListener('click', function()
var linkSource = this.dataset.audio;
if (currentSource === linkSource)
if (audio.paused)
audio.play();
else
audio.pause();
else
loadAudio(linkSource);
audio.play();
);
);
</script>
<audio id="audio">
<source id="audioSource" src=""></source>
Your browser does not support the audio format.
</audio>
<table>
<tr>
<td><a href="#" class="play-audio" data-audio="https://...1">Play 1</a></td>
</tr>
<tr>
<td><a href="#" class="play-audio" data-audio="https://...2">Play 2</a></td>
</tr>
</table>
【问题讨论】:
添加部分代码,看看你是怎么做的以及在哪里触摸代码 【参考方案1】:如果您想一次播放一个音频。您可以通过根据单击的链接更改源来通过相同的音频元素播放它们:
function loadAudio(source)
currentSource = source;
audioSource.src = source;
audio.load();
var audio = document.getElementById('audio');
var audioSource = document.getElementById('audioSource');
var currentSource;
document.querySelectorAll('.play-audio').forEach(function(link)
link.addEventListener('click', function()
var linkSource = this.dataset.audio;
if (currentSource === linkSource)
if (audio.paused)
audio.play();
else
audio.pause();
else
loadAudio(linkSource);
audio.play();
);
);
<audio id="audio">
<source id="audioSource" src=""></source>
Your browser does not support the audio format.
</audio>
<a href="#" class="play-audio" data-audio="sound1.mp3">Click here to hear 1.</a>
<a href="#" class="play-audio" data-audio="sound2.mp3">Click here to hear 2.</a>
<a href="#" class="play-audio" data-audio="sound3.mp3">Click here to hear 3.</a>
【讨论】:
这看起来很不错,但我无法让它工作。当我添加这个时,点击我的链接什么都不会播放(在此之前有声音)。 如果重要,链接是 URL,因此音频不会存储在本地。 @CHRD 抱歉,这是一个愚蠢的问题,但您是否将“sound1.mp3”和其他文件替换为 mp3 文件的链接? 哈哈是的我有XD @CHRD 控制台有错误吗?它对我有用,所以我需要更多信息来帮助你:)【参考方案2】:您可以使用选择器来查找和暂停/播放播放器。
假设您有 4 个<audio>
标签
<div class='audio-container'>
<audio id="audio1" src="/Demo1.mp3"></audio>
<a class='audio-play'>Click here to hear 1.</a>
</div>
<div class='audio-container'>
<audio id="audio2" src="/Demo2.mp3"></audio>
<a class='audio-play'>Click here to hear 2.</a>
</div>
<div class='audio-container'>
<audio id="audio3" src="/Demo3.mp3"></audio>
<a class='audio-play'>Click here to hear 3.</a>
</div>
<div class='audio-container'>
<audio id="audio4" src="/Demo4.mp3"></audio>
<a class='audio-play'>Click here to hear 4.</a>
</div>
使用 JQuery:
$(".audio-container .audio-play").off("click").on("click", function()
// $(this) -> ref to the currently clicked <a/>
//get the [0] element of the FIND query, because a TAG selector returns an array of found elements
var audio = $(this).parent().find("audio")[0];
var hasNotStarted = audio.paused && audio.currentTime == 0 && !audio.ended;
var hasEnded = audio.paused && audio.currentTime > 0 && audio.ended;
var isPaused = audio.paused && audio.currentTime > 0 && !audio.ended;
if(hasNotStarted || hasEnded || isPaused)
audio.play()
else
audio.pause();
);
纯 JS
//in plain JS, you will have to add a click event listener, on each element
var audioElems = document.querySelectorAll(".audio-container .audio-play");
for (var i = 0; i < audioElems.length; i++)
audioElems[i].addEventListener("click", function()
var audio = this.parentNode.children[0]
var hasNotStarted = audio.paused && audio.currentTime == 0 && !audio.ended;
var hasEnded = audio.paused && audio.currentTime > 0 && audio.ended;
var isPaused = audio.paused && audio.currentTime > 0 && !audio.ended;
if(hasNotStarted || hasEnded || isPaused)
audio.play()
else
audio.pause();
);
