For this I use onKeyDown event. See the following code
that disables CTRL C and CTRL V.

Note that this is not enough to prevent COPY/PASTE
in a text field, since the user can use CTRL INS, SHIFT INS
or simply use the context menu (right click on text field).

<script language="javascript">

function onKeyDown() {
  // current pressed key
  var pressedKey = String.fromCharCode(event.keyCode).toLowerCase();

  if (event.ctrlKey && (pressedKey == "c" || 
                        pressedKey == "v")) {
    // disable key press porcessing
    event.returnValue = false;

} // onKeyDown


<form name="aForm">
<input type="text" name="aText" onkeydown = "onKeyDown()">

how to disable ctrl+c:

That shortcut is handled by the operating system. It never reaches the browser and so the browser has no opportunity to pass it to the web page.

IE only:

Add the following code to your BODY tag:

ondragstart="return false" onselectstart="return false"

This code to disable ctrl (control).once you disable the ctrl other all event such as ctrl+C,ctrl+A etc. are disable.

<script language='javascript'> //function for to disable ctrl event of the page.
	function document.onkeydown() 
		if ( event.keyCode==17) //17 is ascii code for ctrl
			event.keyCode = 0; 
			event.cancelBubble = true; 
			return false; 

This code to disable ctrl (control)

The bad news is that your code is not cross-browser compatible.
Even in IE, it doesn't prevent copying with other keystrokes or with the mouse. It also doesn't deal with <iframe>s [and possibly <frame>s as well, but I didn't bother to test].

The good news is that this thread had been dead for almost two years before you resurrected it, so the prior participants are unlikely to care. Plus, it gives a link to a page which explains in some detail why the 'view source' part of the request [which you didn't address] is not possible.

Shanti's Attempt is quite good..
But how to disable Copy and Paste events using Mouse..

garyrichard, disable the mouse right click with:

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;


In addition to the above example you can also add the below commands into your HTML <body> tag. Which will disable the keyboard and mouse in Internet Explorer.

oncontextmenu="return false" onselectstart="return false" ondragstart="return false"

Thanks a lot Quasimodo8. it's working fine.

Just change your tag <body> or <body whatever here> with

<body expr:class='&quot;loading&quot; + data:blog.mobileClass' oncontextmenu='return false;' onkeydown='return false;' onmousedown='return false;' style='-moz-user-select: none;'>

But it's still easy, some people just use view-source:yourUrl, I just need the answer about how to disable view-source:Url or encript our html code, thanks

@Ahmad_10, please create a new post instead of pull a very old post up.

If you want to disable view source from a browser menu, you will have to force open a new window with menubar/toolbar disabled. However, it is still defeated easily if the person really knows how to deal with "javascript." Therefore, there is no permanent way to do so.

You cannot prevent a user from seeing or copying the source code of your web pages. You can do some things to make it difficult for a human to read the code, but they don't really help much. In the end, you have to send valid HTML to the user's browser, and all the user has to do is select "Save" from the File menu and he has your code on his computer where he can do as he pleases with it.
