通过下面的代码，即可实现页面全屏蔽功能：
<DIV id=divTitle style="FONT-SIZE: 16px">禁止复制代码1</DIV>
<SCRIPT LANGUAGE=javascript>
function click() {
alert('禁止你的左键复制！') }
function click1() {
if (event.button==2) {alert('禁止右键点击~！') }}
function CtrlKeyDown(){
if (event.ctrlKey) {alert('不当的拷贝将损害您的系统！') }}
document.οnkeydοwn=CtrlKeyDown;
document.onselectstart=click;
document.οnmοusedοwn=click1;
</SCRIPT>
<SCRIPT language=javascript></SCRIPT>
<DIV id=divTitle style="FONT-SIZE: 16px">禁止复制代码2</DIV>
<script language="JavaScript" type="text/JavaScript">
<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; οnresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
//-->
</script>
</head>
<body leftmargin=0 topmargin=0 οnmοusemοve='HideMenu()' οncοntextmenu="return false" οndragstart="return false" onselectstart ="return false" οnselect="document.selection.empty()" οncοpy="document.selection.empty()" onbeforecopy="return false" οnmοuseup="document.selection.empty()">
<noscript><iframe src=*></iframe></noscript>
// 彻底屏蔽右键菜单
document.oncontextmenu = function()
{
window.event.returnvalue=false;
alert("对话框内容");
return false;
}
或者：
在<body>中加入以下代码： 效果等价（我感觉还是加下面的好，多容易啊）
<body οnmοusemοve=/HideMenu()/ οncοntextmenu="return false" οndragstart="return false" onselectstart ="return false" οnselect="document.selection.empty()" οncοpy="document.selection.empty()" onbeforecopy="return false" οnmοuseup="document.selection.empty()">
