廢話不多說了直接給大家貼代碼了。
代碼如下:
<script language="JavaScript"> <!-- //js禁用某些鍵的代碼 //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;} } //禁右鍵 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>
<body onselectstart="return false"; onpaste="return false";>
1. oncontextmenu="window.event.returnValue=false" 將徹底屏蔽鼠標右鍵特效
<table border oncontextmenu=return(false)><td>no</table> 可用於Table
2. <body onselectstart="return false"> 取消選取、防止復制
3. onpaste="return false" 不准粘貼
4. oncopy="return false;" oncut="return false;" 防止復制
PS:JS防止後退,刷新,關閉的解決辦法
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html><head> <title> New Document </title> </head> <script language="javascript"> function RunOnBeforeUnload() {window.onbeforeunload = function(){ return '將丟失未保存的數據!'; } } </script> <body onload="RunOnBeforeUnload()"> 刷新,關閉,後退,F5 測試 </body> </html>
雖然onbeforeunload這個事件已經Web標准被淘汰,但目前能實現這個效果的也就只有這個事件.還好浏覽器都能很好的支持.
測試結果:
IE6.0,FireFox,Chrome通過
