实现效果

JS实现浏览器全屏

实现方式对比

1、ActiveXObject 只支持IE

2、FullScreen(HTML方法)支持 Chrome 15 / Firefox Nightly / Safari 5.1
备注:方法二 FullScreen JavaScript API 目前仍是草案,实现这个 API,更确切来说是具有这项功能的浏览器有:Chrome 15 / Firefox Nightly / Safari 5.1。
其他方法:flash特性(google关键字 flash 全屏)

代码示例

<html>
<head>
    <script type="text/javascript" language="javascript"> 
  //方法一:ActiveXObject 只支持IE
  //方法二:FullScreen(HTML方法)支持 Chrome 15 / Firefox Nightly / Safari 5.1
  //备注:方法二 FullScreen Javascript API 目前仍是草案,实现这个 API,更确切来说是具有这项功能的浏览器有:Chrome 15 / Firefox Nightly / Safari 5.1。
   
function fullScreen() { 

  var element= document.documentElement; //若要全屏页面中div,var element= document.getElementById("divID");
  //IE 10及以下ActiveXObject
  if (window.ActiveXObject)
  {
    var WsShell = new ActiveXObject('WScript.Shell') 
    WsShell.SendKeys('{F11}'); 
  }
  //HTML W3C 提议
  else if(element.requestFullScreen) {  
    element.requestFullScreen();  
  }
  //IE11
  else if(element.msRequestFullscreen) {

  // Webkit (works in Safari5.1 and Chrome 15)
  else if(element.webkitRequestFullScreen ) {
