我想在使用ScrollMagic进入/离开场景时播放并停止音频。js。它在Chrome中抛出了“未捕获的（promise中的）DomeException”。有什么问题？
我有像下面这样的html结构。我想在使用ScrollM进入每张幻灯片时自动播放音频agic.js.
<div class="slide" id="slide-0">
<div class="trigger"></div>
<audio class="audio" src="audio/audio01.mp3" preload="auto"></audio>
</div>
<div class="slide" id="slide-1">
<div class="trigger"></div>
<audio class="audio" src="audio/audio02.mp3" preload="auto"></audio>
</div>
<div class="slide" id="slide-3">
<div class="trigger"></div>
<audio class="audio" src="audio/audio03.mp3" preload="auto"></audio>
</div>
var controller = new ScrollMagic.Controller();
var scenes = [];
$('.slide').each(function(index) {
var trigger = '#slide-' + index + ' .trigger';
var audio = '#slide-' + index + ' audio';
scenes[index] = new ScrollMagic.Scene({
triggerElement: trigger,
triggerHook: 'onCenter',
duration: '50%' })
.addIndicators({name: trigger, colorEnd: "#00FFFF"})
.on('enter', function() {
console.log('Enter' + trigger);
$(audio).get(0).play();})
.on('leave', function() {
console.log('Leave' + trigger); })
.addTo(controller);
});
当触发器激活时，控制台在Chrome中显示“未捕获（promise中）DOMExc0019”。我试过边缘，很好。我怎样才能解决这个问题？
您的想法是正确的，因为每个div理论上都有相同的受尊重音频元素索引。只需使用div循环的索引来播放音频元素即可。
例子：
let scenes = [];
// init controller
var controller = new ScrollMagic.Controller();
$('.slide').each(function(index) {
var trigger = '#slide-' + index + ' .trigger';
var audio = '#slide-' + index + ' audio';
scenes[index] = new ScrollMagic.Scene({
triggerElement: trigger,
triggerHook: 'onCenter',
duration: '50%'
})
.addIndicators({
name: trigger,
colorEnd: "#00FFFF"
})
.on('enter', function() {
let audio = $('audio')
console.log('Playing audio at index', index)
audio[index].play();
})
.on('leave', function() {
console.log('Leave' + trigger);
})
.addTo(controller);
