Answer 1

Based on answer @KanakSinghal but without blocked all keys and with blocked cut event

$('.readonly').keydown(function(e) {
  if (e.keyCode === 8 || e.keyCode === 46)  // Backspace & del
    e.preventDefault();
}).on('keypress paste cut', function(e) {
  e.preventDefault();
});

P.S. Somebody knows as cut event translate to copy event?
