不言Original: 2018-07-03 17:54:511769browse

This article shares with you the detailed code for implementing full screen in various browsers using js. Friends who are interested can refer to it.

Modern browsers include ie11, which can be directly implemented using the h5 full-screen api
Lower versions of IE need to be implemented through ActiveX plug-ins;

//Directly upload the code

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title></title>
  </head>
  <body>
    <button onclick="fullScreen()">现代浏览器全屏</button>

    <button onclick="exitScreen()">现代浏览器退出</button>

    <button onclick="iefull()">低版本ie全屏</button>
  </body>
  <script src="js/jquery-2.1.1.js" type="text/javascript" charset="utf-8"></script>
  <script type="text/javascript">
    //全屏
    function fullScreen(){
      var el = document.documentElement;
      var rfs = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullscreen;   
        if(typeof rfs != "undefined" && rfs) {
          rfs.call(el);
        };
       return;
    }
    //退出全屏
    function exitScreen(){
      if (document.exitFullscreen) { 
        document.exitFullscreen(); 
      } 
      else if (document.mozCancelFullScreen) { 
        document.mozCancelFullScreen(); 
      } 
      else if (document.webkitCancelFullScreen) { 
        document.webkitCancelFullScreen(); 
      } 
      else if (document.msExitFullscreen) { 
        document.msExitFullscreen(); 
      } 
      if(typeof cfs != "undefined" && cfs) {
        cfs.call(el);
      }
    }
    //ie低版本的全屏，退出全屏都这个方法
    function iefull(){
      var el = document.documentElement;
      var rfs = el.msRequestFullScreen;
      if(typeof window.ActiveXObject != "undefined") {
        //这的方法 模拟f11键，使浏览器全屏
        var wscript = new ActiveXObject("WScript.Shell");
        if(wscript != null) {
          wscript.SendKeys("{F11}");
        }
      }
    }
    //注：ie调用ActiveX控件，需要在ie浏览器安全设置里面把 ‘未标记为可安全执行脚本的ActiveX控件初始化并执行脚本&#39; 设置为启用
  </script>
</html>

Note: In actual application, the full-screen function applicable to each browser can be realized by distinguishing ie11 ie10 and other browsers, and controlling the display and hiding of buttons;
