您可以使用请求全屏

img.addEventListener('click', function(ev) {
  let elem = ev.target
  if (!document.fullscreenElement) {
    elem.requestFullscreen().catch((err) => {
      alert(
        `Error attempting to enable fullscreen mode: ${err.message} (${err.name})`,
      );
    });
  } else {
    document.exitFullscreen();
  }
})
