html网页全屏显示代码

最常见的是使用window.open的方法,直接打开全屏网页:
<script>
<!--
function fullwin(){
window.open("bigpage.html","bfs","fullscreen,scrollbars")
}
//-->
</script>

<center>
<form>
<input type="button" onClick="fullwin()" value="Open Full Screen Window">
</form>
</center> 
另外,如果想让已经打开的网页全屏,有以下两种方法:
1.使用ActiveX
<html>
<head>
<title>test</title>
<script language="JavaScript">
function Fkey(){
     var WsShell = new ActiveXObject('WScript.Shell')
     WsShell.SendKeys('{F11}');
}
</script>
</head>
<body>
<a href="javascript:Fkey()">to full</a>
</body>
</html>
2.使用window.open模拟当前页:
<SCRIPT language="JavaScript">   
function   toFull(){   
  if(window.name=="fullscreen")return;   
  var a =window.open("","fullscreen","fullscreen=yes")   
  a.location = window.location.href   
  window.opener=null   
  window.close()   
}   
</SCRIPT>   
<html>   
<body>   
<input type=button value="full" onclick=toFull()>   
</body>   
</html>
