播放视频时如何使标题标题消失？

Question

我正在尝试让我的标题标题在我的视频播放时在 javascript 中消失。使用下面的代码，我可以让我的视频在播放完毕后消失。

// Background Video (hide)
const video = document.querySelector('video');
video.onended = function () {
video.style.display = 'none';
};

很遗憾，我无法在播放视频时让标题消失。下面的代码似乎没有完成这项工作。

   const header = document.querySelector('header');
   header.onplaying = function () {
   header.style.display = 'none';
};

任何帮助将不胜感激。

Answer 1

不应该是video.onplaying而不是header.onplaying吗？

const header = document.querySelector('header');
video.onplaying = function () {
   header.style.display = 'none';
};
