我想制作播放mp3音频的4个播放按钮。播放功能每4个按钮工作一次,但不幸的是暂停不适用于其中任何一个。也许暂停条件错了?
bundle exec rspec --tag ~http_request
<div class="audio-button">
<audio src="media/test.mp3"></audio>
</div>
<div class="audio-button">
<audio src="media/test2.mp3"></audio>
</div>
<div class="audio-button">
<audio src="media/test3.mp3"></audio>
</div>
<div class="audio-button">
<audio src="media/test4.mp3"></audio>
</div>

您需要在孩提时直接从按钮中获取音频元素并与之交互。您不需要使用构造函数克隆Audio
对象。
$(document).ready(function() {
var playing = false;
// Add file names.
$('.audio-button').each(function() {
var $button = $(this);
var $audio = $button.find('audio');
$($('<span>').text($audio.attr('src'))).insertBefore($audio);
});
// Add click listener.
$('.audio-button').click(function() {
var $button = $(this);
var audio = $button.find('audio')[0]; // <-- Interact with this!
// Toggle play/pause
if (playing !== true) {
audio.play();
} else {
audio.pause();
}
// Flip state
$button.toggleClass('playing');
playing = !playing
});
});
.fa.audio-button {
position: relative;
display: block;
width: 12em;
height: 2.25em;
margin-bottom: 0.125em;
text-align: left;
}
.fa.audio-button:after {
position: absolute;
right: 0.8em;
content: "\f04b";
}
.fa.audio-button.playing:after {
content: "\f04c";
}

你想在点击一个时停止其他三个吗?
如果是这样,你可以尝试:
$(document).ready(function () {
$('.audio-button').click(function (e) {
var button = $(e.target).closest('.audio-button');
var audio = button.find('audio');
var audioDom = audio.get(0);
$('audio[data-is-playing]').not(audio).each(function (i, currentAudioDom) {
var currentButton = $(currentAudioDom).closest('.audio-button');
currentButton.removeClass('playing');
currentButton.removeAttr('data-is-playing');
currentAudioDom.$audio.pause();
});
button.addClass('playing');
audio.attr('data-is-playing', '');
audioDom.$audio = audioDom.$audio || new Audio(audio.attr('src'));
audioDom.$audio.play();
});
});
修正:
实际上我不确定音频元素本身是否是音频对象,如果是这样,你可以直接在audioDom / currentAudioDom元素上调用播放/暂停,而忘记$ audio的事情... < / p>
