Is there a cross browser way to prevent cut, copy and paste on a website in plain Javascript?

Question

I found an answer, but it was for JQuery. Here is the link:

http://jquerybyexample.blogspot.com/2010/12/disable-cut-copy-and-paste-function-for.html

: I want something in plain Javascript which work on chrome, latest firefox, safari, and IE 8 and 9.

Update

Due to all the negative comments saying that this is a bad idea for an internet site I can only say "I agree". Please note that this is for an "intranet" application where cut, copy, and paste need to be overidden as the default browser behaviour for cut copy and paste needs to be customized to handle embedded tags in a rich text area

Answer 1

a good way

var D=document.getElementById('b4');

if(D.addEventListener){
D.addEventListener('paste',function(e){false;e.preventDefault();},false);}
else{
D.attachEvent('onpaste',function(){return false;});}

warning : code must be under html target/s , just before the close body tag for example
