廢話不多說了直接給大家貼程式碼了。
程式碼如下：
<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" 將徹底屏蔽滑鼠右鍵特效
| no |
2.
取消選取、防止複製3. onpaste="return false" 不准貼上
4. oncopy="return false;" oncut="return false;" 防止複製
PS:JS防止後退,刷新,關閉的解決方案

<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>雖然onbeforeunload這個事件已經Web標準被淘汰,但目前能實現這個效果的也就只有這個事件.還好瀏覽器都能很好的支援.
測試結果:
IE6.0,FireFox,Chrome透過
