一、禁止复制文字代码 
<body leftmargin=0 topmargin=0 oncontextmenu='return false' ondragstart='return false' onselectstart ='return false' onselect='document.selection.empty()' oncopy='document.selection.empty()' onbeforecopy='return false' onmouseup='document.selection.empty()'> 

二、真正的屏蔽鼠标右键 

<script language="JavaScript"> 
<!-- 

if (window.Event) 
document.captureEvents(Event.MOUSEUP); 

function nocontextmenu() 
{ 
event.cancelBubble = true 
event.returnValue = false; 

return false; 
} 

function norightclick(e) 
{ 
if (window.Event) 
{ 
if (e.which == 2 || e.which == 3) 
return false; 
} 
else 
if (event.button == 2 || event.button == 3) 
{ 
event.cancelBubble = true 
event.returnValue = false; 
return false; 
} 

} 

document.oncontextmenu = nocontextmenu; // for IE5+ 
document.onmousedown = norightclick; // for all others 
//--> 
</script>

三、

<SCRIPT LANGUAGE=javascript> 
function click() {alert('禁止左键复制！') } 
function click1() {if (event.button==2) {alert('禁止右键点击~！') }} 
function CtrlKeyDown(){if (event.ctrlKey) {alert('非法拷贝将损害您的系统！') }} 
document.onkeydown=CtrlKeyDown; 
document.onselectstart=click; 
document.onmousedown=click1; 
</SCRIPT> 

把上面的代码放到</head> 与<body> 之间我已经调试过了 没问题 

禁止保存网页 

<NOSCRIPT><IFRAME src=Example132.htm></IFRAME></NOSCRIPT> 

下面这段代码，就能搞定在网页中又禁止复制、又禁止键盘复制、还能禁止选择。 
<script language="Javascript"> 
document.oncontextmenu=new Function("event.returnValue=false"); 
document.onselectstart=new Function("event.returnValue=false"); 
</script>

四、

onselect="document.selection.empty()"//禁止选中 
oncopy="document.selection.empty()"//禁止复制 
下面给你个演示: 
<html> 

<head><title>禁止右键和禁止使用复制键</title> 

<script language="javascript"> 

function onKeyDown() 
{ 
if ((event.keyCode==116)||(window.event.ctrlKey)||(window.event.shiftKey)||(event.keyCode==122)) 
{ 
event.keyCode=0; 
event.returnValue=false; 
} 
} 

function yxl() { 
if(window.event.altKey) 
{ 
window.event.returnValue=false; 
} 
} 
document.onkeydown=yxl ; 

</script> 

</head> 

<!--在网页中加上下面代码//--> 

<body onkeydown="onKeyDown()" oncontextmenu="return false"> 
嘿嘿，把我复制走吧，我跟你拉！呵呵 
</body> 

</html>

五、

禁止复制代码 
<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; onresize=MM_reloadPage; }} 
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload(); 
} 
MM_reloadPage(true); 
//--> 
</script> 
</head> 
<body leftmargin=0 topmargin=0 onmousemove='HideMenu()' oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false" onmouseup="document.selection.empty()"> 
<noscript><iframe src="/*>";</iframe></noscript>
禁止下载图片:
可以做双层保护第一，oncontextmenu="return false"放在<body>里 例子：<body  oncontextmenu="return false" bgcolor="808080" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" >作用：简单的方式右健弹出第二，现在IE或者QQ浏览器都有自己的IE插件 鼠标放到图片会有插件提示你保存解决办法：方法一(针对单独的图片)：方法二(针对整个页面中的图片有效)：<meta http-equiv="imagetoolbar" content="false">这样的话可以做双层保护的
