play（）失败，因为用户没有首先与文档进行交互-使用Vimeo API的点击事件

Question

我假设一个onclick事件被视为与文档互动，所以不确定为什么会引发自动播放错误

未捕获（按承诺）NotAllowedError：play（）失败，因为用户未首先与文档进行交互。

const playbtn = document.getElementById('playbtn');
const player = document.getElementById('video-player');
const vimeoPlayer = new Vimeo.Player(player);
playbtn.onclick = function() {
  playbtn.style.display = "none";
  vimeoPlayer.play();
}
vimeoPlayer.on('pause', function() {
  playbtn.style.display = "block";
});
vimeoPlayer.on('play', function() {
  playbtn.style.display = "none";
});

i {
  position: absolute;
  color: white;
}
.fa-play-circle {
        display: block;
        position: absolute;
        left: 50%;
        top: 50%;
        font-size: 20rem;
        -webkit-transform:  translateX(-50%, -50%);
        -moz-transform:     translate(-50%, -50%);
        -ms-transform:      translate(-50%, -50%);
        -o-transform:       translate(-50%, -50%);
        transform:          translate(-50%, -50%);
        z-index: 2;
        color: white;
        color: rgba(255,255,255,0.75);
}

Answer 1

我在iframe的属性中缺少allow =“ autoplay”

<iframe id="video-player" class="video" width="560" height="315" src="https://player.vimeo.com/video/309741585" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen allow="autoplay"></iframe>
