如何将新浏览器实例设置为全屏模式，而不是在量角器中最大化

<button onclick="toggleFullScreen()">全屏模式</button>

function toggleFullScreen() {
  var doc = window.document;
  var docEl = doc.documentElement;

  var requestFullScreen = docEl.requestFullscreen || docEl.mozRequestFullScreen || docEl.webkitRequestFullScreen || docEl.msRequestFullscreen;
  var exitFullScreen = doc.exitFullscreen || doc.mozCancelFullScreen || doc.webkitExitFullscreen || doc.msExitFullscreen;

  if (!doc.fullscreenElement && !doc.mozFullScreenElement && !doc.webkitFullscreenElement && !doc.msFullscreenElement) {
    if (requestFullScreen) {
      requestFullScreen.call(docEl);
    }
  } else {
    if (exitFullScreen) {
      exitFullScreen.call(doc);
    }
  }
}

html, body {
  width: 100%;
  height: 100%;
  overflow: hidden;
}
