How to stop or pause video embedded in iframe

By re-adding a src file to the element, it will reset the iframe element to original state.

document.querySelectorAll("iframe").forEach((element) => {
  let iframeSrc = element.src;
  element.src = iframeSrc;
});

If there are any <video> element that can be easily accessed, (no Cross Origin issues), then we can simply pause the video by:

let videoElement = document.querySelector("video");

videoElement.pause();
