Disable Copy or Paste action for text box?
Use
oncopy="return false"
onpaste="return false"
Email: <input type="textbox" id="email" oncopy="return false" onpaste="return false" ><br/>
Confirm Email: <input type="textbox" id="confirmEmail" oncopy="return false" onpaste="return false">

Check this fiddle.
$('#email').bind("cut copy paste",function(e) {
e.preventDefault();
});
You need to bind what should be done on cut, copy and paste. You prevent default behavior of the action.
