如何使用javascript退出浏览器的F11全屏

Question

有没有办法退出通过点击创建的全屏F11？

FullScreen: {
      _callback: null,
      enabled  : function () {
        return document.fullscreenEnabled ||
          document.webkitFullscreenEnabled ||
          document.mozFullScreenEnabled ||
          document.msFullscreenEnabled;
      },

      request: function (i) {
        if (i.requestFullscreen) {
          i.requestFullscreen();
        } else if (i.webkitRequestFullscreen) {
          i.webkitRequestFullscreen();
        } else if (i.mozRequestFullScreen) {
          i.mozRequestFullScreen();
        } else if (i.msRequestFullscreen) {
          i.msRequestFullscreen();
        }
      },

      element: function () {
        return document.fullscreenElement ||
          document.webkitFullscreenElement ||
          document.mozFullScreenElement ||
          document.msFullscreenElement;
      },

      exit: function () {
        if (document.exitFullscreen) {
          document.exitFullscreen();
        } else if (document.webkitExitFullscreen) {
          document.webkitExitFullscreen();
        } else if (document.mozCancelFullScreen) {
          document.mozCancelFullScreen();
        } else if (document.msExitFullscreen) {
          document.msExitFullscreen();
        }
      },

      onChange: function (fn) {
        if (document.fullscreenEnabled)
          document.addEventListener('fullscreenchange', fn);
        else if (document.webkitFullscreenEnabled)
          document.addEventListener('webkitfullscreenchange', fn);
        else if (document.mozFullScreenEnabled)
          document.addEventListener('mozfullscreenchange', fn);
        else if (document.msFullscreenEnabled)
          document.addEventListener('MSFullscreenChange', fn);
      },

      removeOnChange: function (fn) {
        if (document.fullscreenEnabled)
          document.removeEventListener('fullscreenchange', fn);
        else if (document.webkitFullscreenEnabled)
          document.removeEventListener('webkitfullscreenchange', fn);
        else if (document.mozFullScreenEnabled)
          document.removeEventListener('mozfullscreenchange', fn);
        else if (document.msFullscreenEnabled)
          document.removeEventListener('MSFullscreenChange', fn);
      },
    },

在全屏模式下使用F11:
Fullscreen.element()没有undefined效果Fullscreen.exit()。

在最新版本的 Firefox 和 Chrome 中尝试过。
