防止复制粘贴选项 [英] Prevent Copy Paste options
问题描述
大家好，
我正在创建一个文档管理系统。这是客户的要求。
1）当我们点击创建链接时，文档应该在浏览器中打开 - 完成
2）防止从某些外部文档复制并粘贴到系统文件 - 防止右键单击和cntrl c反之亦然
3）应用程序中的复制/粘贴应该可用.--请指导我最后一点如何进行此操作。
防止右键单击...
< script >
var isNS =（navigator.appName ==Netscape）？ 1：0;
if（navigator.appName ==Netscape）document.captureEvents（Event.MOUSEDOWN || Event.MOUSEUP）;
函数mischandler（）{
返回false;
}
函数mousehandler（e）{
var myevent =（isNS）？ e：事件;
var eventbutton =（isNS）？ myevent.which：myevent.button;
if（（eventbutton == 2）||（eventbutton == 3））return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;

Hi All,
I am creating a Document Management System.Below are the requirment from the client.
1) When we click on create link a document should get open within the browser - Done
2) Prevent copy from some external document and paste in the document of the system - Prevented right click and cntrl c and vice versa
3) Copy/Paste within the application should be available.-- Please guide me on the last point how to go ahead of this.
To Prevent right Click ...
<script> var isNS = (navigator.appName == "Netscape") ? 1 : 0; if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP); function mischandler(){ return false; } function mousehandler(e){ var myevent = (isNS) ? e : event; var eventbutton = (isNS) ? myevent.which : myevent.button; if((eventbutton==2)||(eventbutton==3)) return false; } document.oncontextmenu = mischandler; document.onmousedown = mousehandler; document.onmouseup = mousehandler; </script>
At body tag
<body oncontextmenu="return false" onselectstart="return false" öndragstart="return false"></body>
To Prevent Copy and Paste alone
in java script
function killCopy(e){ return false } function reEnable(){ return true } document.onselectstart=new Function ("return false") if (window.sidebar){ document.onmousedown=killCopy document.onclick=reEnable }
in html body tag
ondragstart="return false" onselectstart="return false" oncontextmenu="return false"
