废话不多说了直接给大家贴代码了。
代码如下：
<script language="JavaScript">
<!--
//js禁用某些键的代码
//www.jb51.net
function key(){
if(event.shiftKey){
window.close();}
//禁止Shift
if(event.altKey){
window.close();}
//禁止Alt
if(event.ctrlKey){
window.close();}
//禁止Ctrl
return false;}
document.onkeydown=key;
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;}
}
//禁右键
document.oncontextmenu = nocontextmenu; // for IE5+
document.onmou<a href="http://www.jb51.net/article/1141.html" target="_blank" class="infotextkey">sed</a>own = norightclick; // for all others
//-->
</script>1. oncontextmenu="window.event.returnValue=false" 将彻底屏蔽鼠标右键特效
| no |
2.
取消选取、防止复制3. onpaste="return false" 不准粘贴
4. oncopy="return false;" oncut="return false;" 防止复制
PS:JS防止后退,刷新,关闭的解决办法

<script language="javascript">
function RunOnBeforeUnload() {window.onbeforeunload = function(){ return '将丢失未保存的数据!'; } }
</script>
<body onload="RunOnBeforeUnload()">
刷新,关闭,后退,F5 测试
</body>
</html>虽然onbeforeunload这个事件已经Web标准被淘汰,但目前能实现这个效果的也就只有这个事件.还好浏览器都能很好的支持.
测试结果:
IE6.0,FireFox,Chrome通过
