如何在第一次点击后才显示html视频控件？

Question

我有一个页面上的视频部分，我已经编码。我想隐藏视频控件(下面的水平条与播放按钮和进度条)，直到视频被单击。它应该是隐藏的，应该只在视频被点击后显示。我该怎么做呢？谢谢

<section class="video-background text-center pb-0 mt-9">
    <div class="container px-0">
    <h2 class="mt-5 mb-4">Take a look at our video!</h2>
    <p class="mb-5 font-weight-normal">One click away</p>
    <div class="position-relative mx-auto px-0 mb-6" 
    >
        <div class="mx-auto" [ngClass] = "{ 'darken' : !btnHide }" (click)="isPlayed ? pauseVideo() : playVideo();" >
        <video #videoEl id="videoPlayer" class="videoDimension py-0 vid-shadow" 
        src="https://www.youtube.com/watch?v=LXb3EKWsInQ"
         allowfullscreen controls></video>
        </div>
        <button (click)="playVideo();" *ngIf="!btnHide" class="btn btn-primary btn-lg pl-5 pr-2 py-2 play-button">Watch video<i class="ml-4 fa fa-caret-right" aria-hidden="true"></i></button>
    </div></div>
</section>

Answer 1

从视频元素中删除controls属性，然后在视频元素的onclick侦听器setAttribute("controls", "true")中。
