这篇文章主要讲述通过js来实现html页面的全屏显示，以及退出全屏展示的方法。分享给大家查考，具体代码实现如下：

js设置页面全屏

function launchFullScreen(element) {  
   if (element.requestFullscreen) {
      element.requestFullscreen();
    } else if (element.msRequestFullscreen) {
      element.msRequestFullscreen();
    } else if (element.mozRequestFullScreen) {
      element.mozRequestFullScreen();
    } else if (element.webkitRequestFullscreen) {
      element.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);
    }
}

Js退出全屏:

function cancelFullScreen() {  
   if (document.exitFullscreen) {
      document.exitFullscreen();
    } else if (document.msExitFullscreen) {
      document.msExitFullscreen();
    } else if (document.mozCancelFullScreen) {
      document.mozCancelFullScreen();
    } else if (document.webkitExitFullscreen) {
      document.webkitExitFullscreen();
    }
}
