Document.exitFullscreen()

Document.exitFullscreen() 方法用于让当前文档退出全屏模式（原文表述不准确，详见备注）。调用这个方法会让文档回退到上一个调用Element.requestFullscreen()方法进入全屏模式之前的状态。

备注: 如果一个元素A在请求进去全屏模式之前，已经存在其他元素处于全屏状态，当这个元素A退出全屏模式之后，之前的元素仍然处于全屏状态。浏览器内部维护了一个全屏元素栈用于实现这个目的。

语法

document.exitFullscreen();

示例

// 点击切换全屏模式
document.onclick = function (event) {
  if (document.fullscreenElement) {
    document.exitFullscreen()
  } else {
    document.documentElement.requestFullscreen()
  }
};
